QUALITY THROUGHOUT ALL ASPECTS OF MANUFACTURE
Principle of the Extrusion Process
(Brass, Copper and Aluminium)
Manufactured to ISO 9001
The extrusion process uses continuous cast billet which has had
All Kormax bronze products are manufactured using continuous or centrifugal casting methods. Bronze produced
marks. These billets are pre-heated to approximately
by either of these methods has significant advantages over sand-cast material. Some of these advantages are:
• Increased tensile strength and wearing qualities – by up to 35%
• Higher hardness and ductility
• Freedom from porosity
• Fine grain structure
• Improved machining properties and longer tool life
• Less ‘clean-up’ allowance needed for machining
All Kormax brass, copper and aluminium products are extruded. This manufacturing process is also well known for
the high quality material produced. A brief explanation of these manufacturing processes is given below.
the outside diameter machined to remove oxides and other casting
650-700°C before loading into the extrusion press. Once heated,
the billet is positioned on top of the die and the extrusion press
container lowered down over it. At this point 1000 tonnes of
pressure is applied by the extrusion press causing the metal to be
extruded through the die. The size and shape of the die determines
the size and shape of the extruded rod.
Broad Range of Lengths Available
Kormax clients value the flexibility offered by our user-friendly cutting service. Meeting customer specific
requirements is our specialty, that’s why we cut material to suit almost any length requirement – at no extra cost.
The following table gives information about the standard lengths that our products are manufactured in.
MANUFACTURING PROCESSES
Principle of Continuous Casting
(Bronze up to 12” diameter, all Cast Iron)
Molten metal is poured from a furnace into a crucible which is
cemented to the neck of a graphite die. The lower half of the die
is water cooled so that the metal then sets in this section and is
withdrawn through two sets of rollers. A flying saw mounted below
the roller cuts the bar to the required length. Continuous cast bar
has greatly improved physical properties when compared with
normal sand-cast material. Because of the bottom pouring
conditions and rapid cooling that the metal receives in the cooling
zone, inclusions are completely eliminated, grain structure is tight
and even, giving excellent pressure tightness qualities.
Principle of Centrifugal Casting
(Bronze approx. 8” to 48” diameter)
Molten bronze is poured from a furnace into a pilot ladle which
directs the stream of metal into a horizontal spinning die. This die
determines the OD of the casting produced, and the amount of
molten bronze fed to the die determines the wall thickness.
When the die is fully charged with the correct amount of metal it
continues spinning for a predetermined period. On completion
of the spinning process the die is removed, then the casting is
withdrawn, proof machined and inspected.

1. This information applies to bronze up to 10” diameter – all larger diameters have a maximum length of 1000mm.
2. Large diameters may be available in full lengths, check by calling Kormax on 0800 789 987.
While some applications may call for multiple long lengths of material to maximise the bar-feed capacity of a CNC
machine, others may require only a short piece for one-off repair work. Either way we’ll be able to help.
We also carry a wide range of LG2 and 954 product in 15” (381mm) lengths – these are particularly useful in
jobbing, small-run manufacture and repair type applications. They also facilitate ease of handling and shipping, and
are a practical size to hold in a lathe chuck.
Analysis of Sample Material
If you remove a worn bronze or brass component and are unable to identify what type of material it is, Kormax offers
a free metallurgical analysis service (when you purchase the replacement material from us.)

Bronze is the name for metal usually consisting of
80 - 95% copper
with the balance made up of one or more
other metals, such as tin, silicon, nickel,
aluminium, iron, zinc or manganese.
3000 BC
ancient man discovered
that adding a small
percentage of tin to
copper greatly increased it’s
strength, hence the beginning
of the
‘Bronze Age’.
Bronze is a
favoured material
when strength
corrosion
resistance are
and
called for.

Overview
5/8
LG2 Bronze is one of the most commonly used grades of bronze in the New Zealand industry. It has medium
7/8
strength, excellent machining properties, and is suitable for bearings, gears and other components used in
relatively light duty applications. Although LG2 is often referred to as phosphor bronze, it is in fact a leaded
gunmetal. Only the ‘PB’ group of bronzes (PB1, PB2 etc.) can truly be called phosphor bronze. All Kormax LG2
bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness
and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and
is free from porosity.

954
Alloy 954 is a high strength aluminium bronze that is widely used in heavy duty applications such as forestry,
mining, construction & marine. It is a very hard material which has excellent strength and wear resistance, yet still
retains good machining properties. Alloy 954 also has good resistance to impact loading, but it should be noted that
proper lubrication is necessary to prevent metal to metal contact. Inadequate lubrication is likely to cause scoring
or ‘galling’, and consequent damage to the bronze component and/or other moving parts. General corrosion
resistance is good but de-luminification may occur under some circumstances. All Kormax 954 Aluminium Bronze
is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and
strength is superior to sand-casting methods. This also means that the material has a fine grain structure
and is free from porosity.

Size Availability
Kormax standard stock of PB1 Phosphor Bronze covers most requirements from 1/2” through to 10” in diameter,
with larger sizes (up to 48”) available to order. Although Kormax is committed to having New Zealand’s largest range
of stock of PB1, it is a somewhat specialised material and certain sizes may only be available by special order.
All Kormax PB1 Bronze bar has machining allowances added to the sizes quoted. To use 4-1/2” x 2-1/2” hollow bar
as an example, this material would measure approximately 4.570” OD x 2.440” ID as supplied (see table below).
Therefore this allows finished components measuring 4-1/2” OD x 2-1/2” ID to be easily manufactured from
and hollow bar).

Overview
Kormax carries a comprehensive range of sintered bronze bushes in both metric and imperial sizes, as well as
solid and hollow bars. Other shapes such as thrust washers, flanged bushes and flat plates are available by indent,
and also solid and hollow round bar up to 8” diameter.
Sintered Bronze Manufacturing Process
Sintered bronze is manufactured using the ‘powder metallurgy’ process which involves fine bronze powder being
blended with other additives then compacted in a die under high pressure. Following this, the component is
heated to a high temperature so that the powder particles bond together to form a sintered part, then it is sized to
obtain the exact dimensions and close tolerances desired. The final step in the manufacturing process is vacuum
impregnation, which fills the pores with lubricant.
The Principle of Self Lubrication
Sintered bronze is in effect a ‘metallic sponge’ with the lubricant being stored in the interconnected pores of the
metal. The oil storage capacity of standard sintered bronze is usually 19 – 22% of its total volume. When a
component is in use it is inevitable that there is some friction, which in turn creates an increase in temperature.
With this rise in temperature, oil is forced out of the pores due to the volumetric expansion of oil being much higher
than that of bronze. The flow of oil out of the pores to the bearing surface ensures constant lubrication while a
machine is in use. When shaft rotation stops, cooling of the bearing occurs and the oil is drawn back into the pores

a sintered bronze bush is sufficient to give good lubrication over a period of many years.

385 Brass
31/32
33
Brass is a bright yellowy gold metal
consisting mainly of copper and zinc.
The copper content is
usually in the range of
55 -70%
The addition of zinc to copper results
in a metal of increased strength
and hardness when compared to
unalloyed copper.
Brass is a highly machinable,
form-able and corrosion
resistant metal. Commonly
used for plumbing fittings,
architectural hardware,
fasteners and many more
machined parts.
The earliest brass, called calamine brass,
dates to Neolithic times. It was probably made
by reduction of mixtures of zinc ores and copper ores.
The malleability and
traditionally attributed
acoustic properties of
brass have made it
the metal of choice for musical instruments.

Copper is a naturally
occurring soft,
malleable metal.
Copper has a reddish,
orange lustre.
Gold is the only other
naturally occurring metal
that has a colour other than white or grey.
Copper was the first metal to
be used widely by man, over
5,000
years ago.
Today Copper is the third
most
commonly used metal
in the world, following Iron and Aluminium.
Copper was favoured in early times for it’s
formability and corrosion resistance.
These attributes are still valued, but
thermal and
electrical conductivity
it is copper’s
that makes it so widely used today.

Silver Steel
43/44
Cast iron was first
used in Asia circa
600bc
then about 2000 years later its use gradually
spread to Europe, England and the USA.
Used widely in architectural and
structural applications until steel
began to take over in late 1800’s.
Ironbridge
in Shropshire,
England was
the first
major bridge
in the world to be constructed wholly of
cast iron, built between 1777-1780.
Built from
almost
385
tonnes
of metal with nearly
1700 individual components
the bridge is still open to pedestrians today.
Silver steel is sometimes referred to
as Tool Steel (UK) or Drill Rod (USA).
Supplied as a centreless round bar
in annealed (soft) form. It is easily
worked into shape then hardened
for uses such as punches,
shafts, pins and more.

Cast Iron
3D
4E
Overview
Kormax 4E Continuous Cast Iron bars consist of a uniform pearlitic structure from surface to core. As a continuous
cast iron bar it has a fine grain structure combined with the fine graphite flake size and dense homogeneous
structure. The material is well suited for high speed machining and is suitable in applications that demand the ability
to withstand high pressures without leaking.
Kormax cast iron is also available in a ductile iron that has a stock grade of 3D and is otherwise known as spheroidal
graphite or nodular iron. The material is high strength, ductile and more readily machined than other styles of cast iron.
Its properties include being highly elastic and resistant to impact and is suitable for applications involving thermal and
mechanical shock. 3D Ductile Iron is also the preferred choice for making hydraulic cylinder components.

Aluminium

47/48
Aluminium is a silvery white,
non-magnetic, ductile,
soft, metal. It is a chemical
element in the boron group.
Aluminium is the most
abundant metal in
the world. It is the third
most common element in the
earth’s crust, making up around 8% of it.
Pure aluminium is extremely rare. It is so
chemically reactive that native specimens are
limited to extreme reducing environments.
Instead, it is found combined in over 270
different minerals.
Aluminium was first produced in an impure
form by Danish physicist
Hans Christian Orsted in
1825
Structural components made from aluminium
are vital to the transportation, aerospace and
construction sectors due to its
low density and corrosion
resistant properties.
