Milners Repetition

Resources

Mild Steels

Mild steels are a general purpose engineering steels which are economical and easy to work with. They are typically used for machined parts or shafts and can be case hardened and weld readily.

M1020, S1214 and S12L14 are common and widely used engineering steels and are supplied in cold drawn or turned and polished condition.

Stainless Steel

Stainless steel is used where corrosion resistance is required. We machine most grades of available stainless steel, usually 303, 304 and 316

• 

High Tensile Steel

High tensile steels have alloying elements and heat treatment process that improves strength and durability of the steel. We process high tensile steels for both engineering and fabrication.

Engineering grades we commonly process include:

• 4140
• 4340
• EN26

Aluminium

Aluminium is a widely used engineering material. Grades of aluminium include 2011, 6060. It has many desirable properties such as:

• 

• light weight
• corrosion resistance
• good machinability
• Can be welded and brazed
• good strength and tensile properties

Plastic

Engineering plastics have a wide range of applications in Australian industry and are used on water fronts, the food and beverage industry, engineering, farming and mining.

We machine a range of Engineering Plastics rod including, Nylon, Acetal, UHMWPE, HDPE Polypropylene, PVC, PETP and PETP-GL

Brass

Brass is often the preferred choice for high volume repetition machining of fittings and small parts. Brass is quick and easy to machine and offers good corrosion resistance without further plating or coating. Brass is available in grades including 385, 352 and 360. It is also readily available in Hex and Square shapes for machining of fittings and fasteners.

Bronze

Bronze is an alloy of copper and tin. It is widely used for plain bearings due to its strength and toughness. Plain bearings are ideal for applications where room is limited and speeds are slow. The most common grades for engineering purposes are LG2 and PB1.

Copper

Copper is a ductile metal with very good thermal and electrical conductivity.
