Perth Brass Machining

What is Brass?

Brass is an alloy of copper and zinc that is easy to machine, durable, and useful for various applications. 


Generally, brass is created by mixing 67% copper and 33% zinc. However, the percentage of each element can change drastically based on customer specifications and use cases.

Changes made to the mix can affect the mechanical, electrical, and chemical properties of the alloy.


Brass can be sourced in round and hex bars, and is machinable to customer requirements.

Brass Properties

Brass Advantages and Disadvantages

Brass is a strong and durable alloy that is excellent for machining. Manufacturers sometimes refer to brass as “100% machinability”.


Brass’s main advantages are:


  • Decorative aesthetics and gold appearance

  • Corrosion resistance

  • High electrical conductivity

  • Long-lasting and durable

  • Low friction

  • General and tensile strength

  • Shear and impact resistance

  • Dimensional stability

  • Eco-friendly (machining scrap is recyclable)

  • Easy and efficient to machine


The main disadvantage of brass is that it is prone to tarnish and can require maintenance. Furthermore, using ammonia to clean brass can cause stress fractures. Steel is also stronger and harder than brass.
