Brass Grade & Properties

Brass C260 (Cartridge Brass)

Brass C260 is a copper-zinc alloy with a zinc content of approximately 30%, also known as cartridge brass.

It has very good ductility as well as corrosion and wear resistance, high strength and low friction properties.

These properties allow brass to be used in a wide range of applications such as: rivets, syringe parts, hinges, watch parts and radiator cores.

Grade Fatigue Strength Tensile Strength, Yield Elongation(%) Hardness(Brinell)
C260 90 MPa 75 MPa 68% 53

Brass C360 (Free-Cutting Brass)

Brass 360 is a copper-zinc alloy, also known as free-machining brass due to its extremely high machinability.

It has exceptional strength and corrosion resistance and is often used for turning and milling operations or for welding.

Grade Fatigue Strength Tensile Strength, Yield Elongation(%) Hardness(Brinell)
C360 138 MPa 124 - 310 MPa 53% 63 - 130

Industrial Applications for Brass

As a rule, brass is an alloy of copper-zinc. The properties of brass can vary greatly depending on the ratio of copper to zinc.

Brass has excellent corrosion resistance and low friction coefficient, and its applications are very wide, especially brass turned component parts.

Surface Finish for Brass Parts

Due to the natural electrical conductivity, corrosion resistance and low friction coefficient of brass, these properties make it usually unnecessary to be coated when applied as a functional part.

However, when used as decorative cosmetic part, surface finishes need to be considered.

Polishing, buffing or honing: Brass is often used as a decorative cosmetic component.

This is because different proportions of brass alloys can boast different colors.

Polished finish results in a smoother and shiny surface. 

Electroplating: Brass is easy to work with and its newly finished surfaces often look attractive.

And with additional plating processes, its surface finish and properties are further improved.

Cost-saving Advice

Brass is also a relatively expensive material, and it is necessary to consider the principles of product design optimization in advance.

Therefore, working with a competent factory or manufacturer will bring you more value-added services.

cost saving

Design principles: The design following the applicable DFM principles can not only optimize the manufacturing process to save production costs, but also effectively prevent unnecessary rework in the production process.

Material selection: According to the actual application needs, choose the appropriate material or material grade to achieve the goal of the best cost effective.

For example, high strength brass is more suitable for functional parts.
