Brass

What is brass?

Brass is an alloy of copper and zinc, which stands out thanks to its gold-like lustre and its versatile mechanical properties. It has been used for various applications for centuries and plays an important role in modern industry.

Properties of brass

High corrosion resistance

Brass is extremely resistant to environmental influences and oxidation. This property makes it particularly suitable for use in damp and maritime environments.

Good electrical and thermal conductivity

Thanks to its high copper content, brass possesses excellent electrical conductivity, which means it is frequently used in electrical connectors and circuit boards.

High strength and hardness

The mechanical strength of brass depends on the composition of the alloy. By adding other metals such as lead or aluminium, the properties can be specifically adjusted.

Easy machinability and aesthetics

Brass is easy to machine and can be precisely processed both by turning and by milling. Its characteristic lustre also makes it attractive for decorative applications.

Applications of brass

Metalworking and mechanical engineering

Brass is a preferred material for CNC turning and milled parts. Its excellent machinability enables the production of highly precise components for machines and systems.

Sanitary and pipeline construction

Due to its corrosion resistance, brass is frequently used for fittings, valves and pipes in the sanitary sector. It is insensitive to limescale deposits and offers a long service life.

Electrical industry

Brass is found in switches, connectors and electrical contacts. The combination of good conductivity and mechanical strength makes it an ideal material for the electrical industry.

Brass alloys

Brass is produced in various compositions that offer specific properties:

• Soft brass: High copper content, particularly malleable and easy to solder.
• Hard brass: Higher zinc content, increases strength and hardness.
• Special alloys: Brass with aluminium, lead or tin for improved properties, e.g. increased corrosion resistance or better machinability.

Machining of brass

The CNC machining of brass offers numerous advantages:

• Tools: Carbide or coated cutting tools are ideal for precise machining.
• Coolant: Reduces material adhesion and improves surface quality.
• Milling strategies: High speeds and precise feeds ensure optimum machining results.

Sustainability and recycling

Brass is 100 % recyclable without losing quality. Recycling brass saves energy and raw materials and contributes to the sustainable use of metals. Because of these properties, brass is an environmentally friendly choice for numerous industries.

Conclusion

Brass is an extremely versatile material with a broad range of applications. Its combination of strength, corrosion resistance and good machinability makes it an indispensable material in metalworking, mechanical engineering and many other branches of industry.
