Precision Brass Machining

C360 & C353 Custom Parts Manufacturing

Brass is a versatile copper alloy that combines excellent machinability with outstanding corrosion resistance and electrical conductivity. This golden-colored metal offers a unique balance of properties that make it valuable for precision machined components.The addition of zinc to copper creates brass's distinctive properties: high strength, good ductility, and natural corrosion resistance.

Brass maintains its mechanical properties across a wide temperature range and resists wear in demanding applications. Its natural lubricity helps reduce friction in moving parts, while its non-magnetic properties make it suitable for electrical applications.

One of brass's most significant advantages is its exceptional machinability. The metal cuts cleanly, producing smooth surface finishes with minimal tool wear. This characteristic allows for precise machining of complex geometries while maintaining tight tolerances. The material also accepts a variety of platings and surface finishes, enhancing both its appearance and performance characteristics.
