Why Choose Brass and Copper Alloys?

The primary benefits of brass and copper alloys in CNC machining are their exceptional machinability, corrosion resistance, and electrical/thermal conductivity.

Superb Machinability: Brass, particularly alloys like C36000 (FreeCutting Brass), is renowned for its excellent machinability. It allows for highspeed machining, producing clean cuts with minimal tool wear. This results in shorter production cycles, superior surface finishes straight off the machine, and lower overall manufacturing costs.
Inherent Corrosion Resistance: These alloys naturally resist corrosion from water, atmospheric exposure, and many chemicals. This makes them perfect for marine applications, plumbing fixtures, and fluid handling systems where longevity and reliability are nonnegotiable.
Excellent Conductivity: Copper is the benchmark for electrical and thermal conductivity. This property is indispensable for electrical connectors, terminals, heat exchangers, and radiators. CNC machining ensures the tight tolerances and complex geometries required for these critical components.

Antimicrobial Properties: Certain copper alloys possess inherent antimicrobial properties, a feature increasingly valuable in medical devices, healthcare hardware, and food processing equipment.

Applications Across Industries



The versatility of CNCmachined brass and copper parts is evident in their widespread use:

Electronics & Electrical: Connectors, terminals, sockets, and RFI/EMI shielding components.
Plumbing & Fluid Power: Valves, fittings, nozzles, and pump components that require corrosion resistance and pressure integrity.
Marine & Automotive: Bushings, bearings, decorative trim, and heat exchanger parts.
Consumer Goods: Precision parts for locks, musical instruments, and highend architectural hardware.
