Brass CNC Machining

Brass is a copper-zinc alloy known for its excellent electrical conductivity, low friction properties, and gold-like appearance. It finds diverse applications in architecture, gears, locks, musical instruments, and more. Brass alloys vary based on zinc and other elements like lead, aluminum, and iron. With its copper content, brass is thermally and electrically conductive and offers good wear resistance. Lead inclusion enhances machinability, making brass the most machinable copper alloy. CNC machining brass yields mechanically strong, low-friction components with improved corrosion and wear resistance, making it ideal for mechanical applications, including those in the marine industry.

Brass CNC machining refers to the process of using Computer Numerical Control machines to manufacture precision brass components and parts. Brass CNC machining is commonly used in industries such as automotive, aerospace, electronics, plumbing, medical devices, and more, where precision and quality are crucial. It enables manufacturers to create high-quality brass parts that meet strict specifications and perform optimally in their intended applications.

Finishes and Post-Processing Options

As machined (standard): Brass is readily machined, so its freshly machined surface will often exhibit an attractive finish even without any extra attention. Therefore, it is often possible to leave the part in a machined state. Surface finish is further improved with additional finishing passes.

Polishing: Polishing is a popular finish for brass, as it brings out the lustrous shine of the metal. It can range from a bright mirror-like finish to a satin or brushed finish, depending on the level of abrasion used.

Sandblasting: Sandblasting brass involves using fine abrasive particles to etch the surface, creating a matte finish or adding texture for a distinctive appearance.
