Custom Brass Machined Parts
Contract Manufacturing for Brass
Brass is an ideal material for custom machining due to its excellent corrosion resistance, formability, and attractive appearance. Alloys such as Brass 220 and Brass 360 offer high strength and good machinability, making them perfect for intricate components in various applications, from plumbing fixtures to electrical connectors. With a rich range of compositions—from the malleable Brass 230, suitable for electrical uses, to the durable Brass 464, known for its resistance to corrosion—brass provides versatility that meets diverse manufacturing needs. By choosing brass for your custom parts, you benefit from not only superior performance but also enhanced aesthetic qualities, ensuring your components stand out in both functionality and design.
