car key The above picture for mass passat car keys. Our factory is engaged in manufacturing copper alloys in various shapes for over 10 years, including ordinary nickel copper alloys, high nickel copper alloys, free-cutting nickel copper alloys, ordinary brass, free-cutting brass, green copper available in the form of profiles and rods. Customized products in special shapes are also available as required. Our products are widely applied in such fields as auto parts, eyewear accessories, electronic components, crafts, watches & clocks, keys and so on. We are specialized in manufacturing nickel copper alloy profiles and all kinds of blanks for cars and keys. Features: 1. Being made of free-cutting nickel copper alloy profiles and having advantages of clean edges, no burrs, good cutting quality and high precision. 2. The state-of-the-art techniques: improved stamping, as well as automatic cutting and cleaning 3. Independently-developed nickel copper alloys and brass with free-cutting lead content (non hot pressing) 4. With the cold-drawing technique, the density and other parameters of products are close to, even higher than those of ordinary nickel copper alloys. Test methods: Punching a hole through the key blanks made by our factory and the ones made from common ordinary nickel copper alloy profiles with a 3.0# twist drill. Cutting the nickel copper alloys made by our factory into loose or cut-shot form with little continuity, while cut shots made from ordinary nickel copper alloy form continuous long strips. In comparison, the free-cutting nickel copper alloys made by our factory have advantages of less abrasion to cutter, little burr and easy processing. Inquiries are welcomed!
