Formula: Cu 63/Zn 37
Form: Wire
Material: Copper/Zinc (Brass)
Commodity: Alloys
Temper:
Hard
Brass Spooled Wire (Cu63/Zn37) offers a combination of high tensile strength, excellent corrosion resistance, and superior machinability, making it ideal for continuous-feed manufacturing processes. The 63% copper and 37% zinc composition delivers both durability and electrical conductivity, enabling use in applications that require structural integrity alongside functional performance. This alloy is employed extensively in the electronics sector for connectors and terminals, in jewelry manufacturing for decorative yet durable designs, and in precision engineering for fine mechanical components. Specific uses include coil winding for electrical devices, intricate spring fabrication, and conductive braiding. In research, Cu63/Zn37 wire is evaluated for its electrochemical stability, forming behavior, and wear resistance, aiding in the development of advanced interconnects and high-reliability components. Its versatility, consistent quality, and adaptability to high-speed processing make it a mainstay in both industrial production and applied materials research.
