Coppery Weldable Pure Bare Copper Wire for Metal Oxide Film Resistors

Product Description

Product Description Bare Copper Wires:
Pure copper is formed by upward casting or horizontal continuous casting and rolling after the cathode copper is melted. The copper content is greater than 99.90%, and through further smelting, the purity of copper can reach 99.9999%. Adding a small amount of alloying elements can be melted into special copper alloys (silver copper alloy, magnesium copper alloy, tin copper alloy, nickel copper contract, etc.). Pure copper has good conductivity, thermal conductivity, and weldability, and is widely used in various fields such as aerospace, high-speed rail vehicles, household appliances, mechanical equipment, communication transmission, various cables, electronic devices, and so on.
Product Advantage:
1. Excellent conductivity, ductility, and thermal conductivity, with a wide range of application scenarios.
2. With excellent welding performance, it can meet the requirements of plasma welding, electron beam welding, laser welding and high-frequency welding.
3. Excellent softness, ideal material for automotive wiring harnesses and drag chain wiring harnesses.
4. The mechanical performance can be customized privately, ensuring stable and reliable application under different conditions.
