ISO14001 Certified Hard Drawn Round Phosphor Bronze Switch Wire

Product Description

Product Description Tin Copper Alloy Wire/Phosphor Bronze Wire:
Phosphor bronze is mainly composed of copper, containing 3.5~9% tin and 0.01~0.4% phosphorus. Mainly used in industry as wear-resistant parts and elastic components. It has good conductivity; Not prone to fever; Has strong fatigue resistance, higher corrosion resistance, stronger wear resistance, and no spark during impact; With excellent mechanical processing performance and chip forming performance, it can quickly shorten the processing time of parts, etc
Product Advantage:
1. Stable Performance: Tin-copper alloy wire has a high operating temperature range for harsh environment applications.
2. Good Mechanical Properties: High hardness, high strength and high toughness, withstand large forces and vibrations.
3. Durable and Good Corrosion Resistance: Withstand oxidation, sulfide and other corrosive media for a long time.
4. The mechanical properties can be privately customized, to ensure stable and reliable application in the different conditions.
