Product Overview​

Tinned copper wire integrates copper’s high electrical conductivity with tin’s solderability and corrosion resistance. The pure copper core ensures efficient current transmission, while the tin plating enhances solderability and protects against oxidation. It is widely used in electronics (circuit boards, connectors), electrical wiring, and automotive harnesses.​

Standard Designations​

• Material Standards:​

• Copper: Complies with ASTM B3 (electrolytic tough – pitch copper).​

• Tin plating: Follows ASTM B545 (electrodeposited tin coatings).​

• Electrical conductors: Meets IEC 60228 standards.​

Key Features​

• High conductivity: Enables low – loss current transmission.​

• Excellent solderability: Tin plating facilitates reliable soldering connections.​

• Corrosion resistance: Protects copper core from oxidation and moisture damage.​

• Good ductility: Allows easy bending and processing without breaking.​

• Temperature stability: Performs stably in – 40°C to 105°C environment.​
