C1220 copper alloy is a kind of phosphorus deoxidized copper with copper (Cu) content ≥99.9%, containing trace phosphorus (P) about 0.015-0.04%. Its excellent electrical conductivity, thermal conductivity and processing performance make it the core material in the field of electrical and electronic.
I. Material properties
Ultra-high electrical and thermal conductivity: electrical conductivity of 98% IACS above, thermal conductivity ≥ 380W / (m-K), close to the performance of pure copper.
Excellent processing performance: phosphorus elements to improve thermal embrittlement, excellent hot and cold processing performance, can be drawn into very fine wire or stamping complex parts.
Corrosion resistance and weldability: strong surface oxidation resistance, tin welding, silver welding process adaptability.
Typical applications
Electrical industry: cable conductors, transformer windings, relay terminals and other highly conductive devices.
Electronic components: PCB circuit board jumpers, connector pins and other precision conductive parts.
Construction and heat exchange: roof waterproofing membrane, heat exchanger tube plate and other scenes with both thermal conductivity and weathering needs.
This material balances performance by controlling phosphorus content, and is a basic industrial material that balances economy and functionality.
