Cooper Rolled Products

With more than 20 high-performance precision copper alloys for rolled strip in our portfolio, we are able to supply the global copper processing industry with customized solutions. These include Boway’s self-developed copper-nickel-tin alloy, copper-nickel-phosphorus alloy, copper-nickel-silicon-cobalt alloy, copper-tin-phosphorus alloy, and tin-phosphorus-zinc-copper alloy.

These copper alloy strip series have excellent physical, mechanical and bending properties as well as thermal stress relaxation performances, high temperature softening and anti-fatigue properties. Additionally, thanks to our advanced technological equipment, we can assure different surface finishing qualities and a very tight control of the specified tolerances. They are widely used in fields such as automotive electronics, 5G communications, consumer electronics and lead frame. With professional application support capabilities, Cooper Rolled Products provide comprehensive application solutions to continuously create value for global customers.
