BAl13-3 High-Strength Aluminum White Copper Standard GB/T 13808-1992

Supply of High-Strength Corrosion-Resistant BAl13-3 Aluminum White Copper Plate, Cold Resistance BAl13-3 Copper Strip Direct from Manufacturer

Standard: GB/T 13808-1992

Characteristics and Application Range

BAl13-3 aluminum white copper is a structural copper-nickel alloy that can be heat-treated. In addition to high strength (the highest among white coppers) and corrosion resistance, it also possesses high elasticity and cold resistance. Its mechanical properties not only do not decrease at low temperatures (90K) but actually improve, a characteristic not found in other copper alloys.
