Copper Magnesium Alloy Wire (CuMg)
Magnesium content ranging from 0.10% to 0.4%
Copper Alloy Conductor
Copper magnesium alloy wire combines high strength with excellent resistance to bending, providing an ideal solution for various demanding applications. We produce this alloy with magnesium content ranging from 0.10% to 0.4% using a refined smelting process. Afterward, the alloy undergoes drawing, annealing, electroplating, and stranding to meet the required specifications. Available in single wire, stranded wire, multi-strand ropes, and parallel multi-wire configurations, the wire diameter typically ranges from 0.03mm to 8.0mm.
