Copper Alloy Conductor

Copper Magnesium Alloy Wire (CuMg)

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.

Wire Drawing Range

0.2351mm→0.0805mm (13 drawing dies)
0.641mm→0.164mm (19 drawing dies)
0.4610mm→0.127mm (20 drawing dies)

Features

Compared to traditional copper wire, copper magnesium alloy wire offers superior strength and enhanced flexibility. Although the alloy has slightly higher resistance, the impact on signal transmission is minimal, ensuring reliability in applications that require durability and flexibility.

Wire Spools & Packaging

We provide wire spools in three different types: plastic, wood, and metal. Each option is designed to cater to specific customer preferences and ensure efficient handling and storage.
Standard packaging options include cardboard boxes, foam boxes, wooden crates, and wooden pallets, ensuring safe transport and handling.
Wooden packaging such as crates and pallets are made from fumigated solid wood or non-fumigated plywood. Custom packaging solutions are available based on customer requirements.
