Copper Tin Alloy Wire (CuSn)
Magnesium content ranging from 0.10% to 0.4%
Copper Alloy Conductor
We manufacture copper-tin alloy materials with varying tin content (Sn: 0.15%-6%) through a precise smelting process. These alloys are then processed through drawing, annealing, electroplating, and stranding to create products in different configurations, including single wire, stranded wire, multi-strand wire ropes, and parallel multi-wires. The wire diameter ranges from 0.02mm to 8.0mm, and the alloy maintains strong mechanical properties while offering flexibility for a variety of applications.

Copper-tin alloy wire offers increased strength and resistance to bending compared to traditional copper wire. Although copper alloys generally have slightly higher resistance, the impact on signal transmission is minimal, allowing for use in many applications.
