Copper Alloy Conductor

Copper Tin Alloy Wire (CuSn)

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.

Wire Drawing Range

0.2386mm→0.1224mm (10 drawing dies)
0.0391mm→0.0260mm (10 drawing dies)
0.2348mm→0.0862mm (16 drawing dies)

Features

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.

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.
