Copper alloy wire (including speaker wire core wire, copper plated wire, etc.)

Copper alloy wire is a high-performance metal wire made with copper as the base and formed by adding alloying elements such as zinc, tin, nickel, chromium, and zirconium. Its properties combine the excellent electrical conductivity and thermal conductivity of copper with the strengthening characteristics of the alloying elements, and it is widely used in the fields of electronics, new energy, automobiles, aerospace, etc.

Material Diversity:

Brass (Cu-Zn): With high hardness and corrosion resistance, it is suitable for connectors and springs.

Bronze (Cu-Sn): With high elasticity and wear resistance, it is used for precision instruments and strings of musical instruments.

Cupronickel (Cu-Ni): Resistant to seawater corrosion, it is widely applied in marine engineering.

Chromium-zirconium copper (Cu-Cr-Zr): With high strength and high electrical conductivity, it is used in 5G base stations and flat wire motors of new energy vehicles.

Rare earth modified oxygen-free copper: It is a domestically innovative technology with low resistance and high purity, and has obtained the new material certification of the autonomous region for three consecutive years.

Performance Advantages

Electrical Performance: The electrical conductivity reaches over 55% IACS, and the signal transmission loss is lower than - 0.5dB/m (10GHz), meeting the high-frequency requirements of 800G optical modules.

Mechanical Performance: The tensile strength ranges from 200 to 1200MPa, the elongation is between 5% and 30%, the number of bending resistance is more than 100,000 times, and it can adapt to complex wiring environments.

Environmental Adaptability: Passed the salt spray test (> 500 hours) and high-temperature aging test (200°C × 1000 hours), and its stress relaxation resistance performance is 20% better than the industry average level.
