Atmospheric and Marine Corrosion Resistant Electrical Copper Magnesium Alloy Wire for Aerospace

Product Description

Product Description

Copper Magnesium Alloy Wire:
Copper magnesium is available as round solid wire, the chemical composition of copper magnesium alloy wire typically contains a combination of copper (Cu) and magnesium (Mg) as the main elements. The specific composition may vary depending on the desired properties and application of the alloy. Magnesium increases the strength of the copper and reduces the conductivity relatively slightly. By adding Mg in the range of 0.1 to 0.8 % Mg, the ratio of tensile strength and conductivity can be adjusted very precisely.

Copper magnesium alloy wires are widely used in industries such as industrial robots, communication signal transmission, medical equipment, high-speed railways, and automobiles.

Product Advantage:
1. High strength, light specific gravity, good tensile strength and good solderability.
2. The resistance to atmospheric and marine corrosion is good.
3. High Electrical Conductivity:
√ CuMg0.2: ≥78% IACS
√ CuMg0.5: ≥62% IACS
