Product Description

CuMg0.4/2.1322 High Temperature Alloy Wire For High-Stress Applications

CuMg0.4 (2.1322) is a copper-magnesium alloy wire known for its high strength, good conductivity, and excellent corrosion resistance. With 0.4% magnesium, it offers improved mechanical properties while maintaining good electrical performance. CuMg0.4 (also known as 2.1322) is a Copper-Magnesium (Cu-Mg) alloy wire that combines the excellent electrical and thermal conductivity of copper with the strength and corrosion resistance of magnesium. It is primarily used in applications requiring high conductivity, lightweight properties, and mechanical strength.
