Product Description
High-Conductivity CuMg0.4/2.1322 High Temperature Alloy Wire for Electrical in Harsh Environments
CuMg0.4 (also known as 2.1322) is a copper-magnesium alloy wire known for its high strength, excellent conductivity, and corrosion resistance. With 0.4% magnesium content, it offers enhanced mechanical properties compared to pure copper while maintaining good electrical performance. Due to its combination of strength, conductivity, and corrosion resistance, CuMg0.4 alloy wire is a preferred choice in electrical, transportation, and industrial applications requiring reliable performance in demanding environments.
