Copper-magnesium results in a cold workable solid solution strengthened alloy with a high strength and nominal reduction in conductivity relative to copper ETP. CuMg is environmentally friendly alloy and have been specifically designed to be free of heavy metal elements such as cadmium, mercury and lead. CuMg combines high electrical conductivity with good tensile strength, excellent solderability and plateability. We can offer the CuMg in two variants: CuMg0,2 and CuMg0,5 with a higher resistibility and higher tensile strength. Lamifil can offer this alloy with a maximum of 5 ppm Oxygen.
