C19700 | CuFe0,7MgP

The microstructure is formed in a single phase by light microscopy and is very fine-grained due to the strong deformation. The hardness is 123 HV 0.05.

It is a precipitation hardenable alloy. It combines high electrical conductivity with high strength and good relaxation levels, comparable to CuFe2P (CW107C | C19400). This is achieved by a reduced iron content and the addition of magnesium. The alloy has good formability and corrosion resistance and is suitable for brazing and welding. Areas of application are the automotive industry, connectors, spring contacts and carrier strips.
