Description

The palladium-copper material PdCu40, also known as Pd60Cu40 or 60Pd40Cu, is ductile, erosion-resistant and abrasion-resistant. It can be machined with or without cutting, is roll-cladable, can be limited separated from the gas phase. On the one hand, PdCu-based alloys are more resistant to erosion than PdAg and, on the other hand, show a considerably lower tendency for material migration. They are therefore particularly suitable for contact materials in DC circuits and are usually used with 15% or 40% Cu admixture. PdCu15 forms homogeneous mixed crystals, while PdCu40 achieves an ordered microstructure by heat treatment below 600 ° C, which significantly reduces the specific electrical resistance and almost completely eliminates the tendency for material migration. PdCu40 is used as a contact material in flasher relays of motor vehicles and in the higher switching power range and as a monolithic contact spring material. The PdCu40 has a slight increase in hardness due to copper (Cu). Palladium and copper are infinitely miscible.
