PdW10 Alloy Deformation: Key Properties & Applications

The palladium-tungsten alloy PdW10, also Pd90W10 or 90Pd10W, is used as contact material (tapping contacts) as well as potentiometer alloy. The material is ductile, corrosion-resistant and abrasion-resistant. It is machinable, conditionally deductible from the gas phase.
