Abstract
Electrical contacts and welding electrodes are made from an alloy containing by weight W 32 to 36%, Mo 32 to 36%, Cu and impurities balance. In one example described the raw materials are 41% by weight each of Mo and W powders not over 5 microns in Fisher average particle size, and 18% by weight of Cu powder of minus 100 mesh. These are blended by ball milling, a binder added, and compacts of desired shape obtained by conventional pressing techniques. The compacts are then sintered at 1300-1350 DEG C. for 6-20 minutes in an inert or reducing atmosphere, followed by infiltration of the balance of the Cu at 1200-1275 DEG C. In a second example, the correct amounts of W, Mo and Cu to yield the desired composition are blended and fritted at 1100-1200 DEG C. into slightly sintered cakes which are then broken up, screened and the powder pressed and sintered in the range 1350-1425 DEG C. for not less than 30 minutes.
