Processing
(1) Prepare 60% palladium and 40% silver according to the mass percentage, and add trace rare earth elements if necessary to improve performance.
(2) Vacuum induction melting or arc melting and mixing, and the melt is refined and cast into flat ingots.
(3) Hot rolling and cold rolling are alternated to reduce the thickness and control the flatness and accuracy.
(4) The electrical contact material needs to be treated with a solution and aging to improve strength and conductivity
(5) Finishing process and surface treatment to achieve the dimensional accuracy and surface roughness required by customers.
(6) Quality testing, such as hydrogen penetration flux test, conductivity measurement, visual inspection, non-destructive testing, etc.
