Abstract
PURPOSE: To provide an electric contact material having a smll contact resistance, excellent workability and deposition resistance by a method wherein specific amount of Ni powder and Cr powder is mixed with Ag powder and the mixture is sintered.
CONSTITUTION: To Ag powder of less then 200mesh, 0.05W15wt% of carbonyl Ni powder of less than 250mesh and 0.05W10wt% or Cr powder are added and mixed for 20hr. The mixture is formed under a pressure of 5 ton/cm2 and is sintered under a reducing or non-oxidizable atmosphere at 850°C for 1hr. The sintered body is hot rolled to a 1mm thick hoop to provide an electric contact material used as breaker contact, etc. The obtained material is excellent is deposition resistance and workability and has a small contact resistance and arc persisting time.
