Abstract

PURPOSE: To enhance the hardly dissipative property and to stabilize the width of a voltage drop by adding prescribed amounts of Ni, graphite, Cr or Cr-Fe, and Ag and forming Cr3C2 on the graphite surface.
CONSTITUTION: This electrical contact material consists of, by weight, 5W 70% Ni, 0.5W7% graphite, 0.1W1% Cr or Cr-Fe, and the balance Ag. On the surfaces of the graphite particles Cr3C2 is formed by reacting part or all of the Cr with graphite. Thus, the hardly arc dissipative property is enhanced, and the width of a voltage drop is stabilized.
