摘要:
The present disclosure aims to provide an electrical contact to which a low boiling point metal is added, the electrical contact being able secure both mechanical strength and conductivity at the same time. The electrical contact according to the present disclosure includes a base material made of Cu, particles of a high melting point substance dispersed in the base material, the particles being made of at least one of a high melting point metal or a carbide of the high melting point metal, and Te and Ti dispersed in the base material, wherein, the Te of 3.5 to 14.5 mass % is added where the total is 100 mass %, and Ti/Te is 0.12 to 0.38.
