摘要：
The invention relates to electric contact materials for use in switches, such as moulded circuit breakers, air circuit breakers, magnetic switches, etc.The electric contact materials comprise 5-60 weight % iron group metals, 1-11 weight % graphite, 5-70 weight % refractory materials, and the residual part consisting of silver, said refractory materials being held in the state of dispersion in the iron group metals and/or silver, thereby providing welding resistance, wear resistance, and insulation resistance as well as high practical utility of low temperature rise.
