摘要：A contact of a vacuum interrupter and a manufacturing process therefor aredisclosed. The contact can greatly reduce the chopping current of the interrupter, cangreatly increase the dielectric strength thereof and can improve the large- and small-current interrupting capabilities thereof. The contact is made of a material containing 29to 74 weight % copper, 15 to 60 weight % chromium, 10 to 35 weight % iron, 0. 5 to 15weight % carbon and 0.5 to 15 weight % silicon. The process contains the steps ofproducing a porous matrix by sintering a mixture of all of the elements except copperunder a nonoxidizing atmosphere, impregnating the matrix with copper and machiningthe resultant material.
