Abstract: In an electrical contact in which aggregation phases including Cu are dispersed in a matrix phase including Mo, Cr, and Cu, a maximum grain size of the aggregation phases falls in a range of 4 to 20 µm and, when the total Cu content in the electrical contact is denoted by W t , the Cu content in the matrix phase is expressed by C × W t , where C ranges from 0.54 to 0.81. A process for producing an electrical contact including Mo, Cr, and Cu includes a step of compacting mixed Mo and Cr powders, thus forming a powder-compression compact and a step of making the powder-compression compact infiltrated with molten Cu.
