ABSTRACT:
A ferro-sintered alloy having wear-resistance at elevated temperatures, comprises a perlite matrix having a copper content of from 0.2 to 1.5% by weight. 10 to 50% by weight of a phase A rich in heat and corrosion resistance is dispersed in the matrix with phase A including 9 to 20% Cr, 6 to 15% Ni, 1.5 to 9.5% Mo, 1.5 to 9.5% W, 0.7 to 4.5 Cu and an Fe remainder. In addition, 2 to 15% by weight of an additional component is dispersed in the matrix which is selected from one of a group of components which are wear-resistant. The group of components comprises:
