Abstract
A heat-resistant sintered hard alloy comprises 35% to 95% by weight of a WCoB type complex boride in a cobalt base alloy. The alloy contains 1.5% to 4.1% boron, 19.1% to 69.7% tungsten, optionally 1 to 25% chromium, the balance being cobalt and a maximum of 1% impurities. Nickel, iron and/or copper may be substituted for portions of the cobalt content.
