TOOL COMPONENT

摘要

A tool component comprises an abrasive compact bonded to a support which itself is bonded through an alloy to an elongate cemented carbide pin. The alloy has a liquidus below 900.degree.C and the following composition, by weight: Mn 15 - 41% Cu 67 - 41% Ni 1 - 5% Au 10 - 17% The shear strength of the bond achieved between the support and the pin exceeds 345 MPa.
