Low density, nonmagnetic and corrosion resistant cemented carbides

摘要

A resilient and corrosion and wear resistant component of tooling preferably used in the deep-drawing of aluminum and steel cans is disclosed. The tooling is comprised of a distinctive nickel-bonded cemented carbide having a density less than 13 grams per cubic centimeter, a hardness of at least 88 Ra, a minimum transverse rupture strength of 250,000 p.s.i. and exhibiting essentially non-magnetic behavior. Preferred compositions for the material of the tooling are also given.
