ABSTRACT:
A cubic boron nitride compact is bonded to a cemented carbide support through an alloy bonding layer which contains 40 to 70 percent by weight silver, gold or a combination thereof and 1 to 10 percent by weight of a high melting metal selected from the group of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium and molybdenum. Bonding may be achieved by first metallizing a surface of the cubic boron nitride compact with a layer of gold or silver or a gold or silver based alloy and then bonding the metallized layer to the carbide support by means of a braze alloy having a liquidus temperature above 700.degree. C.
