  • Method of inductive bonding sintered compacts of heavy alloys
    Patent number: 5760378
    Abstract: A method of bonding two or more sintered compacts of tungsten heavy alloys. The method includes the steps of providing two or more sintered compacts of tungsten heavy alloy powder and then positioning the sintered compacts in adjacent alignment in a furnace chamber. A localized induction field is applied only at the juncture of the sintered compacts to bond the sintered compacts and produce a monolithic assembly of sintered compacts having a bond strength substantially equal to the strength of the sintered compacts.
