TOOL INDUSTRY

TOOL INDUSTRY

The brazing quality of cemented carbide inserts as well as the diamond sections to a large extent is decisive when it comes to the quality of a given tool. The correct brazing method as well as alloy and flux have to be selected. The alloy is selected on the basis of the material from which the insert is made. In order to look after the joint quality particular attention should be paid to the process of annealing of the brazed joint.

Alloys for the machine and tooling industry are available as rods, tapes and tapes with copper transfer.
