Tanaka Precious Metals expands lineup of electron beam welding materials

ntttttttttttt

Tanaka Holdings Co Ltd said Tuesday that Tanaka Kikinzoku Kogyo KK, which operates the Tanaka Precious Metals’ manufacturing business, has expanded its product lineup of electron beam welding materials used in sliding contacts on various automotive sensors.

The seven new types of electron beam welding materials each combine five precious metals (contact metals) and two copper-based materials (base metals) according to the application, expanding the lineup from one product to a total of eight.

Electron beam materials are highly reliable cladding materials (contact materials) able to function by combining metals with different properties when precisely welding the base metal and the contact metal together by using an electron beam as the heat source. In particular, it is most effective using the minimum amount of precious metal required in the manufacture of cladding material in functional shapes such as edge-lay and through-lay because it is possible to perform precision welding with material that has a higher purity than in arc welding (welding using radiated heat) which is currently the mainstream method.
