Argentel™ Filler Metals
The Argentel™ range of products are designed for the brazing of steel or copper components and also for brazing steel to tungsten carbide in tooling applications. Additions of tin, silicon and manganese allow control of fillet, flow, penetration and surface appearance.
Argentel™ is often used for bronze welding.

Argentel™ is a braze/bronze welding alloy that contains nickel, which makes the alloy stronger and harder but less fluid when molten than a standard Cu-Zn filler metal such as Argentel™ No.1 or Argentel™ 303.

This filler metal is more fluid than Argentel™ when molten. It is not as strong or hard and is more suited to applications, which are of the true brazing nature such as joints on cycle frames and in steel furniture.
