welding-alloys.com 6 Cobalt based alloys Cobalt based cored wires are mainly alloyed with carbon, chromium and tungsten. However, sometimes they are alloyed with nickel and molybdenum. These alloys are ideal for resisting wear caused by metalto-metal friction and abrasion at high temperatures, as they retain high hardness over time. Chromium provides a protective layer, playing an anti-oxidation role. Chromium, tungsten and molybdenum combined with carbon create hard carbides. Advanced laser wires All of our cobalt based alloy wires, including grades 1, 6, 12, 21, 25 and 188, have been developed for use in laser welding. These materials have a low coefficient of friction and a self-polishing tendency, making them highly resistant to scratching while maintaining excellent surface quality. Laser cladding is a well-suited process for applying these high-performance alloys, as it allows for a precise deposition of the exact amount of material needed to the specified working area.
