Cobalt-based alloys usually are described as wear-resistant, corrosion-resistant and heat-resistant alloys. Many of the alloy's properties arise from the crystallographic properties of cobalt (especially its response to stress), the solid solution strengthening effects of chromium, tungsten and molybdenum, the formation of metal carbides, and the corrosion resistance imparted by cobalt to chromium. Typically, softer and harder compositions are used for high-temperature applications, such as gas turbine blades and strips. Harder grades are used to resist wear.
alloy L605, also called Haynes 25, UNS R30605, has given good service in many jet engine parts and gas turbine engine components.
Cobalt Alloy is supper alloys resistant to various types of wear and corrosion as well as high temperature oxidation.
ERCoCr welding rod bonds well with stainless and other weldable alloy steels. Certification to AWS specification – A5.21 ERCoCr-A for bare rod; A5.13 ECoCr-A for the coated electrode.
Cobalt alloy extrusion dies can increase the service life of extrusion dies and improving production efficiency.
