Recently, cobalt prices have fluctuated greatly, the prices of products in the market may also vary greatly. There will also be many not actually cobalt products or reducing cobalt content and reducing costs. Then to know the way how to test the materials and products is very important.

Cobalt alloy is a kind of metal material alloy, mainly composed of cobalt, chromium and tungsten elements. It has high hardness and good wear resistance. Even when the temperature reaches a red hot state, its performance is hardly affected.
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.
