Knowledge of Nickel Base Alloys

Nickel base alloy is a kind of alloy with nickel as the matrix (the content is generally more than 50%), which can maintain high strength, good oxidation resistance and gas corrosion resistance under high temperature in the range of 650~1000 ℃.

Wear-Aesistant Alloy

The main alloy elements are chromium, molybdenum, tungsten, and a small amount of niobium, tantalum and indium.

Heat-Resisting Alloy

The main alloy elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium, etc. Among them, Cr, Ai and other elements mainly play the role of oxidation resistance, while other elements have the role of solid solution strengthening, precipitation strengthening and grain boundary strengthening.
