Nickel Based Alloy
Nickel-based alloys are materials composed primarily of nickel and other alloys. Nickel-based alloys are known for their excellent corrosion resistance and strength. Due to their excellent heat resistance, they are often found in high-temperature environments.
Description
Nickel-based alloys are also referred to as ni-based superalloys due to their outstanding strength, heat resistance and corrosion resistance. The face-centered crystal structure is a distinctive feature of ni-based alloys, since nickel operates as a stabilizer for the austenite.
Common additional chemical elements to nickel-based alloys are chromium, cobalt, molybdenum, iron and tungsten.
Products Description
Nickel alloys are usually made from a mixture of various metals and nickel. Not all metals combine effectively with nickel, though. Some of the most common elements that can be alloyed with nickel include iron (Fe), chromium (Cr), aluminium (Al), molybdenum (Mo), copper (Cu), cobalt (Co) and titanium (Ti). These elements can be combined to produce alloys with different properties. For example, alloys of nickel, iron, molybdenum and chromium, such as Type 316 stainless steel, have excellent corrosion resistance.
