Overview of Iron Nickel Alloy Powder
Iron-nickel alloy is an alloy material mainly composed of iron and nickel and usually also contains small amounts of other metal elements, such as cobalt, copper, silver, etc. This alloy has excellent corrosion resistance, high-temperature strength, and good magnetic properties, so it is widely used in aviation, chemical industry, electronics, medical, and other fields.
Iron Nickel Alloy Powder, Nickel Iron Alloy, Alloy Iron and Nickel
The nickel content in iron-nickel alloys is usually higher, generally above 30%, which gives it better corrosion resistance and high-temperature performance than ordinary steel. In addition, iron-nickel alloys also exhibit good plasticity, toughness, and weldability.
It is worth mentioning that iron-nickel alloy is a magnetic material with a relatively low frequency. Still, in a weak magnetic environment, its probability of magnetic conduction is very high, and it has the characteristics of not being easily deformed. This made iron-nickel alloy mainly used in the field of communications in the early days. With the development of science and technology, its properties have been further improved and its application areas have also expanded.
