Invar36 is a special iron-nickel alloy also known as 4J36. This grade is manufactured by the American company Invar Alloys Incnamed to highlight the special properties of the alloy. The composition of invar36 is mainly 36% nickel and 64% iron. It has a very low coefficient of thermal expansion and is almost unaffected by temperature changes, so it is widely used in fields that require dimensional stability.
Invar36 is characterized by an extremely low coefficient of thermal expansion, which means that its dimensions change very little when the temperature changes. This feature makes INVAR36 widely used in optical instruments, precision instruments and balance precision equipment. It is also used in the aerospace and chemical industries to make fuel and gas reservoirs, spacecraft and satellite components, among others.
In conclusion, Invar36 is an iron-nickel alloy with stable dimensional characteristics for applications that require high precision and stability.

The main components of invar36 are 36% nickel and 64% iron. Here are some of the physical properties of Invar36:
1. Coefficient of thermal expansion: Invar36 has a very low coefficient of thermal expansion, about 12×10^-6/℃。This means that it changes very little in size when the temperature changes.
2. Density: The density of invar36 is about 81 g cm, relatively tall.
3. Magnetism: Invar36 is a magnetic material with low permeability. It has a low magnetization and magnetic induction strength, so it can effectively reduce the interference of magnetic fields in some applications.
4. Electrical conductivity: Invar36 has high electrical conductivity, but it is not an excellent conductor.
5. Corrosion resistance: Invar36 has good corrosion resistance to most non-oxidizing acids and alkalis. However, under strong oxidizing acids and high temperatures, it can be subject to corrosion.
Overall, INVAR36 has stable dimensional characteristics, low coefficient of thermal expansion, and good corrosion resistance, making it ideal for many precision instruments and devices.
Invar36 Process Performance and Requirements:
1.Alloys are easily processed both cold and hot. Heating in a sulfur-containing atmosphere should be avoided during thermal processing.
2.The cutting characteristics of this alloy are similar to those of austenitic stainless steels. High-speed steel or cemented carbide tools are used for machining, and low-speed cutting is used. Coolant can be used during cutting. The alloy has good grinding properties.
