Snper-Invar Low Expansion Alloy TUBE
Snper-Invar is also called the Super - Invar alloy.In 60 ~ 80 temperature range, low expansion coefficient, the alloy is mainly used in the manufacture of requirements in the environmental temperature change range size high precision instrument parts.
Application and special requirements
Snper-Invar alloy is typical of low expansion alloy, via air factory use for a long time, stable performance.Mainly used in the manufacture of highly accurate within the scope of environmental temperature change size precision components.In use should be strictly controlled heat treatment process and processing technology, according to the using temperature must be strictly check the organization stability.
Chemical Composition in %, Invar
Basic physical constants and mechanical properties of the alloy:
Density: γ = 8,1 g / cm3;
Electric resistivity: ρ = 0,77 ohm mm2 ? / m;
The temperature of the Curie point: Θs = 220 ° C;
All offered "Shanghai Tankii Alloy Material Co., Ltd" of rolled metal products Invar differs guaranteed high quality. Customers can buy Invar alloy for the production of different types of products and rely on the high-speed supply of rolled metal.
