Super-Nilvar Low Expansion Alloy rod
Super-Nilvar 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
Super-Nilvar 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.
