CNC machining materials--invar

- Apr 05, 2018-

Invar (invar, also known as the invar, national standard called expansion alloy), is a kind of nickel and iron that contains 36% of nickel and iron by 63.8%, and 0.2% carbon, its low thermal expansion coefficient, can be in wide temperature range fixed length.

Invar alloy at room temperature near the average thermal expansion coefficient below 10-6 ℃ - 1, mainly used for manufacturing gauge, thermometer, range finder, clock and watch escapement, gauge block, the resonant cavity of microwave equipment, gravimeter components, thermal bimetal component materials, optical instrument parts, etc.Molten manufacturing.
