Invar 42ㅣUNS K94100

1. Introduce – A Ni-Fe alloy with a nickel content of approximately 42% – A low-thermal-expansion alloy that exhibits a thermal expansion coefficient of approximately one-tenth that of carbon steel at temperatures ranging from approximately 20 to 300°C – Used for bonding “glass-metal” or “ceramic-metal” joints because its thermal expansion coefficient is consistent with those of glass and ceramic materials – The coefficient of thermal expansion of Invar 42 is approximately 4.00~5.50 × 10⁻⁶/°C, which is lower than that of most other materials * In...
