Invar 42(Fe-Ni)

Post Views: 34 1. Introduce – Ni-Fe alloy with 42% Ni content – Low thermal expansion alloy with a low and consistent coefficient of thermal expansion, approximately one-tenth that of carbon steel, in the range of -20 to 300°C→ Invar 42 Coefficient of Thermal Expansion (CTE) : close to zero→ Has a coefficient of thermal expansion consistent with glass compounds and ceramic materials→ Used for glass-to-metal or ceramic-to-metal bonding applications – Invar 42 has a coefficient of thermal expansion of approximately 1.1 × 10^-6 /°C, lower than Invar (1.2 × 10^-6 /°C) and most ot...
