How hard is invar
Like other nickel/iron compositions, Invar is a solid solution; that is, it is a single-phase alloy. In one commercial version it consists of approximately 36% nickel and 64% iron. The invar range was described by Westinghouse scientists in 1961 as "30–45 atom per cent nickel". Common grades of Invar have a coefficient of thermal expansion (denoted α, and measured between 20 °C and 100 °C) of about 1.2 × 10 K (1.2 ppm/°C), while ordinary steels have values o… Web25 jul. 2024 · 57K views 5 years ago To make invar ingots you will need 2 iron ingots, 1 nickel ingot and a pulverizer.
