Invar 36 Alloy: The Ultimate Guide to the Low-Expansion Supermetal
1. Material Overview: Why Invar 36 is a Modern Engineering Cornerstone Invar 36, a iron-nickel alloy renowned for its ultra-low thermal expansion, is a critical material in fields where dimensional stability under temperature fluctuations is non-negotiable-1. Its core value lies in an exceptionally low Coefficient of Thermal Expansion (CTE), typically around 1.2 x 10⁻⁶/°C between -250°C and +200°C-2. This […]
