Invar36 alloy, also known as invar alloy, is a special low expansion iron nickel alloy with ultra-low expansion coefficient. Cold deformation can reduce the coefficient of thermal expansion, and heat treatment within a specific temperature range can stabilize the coefficient of thermal expansion. It has corrosion resistance in dry air at room temperature. Guoxin foil innovative process: (1) adopting rapid solidification + rapid cooling, the grain is refined to micron level, the tensile strength and elongation are increased by ~10%, and the product is better; (2) The process is shortened by 60%, the whole process is protected by gas, and the alkali pickling is avoided, so the process is more ecological.

Product specification: 0.01~0.35 × 200~600mm
