Up to 80 % - lower CTE than INVAR 36.
Discovered many years later than INVAR, SUPERINVAR has an - up to 80 % - lower CTE than INVAR 36. PHYNICX has developed an optimal analysis of this alloy and the required annealing treatments to avoid creep and phase transformation, relatively often occurring after hot or cold forming.
The chemical composition of this alloy is:
|Nickel (Ni): 32%|
|Cobalt (Co): 5%|
|Iron (Fe): Balance|
The expansion coefficient is:
