WebInvar may be worked using any conventional working method. Annealed material, that is material with an RB hardness of less than Rockwell B 70, is desirable for material involving deep drawing, hydro-forming or spinning. For blanking, material between 1/4 and 3/4 hard will usually present a cleaner cut. Invar may be chemically etched.
