BIMETAL WORKPIECES

Double-layered bimetal sheets

Possibility of bonding of any commercially available metals and alloys.

Parent sheets shall have at least 25% elongation to avoid cracking. Bonding with elongation of less than 25% and without cracking is possible, but in each such case a specific solution is required.

In particular, the explosion welding department has manufactured products with the following combinations of metals:

Primary layer	Cladding layer
Carbon steel	+carbon steel;+stainless steel; +titanium; +brass; +copper; +aluminium; +nickel; +monel; +melchior; +tantalum; +niobium; +cobalt
Stainless steel	+aluminium; +titanium
