composite metal blade, composite metal blade production methods and heat exchanger production methods, use of metal composite blades, and heat exchanger.

摘要

It is a material that includes a melt-cast aluminum alloy veneer to a metal alloy core. Also disclosed is a material that has a metal core with a high scrap metal content and has two sides, a first melt-cast aluminum metal veneer to the first side of the main layer, and a second cast aluminum metal veneer. by melting to the second side of the main layer. The materials may be in the form of a blade. Blades are laminated welded together to create permanent metallurgical bonds, except in regions where a weld break paint is applied. Blades are used to produce corrosion resistant heat exchangers.
