66-30-2-2 (C71640) Alloy Sheet Plate Strip
66-30-2-2 (C71640) has very high erosion and corrosion resistance. It has very high weld ability, easy for installation and high antifouling properties against sea microorganisms. Relatively high iron content provides better impingement attack resistance. The alloy is unique to stress corrosion cracking. This form of copper alloy gives the best service life under the most adverse conditions.
