Cu10Ni49Sn41
metal· Cu10Ni49Sn41
Cu10Ni49Sn41 is a copper-nickel-tin ternary alloy that belongs to the cupronickel family, a class of brasses and bronzes valued for corrosion resistance and strength. This composition—approximately 10% copper, 49% nickel, and 41% tin by mass—is typically encountered in specialized marine and electronics applications where resistance to seawater corrosion and thermal cycling is critical. The high nickel and tin content provides enhanced durability in aggressive aqueous environments and improved fatigue performance compared to binary copper-tin or copper-nickel systems.
