C92600 Tin Bronze Casting
C92600 Tin Bronze Casting (UNS C92600) contains nominally 87% copper, 10% tin, 1% lead, and 2% zinc. It delivers higher strength than standard gunmetal grades and excellent corrosion resistance in marine and industrial environments. Indicative price: US$ 9.50/kilogram (subject to quantity and specification).
