CC490K Bronze Casting
CC490K Bronze Casting is a tin bronze specified under EN 1982 CC490K (CuSn10), equivalent to DIN 2.1050. It contains nominally 90% copper and 10% tin with no lead or zinc additions, offering high hardness, excellent wear resistance, and strong corrosion resistance for demanding gear and bearing applications. Indicative price: US$ 10.00/kilogram.
