CAC402 Bronze Casting
CAC402 Bronze Casting is a tin bronze specified under JIS H 5111 CAC402 (formerly BC2), containing nominally 90% copper and 10% tin. The Japanese Industrial Standard equivalent of the European CuSn10 and the British PB1 phosphor bronze, CAC402 is used for high-hardness gears, worm wheels, and precision bearings in Japanese and global industrial equipment. Indicative price: US$ 10.00/kilogram.
