C6782
(high power brass) | C6782 is said to be high power brass and is the brass which added manganese and aluminum, iron. I am superior in strength as the name of the high power shows it and am good for forging characteristics and corrosion resistance between the heat. It is used as a propeller axis and the pump axis for the ship, the water pressure cylinder parts. | Forging, ship between the heat, parts for the mine |
