Naval Brass, C46400, C47000 CW719R, C4641, :: Rajhans Metals

Naval brass is the classic marine, highstrength and corrosionresistant alloy containing 60 percent copper, .75 percent tin and 39.2 percent zinc. The addition of Tin also gives Naval Brass a high resistance to dezincification. It is widely used in marine construction where strong, corrosiveresistant and hard material is required and is suitable for both salt and fresh water applications.

The lead free naval brass is the result of the composition of 60 copper, 39.2 zinc and 0.8 tin. The addition of tin with zinc results in the high corrosion resistance in sea water. This makes the alloy resistant to dezincification that inhibit the impingement by seawater at higher than normal temperatures.
