Welding Naval Brass. Inhibited 44300 Admiralty Brass has. These may be alloyed with tin generally described as phosphor bronze silicon or aluminium.
Welding using the manual metal arc MMA process is not recommended for naval brass or any other zinc-bearing copper alloy. The addition of tin is made for extra corrosion resistance in seawater and other mildly aggressive environments. Naval Brass is a 6040 copper zinc alloy to which about 1 of tin has been added to improve the corrosion resistance particularly to dezincification.
The alloys most commonly welded are aluminum brass 76 copper 22 zinc 2 aluminum Admiralty brass 70 copper 29 zinc 1 tin and Naval brass 62 copper 3675 zinc 125 tin.
The addition of tin is made for extra corrosion resistance in seawater and other mildly aggressive environments. Similar in appearance to naval brass and its welding processes bronze casting alloys are another option. Naval brass is used in propeller shafts marine hardware decorative fittings shafting propeller shafts and turn buckles. Flux Proper fluxing is essential in braze welding.
