Nautical brass
Alloy of copper and zinc, tin, seawater erosion resistance, can be used to manufacture parts, ship balancer.
bronze

Used for the manufacture of precision bearings, high pressure bearings, the ship's anti seawater corrosion of mechanical parts and a variety of sheet, pipe, bar, etc.. There is a bronze anomalous characteristics -- "thermal cold expansion", used to cast the statue, after cooling expansion, can make clear more clearly.
