Copper-based alloys containing up to 14% aluminum form Aluminum Bronze . Aluminum Bronzes have different mechanical and chemical properties from other alloys. This type of bronze is preferred in casting parts. Cast bronzes contain tin, lead, phosphorus and nickel. Bronze material is highly resistant to environments such as corrosion, sea water and acid. It is one of the indispensable products of the valve pump and shipbuilding industry.
