The special environment-corrosive nature of water and slatwater, dictates the use of special material for shipbuilding.Even the pure aluminum has a high natural resistance to corrosion compared to many other metals, the constant exposure to water and moisture in marine application warrants additional protection.The marine-grade aluminum is specifically developed to make it ideal for use in marine environment.And marine-grade aluminum is with character of low density, high strength, high rigidity which is made of ships can achieve higher speed and longer service life.
