70% of the ship's upper deck can be made of aluminum
Aluminum is a good material for superstructure and structure of cruise ships. Superstructure and facilities include: guardrail, partition wall, floor (with decorative decorative slide), ladder, furniture, living supplies, kitchen appliances, fire doors and so on.
Aluminum is a good material for superstructure and structure of cruise ships. Superstructure and facilities include: guardrail, partition wall, floor (with decorative decorative slide), ladder, furniture, living supplies, kitchen appliances, fire doors and so on. The use of aluminum alloy material to manufacture cruise ship superstructure has the following advantages: under the same performance conditions, aluminum structure and workpiece is about 40% ~ 45% lighter than steel; Clean health, bright color, in the service period does not need maintenance, unlike steel structure, every three or five years must be large maintenance, otherwise it will rust, not only ugly, but also may cause small accidents or unpleasant things; The biggest feature of aluminum is that although it is not a direct fireproof material, it is beneficial to fire prevention, because when on fire aluminum will absorb a lot of heat, melt quietly, help reduce the fire, and unlike magnesium, once in the open fire, there will be scary fierce combustion, so it is not suitable to use magnesium to manufacture cruise superstructure and facilities; After the cruise ship is scrapped, all the aluminum structure can be recovered, with a maximum of 5% mechanical loss. The recycling price of waste material is equivalent to 80% of the original aluminum ingot price at that time. Aluminum has strong corrosion resistance to water, whether fresh or seawater, so it is a natural superior material for cruise ship manufacturing; And the price of aluminum is reasonable and moderate, is competitive.
