7075 marine aluminum plate, its corrosion resistance and oxidation resistance are good, it also has good easy processing , and Wear resistance and workability are also good, with high strength below 150 ° C, and particularly good Low temperature strength, poor welding performance, tendency to stress corrosion cracking, double-stage aging can improve SCC resistance.

6061 marine aluminum plate has excellent processing performance, excellent welding characteristics and electroplating properties, good corrosion resistance, toughness, easy to polish, color film, excellent oxidation effect.

5052 marine aluminum plate is AL-Mg alloy gold aluminum plate, which is the most widely used anti-rust aluminum. High strength, especially fatigue resistance: high plasticity and corrosion resistance, cannot be strengthened by heat treatment, Good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, Poor cutting performance, can be polished. 5052 aluminum plate is often used for sheet metal parts of transportation vehicles, ships, instruments, street, Lamp brackets and rivets, hardware products, electrical enclosures, etc.

5083 aluminum coils belongs to Al-Mg series alloy. It is the highest strength corrosion-resistant alloy among practical non-heat-treated alloys. And it is suitable for welding structures. Also, it is worth mentioning that 5083 aluminium sheet has good resistance to seawater and low-temperature characteristics. Therefore, 5083 aluminium sheet has become the most suitable choice for marine-grade aluminium.

The main alloying element in 5083 marine aluminum plate alloy is magnesium, which has good corrosion resistance and weldability and medium intensity. Excellent corrosion resistance enables alloy 5083 to be widely used in marine applications such as ships, and Automobiles, aircraft welding parts, subway light rails, pressure vessels that require strict fire protection (such as liquid tankers, refrigerated trucks), refrigerated containers), refrigeration units, TV towers, drilling equipment, transportation equipment, missile parts, Armor etc. Good strength, corrosion resistance and machinability in non-heat treatable alloys. Anodized table Beautiful face. Can be processed into optical mechanical parts. Ship parts and wire clips.

Among the alloy states of 5083 aluminium sheet plate, most are H111/H112/H116/H321. Among them, the magnesium content of 5083-h116 aluminum sheet is as high as 4.9%, which is a high-magnesium alloy. It has high corrosion resistance and can resist the erosion of seawater. It is mostly used for underwater parts of ships.

The density of 5083-h116 aluminum sheet is low, only 2.66 g/cm³; the tensile strength of 5083 alloy is higher, which is higher than some low-carbon mild steel, and it is durable and has excellent corrosion resistance; 5083 h116 aluminum sheet The welding performance is also very good, and it is not easy to crack and deform after processing.

5083-h116 and 5083-H321 aluminum plates have better corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112 temper. Although the temperature of 5083H116 and H321 aluminum sheets are slightly different in the production process, the corrosion resistance is significantly better than other tempers.

The use of 5083-h116 aluminum sheet for marine aluminum sheet depends on three factors

1. Consider light weight.

Marine aluminum plates generally use thin plates over 1.6mm and thicker 5083-h116 aluminum sheets over 30mm. Aluminum-magnesium alloys have low density and light weight, which can reduce the weight of the hull and increase the load capacity.

2. Consider from the aspect of corrosion resistance.

5083 h116 aluminum sheet belongs to the aluminum-magnesium alloy, which is a typical anti-rust aluminum, which can adapt to the highly corrosive seawater environment for a long time.

3. Consider from the aspect of safety.

5083-h116 aluminum sheet has medium strength, good processing performance, excellent weldability, fatigue resistance, no cracks, and can still meet the strength and corrosion resistance requirements after processing, which can ensure the safety of the ship

As a shipbuilding material, aluminum alloy has small specific gravity and elastic modulus, corrosion resistance, weldability, easy processing, non-magnetic and good low temperature performance.

1. Using aluminum alloy, the density of aluminum is low, the weight of the ship is reduced, the single engine capacity can be reduced, the speed can be increased; the fuel consumption can be reduced, and the oil can be saved; the aspect ratio of the ship can be improved, the stability can be increased, and the ship can be easily maneuvered. ; can also increase the load capacity for extra profit.

2. Good corrosion resistance, reduce maintenance costs such as oiling, and have a long trial period.

3. Good processing and forming performance, easy to carry out various forms of processing such as cutting, stamping, cold bending, forming and cutting, suitable for streamlining the hull; it can extrude large wide and thin-walled profiles, reduce the number of welds and make The hull structure is rationalized and lightweight.

4. Good welding performance, easier to weld.

5. The elastic modulus is small, the ability to absorb impact stress is large, and there is greater safety.

6. Aluminum scrap is easy to recycle and can be recycled.
