In recent years, with the rapid development of the shipbuilding industry at home and abroad, reducing the weight of the hull,increasing the speed of the ship, and seeking aluminum alloy materials to replace steel components have become important issues for the aluminum processing industry and the shipbuilding industry.
Alloy 6082 has medium strength and good corrosion resistance, and is light in weight, which is an ideal material for manufacturing high-speed boat components. What are ,6082 aluminum properties?
Its tensile strength≥310MPa, yield point≥250MPa, elongation≥10%. Due to the high performance requirements of this product, Mg, Si, Fe and other elements mainly play a strengthening role, and a reasonable ratio is of great significance to the extrusion process and the performance of the final product. Therefore, it must be strictly controlled and the scope should not be too wide.
The 6082 alloy is characterized by containing Mn, which is a refractory metal, and the melting temperature should be controlled at 740-760 °C. Stir evenly for more than two times before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform.
The casting temperature of 6082 alloy is high (compared to the normal process of 6063), the casting speed is low, and the water flow is large. The above process needs to be strictly controlled and cannot be exceeded, otherwise it will easily lead to casting failure.
6082 aluminum has high deformation resistance, difficult extrusion, and high mechanical properties. After the homogenization treatment, the alloy microstructure changes as follows: (1) The intragranular segregation disappears; (2) The Ms2Si phase dissolves into α(Al), and the unbalanced eutectic disappears; (3) The β(Al9Fe2Si2) phase turns to α(Al12Fe3Si2 ) phase transformation and refine the iron-containing phase particles.
6082 marine aluminum tubing is heated by power frequency induction heating. The characteristics of this heating method are (1) the heating time is short, and the temperature can reach about 500 ℃within 3 minutes; (2) the temperature control is accurate, and the error does not exceed ±3 ℃.
According to the characteristics and performance requirements of 6082 alloy marine aluminum profiles, the above process is more reasonable. And Haomei 6082 aluminum profile has successfully passed the DNV certification. Welcome to leave message below to inquire it.
