DNV Certified Marine Grade Aluminum

2022-08-24

The DNV certified marine grade aluminum 5083, 5056, 5052, 5383, 5059, 6061 alloy sheet products have specifications (thickness × width) 3-50 × 1100-2650 mm for marine engineering and high-tech ships. The residual heat of continuous rolling and coiling realizes self-annealing, and the "1+4" short-flow production technology of hot continuous rolling for marine grade aluminum plate products is established, eliminating the need for recrystallization annealing, cold rolling, intermediate annealing, cleaning, and stabilization after hot continuous rolling. Chemical annealing and other processes shorten the production cycle by 3-7 days, reduce the production cost, and achieve cost reduction and efficiency increase.

 
The DNV certified marine grade aluminum quality indicators such as product mechanical properties, corrosion resistance, plate shape and surface quality can meet Norway's requirements. Classification Society (DNV.GL), American Bureau of Shipping (ABS), China Classification Society (CCS) and customer requirements. The application features of certified marine grade aluminum plate are:
1, It can reduce the weight of the ship, increase the speed, reduce the consumption of fuel, improve the aspect ratio of the ship, and increase the stability;
2, Good corrosion resistance, can increase the service life of the ship;
3, Good processing formability, easy to carry out various forms of processing such as cutting, stamping, cold bending, forming and cutting, suitable for streamlined hull;
4, Good welding performance, small elastic modulus, large ability to absorb impact stress, and greater safety;
5, Materials are easily available and recyclable;
6, Good low temperature performance, suitable for low temperature equipment.
 
Haomei Aluminum have a large number of DNV certified marine grade aluminum slabs, and can produce marine aluminum sheets of various specifications according to user orders. The material and quality can stand the test. Haomei Aluminum use the most advanced rolling equipment, annealing equipment and straightening machine are used for production, and the plate shape, internal microstructure and grain size are well guaranteed.
