DNV Certified Aluminum Plate

Haomei is able to offer dnv certified aluminum plate for shipbuilding and marine industry use. The 5052 aluminum plate , 5083 aluminum plate and 5083 aluminum plate successfully obtained the expanded certification of DNV (Det Norske Veritas), and the 5083, 5086 and 5052 alloy marine grade aluminum plate entered the international marine aluminum plate market. The certification scope of DNV certification of marine products is 5083 alloy, 5086 alloy and 5052 alloy (O, H111, H112, H116, H321 state) medium and heavy plate with a thickness of 3~50mm and a large width of 2400mm product.

dnv certified aluminum plate

The dnv certified aluminum plate offer by Haomei Aluminum are 5083, 5086, 5052 and other 5000 series aluminum alloys (also known as rust-proof aluminum) have high corrosion resistance, good weldability and medium strength, and are widely used in the manufacture of transportation vehicles and ships, sheet metal parts, instruments, hardware products and electrical enclosures, etc. However, in the marine grade aluminum plate product market, Classification societies require manufacturers to strictly abide by the normative standards in the marine field, and on the basis of the rigor of laboratory inspection qualifications, and only allow enterprises to enter the marine board market after certification with almost harsh requirements. This undoubtedly poses a serious challenge to marine aluminum plate technology, quality and production management. Only aluminum plate manufacturers with high quality control can get this certification.

The dnv certified aluminum plate produced by Haomei Aluminum also have passed CSS certificate with 5052, 5083 and 5086 aluminum alloy. It should be noted that on-site certification, raw and auxiliary materials inspection and assurance during melting and casting production, composition control in the smelting process, the heating temperature of hot rolling and the results of mechanical properties affected by the control of rolling temperature, and the annealing process of the sheet are a series of production processes. Such a complex certification process tests the ability of marine grade aluminum plate manufacturer to integrate resources.
