marine grade aluminum plate

Marine aluminum plate is the emerging market for R & D applications of aluminum products. Shipboard production capacity has also become an important indicator of the comprehensive strength of various aluminum processing enterprises. With the upgrading of domestic aluminum production process, leading enterprises in Henan Province - Haomei aluminum plate production scale gradually expanded, increasingly rich types of alloys, product performance has reached the international advanced level.

At present, Haomei 5083 aluminum plate, 5086 aluminum plate, 5754 aluminum plate and other products, has entered the world shipbuilding market, mainly used in the ship's deck, the engine platform, the ship side, the bottom of the ship and other components.

Marine aluminum alloy is one of the emerging areas of aluminum products, but also the transformation and upgrading of many domestic aluminum processing enterprises focus on the direction. Marine aluminum alloy because it is used for marine ships and other fields, so than other ordinary aluminum products, there are more stringent process requirements and performance standards.

From the development of marine aluminum, at present, many domestic aluminum manufacturers have begun to focus on research and development 5 series, 6 series of marine aluminum, increase scientific research, expand production scale, into the marine aluminum and other high-end manufacturing market. To the national aluminum processing enterprises - Haomei Aluminum, for example, its 5083,5086,5454 and other aluminum by 2015 China Classification Society certification, in October and passed the Norwegian Classification Society certification, made foreign trade aluminum "world License ", which will be the company's marine aluminum market to open up a broader space for development, but also for the domestic shipboard enterprises to upgrade and play a positive role model.

Advantage s of Haomei Marine grade aluminum plate

  • 1. Advanced production equipment, strong processing capacity, - made Haomei marine aluminum plate of excellent quality.

  • 2. Strong processing capacity - Hao Mei marine aluminum with an annual output of 200,000 tons to help customers seize the market.

  • 3 . Authoritative international certification - for the Hao Mei quality board to ensure quality

  • 4. Low density, high strength, reduce the ship weight
    The low density, high strength, high rigidity and corrosion resistance of aluminum make the aluminum ship 20% lighter in weight compared to ships made of steel or other alloy materials. This can reduce ship weight and reduce energy

  • 5. Corrosion resistance, durable, economic and environmental protection
    Haomei marine aluminum alloy of high toughness, corrosion resistance and weldability, for the strict production of the ship may be possible. At the same time, the Haomei board can be more resistant to the ocean climate in the atmosphere, steam, water and other media corrosion, durable, more economical.
