Marine Grade Aluminium 5083

Based on the excellent welding and machining properties of marine grade aluminium 5083 alloy, it is widely used in ships, ships, offshore platforms and coastal structures. 5083 marine grade aluminum alloy is a low-density material. Because of its high strength, good plasticity, excellent workability and corrosion resistance, it is widely used in the shipbuilding industry and is one of the important materials for ship plates and hulls.

Marine corrosion and protection of marine grade aluminium 5083 alloys in the marine environment. Aluminum has a higher specific strength, good plasticity and ductility; the conductivity of aluminum is second only to silver and copper, and it has almost no effect on electromagnetics. Aluminium sheet 5083 has good thermal conductivity and good reflection ability to light and heat. Adding other factors to aluminum to make alloys can greatly improve its mechanical properties. Therefore, it is used in machinery, chemical industry, electronics, today, transportation, civil construction, food It is widely used in various fields such as light industry and military industry. Many aluminum alloys also have good corrosion resistance in seawater, and their applications in marine environments are increasing.

Marine grade aluminium 5083 have the advantages of high specific strength, good thermal and electrical conductivity, strong light reflection, beautiful color, non-magnetic, good corrosion resistance, good plasticity and formability, and no low temperature brittleness. It is a kind of excellent comprehensive performance Non-ferrous materials. Aluminum and aluminum alloys are widely used in various sectors of the national economy, and have become the second largest metal material after steel in terms of output and use. The oxide film on the surface of aluminum and aluminum alloy is the main reason why aluminum alloy is resistant to atmospheric corrosion and liquid environment corrosion. Once it exists in a corrosive medium containing a large amount of corrosive anions such as chloride and oxygen, the corrosive anions can reach through the oxide film. The surface of aluminum and aluminum alloy substrates causes pinhole corrosion or other types of corrosion of aluminum alloy. With the development of the application of aluminum alloy materials, its surface treatment technology has also developed rapidly. Surface treatment can improve the load carrying capacity and wear and corrosion resistance of aluminum and aluminum alloys, and generally includes aluminum anodizing, chemical conversion, organic coating coating, electroplating, electrophoresis and other treatment processes.
