The application field of the aluminum alloy products(1)

Aluminum alloy(aluminum alloy products) has the characteristics of low density, good mechanical properties, good processability, non-toxic, easy recovery, excellent conductivity, heat transfer and corrosion resistance. It is widely used in marine industry, chemical industry, aerospace, metal packaging, transportation and other fields.

Aerospace(aluminum alloy products)
Aluminum alloy is the main material for making aircraft. Compared with mild steel for automobile, aluminum alloy has expensive price and low density, with a relative density of 2.8. Compared with mild steel with a relative density of 7.8, it is about one-third lighter. Although the strength difference is not much, for aircraft, light material is the most important, with strong corrosion resistance and convenient processing. Therefore, aluminum alloy is the most ideal material for aircraft.

Duralumin can manufacture rivets, aircraft propellers and high-strength parts on aircraft according to its different alloy element content; Superhard aluminum is a kind of hard aluminum containing zinc. Its hardness and strength are higher than that of hard aluminum. Different kinds of superhard aluminum are used to manufacture various structural parts and high load parts. It is one of the important materials in the aviation industry.

Marine industry(aluminum alloy products)
Aluminum and aluminum alloys are more and more widely used in the shipbuilding industry, ranging from motor boats to 10000 ton oil tankers, from offshore hovercraft to submarine, from civil to military, from fishing ships to marine mining ships. Aluminum alloys with excellent comprehensive performance are used to produce ship shells, support structures, supporting facilities, pipelines, etc.

The application of aluminum alloy in marine industry can reduce the overall weight of the ship, improve the running speed of the ship, and resist the corrosion of seawater to the ship. Aluminum alloys used in marine industry are mainly aluminum copper alloy, aluminum magnesium alloy and aluminum silicon alloy. Aluminum copper alloy is widely used in ships in China and Russia, but its poor seawater corrosion resistance hinders its development in the shipbuilding industry. Aluminum magnesium alloy is mainly used for hull shell, water pump conduit, pump shell and base support, with grades of 5083, 5086, 5456, 5466, etc. Aluminum silicon alloy has moderate structural strength, good fluidity and strong filling capacity. It is easy to produce parts with high density and complex structure, such as high-pressure valve, cylinder block, pump, reducer housing, turbine blade, etc.
