Information

The difference between aluminum alloy and aluminum-the difference between pure aluminum and aluminum alloy:

One, the characteristics are different

1. Aluminum alloy: a kind of rare metal construction materials commonly used in industry.

2. Pure aluminum: silver light metal.

Two, the characteristics are different

1. Aluminum alloy: Aluminum alloy has low relative density, but high compressive strength, close to or beyond heat-resistant cast iron, good plastic deformation, and can be produced and processed into various aluminum profiles. It has excellent electrical conductivity, heat transfer and corrosion resistance. It is widely used in industry, and its use is second only to steel. Some aluminum alloys can obtain excellent physical properties, process properties and corrosion resistance after heat treatment.

2. Pure aluminum: soluble in dilute hydrochloric acid, dilute nitric acid, sulfuric acid, sodium hydroxide solution, iron trichloride solution, insoluble in water, but can react slowly with boiling water, forming density 2.70, elastic mold 70Gpa, Poisson's ratio 0.33. Melting point is 660℃. Melting point 2327°C.

Three, the application is different

1. Aluminum alloy: Aluminum alloy can be used for aircraft skins, load-bearing beams, ribs, truss structures, baffles and landing gears. The aircraft uses different total amounts of aluminum depending on the purpose. Because aluminum alloys are of high quality and low price, civil aircrafts with economic benefits as the key have been widely used.

2. Pure aluminum: Aluminum is widely used in household appliances manufacturing industry, cable and wire industry and wireless communication industry.
