The aluminum content of more than 99.6% is also called 1060 aluminum, which belongs to a commonly used series in the aluminum family. The density of 1060 aluminum is small (ρ = 2.7g / cm3), about 1/3 of iron, and the melting point is low ( 660 ℃), aluminum is a face-centered cubic structure, so it has high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), easy to process, can be made into various profiles and plates, and has good corrosion resistance; However, the strength of 1060 aluminum is very low, and the σb value in the annealed state is about 8 kgf / mm2, so it is not suitable as a structural material.

1060 Aluminum Material Properties

Aluminum alloy has low density but high strength. It is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance

1060 Aluminum Extremely easy to oxidize

In the air, aluminum easily combines with oxidation to form a dense aluminum oxide film (thickness about 0.1-0.2 μm), high melting point (about 2050 ° C), far exceeding the melting point of aluminum and aluminum alloys (about 600). ℃).

The density of alumina is from 3.95 to 4.10 g / cm3, which is about 1.4 times that of aluminum. The surface of the alumina film easily absorbs moisture. When welding, it hinders the fusion of basic metals and easily forms pores, slag inclusions, Defects such as non-fusion, cause degradation of weld performance.

Aluminum alloys can be divided into two types according to machining methods: deformed aluminum alloys and cast aluminum alloys

Deformed aluminum alloy can withstand pressure machining. It can be processed into various shapes and specifications of aluminum alloy materials. Mainly used in the manufacture of aviation equipment, construction windows and doors. Deformed aluminum alloys are divided into non-heat-treatment-reinforced aluminum alloys and heat-treatment-reinforced aluminum alloys.

The non-heat-treatment-reinforced type cannot improve mechanical properties through heat treatment, and can only be strengthened through cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum. Heat-treatment-reinforced aluminum alloys can be improved in mechanical properties through heat treatment methods such as quenching and aging. It can be divided into hard aluminum, wrought aluminum, super-hard aluminum, and special aluminum alloys.

According to chemical composition, cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys, and aluminum-rare earth alloys. Among them, aluminum-silicon alloys have eutectic silicon aluminum alloys, eutectic silicon aluminum alloys, and single alloys. Crystal silicon aluminum alloy, cast aluminum alloy is used in the as-cast state.
