1050 Aluminum Plate

Definition of 1050 aluminum plate

The 1050 aluminum plate and strip belong to a product in the pure aluminum plate series. The chemical composition and mechanical properties of the 1060 series products are similar, and they are basically replaced by the 1060 aluminum plate and strip in the application. The last two Arabic numerals of the 1050 series are 50. According to the international brand naming principle, the aluminum content must reach more than 99.5% to be qualified products. my country’s aluminum alloy technical standard (GB/T3880-2006) also clearly stipulates that the aluminum content of 1050 should reach 99.5%. Since it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in conventional industries.

Specification for Heat Treatment of 1050 Aluminum

1) Complete annealing: Heating at 390~430°C; depending on the effective thickness of the material, the holding time is 30~120min; cooling to 300°C with the furnace at a speed of 30~50°C/h, and then air cooling.

2) Rapid annealing: heating at 350~370℃; the holding time is 30~120min depending on the effective thickness of the material; air or water cooling.

3) Quenching and aging: Quenching at 500~510℃, air cooling; artificial aging at 95~105℃, 3h, air cooling; natural aging at room temperature 120h.

Characteristics of 1050 aluminum plate

Industrial pure aluminum has the general characteristics of aluminum, low density, good electrical and thermal conductivity, good corrosion resistance, good plastic processing performance, can be processed into plates, strips, foils and extruded products, etc. spot welding.

Industrial pure aluminum cannot be strengthened by heat treatment, and its strength can be improved by cold deformation. The only form of heat treatment is annealing. The starting temperature of recrystallization is related to the impurity content and degree of deformation, generally around 200 °C. σb=80~100MPa of annealed sheet, σ0.2=30~50MPa, ζ=35%~40%, HB=25~30. After 60%~80% cold deformation, although the disorder can be increased to 150~180MPa, the ζ value has dropped to 1%~1.5%. Increasing the content of iron and silicon impurities can improve the strength, but reduce the plasticity, electrical conductivity and corrosion resistance.

Application of 1050 aluminum plate

1050 aluminum plate is often used in daily necessities, lighting fixtures, reflectors, decorations, chemical industry containers, heat sinks, signs, electronics, lamps, nameplates, electrical appliances, stamping parts and other products. In some occasions that require high corrosion resistance and formability, but do not require high strength, chemical equipment is its typical use.
