Among all series, 1000 series has the most aluminum content, and its purity can reach more than 99.00%.  Because it does not contain other technical elements, the production process is relatively single and the price is relatively cheap. It is the most commonly used series in conventional industry at present. At present, most of the products in circulation in the market are 1050 and 1060 series. The minimum aluminum content of 1000 series aluminum plate is determined according to the last two Arabic numerals of this series. For example, the last two Arabic numerals of 1050 series are 50. According to the naming principle of international brands, the products with aluminum content above 99.5% must be qualified. China's aluminum alloy technical standard (GB / t3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. Similarly, the aluminum content of 1060 series aluminum must reach more than 99.6%.

Properties and uses of alloys

The aluminum content of the 1xxx series aluminum alloy is not less than 99.0%, also known as the pure aluminum. Depending on the purity, it can be divided into high purity aluminum and industrial pure aluminum. Aluminum content is not less than 99.85% of aluminum is high-pure aluminum, and the aluminum content is 99.0% to 99.85% (99.85%) for industrial pure aluminum. The system has a small density, good conductivity, high thermal conductivity, large melting, high light reflection coefficient, and a small amount of heat in the absorption cross-sectional area of ​​the heat. Aluminum can generate a dense and sturdy oxide film in the air to prevent oxygen intrusion and therefore has better resistance. The heat treatment of 1xxx aluminum alloy cannot achieve the enhanced effect, and can only use the cooling hardening method to increase the strength. The pure aluminum strength is low, and only 150 to 180 MPa is also between 60% to 80%. As the purity of aluminum is lowered, the strength is improved, and the conductivity, corrosion resistance, and plasticity will be reduced. Therefore, different grades of pure aluminum, their use is also different. High-pure aluminum is mainly used in scientific research, chemical industry, etc .; Life utensils are only 1050 and 1035 grades of pure aluminum.

The role of alloying elements and impurities

Iron and silicon: Iron and silicon are the main impurities in the 1xxx tidal alloy, and their content and relative proportion have a large impact on performance. As in the 1A99 alloy ingredient, the iron content increased from 0.001 7% to 1.0%, and the elongation of the alloy was reduced from 36% to 14.3%; the silicon content increased from 0.002% to 0.5%, and the elongation was reduced by 36%. To 24.5%. For the molten casting process, the relative content of iron and silicon is different, and the tendency of the ingot forming crack is also different.

Within the high-pure aluminum, since the iron, the silicon content is very small, silicon can dissolve in the matrix, and the cracks of the ingot tend to be small. Within industrial pure aluminum, when iron and silicon content is about 0.65% or less, the alloy has a maximum crack tendency to control W (Fe)> W (Si) in this range can prevent crack production. However, iron and silicon content are high, and when it is greater than 0.65%, even if W (Si)> W (Fe) does not produce cracks.

Copper: Copper is mainly present in a solid solution state in a 1xxx system alloy, and the strength of the alloy is increased.

Magnesium: Magnesium can be added in the 1xxx liner, and mainly in a solid solution state, its effect is to increase the alloy strength, which has a small effect on the recrystallization temperature.

Manganese, chromium: manganese, chromium can significantly increase the recrystallization temperature, but the effect of refining the grains is not large.

Titanium, boron: titanium, boron is the main metamorphic element in the 1xxx tie, can be finely refined, and the recrystallization temperature and fine grains can be refined. The effect of titanium on the recrystallization temperature is related to the content of iron and silicon. When iron is contained, the effect is reduced, but when the silicon content reaches 0.48% (mass fraction), titanium can improve the recrystallization temperature.

Adding elements and impurities have a large effect on the electrical properties of 1xxx aluminum alloys, generally reduced electrical conductivity, of which nickel, copper, iron, zinc, silicon have less electrically conductive properties, and vanadium, chromium, manganese, titanium. Reduce more. Impurity reduces its conductive properties to decrease in the order of chromium, manganese, vanadium, titanium, magnesium, copper, zinc, silicon, and iron. In addition, impurity copper and zinc will reduce the resistance, manganese and silicon of aluminum, and iron will also form a crispy phase, affecting the plasticity of 1xxx aluminum alloy.

According to the product type, it can be divided into

Hot selling 1xxx series metal pure aluminum

The primary aluminum has good formability and surface treatment, and its corrosion resistance is the best among aluminum alloys. The higher the purity, the lower the strength.

1050, 1070, 1080, 1085, 1100 are commonly used in mobile phones. They are simply extruded (without bending). 1050 and 1100 can be used for chemical sanding, smooth surface, fog surface, normal effect, obvious material grain and good coloring effect; 1080 and 1085 mirror aluminum are often used for bright words and fog effect, without obvious material grain. A series of aluminum are relatively soft, mainly used for decorative or interior parts.
