Tussen alle series, 1000 series has the most aluminium content, en de zuiverheid ervan kan meer bereiken dan 99.00%. Omdat het geen andere technische elementen bevat, het productieproces is relatief enkelvoudig en de prijs is relatief goedkoop. Het is momenteel de meest gebruikte serie in de conventionele industrie. Momenteel, most of the products in circulation in the market are 1050 En 1060 serie. Het minimale aluminiumgehalte van 1000 series aluminum plate is determined according to the last two Arabic numerals of this series. Bijvoorbeeld, de laatste twee Arabische cijfers van 1050 serie zijn 50. Volgens het naamgevingsprincipe van internationale merken, de producten met aluminiumgehalte hierboven 99.5% moet gekwalificeerd zijn. China's aluminium legering technical standard (GB / t3880-2006) Ook wordt duidelijk bepaald dat het aluminiumgehalte van 1050 bereikt 99.5%. Op dezelfde manier, 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. Afhankelijk van de zuiverheid, het kan worden onderverdeeld in zeer zuiver aluminium en industrieel puur aluminium. Aluminum content is not less than 99.85% of aluminum is high-pure aluminum, and the aluminum content is 99.0% naar 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 naar 180 MPa is also between 60% naar 80%. As the purity of aluminum is lowered, the strength is improved, and the conductivity, corrosiebestendigheid, and plasticity will be reduced. Daarom, different grades of pure aluminum, their use is also different. High-pure aluminum is mainly used in scientific research, chemische industrie, enz .; Life utensils are only 1050 En 1035 grades of pure aluminum.

The role of alloying elements and impurities

IJzer en silicium: 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% naar 1.0%, and the elongation of the alloy was reduced from 36% naar 14.3%; the silicon content increased from 0.002% naar 0.5%, and the elongation was reduced by 36%. To 24.5%. For the molten casting process, het relatieve gehalte aan ijzer en silicium is verschillend, 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% of minder, the alloy has a maximum crack tendency to control W (Fe)> W (En) in this range can prevent crack production. Echter, iron and silicon content are high, and when it is greater than 0.65%, even if W (En)> W (Fe) does not produce cracks.

Koper: 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.

Mangaan, chroom: mangaan, chromium can significantly increase the recrystallization temperature, but the effect of refining the grains is not large.

Titanium, boor: 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. Het effect van titanium op de herkristallisatietemperatuur houdt verband met het gehalte aan ijzer en silicium. When iron is contained, the effect is reduced, but when the silicon content reaches 0.48% (massafractie), 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, koper, ijzer, zink, silicon have less electrically conductive properties, and vanadium, chroom, mangaan, titanium. Reduce more. Impurity reduces its conductive properties to decrease in the order of chromium, mangaan, vanadium, titanium, magnesium, koper, zink, silicium, en ijzer. In aanvulling, 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.

Hot selling 1xxx series metal pure aluminum

Het primaire aluminium heeft een goede vervormbaarheid en oppervlaktebehandeling, en de corrosieweerstand is de beste onder aluminiumlegeringen. Hoe hoger de zuiverheid, hoe lager de sterkte.

1050, 1070, 1080, 1085, 1100 worden vaak gebruikt in mobiele telefoons. Ze worden eenvoudigweg geëxtrudeerd (zonder te buigen). 1050 En 1100 kan worden gebruikt voor chemisch schuren, glad oppervlak, mist oppervlak, normaal effect, voor de hand liggende materiaalkorrel en goed kleureffect; 1080 En 1085 spiegelaluminium wordt vaak gebruikt voor heldere woorden en misteffect, zonder duidelijke materiële korrel. Een reeks aluminium is relatief zacht, voornamelijk gebruikt voor decoratieve of interieuronderdelen.
