Inleiding tot 1000-9000 serie aluminiumlegeringen

1000-9000 series aluminum alloys can roughly summarize all aluminum alloys. Aluminum alloys can be divided into different series due to different alloy compositions and properties.

1000 serie aluminiumlegering

1000 serie: 1000 serie aluminiumlegering represents 1050, 1060 En 1100 serie. De 1000 series contains the most aluminum among all series. The purity can reach more than 99.00%. Since it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is currently the most commonly used series in conventional industries. Most of the ones currently circulating on the market are 1050 En 1060 serie.

The minimum aluminum content of the 1000 series aluminum plates is determined based on the last two Arabic numerals of the series. Bijvoorbeeld, the last two Arabic numerals of the 050 serie zijn 50. Volgens de internationale merknaamgevingsprincipes, het aluminiumgehalte moet meer dan bereiken 99.5% een gekwalificeerd product te zijn. de technische normen voor aluminiumlegeringen van mijn land (gB/T3880-2006) also clearly stipulate that the aluminum content of 1050 must reach 99.5%. Op dezelfde manier, het aluminiumgehalte van 1060 series aluminum plates must reach more than 99.6%.

Industrial pure aluminum has the general characteristics of aluminum, including low density, goede elektrische en thermische geleidbaarheid, goede corrosiebestendigheid, and good plastic processing properties. It can be processed into plates, strips, folies, and extruded products. It can be used for gas welding, chlorine arc welding, and spot welding. weld.

Functies: Contains more than 99.00% aluminium, has good electrical conductivity, goede corrosiebestendigheid, good welding performance, lage sterkte, en kan niet worden versterkt door warmtebehandeling.

Sollicitatie: Hoogzuiver aluminium (bevat meer dan 99.9% aluminium) is mainly used for scientific experiments, chemical industry and special purposes

Functies: Aluminum-containing alloy with copper as the main alloying element. Magnesium, lead and secretion are also added for machinability.

Bijvoorbeeld: 2011 legering, pay attention to safety protection during the smelting process (harmful gases will be produced). 2014 alloy is used in the aerospace industry with high strength. 2017 alloy is a bit less strong than 2014 legering, but easier to machine. 2014 can be heat treated and strengthened.

Disadvantages: Serious intergranular corrosion tendency.

Sollicitatie: aviation industry (2014 legering), screws (2011 legering) and industries with higher operating temperatures (2017 legering).

Functies: Aluminum alloy with manganese as the main alloy element, cannot be strengthened by heat treatment, has good corrosion resistance and good welding performance. Good plasticity. (Close to super aluminum alloy).

Disadvantages: Low strength, but strength can be enhanced through cold work hardening. It is easy to produce coarse grains during annealing.

Sollicitatie: Oil-conducting seamless pipes (3003 legering) used on aircraft, blikjes (3004 legering).

Haalbaarheid van anodiseren: Lxxx series aluminum alloys are also called “pure aluminum” and are generally not used for hard anodizing. But it has good properties in bright anodizing and protective anodizing.

2000 serie aluminiumlegering

2000 Serie: De 2000 series aluminum alloy represents 2024, 2A16 (LY16), and 2A02 (LY6). De 2000 series aluminum plate is characterized by high hardness, among which the copper content is the highest, over 3-5%. 2000 series aluminum rods are aviation aluminum materials and are currently not commonly used in conventional industries.

Duralumin: code 2XXX, commonly used ones are 2A11, 2A12, enz. Duralumin has good mechanical properties, Grote sterkte (Bijvoorbeeld, the tensile strength of 2A12-T4 can reach more than 469MPa), easy to process, and low density, so it can be used as a lightweight structural material. In general hard aluminum, magnesium does not exceed 2%. Yu can improve strength and corrosion resistance, but manganese is generally limited to less than 1%. Adding a small amount of zinc can refine the grains. Both iron and silicon are limited to less than 0.5-0.6%, and it is hoped that the iron-silicon ratio is greater than or equal to one.

The main disadvantages of hard aluminum are:

• 1) The corrosion resistance is poor, so it is necessary to roll a layer of industrial pure aluminum on the surface of the duralumin plate (the thickness of pure aluminum accounts for 3-5% of the thickness of the plate) to become aluminum-clad duralumin. The strength is reduced when there is an aluminum cladding layer.
• 2) The temperature range of solid solution treatment is narrow. Below this temperature, the maximum strengthening effect cannot be exerted. If the upper limit temperature is exceeded, the grain boundary may “pass” and the grain aggregation may be destroyed.
• 3) Welding cracks tend to be large, making it difficult to use fusion welding.
• 4) Haalbaarheid van anodiseren: 2xxx series aluminum alloys are also called “aluminum copper magnesium alloys”. Since the AL-Cu intermetallic compounds in the alloy are easily dissolved during anodizing, it is difficult to form a dense anodic oxide film on the protective anode. When oxidized, its corrosion resistance is worse, so this series of aluminum alloys are not easy to anodize.
