Want to make aluminum alloy forging products but don’t know how to choose the material? I come to talk to you about this aspect.
Factors affecting the selection of aluminum alloy forging products
How to choose the material of aluminum alloy forging products, which is mainly related to the use of the product scene and processing technology. We often say that a series of aluminum alloy is closer to pure aluminum, as its texture is relatively soft; two series and seven series belong to the super hard aluminum alloy, which is not easy to anodic oxidation; and five series and six series aluminum alloy, is a very pro-industrial grade aluminum, is very suitable for machining. Below is a detailed description of the eight familiar series of aluminum alloys.
Series 1 Aluminum Alloy (“Pure Aluminum”)
Because its pure aluminum content is over 99%, it produces the best aluminum oxide. In bright anodizing, after brightening and anodizing, the higher the purity of aluminum, the better the specular reflection of light on the surface is maintained, i.e., the smaller the amount of “loss of light”. In the protective anodic oxidation treatment, the higher the purity of aluminum, the anodic oxide film corrosion resistance is also significantly improved.
2 series aluminum alloy (Al-Cu alloy)
The highest content of copper elements, about 3-5% or so, characterized by high hardness, not often used in conventional industry, belongs to aviation aluminum. 2024 for aluminum, copper, and magnesium system in the typical hard aluminum alloy, is a heat-treatable alloy, after heat treatment, the mechanical properties of a significant increase (its T3 state parameters are as follows: tensile strength of 470MPa, 0.2% yield strength of 325MPa, elongation: 10%, fatigue strength of 105MPa, the fatigue strength of 105MPa, the state parameters of the T3 state are as follows: 470MPa, 0.2% of yield strength of 325MPa, elongation: 10%, fatigue strength of 105MPa. 10%, fatigue strength 105MPa, hardness 120HB), commonly used in aircraft structures, rivets, truck hubs, propeller components and other structural parts.
3 series aluminum alloy (Cu-Mg alloy)
With manganese as the main component, the manganese content is about 1.0-1.5%, which is a series with a better anti-rust function. Our 3000 series production process is more excellent and often used in air conditioners, refrigerators, under the car, and other humid environments.
4 series aluminum alloy (Al-Si alloy)
Usually, silicon cois content between 4.5-6.0%, containing silicon with higher strength is relatively high, 4000 series aluminum bar on behalf of the 4A01, 4000 series of aluminum plate belongs to the series with the high silicon content. Soup flow is good, solidification shrinkage is less, belongs to the construction materials, mechanical parts, forging materials, and welding materials; low melting point, good corrosion resistance, heat-resistant, and wear-resistant properties.
5 series aluminum alloy (Al-Mg alloy)
5 series of heat treatment can not be strengthened deformation of aluminum alloys, in industrial applications, the magnesium content of the alloy is generally not higher than 5.5%. This is a more versatile aluminum alloy, which can be used to make bright products, as well as in the food industry, chemical industry, shipbuilding marine environment, etc. The 5 series has relatively good corrosion resistance and can be welded. Alloys with higher aluminum content (e.g., 5043, 5305, etc.) can be used to manufacture bright products and for decorative occasions. 5××× series aluminum alloys have better corrosion resistance after anodizing.
6 series aluminum alloy (Al-Mg-Si alloy)
6 series belongs to the heat treatment and can strengthen deformation of aluminum alloy, engineering applications are important, mainly for extrusion profiles, high strength such as 6061 aluminum alloy (forging 6061 aluminum), 6063 aluminum is also used for the production of the plate.
6063 aluminum alloy is the most widely used extruded aluminum alloy. In bright anodizing, 6463 aluminum alloy is usually recommended, and its aluminum content is at least 99.7%. The lower the impurity elements (e.g. iron, manganese) in the alloy, the lower the loss of brightness after anodizing.
7 Series Aluminum Alloy (Al-Zn-Mg-Cu Alloy)
Containing mainly zinc, 7000 series aluminum alloy represents 7075 T6 aluminum. Also belongs to the aviation series, it is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, belongs to the super-hard aluminum alloy, and has good abrasion resistance.
8 series aluminum alloy aluminum elements which are not the main component, belong to other series.
Six series aluminum alloy forging products in industrial manufacturing forging, generally choose 6063-grade and 6061-grade aluminum alloy forging products; and five series and six series of two kinds of aluminum alloy forging can be mixed and matched, mixed and matched under the products made in the appearance of almost no difference.
