ADC12 aluminum alloy is a commonly used brand of aluminum alloy die castings. ADC12 is a Japanese industrial standard alloy, which is the same as the American A383 Chinese alloy YL113. It is an aluminum alloy raw material that is widely recognized and widely used in the world. It is suitable for the production of various aluminum alloy die castings and is widely used in various aluminum alloy die castings Parts customization, especially auto parts, consumer electronics, radiators, covers, brackets, etc.
ADC12 aluminum alloy material analysis
content
ADC12 is suitable for cold chamber die-casting, with a melting point of 600 °C ±50 °C, and its density is 2.75 g/cm^3. Its chemical composition includes the following elements and their relative concentrations:
Aluminum (Al): Balance. Copper (Cu): 1.5 ~ 3.5% Silicon (Si): 9.6 ~ 12.0% Magnesium (Mg): 0.3 Zinc (Zn): 1.0% Iron (Fe): 0.9% Manganese (Mn) : 0.5% Nickel (Ni): 0.5% Tin (Sn): 0.3%
Among them, we can see that ADC12 contains more silicon, copper, and aluminum, so it is also called AI-SI-CU alloy. Therefore, there are still many limitations in the surface treatment of aluminum alloy die-casting parts.
Mechanical properties
The mechanical properties of aluminum alloy ADC12 are as follows:
- -Tensile strength: ≥ 320MPa
- -Yield strength: ≥ 160MPa
- -Elongation rate: ≥ 3%
- -Impact toughness: ≥ 6J/cm²
physical property
The physical properties of aluminum alloy ADC12 are as follows:
- -Density: 2.7g/cm³
- -Thermal expansion coefficient: 23 × 10 ^ -6/K
- -Thermal conductivity: 96W/(m K)
- -Conductivity: 23.8MS/m
- -Specific heat capacity: 0.9J/(g K)
The content of these elements can be fine-tuned and controlled according to specific needs in order to obtain the desired alloy properties and performance. The chemical composition of ADC12 may vary with different manufacturers, the above values are general ranges. ADC12 aluminum alloy has good heat cracking resistance (strength at high temperature) and mold filling characteristics. It is easy to cast, has good mechanical properties and dimensional stability, and better corrosion resistance. The performance-to-price ratio is very high.
Advantage
Since the ADC12 aluminum alloy has the characteristics of small crystallization temperature interval, large latent heat of solidification, large specific heat capacity, and relatively small linear shrinkage coefficient of the silicon phase in the alloy, its casting performance is generally better than other aluminum alloys. The molding ability is also better, and the tendency of thermal cracking and shrinkage porosity is relatively small. The amount of brittle phase (silicon phase) contained in the Al-Si eutectic is the least, and the mass fraction is only about 10%, so its plasticity is better than that of other aluminum alloy eutectics, and the only remaining brittle phase can be further improved through modification. Improve plasticity. The test also shows that the Al-Si eutectic still maintains good plasticity at a temperature near its freezing point, which is not found in other aluminum alloys. There are often a considerable number of eutectics in the cast alloy structure to ensure its good casting performance; the increase in the number of eutectics will make the alloy brittle and reduce the mechanical properties, and there is a certain contradiction between the two. However, due to the good plasticity of Al-Si eutectic, it can better meet the requirements of both mechanical properties and casting properties, so ADC12 alloy is currently the most widely used die-casting aluminum alloy. We produce aluminum alloy desks and chairs, waiting chairs, auditorium chairs, etc., which use this series of alloy materials.
ADC12 characteristics
- ADC12 aluminum alloy, as one of the most commonly used die-casting materials, is widely used in various fields. It has good processing performance, excellent mechanical properties and high corrosion resistance, making it an ideal choice for many industrial products. Next, we will introduce the characteristics and application of ADC12 aluminum alloy in detail from several aspects.
- ADC12 aluminum alloy has excellent fluidity and filling properties, and is suitable for complex shapes and thin-walled products. Due to its low melting temperature and high fluidity, the die casting process can quickly inject molten aluminum alloy into the mold, and cool and solidify in a short period of time. This makes the ADC12 aluminum alloy have significant advantages in the manufacture of auto parts, electronic device casings, household appliances and other products.
- The ADC12 aluminum alloy has excellent mechanical properties. It has high tensile strength and yield strength, and also has certain toughness and hardness. This makes the products made of ADC12 aluminum alloy have good bearing capacity and impact resistance, which can meet various engineering requirements. For example, in the field of automobile manufacturing, engine parts, suspension systems and wheel hubs made of ADC12 aluminum alloy can bear large loads and provide stable and reliable performance.
- The ADC12 aluminum alloy has high corrosion resistance and can maintain good surface quality and function in harsh environments. To further improve its corrosion resistance, ADC12 aluminum alloy needs to be surface treated. Common surface treatment methods include electrophoretic coating, paint coating, electrostatic spraying, anodizing, and electroplating. By choosing an appropriate surface treatment method, the weather resistance and chemical corrosion resistance of ADC12 aluminum alloy products can be increased, and the appearance of the product can also be improved at the same time.
- ADC12 aluminum alloy also has a lower density and good thermal conductivity. Compared to steel, ADC12 aluminum alloy has a lighter weight, which allows the manufacture of products that reduce the overall weight without compromising strength and stiffness. At the same time, the ADC12 aluminum alloy has good thermal conductivity and can effectively dissipate heat. It is suitable for application scenarios such as electronic device casings and automotive engine components that require heat dissipation.
- ADC12 aluminum alloy has become one of the widely used materials in various industries due to its excellent processing performance, mechanical performance and corrosion resistance. It can not only produce products with complex shapes, but also has good strength and durability. The aluminum alloy ADC12 has good processing performance, and processing methods can be added by die-casting, extrusion, forging and other methods. Among them, die casting is the most commonly used processing method, and various customized aluminum die casting parts can be customized. Its corrosion resistance and aesthetics can be further improved by choosing the appropriate surface treatment method.
