Aluminium alloy materials in Cold Chamber die castings company are 3 materials: aluminium silicon alloy, aluminium copper silicon alloy, and aluminium magnesium alloy;

For aluminium silicon alloys, aluminium-silicon-copper alloys, in addition to aluminium, silicon and copper are the main components; usually, the silicon content is between 6-12%, which is mainly used to improve the flow of alloy liquids. The copper content is second, mainly to enhance the strength and tensile force; the iron content is usually between 0.7-1.2%, within this ratio, the workpiece has the best demoulding effect; through its composition It can be seen from the composition that such alloys cannot be oxidized and colored, and even if desilication oxidation is used, it is difficult to achieve the desired effect.

For aluminium-magnesium alloy, it can be oxidized and colored, which is an important feature that distinguishes it from other alloys.
At present, aluminium alloy die castings are commonly used in A380, A360, A390, ADC-1, ADC-12 and other materials.

ADC12 is equivalent to American Standard A383, and A380 is equivalent to Japanese Standard ADC10. In Japan, ADC12 is widely used, but in the United States, A380 is widely used. The composition of the two is also close, from above comparison, the difference in Si content is larger. ADC12 is 9.5-12%, while the A380 content is 7.5-15%. In addition, the Cu content is also slightly different, ADC12 is 1.5 ~ 3.5%, and A380 is 2.0 ~ 4.0%, and other components are basically the same.

The most commonly used materials in China are ADC12 and ADC6 materials. The main difference between the two materials is that the content of Si, Fe, Cu, Zn, Ni, and Sn in ADC12 is higher than ADC6, while the content of Mg is lower than ADC6. ADC12’s die-casting and machining performance will be better, and corrosion resistance Inferior to ADC6 material.

A380 Aluminium Alloy Application

A380 aluminium alloy is the most common special aluminium alloy, because it combines easy casting, easy machining, good heat transfer and other characteristics. It has strong variability, bearing pressure, and high temperature split resistance. Although A380 has been considered to be easy to machine, it is slightly rough due to the high silicon content. It is widely used in a variety of products, including chassis for electrical equipment, engine mounts, gearboxes, furniture, generators and hand tools.
