Functions and effects of various elements in aluminum alloy of aluminum alloy die castings:
Silicon: the main element in aluminum alloy. It can improve the casting performance of the alloy. Silicon and aluminum can form a solid melt.
Magnesium: it can improve strength and yield limit, machinability and corrosion resistance.
Zinc: zinc can improve fluidity, increase thermal brittleness and reduce corrosion resistance.
Iron: when the iron content is less than 6% in the working, it can reduce the adhesion to the mold.
Manganese: Manganese in aluminum alloy can reduce the harmful effect of iron and change iron into needle like structure into fine crystal structure, with 5% moderate.
Nickel: it can improve strength and hardness and reduce corrosion resistance. It has the same effect as iron.
Titanium: it can refine the grain structure, improve the mechanical properties and reduce the hot crack inclination of the alloy.
For the packaging of aluminum alloy die-casting products, the most important thing is to protect the goods inside, but now the exquisite appearance of the packaging box is also something we must consider.
(1) equality: the quality of a product itself should be consistent with the external packaging, so the selection of packaging box materials should also be divided into high-grade and poorly packaged aluminum alloy die-casting products according to the level of packaging items. Therefore, in order to ensure the safety of the product, packaging materials with better performance are needed.
(2) adaptability: when transporting products, we also need to consider that the packaging materials can adapt to the transportation conditions, the long-term route and the mode of transportation. There are obvious temperature differences in the climate and environment in different regions, which also makes manufacturers need to be cautious in selecting packaging materials. In addition, such as auto parts, electronics, sports equipment, photographic equipment, fishing gear, lighting, all kinds of electric tools and so on. The requirements for packaging materials are also different, so Shenzhen Furong Precision Die Casting Co., Ltd. needs to choose what kind of packaging materials according to what kind of transportation mode it chooses.
