Do you understand the role of each metallic element in die-cast aluminum alloy?

1. Silicon (Si) Silicon is the main element in most die-casting aluminum alloys. It improves the casting performance of the alloy, generally ranging from 7% to 11%. Functions of silicon: 1. Improves high-temperature fluidity 2. Reduces shrinkage 3. Reduces the tendency of thermal cracking 4. Improves wear resistance However, when the silicon content exceeds 12%, silicon and aluminum form a eutectic, and when impurities such as copper and iron are present, free silicon hard spots appear, making machining difficult. High-silicon aluminum alloys severely corrode the crucibles of castings. 2. Copper (Cu) The copper content in the alloy is usually between 2.5% and 5%. Increasing the copper content,

Advantages of aluminum die castings

Aluminum die casting is a pressure casting process that uses a pressure die casting machine with a mold to inject molten aluminum or aluminum alloy into the machine's inlet. The molten metal is then cast under pressure to create aluminum or aluminum alloy parts with the shape and size of the mold. These parts are commonly known as aluminum die castings. Advantages: (1) It can produce metal parts with complex shapes, clear contours, and thin walls and deep cavities. Because the molten metal maintains high fluidity under high pressure and high speed, it is possible to obtain metal parts that are difficult to process using other methods. (2) Die castings have high dimensional accuracy, reaching IT11

Why is it necessary to use a high-temperature mold release agent when die casting products?

Why must a high-temperature mold release agent be used for die-casting products? Die-casting release agents are suitable for aluminum, magnesium, and zinc alloy die-casting products and are now widely used in the automotive, telecommunications, motorcycle, and home appliance industries. Aluminum alloy die-casting release agents are auxiliaries used in the die-casting production process. Therefore, mastering the application technology of aluminum die-casting release agents is essential. Due to the different volumes, sizes, structural complexities, and post-processing requirements of die-cast products, the requirements for release agents also vary. Die-casting release agent technical parameters: Appearance: Milky white emulsion. Density: 0.97g/
