The main advantages and working temperature of aluminum alloy die casting

Dec 08,2021

Aluminum alloy die casting occupies a very important position in today's industry. It has a very wide range of uses in many industries. With the continuous development of society, people's life needs are also increasing. In operation, the demand for aluminum alloy die-casting process is also increasing. 1. The main advantages of aluminum alloy die-casting 1. Aluminum alloy die-casting parts are beautiful in appearance and light in weight. It is easy to transport during operation. It is also a big advantage to use it in a car. 2. The density of aluminum alloy is significantly lower than that of cast iron and cast steel, but its strength and corrosion resistance are much higher. Therefore, under the same load weight, the use of aluminum alloy die-casting can greatly reduce the structural weight. 3. The aluminum alloy has good surface gloss and good casting performance. The mechanical properties and tensile strength of aluminum alloy die castings have great resistance during manufacture. To a certain extent, their elongation is a measure of the brittleness and plasticity of materials. Hardness refers to the resistance of the surface of a material to plastic deformation caused by the pressing or friction of hard materials. Aluminum alloy die castingThe working temperature and humidity of the workpiece, the medium and air tightness of the workpiece contact, and the accuracy and dimensional stability of the entire product. To a certain extent, the surface accuracy and surface roughness of aluminum alloy die castings will directly affect the working efficiency, energy consumption and cavitation development of the pump and hydraulic system. The strength and shock resistance of internal combustion engine cylinder blocks, cylinder heads, cylinder liners, piston rings and exhaust pipes directly affect the service life of the engine. Compared with other casting methods, sand casting has low cost, simple production process and short production cycle. It is aluminum alloy die casting. When the wet mold fails to meet the requirements, consider the use of clay sand dry sand molds, dry sand molds or other sand molds. The casting method of aluminum castings should be compatible with the production batch. Low pressure casting, die casting, centrifugal casting and other casting methods are only suitable for mass production due to the high cost of equipment and molds. Aluminum castings can be single-piece casting or mass production. 2. What causes the molten slag of aluminum alloy die-casting? According to the manufacturing process, aluminum alloy die-casting can be divided into two categories: cast-type zinc alloy die-casting and wrought zinc alloy die-casting. The output of cast zinc alloy is much larger than that of wrought zinc alloy. Listed below are the properties, properties and uses of several important zinc alloys. Cast zinc alloy; according to different casting methods, it is divided into pressure casting zinc alloy (solidified under the action of external pressure) and gravity casting zinc alloy (solidified only under the action of gravity). Die casting zinc alloy. Since this alloy was used in the automobile industry in 1940, the output has increased sharply. Among the total zinc consumption, about 25%, 0.004%, 0.003%, 0.02%, so zinc alloy die casting should be used High-purity zinc with a purity of 99.99% is used as a raw material. Gravity casting zinc alloy can be cast in sand molds, plaster molds or hard molds. This kind of zinc alloy not only has the characteristics of general zinc alloy die-casting, but also has high strength and good casting performance. The cooling rate has no obvious influence on the mechanical properties. The residues and scraps produced in the production of zinc alloy die-casting parts can be recycled and the gate is simple. It is not sensitive to overheating and remelting, has small shrinkage, less pores, can be electroplated, and can be finished by conventional methods. Wrought zinc alloy: In addition to traditional varieties of wrought zinc alloys used in industry, ZN-1CU-0.1TI and ZN-22AL alloys have appeared. After the former is rolled, because of the TIZN15 intermetallic compound dispersed particles arranged in rows along the rolling direction, it can hinder the movement of grain boundaries.
