The main advantages of aluminum die castings and their operating temperature

Aluminum die castings play a very important role in the current industry. They are widely used in many industries. With the continuous development of society, people’s living needs are getting higher and higher. The use of aluminum die casting china process The demand is also increasing.

The main advantages of aluminum die casting

  • 1. Aluminum die-casting parts are beautiful in appearance and light in weight, and can be easily transported during operation. It is also a great advantage to use in automobiles.
  • 2. The density of aluminum alloy is obviously lower than that of cast iron, cast steel, etc., but its strength and corrosion resistance are much higher. Therefore, under the same load weight, the use of aluminum die casting can greatly reduce the structural weight.
  • 3. For the surface of aluminum alloy, its surface gloss is very good, and it also performs well in casting performance.

The mechanical properties and tensile strength of aluminum die-casting parts are great resistance when the material is broken during production. To a certain extent, its elongation is a measure of the brittleness and plasticity of the material. The hardness is the surface of the material against hard objects. Resistance to plastic deformation caused by pressing or friction.

The working temperature and humidity of aluminum die castings, the medium and air tightness requirements of the workpiece contact, the accuracy and dimensional stability that the entire product can meet.
The accuracy and surface roughness of aluminum die-casting parts will directly affect the working efficiency of its pump and hydraulic system, energy consumption and the development of cavitation to a certain extent, internal combustion engine cylinder block, cylinder head, cylinder liner, piston ring , The strength and resistance of aluminum castings such as exhaust pipes directly affect the working life of the engine.

Aluminum die castings are given priority to sand casting. The main reason is that sand casting has lower cost than other casting methods, simple production process and short production cycle. When the wet type cannot meet the requirements, consider using clay sand surface dry sand type, dry sand type or other sand types. The casting method of cast aluminum parts 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 price of equipment and molds. Cast aluminum parts can be cast in a single piece or mass production.
