As a metal processing technology, aluminum casting has significant advantages and unique process characteristics.
Its advantages are mainly reflected in the following aspects:
1. Lightweight: Aluminum alloy has a low density, and the cast parts are light, which is conducive to energy conservation and emission reduction.
2. High strength: Although aluminum alloy has a low density, its strength is very high and can meet many complex and demanding application scenarios.
3. Good corrosion resistance: Aluminum and its alloys have good corrosion resistance in the atmosphere and can resist the erosion of various chemicals.
4. Good electrical and thermal conductivity: Aluminum is an excellent electrical and thermal conductive material suitable for electrical and electronic fields.
5. Aluminum tin has good fluidity and can easily fill complex shapes and can achieve twisted liquid castings and smooth surfaces.
The processes of aluminum casting process:
1. Die design: Aluminum casting requires accurate molds to ensure the size and shape of the castings are precisely controlled.
2. Melting and casting: Aluminum alloys need to be melted under controlled conditions to maintain the stability of their composition and performance.
3. Cooling and solidification: Casting requires cooling and solidification after casting to achieve the required structure and performance.
4. Post-processing: After the casting is cooled, heat treatment, machining, surface treatment and other post-processing may be required to meet the use requirements.
In general, aluminum casting has been widely used in aviation, automobile, electronics, construction and other fields due to its unique advantages and process characteristics.
