What Is Aluminum Casting?
Aluminum casting is a kind of metalworking process. By pouring molten aluminum into a precision-designed die or mold. After cooling, the part is removed from the mold. Then get the desired shape casting parts. The mold must be made with precision. Because its quality will have a direct impact on the shape and surface of the finished aluminum alloy casting.
Compared with steel or iron castings, aluminum castings are preferred when weight reduction, heat dissipation, and good machinability are important.
JC Casting, as a dedicated aluminum casting factory, produces components suitable for precision, high-volume, and functional applications.
Features
Aluminum alloy casting is a highly versatile process. Its fluidity, low melting point and rapid heat transfer can result in shorter casting cycles and decreased production time. Besides it, the additional benefits including
- High strength-to-weight ratio
- Excellent corrosion resistance
- Outstanding thermal and electrical conductivity
- Complex Shapes Available
- Less Machining, Low Cost
Aluminum Casting Company, Process
JC Casting is an aluminum casting company in China. We have our own foundry and machining workshops.
For aluminum casting, there is not only one casting process for aluminum casting. Such as Aluminum die casting, Aluminum permanent mold casting, Aluminum sand casting (green sand and dry sand), Aluminum investment casting, Aluminum continuous casting, etc.
Aluminum Alloy Casting
Aluminum alloys contain a high percentage of aluminum alloyed with copper, magnesium, silicon, tin, manganese or zinc. They are lightweight and corrosion-resistant and are the alloy of choice for many aerospace applications due to these properties. Aluminum alloys can be strengthened through either heat treatment or cold-working processes, depending on the alloys.

Aluminum Casting Process
Casting aluminum is one typical method to get casting parts by pouring molten aluminum into a steel mold. The steel mold has to be precision processed to ensure that the cast piece gets a smooth and refined surface.
In order to discuss the aluminum casting process, it is necessary to examine the different methods. JC Casting can provide many processes customers would prefer.
- Die Casting: There are two types of die casting: low-pressure and high-pressure die casting.
- Sand Casting
- Investment Casting
- Permanent Mold Casting
- Centrifugal Casting

Aluminum Casting Alloys
Cast aluminum alloys Classification is developed by the Aluminum Association of the United States.
Each cast alloy is designated by a four-digit number. Here are eight different aluminum alloys.
The number is from one to eight. The first three numbers show the alloy with which aluminum has been combined.
