JC Casting is a Customize aluminum casting company with ISO Certificate in China. We focus on aluminum Casting production in different casting processes: Investment casting, sand casting, die casting.

What is Aluminum Casting?

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.

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 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.

Precision Investment Casting for Aluminum Alloys 

Engineered Precision Casting Company, Inc. provides aluminum alloy casting for prototype to large-scale production runs. We use a master heat system to strictly control our metal inventory and have experience pouring over 75 ferrous and non-ferrous air-melt alloys. For precision investment casting applications requiring additional finishing and services, we also offer heat treatment, non-destructive testing, and more.

Our specialty is casting complex parts for demanding applications. We have extensive experience casting thin-walled and multi-cored aluminum projects for various aerospace customers, utilizing our extensive casting history dating back 70+ years. Contact us to discuss your investment casting project or for assistance selecting the appropriate alloy for your application.

Aluminum Alloy Casting Materials

Aluminum alloys are used for investment casting a wide range of components including those for aircrafts and engines including fittings, housings, levers, valves, impellers, and more. Our aluminum alloy casting material options include: 

• A-356 Casting Alloy: contains silicon, magnesium, iron and zinc. It provides excellent corrosion resistance and good weldability and can be heat treated to improve strength.
• A-357 Casting Alloy: is composed of silicon, beryllium, iron, copper, magnesium, titanium, zinc and manganese. It provides high strength and corrosion resistance and can be heat treated to improve the strength characteristics.
• C-355 Casting Alloy: contains silicon, iron, copper, manganese, magnesium, zinc and titanium. It offers excellent corrosion resistance and has good weldability.
• F-357 Casting Alloy: composed of silicon, iron, copper, magnesium, titanium, zinc and manganese. It provides high strength and can be heat treated to improve strength characteristics.

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.
