What Is DC Aluminum Circle?

 

The aluminum circle products can be divided into DC aluminum circle and CC aluminum circle according to the different processing method. DC aluminum circle (Direct Chill Casting Aluminum Discs) is a kind of aluminum alloy casting product, which is usually used to manufacture various aluminum products, such as pots and pans, electronic product shells, lamps and lanterns, packaging materials, etc. DC casting is an aluminum alloy casting process, which is characterized by casting the molten aluminum into semi-finished products in the form of flakes or discs by means of the direct cooling method.

DC aluminum circle is a high quality product compared with CC aluminum circle, is has features as following:
- Excellent physical properties:
DC aluminum circle has good mechanical properties and corrosion resistance, can be used in wet, acidic or alkaline environment.
- Uniform organizational structure:
Due to the rapid cooling of the aluminum liquid in the casting process, the formation of aluminum circles have a dense structure, fine grains and uniform distribution of grain structure, reducing the defects of aluminum alloy, improve the mechanical properties of the material and processing properties, such as strength and toughness.
- Good surface quality:
DC aluminum circles have a smooth surface with good appearance, which is suitable for subsequent processing and surface treatment.
- Machinability:
This kind of aluminum circle is easy to be machined, such as cutting, stamping, forming, etc., suitable for use in a variety of manufacturing processes.
- Lightweight and high strength: Aluminum circle is lighter than many other metal materials, but with higher strength, so it is widely used in occasions where light weight and high strength are required.
- Corrosion resistance: Aluminum circle has good corrosion resistance.

The production process of DC aluminum circle usually includes the following steps:
- Smelting: Melting the aluminum alloy raw material to form aluminum liquid.
- Casting: The molten aluminum liquid is injected into the mold and solidified by cooling.
- Cooling: During the casting process, the liquid aluminum is cooled directly by a stream of cooling water to form aluminum circles.
- Cutting and processing: The cast aluminum circles are cut to the required size for subsequent surface treatment and processing.
Among them, casting is a key step, which determines the organizational structure and performance of aluminum circles. In the casting process, the casting speed, cooling intensity and other parameters need to be strictly controlled to obtain high-quality aluminum circles.

DC aluminum circles are widely used in the following fields:
- Kitchenware: such as aluminum pots, aluminum plates and other cooking utensils.
- Electronic products: for the shells and heat sinks of electronic components.
- Lighting equipment: such as reflectors and housings for lamps.
- Packaging materials: for food packaging, pharmaceutical packaging, etc.

DC aluminum circle is a high-performance aluminum alloy material with excellent physical properties and processing performance, which is widely used in many industries. Its manufacturing process ensures product quality and consistency, and it is an important raw material for many aluminum products.
