Recycled aluminum ingots, also known as remelted aluminum ingots, are made by melting and casting scrap aluminum or secondary aluminum materials into ingots for further processing and manufacturing various aluminum products. Remelted aluminum ingots are an essential raw material in the aluminum industry, widely used in producing aluminum alloy castings, extrusions, and sheet products.
Below are images of various specifications of recycled aluminum ingots:
Remelted aluminum ingots can be classified into various types based on their composition and application. The main categories include standard ingots and non-standard ingots.
Standard ingots include the following common types:
* ADC12 aluminum ingot:
+ Features: Good casting performance and mechanical properties, widely used in automotive parts, household appliances, and various castings.
+ Applications: Suitable for manufacturing engine blocks, transmission cases, motorcycle parts, and more.
* A380 aluminum ingot:
+ Features: Good casting performance, corrosion resistance, and mechanical properties, widely used in the automotive and construction industries.
+ Applications: Used for manufacturing automotive engine parts, transmission cases, electronic equipment casings, and more.
* A356 aluminum ingot:
+ Features: Excellent casting performance and mechanical properties, suitable for producing high-strength and high-toughness aluminum castings.
+ Applications: Commonly used in the automotive, aerospace, and industrial equipment sectors for high-performance components.
* 6061 aluminum ingot:
+ Features: Good mechanical properties, machinability, and corrosion resistance, suitable for a wide range of industrial applications.
+ Applications: Used for manufacturing structural components, building materials, and shipbuilding parts, among others.
* 6063 aluminum ingot:
+ Features: Good extrusion performance and surface treatment properties, widely used in producing extrusions and architectural materials.
+ Applications: Commonly used in door and window frames, pipes, radiators, and other products.
Non-standard ingots typically only constrain the aluminum content, without specifying other elements. For example, 95 aluminum ingot refers to a non-standard ingot with 95% aluminum content.
Recycled aluminum ingots typically come from factories with melting and processing capabilities for recycled aluminum.
The value of remelted aluminum ingots lies in:
1. Lower cost compared to electrolytic aluminum ingots.
2. Simpler processing pathways compared to electrolytic aluminum oxide. For example, using ADC12 as the raw material for recycled aluminum ingots can significantly reduce the need for adjusting elements, resulting in cost savings.
3. Energy efficiency and environmental benefits.
4. Flexibility in layout, without relying on ports, energy infrastructure, and other basic facilities.

Various aluminum processing enterprises.
Some small-scale recycled aluminum ingot manufacturers use small furnaces, often with capacities of only a few tons or even less than one ton. This can result in significant variations in elemental composition between ingots, affecting their usage value. Larger furnaces tend to produce ingots with more stable elemental compositions, which are more valuable.
