2. Characteristics and Structure

Aluminum billets are produced through alloy aluminum casting processes, where the main elemental component is aluminum combined with other metals such as magnesium, manganese, silicon, copper, etc., to enhance the mechanical properties and strength of the product. The ratios of these components are adjusted according to specific application requirements to meet various product feature and quality standards.

Aluminum billets enable the production of products with complex shapes. Particularly, aluminum billets have smooth surfaces, high strength, good corrosion resistance, and environmental friendliness. Hence, aluminum billets find widespread applications in the construction and industrial sectors.

During the billet production process, aluminum is mixed with other elements such as silicon, copper, magnesium, manganese, etc., to form aluminum alloys with special properties. These alloys are divided into various series, including 3xxx, 4xxx, 5xxx, 6xxx, and 7xxx. Depending on the usage requirements, aluminum alloys used in billet production will have different characteristics and properties to meet various quality standards and requirements.

Billets are divided into various series, suitable for different applications in manufacturing industries.

3. Aluminum Billet Production Process

The aluminum billet production process is complex, requiring meticulousness in each stage. At Dinostar Aluminum factory, the aluminum billet production process consists of 7 steps carried out sequentially, from inspecting the raw materials to packaging and transportation. The specific steps are as follows:

  • Step 1: Raw Material Inspection

At this stage, samples of pure aluminum ingots are taken and inspected to ensure purity before proceeding to the next production steps.

  • Step 2: Melting

After meeting the initial standards, ingot raw materials are placed in a melting furnace at temperatures ranging from 660°C to 710°C. This stage transforms aluminum from solid to liquid form.

  • Step 3: Alloying

Liquid pure aluminum is mixed with elements such as Silicon, Magnesium, Manganese, Copper, Zinc, Chromium, etc., according to international alloy standards, to create various aluminum alloys to meet manufacturers’ requirements such as A6063, A6061, A6005, A6060, Series 7000, etc. Additionally, water samples are taken and analyzed multiple times during this stage to ensure absolute accuracy of the alloy composition.

  • Step 4: Casting

Liquid aluminum alloy is passed through a GBF system and poured into casting molds of predefined sizes and diameters. Subsequently, the aluminum billet bars undergo ultrasonic testing to detect and eliminate any products that do not meet the standards during the casting process.

  • Step 5: Cutting

The aluminum billet bars are cut into standard lengths of 5m8 or 6m or according to the requirements of each aluminum billet manufacturing unit.

  • Step 6: Homogenization

Aluminum billets are passed through a homogenizing furnace to enhance the physical properties and uniformity of chemical elements in the billet bars, while also improving the surface quality of the finished aluminum billet blanks.

  • Step 7: Quality Inspection, Packaging, and Transportation

This stage is crucial in determining whether the product is ready for the market. Physical and surface property inspections are conducted to ensure that the product meets the technical requirements before reaching the end-users. Products that do not meet the requirements will be rejected, while those that meet the quality standards will proceed to the packaging process and be delivered to customers.

Aluminum billets at the factory, once meeting quality standards, are packaged and transported to both domestic and international markets.

This process demands strict supervision and adherence to multiple inspection procedures according to international standards to ensure the quality of the aluminum billet production.

4. Characteristics of Aluminum Billet

Aluminum billet exhibits superior mechanical properties such as high hardness, corrosion resistance, tensile strength, and good shaping ability. Below are the prominent characteristics of the most commonly used aluminum billet alloy types:
