Aluminum Billet
Aluminum alloy billet is semi-finished aluminum products produced through continuous casting or direct cold casting processes, typically with a round cross-section and elongated shapes. They are the fundamental raw material for the entire aluminum processing industry, and aluminum billets can be further processed into profiles, tubes, bars, and other engineered products.
We offer a comprehensive portfolio of alloys across all major series (2xxx, 3xxx, 5xxx, 6xxx, and 7xxx), each tailored to specific downstream applications. Whether your requirements are high conductivity, marine-grade corrosion resistance, or aerospace-grade strength, selecting the right aluminum billet alloy is the first and most critical step in the manufacturing chain.
Our aluminum billet conform to international standards such as ASTM, EN, and ISO. We offer various specifications to meet different application needs and can customize cuts upon request.

HSTF Aluminum Billets Manufacturing Process
| Process | Details |
| Continuous Casting | HSTF’s continuous casting process involves continuously pouring molten aluminum into a water-cooled mold, achieving rapid and uniform solidification. The billets produced by this method have fine grains and consistent dimensions, making them ideal for high-volume production. It is particularly suitable for industries such as aerospace and automotive, where material uniformity and high precision are critical. |
| Direct Chill Casting | In direct chill casting, molten aluminum is poured into a preheated mold and rapidly cooled by water quenching or natural cooling. This simple and cost-effective process is ideal for applications requiring high-quality microstructures and faster production speeds. It is widely used in industries such as construction and consumer electronics, ensuring material purity while meeting customized needs. |
| Semi-Continuous Casting | HSTF’s semi-continuous casting process combines the advantages of continuous and intermittent casting. Through segmented production, it provides enhanced dimensional control and uniformity of internal structure. This method is particularly suitable for producing large-diameter billets or billets made of special alloys, providing reliable quality for a wide range of industrial applications, including heavy equipment and high-load structural components. |
