Aluminum Square Bar
Aluminum square bar is a basic extruded profile with a symmetrical square cross-section. Their simple and predictable geometry ensures excellent stability and ease of measurement, cutting, joining, and processing, thereby improving efficiency in workshops and production lines. The square cross-section provides high torsional stiffness and offers multiple planes for easy welding, installation, or surface finishing.
HSTF aluminum square bars are made from a full range of alloys, from the highly conductive 1000 series to the ultra-high strength 7000 series, and can be customized to specific needs, from decorative strips to high-load-bearing structural frames.

Containing zinc element, heat-treatable, it belongs to superhard aluminum alloy and is used in high-strength applications such as aerospace, military industry, and molds.
2024 Aluminium Square Bar
It features high strength and good heat resistance, but its corrosion resistance is relatively poor, often requiring anodizing or aluminum cladding for protection. The industry relies on this material mainly for producing high-load parts such as aircraft structural components, rivets, and truck wheel hubs, and it stands as one of the most widely used alloys in duralumin.
5083 Aluminium Square Bar
High-strength, corrosion-resistant aluminum alloy. Its most prominent feature is its exceptional corrosion resistance, particularly in marine environments, hence it is often referred to as “rust-resistant aluminum” or “marine aluminum.” It is widely used in shipbuilding, automobile bodies, pressure vessels, and structural components requiring good weldability.
6061 Aluminum Square Bar
6061 square bars combine excellent strength, corrosion resistance, and good machinability. The square cross-section offers unique advantages in applications requiring equilateral sections and precise dimensions, making it ideal for manufacturing structural components, shafts, pins, connectors, and machined parts with extremely high requirements for uniformity and strength.
6063 Aluminum Square Bar
This alloy earns the titles “architectural aluminum” or “window and door aluminum” because it offers excellent extrusion properties, a high surface finish, and easy anodizing. Designers and builders select it for its good weldability, plasticity, and processability, making it a staple in building doors and windows, curtain walls, decorative materials, and various industrial profiles.
6082 Aluminium Square Bar
It is a medium-strength, highly corrosion-resistant aluminum alloy material. Its most significant characteristic is its excellent overall performance, possessing good weldability, corrosion resistance, and machinability, and a strength higher than 6063. This material is widely used in transportation (such as automotive and ship structural components), machinery manufacturing, and building structures.
7075 Aluminum Square Bar
7075 aluminum square bars are known as “aerospace aluminum” or “super-hard aluminum.” Its most prominent characteristic is its extremely high strength (approaching or exceeding that of many steels), but its corrosion resistance is relatively poor, often requiring surface treatment. This material is widely used in aerospace, mold manufacturing, and high-load structural components.
