Chemical Composition According to BS EN 573-3 standard specification, the composition of 6005A aluminium is notable for containing relatively high amounts of silicon (Si) and magnesium (Mg). Silicon is used to increase strength, but at the expense of ductility. It also lowers the melting temperature and increases the fluidity of the alloy. Magnesium increases hardenability through heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion. Manganese and chromium have an anti-crystallisation effect.

Comparison of 6005 aluminum vs. 6005A aluminum alloy
Chemical composition
6005 aluminum alloy: With a higher silicon content, it has a lower melting point and enhanced extrusion performance. This high silicon content allows 6005 aluminum to be easily formed during production, particularly for complex profiles manufactured through extrusion processes.
6005A aluminum alloy: Compared to 6005, 6005A contains more chromium and manganese. The increase in chromium reduces the risk of stress corrosion cracking while improving the material's toughness. The addition of manganese further enhances its extrudability and strength, making 6005A aluminum superior in mechanical properties.
Mechanical properties
6005 aluminum: It has good extrudability, suitable for manufacturing medium-strength, simple structural components and profiles. While the increased silicon content aids extrusion, it does not significantly enhance strength or toughness, making 6005 aluminum suitable for applications with lower strength requirements.
6005A aluminum: The addition of manganese and chromium improves strength and toughness, giving it an advantage in certain high-strength applications. Its enhanced strength allows it to perform better under higher mechanical loads.
Corrosion resistance
6005 aluminum: It has good corrosion resistance, suitable for outdoor or corrosive environments, but its resistance to stress corrosion is slightly inferior to that of 6005A.
6005A aluminum: Due to the addition of chromium, 6005A exhibits better resistance to stress corrosion cracking, making it more durable in harsher environments. This results in greater stability over long-term use..
Welding performance
6005 aluminum and 6005A aluminum: Both have good welding performance and are easy to weld using standard operations, making them suitable for applications like building frames and machinery that require welding. However, the heat generated during welding can reduce the strength of both aluminum alloys, so this should be considered in the design process.
Bending performance
Both exhibit excellent bending performance, providing flexible shapes and structures for various applications. However, they are not suitable for applications that frequently experience overload or impacts, as this could lead to structural fatigue or damage.
Extrusion and complexity of shapes
6005 aluminum: While the high silicon content helps improve extrusion performance, it still faces challenges in producing thin-walled and complex shapes.
6005A aluminum: The addition of extra manganese enhances the extrusion performance of 6005A, but it also performs poorly in producing thin-walled, complex profiles.
Surface treatment and anodizing
6005 aluminum and 6005A aluminum: Both are well-suited for anodizing treatments, such as dyeing, hard coating, and coloring. Anodizing enhances their corrosion resistance and improves the aesthetic appeal of the surface treatment. In contrast, un-anodized aluminum alloys are more susceptible to environmental contaminants, and prolonged exposure may lead to corrosion.
