How to understand the heat state in aluminum alloy grades

How to understand the heat state in aluminum alloy grades? After different aluminum alloy grades, we can usually see a combination of letters and numbers, so what does this mean? In fact, this means different hot states of different aluminum alloy grades. Different hot states will bring different properties to aluminum alloys, so buyers must pay attention to understand its hot state. Then let's teach you how to see it today!

First, let's look at what the letters after the grade mean. In the case of 6063-T5 aluminum alloys, the "-" is usually followed by a letter, while they may be H or T, which is the refining symbol for the work-hardened state or the heat-treated state. "H" indicates the temperament symbol of non-heat-treated alloys and "T" indicates the temperament symbol of heat-treated alloys. The second digit after the letter indicates the alloy in which the main alloying element content or impurity content has been modified in the original alloy. For example, "0" indicates the original alloy, "1" indicates that the original alloy has been modified for the first time, and "2" indicates that the original alloy has been modified for the second time. The third and fourth digits, pure aluminum indicates the original alloy, and the alloy indicates the code of the individual alloy.

Aluminum alloy material. The main alloying elements are magnesium and silicon, which have excellent processing performance, excellent weldability, extrusion and plating, good corrosion resistance, toughness, easy polishing, coloring film, excellent anodizing effect, and are typical extrusion alloys. Aluminum alloy is widely used for its good plasticity, moderate heat treatment strength, good welding performance and gorgeous surface color after anodizing treatment.
