Common Aluminum Alloy Hardness Chart: Find Your Perfect Match

The table below provides typical Vickers hardness values measured with a Tianxing W-20 Vickers hardness tester for nearly 400 different grades of aluminum alloy materials with different heat treatment processes.

The Vickers hardness values in the table are actual measured typical hardness values of various aluminum alloy materials and are not used as the basis for whether the material is qualified. The hardness qualification values for various materials should refer to the corresponding product technical specifications. For example, it is stipulated in the national standard GB 5237.1 “Aluminum Alloy Building Profiles Part 1: Base Material” that the Vickers hardness value of 6063-T5 should not be less than 8HW, and the Vickers hardness value of 6063A-T5 should not be less than 10HW.

The Brinell hardness, Vickers hardness, Rockwell hardness, and Barcol hardness are for reference only and cannot be used for conversion. If conversion is required, it is recommended to use the hardness conversion table of the American standard ASTM E140.
