Hardness of Common Aluminum Alloys
Aluminum alloys are generally softer than other metals, such as steel or titanium. However, the hardness of aluminum alloys can vary widely depending on the alloying elements present and the heat treatment process used.
The following tables provide a list of Brinell hardness (HB) values for common aluminum alloys.
All values are taken at room temperature (approximately 20°C or 68°F).
