150HB
The hardness of 7075 aluminum alloy is typically 150HB, but the specific value depends on the heat treatment state.
T6 temper (most common): After solution treatment and aging, the hardness is approximately 150HB, with very high strength, commonly used in aerospace and mold making.
O temper (annealed): The material is softer, with the hardness reduced to approximately 60HB, offering better plasticity and easier machining.
Other tempers: Hardness fluctuates with the process; for example, T6 temper forgings requires a hardness of no less than 135HB.
This alloy belongs to the ultra-hard aluminum category, with a hardness approaching that of steel, and is one of the commercially available high-strength alloys.
It is worth noting that 7075 aluminum alloy not only has high hardness but also excellent mechanical properties and corrosion resistance. Its tensile strength is as high as 524MPa to 525MPa, and its yield strength is also quite excellent, making it widely used in aerospace, mold making, and other fields. Furthermore, 7075 aluminum alloy exhibits excellent machinability and high wear resistance, enabling it to maintain high precision and stability during manufacturing.
In practical applications, the hardness value of 7075 aluminum alloy is adjusted according to specific usage requirements and processing conditions. For example, in applications requiring higher hardness, its performance can be further improved by optimizing heat treatment processes or employing other strengthening methods. Meanwhile, due to its relatively affordable price and ease of processing, 7075 aluminum alloy is widely welcomed and used in many industrial sectors.
