6061 Aluminum Plate Quality Data Sheet/Chemistry Composition:

6061-T6 Aluminum Alloy Plate Mechanical Properties Standard：

Aluminium 6061 t4/t6 6061 t4 vs t6 hardness：

6061T6 is a state of artificial aging treatment after solid solution treatment, which gives 6061T6 high strength and hardness. It is commonly used in the manufacture of trucks, tower buildings, ships, trams, etc. 6061T4, on the other hand, is a state achieved through tensile treatment to eliminate residual stress after solution treatment. Its yield strength is approximately four times that of 6063, but its corrosion resistance and welding performance are poor.

Specifically, 6061T6 has higher strength and hardness after T6 treatment, making it suitable for applications that require high strength and hardness. 6061T4, on the other hand, although its strength and hardness are slightly lower after stress relief, in certain specific applications where stress relief is needed to avoid deformation, the T4 state is more suitable

2.What is the difference between 6061 and 6061 T6 aluminum?

6061 aluminum alloy is a commonly used aluminum alloy material with moderate strength and good welding performance. 6061-T6 is an aluminum alloy material that has undergone heat treatment and has higher strength and hardness. Among them, "T6" represents a specific heat treatment state, which improves the mechanical properties of the material through high-temperature solution treatment and artificial aging.

Due to special heat treatment, 6061-T6 has significantly improved tensile strength, yield strength, and hardness compared to 6061. This makes 6061-T6 more suitable for applications that require high strength and hardness.

6061 aluminum alloy is commonly used in applications where mechanical performance requirements are not particularly high, such as general industrial parts, building aluminum materials, etc., due to its good weldability and moderate strength. 6061-T6, due to its higher strength and hardness, is more commonly used in the manufacture of high-strength automotive components, aerospace structural components, etc.

Although 6061 and 6061-T6 have the same raw materials, there are differences in composition and state, mechanical properties, and application scenarios. When choosing to use, appropriate materials should be selected based on specific needs and usage environment.

In practical applications, in addition to considering the type and performance of materials, other factors such as cost, production process, and supply status also need to be considered. Therefore, when choosing to use aluminum alloy materials, various factors should be comprehensively considered to make a reasonable choice. At the same time, for the use of different materials, corresponding usage norms and operational requirements need to be followed to ensure safety and effectiveness.

3.What is the difference between natural and artificial aging aluminum?Artificial aging refers to a heat treatment method in which aluminum alloy sheets or profiles that have undergone two-stage quenching are placed in a constant temperature chamber at a certain temperature to achieve aging effect. Artificial aging will achieve the desired strength and toughness through heating within a certain period of time.

Natural aging refers to a treatment method in which aluminum alloy automatically ages to a certain degree at room temperature after being left for a period of time, and its strength reaches its highest value. Natural aging exposes aluminum alloy materials to high temperatures and humid environments in the natural environment, causing them to gradually age and achieve good strength and toughness after reaching a certain level
