7075 T6 is a common 7075 aluminum alloy used in manufacturing and metalworking. Do you know what 7075 T6 aluminum alloy is, what properties it has and what applications it is used in? In this blog we will take a closer look at this popular aluminum alloy and explore its uses and properties.

7075 Aluminum Alloy:

7075 aluminum alloy is one of the strongest commercially available alloys and is also a cold-worked forging alloy with higher strength, far better than mild steel. The alloy has a compact structure and high corrosion resistance, making it ideal for use in marine sheet and aerospace applications.

7075 T6 Aluminum Alloy:

7075-T6 aluminum alloy is a high-quality aluminum alloy material produced by heat treatment pre-stretching process, and its composition is mainly zinc, magnesium and copper. This alloy has good strength, corrosion resistance and mechanical properties, and has excellent thermal conductivity, which can shorten the molding time and improve work efficiency. 7075-T6 aluminum alloy is widely used in aviation, aerospace, military, industrial and other fields, for the manufacture of aircraft structures, high-strength mechanical parts, military special products, mold processing, mechanical equipment, tooling fixtures, etc.

Manufacturing Process:

T6 treatment refers to the artificial aging treatment after solution treatment, which can improve the strength and hardness of the alloy.

7075-T6 aluminum alloy has good plasticity after solution treatment, and the heat treatment strengthening effect is particularly good, with high strength below 150 degrees, and particularly good low temperature strength, poor welding performance, and stress corrosion cracking tendency. The anti-SCC performance can be improved through two-stage aging. All oversized and over-thick 7075 aluminum plates are all detected by ultrasonic, which can ensure that there are no trachoma and impurities.

Performance:

7075 T6 aluminum alloy has good oxidation resistance, and the general corrosion resistance except for stress corrosion is similar to that of 2024 alloy. In the T6 state, it is sensitive to stress corrosion cracking in the short transverse direction, while the T73 and T76 states can greatly improve the stress corrosion resistance of the alloy.

From the perspective of physical properties, the specific heat capacity of 7075 T6 aluminum alloy is 796J/(kg·°C), the density is 2.8g/cm3, the resistivity at room temperature is 57.4nΩ·m, and the conductivity is related to the material state, and the size of T6 material is 17.7MS/m~20.6MS/m.

Applications:

  1. Aerospace & Shipbuilding: Due to its excellent properties, it is an ideal material for the manufacture of aircraft structures and other highly stressed structural parts, such as upper and lower wing siding and trusses for aircraft.
  2. Precision machining and mold making: It is also commonly used in precision machining and mold making because of its fine grains, which makes for excellent deep drilling performance and enhanced tool wear resistance.
  3. Chemical industry: This alloy can be used to make chemical parts and structural parts, such as pipes, vessels, valves, pumps, furnaces, etc.
  4. In addition, it has good resistance to general corrosion except stress corrosion, so it can also be used in other industrial fields.
