2024-11-20

7075 T651 aluminum plate is a high-performance aluminum alloy plate, widely recognized for its excellent physical and mechanical properties. It is widely used in aerospace, military, automotive and other fields.

The main properties of 7075 t651 aluminum plate are as follows:
1. Alloy composition
7075 aluminum alloy is mainly composed of the following elements:
Aluminum (Al) - major component
Zinc (Zn) - 5.1% - 6.1%
Magnesium (Mg) - 2.1% - 2.9
Copper (Cu) - 1.2% - 2.0
Silicon (Si), iron (Fe), manganese (Mn), titanium (Ti) and other trace elements.

2. 7075 T651 aluminum plate has the following characteristics:
- High strength: 7075 aluminum alloy is one of the highest strength aluminum alloys, tensile strength can reach more than 570 MPa, yield strength of 503 MPa, much higher than many other types of aluminum alloys.
- Good Mechanical Properties: In addition to high strength, it has good wear resistance and anodizing properties.
- Heat treatment and pre-stretching: The T651 temper indicates that this material has undergone a specific heat treatment process as well as a pre-stretching treatment, which helps to reduce internal stresses and improves the stability of the material and its dimensional stability after machining.
- Good Corrosion Resistance: Although 7075 aluminum alloy is not as corrosion resistant as some other aluminum alloys, its corrosion resistance can be significantly improved by surface treatments such as anodizing.
- Weldability:The weldability of 7075 aluminum alloy is relatively poor and welding is usually not recommended. If welding is required, it is recommended that special welding materials be used.
- Machinability:7075 T651 aluminum plate performs well in the machining process, but due to its high hardness, processing requires the use of appropriate tools and techniques to avoid rapid tool wear.

3. Application areas
7075-T651 aluminum plate is widely used in areas that require high strength materials due to its excellent performance, such as:
- Aerospace: used for aircraft structural components such as wing beams, fuselage frames, etc.
- Mold manufacturing: suitable for making molds that need to withstand high pressure and abrasion.
- Mechanical equipment: used to make parts that require high strength and good mechanical properties.
- Sporting goods: e.g. high-end bicycle frames, skis, which need to be lightweight while maintaining high strength.
- Structural components for the automotive industry
- Military equipment
- Ships and other heavy equipment

Despite its superior performance, 7075 T651 aluminium plate has some limitations, such as unsuitable for welding, which may lead to a decline in material properties and poor corrosion resistance. Therefore, comprehensive consideration needs to be made when selecting the material according to specific application scenarios. And 7075 t651 aluminum plate should be stored in a dry, ventilated environment to avoid contact with corrosive substances and handled with care to prevent scratches and damage.

In conclusion, 7075 T651 aluminum plate is an excellent aluminum alloy material for a wide range of applications that require high strength and good mechanical properties. If you have specific application needs, we recommend contacting a professional aluminum supplier like Haomei for more detailed information and technical support.
