The application of 7075 aluminum plate is actually quite wide, in addition to the aerospace field, in many industries have applications, some customers will ask us 7075 aluminum plate manufacturers, 7075 aluminum plate be used in the use of power cable?Here's the secret.

1, first of all, the corrosion resistance of 7075 aluminum plate is not too good, not as strong as the corrosion resistance of pure aluminum, mainly because 7075 aluminum plate added alloy elements such as magnesium, copper, zinc, so the corrosion resistance is slightly lower.

2. Secondly, the temperature resistance of 7075 aluminum plate is lower than that of copper, which is only 660℃. It will melt in a very short time and lose its conduction function, so it is not suitable for use as cable material.

3. Then the thermal expansion coefficient of 7075 aluminum plate is higher than that of pure aluminum. The high thermal expansion coefficient will lead to bad contact vicious circle, and the power supply is poor to the peak and valley, so the relative 7075 aluminum plate is not suitable.

4. In addition, 7075 aluminum plate is also easy to oxidize, and the formation of oxide film will also affect the conductive shock, which is not easy to conduct electricity.

Thus it can be seen that 7075 aluminum plate is not suitable for use in power cables. If you want to use it, it is recommended to use pure aluminum.

The above is the introduction about whether 7075 aluminum plate can be used in power cable. If you want to consult the price of 7075 aluminum plate, you can contact us.
