Differences of 7 series aluminum alloy sheet and 8 series aluminum alloy sheet for sale Haomei

What is the difference between the 7 series aluminum alloy sheet and the 8 series aluminum alloy sheet for sale? What are the 7 series aluminum alloy sheets and the 8 series aluminum alloy sheets made of? What can it be used to make? What properties do they have? Let's find out together today! And here are the differences of 7 series aluminum sheet and 8 series aluminum sheet for sale.

The main alloying element of the 7 series aluminum alloy sheet is zinc. Adding magnesium to the alloy containing 3%-75% zinc can form MgZn2 with a significant strengthening effect, which makes the heat treatment effect of the 7 series aluminum alloy far better than that of the aluminum-zinc binary alloy. Therefore, the 7 series aluminum alloy sheets produced are mostly used in aircraft manufacturing structures and other high-stress structures that require high strength and strong corrosion resistance. According to this situation, the 7 series aluminum alloy sheet has the following characteristics. First of all, the main alloying elements of 7 series superhard aluminum alloys are zinc, magnesium and copper. Its representative grades are 7050 and 7075. These aluminum sheets all have excellent heat treatment effects, ultra-high strength deformed aluminum alloy sheets, good plasticity after solid melt treatment, good mechanical properties, good wear resistance and fatigue resistance. However, their disadvantages are poor weldability, a tendency to stress corrosion and cracking, and the need for aluminum or other protective treatments. So we can also know what they are used for. 7 series aluminum alloy sheets are mainly used in aerospace equipment, and are also widely used in various machinery, molds and other processing fields.

Next, we will introduce the 8 series aluminum alloy sheet. The 8 series aluminum alloy plate belongs to aluminum-lithium alloy, and its main component is lithium. Because lithium is the lightest metal in nature, 8-series aluminum alloys are quite lightweight. And after adding lithium to the aluminum plate, it can effectively reduce the proportion of aluminum while ensuring the strength of the aluminum plate. Such properties make 8 series aluminum alloy sheets often used to make bottle caps and aluminum foils. Most of the 8 series aluminum alloy plates can be used to seal bottle caps, and can also be used in the form of aluminum foil for radiators, etc.
