The body skin is the main component of the automotive such as coach. There are three rectangular square holes on the top of the skin for installing safety windows, side doors and oil engine doors. The four corners cut off the gap for installing corner parts. Automotive aluminum sheet is required to be flat and free of defects such as warpage, scratches, bumps, etc.
It is forbidden to be used when the warpage of aluminum sheet within 1000mm is greater than 30mm. Since the warped board can be forced flat by the tooling during the bonding and foaming process, but the internal stress cannot be eliminated, there will be a hidden danger of skin debonding and bulging.
5052 aluminum sheet is used in the skin of a large new energy bus body. It is an aluminum-magnesium alloy with high strength, plasticity and corrosion resistance. 5052 alloy also contains a small amount of chromium.
The role of chromium is similar to that of manganese, which can improve the stress corrosion cracking resistance of the weld and reduce the tendency of welding cracks. These properties meet the corrosion resistance and fatigue strength requirements of bus body skin.
In addition to 5052 sheet, car aluminum is also widely used in other parts of automobiles, such as the application of 6061 aluminum plate on automobile/truck wheel hubs,wings. 5083 Aluminum sheet is often used to make gas storage tanks,etc.
Haomei Aluminum mainly have 5xxx and 6xxx automotive sheets like 5052, 5083, 5754, 6061, 6016, 6014,etc. They are widely sued for the interior and outside doors, hood panel, trunk,etc. Welcome to leave message below to inquire what you need.
