7075
aluminum sheet plate is a cold-treated forging alloy with high strength which is far better than mild steel. 7075
aluminum plate is one of the most powerful alloys for commercial use. With a compact structure and strong corrosion resistance, 7075
aluminum alloy is the best for aviation and marine panels. Its fine grain makes the sheet’s deep drilling performance better and the tool wear resistance is enhanced. Hardness can reach 90 ~ 120HBW. If hard anodizing is performed, the surface hardness can reach 350 HV or more; if electroless nickel-phosphorus alloy is applied, the surface hardness reaches 550 HV.<br></p>

Since the hardness of the 7075 <strong>
aluminum plate</strong> is almost the highest in the
aluminum plate family, the simple hardness test becomes one of the ways to judge whether an
aluminum plate is 7075. Since hardness and density are generally proportional, strategic density becomes one of the methods of judgment. The density of 7075
aluminum alloy is usually between 2.8 and 2.85. In actual production, 7075
aluminum alloy often needs to be cut and cut. In order to avoid the size being too small to be used, the actual size will be larger than the blank size. Therefore, the weighing is about 2.85 g/cm3, which is actually not because the density is wrong, and the second is because the actual size is larger than the size of the blank, which is a normal phenomenon. It can be seen that the 7075
aluminum alloy can not be judged 100% only by measuring the density. Another simple way is to have a 6061 plate smashed into a 7075 plate, and the damaged one is 6061. This method, however, is a waste of 6061
aluminum plate materials. The safest and most economical way proves to be material quality inspection.</p>

If you want to purchase <strong>7075
aluminum sheet plate</strong>, the top priority is to find a reliable supplier, or else even sample inspection cannot guarantee quality of the final products.</p>
