铝卷带属于纯铝卷系列其强度相对比较低，铝卷具有优良的延展性、成形性、焊接性和耐腐性；阳极氧化后可进一步提高耐腐性，铝卷同时获得美观的表面；但不可热处理强化。 纯铝卷系列根据较后两位阿拉伯数字来确定这个系列的较低含铝量，比如1100系列较后两位阿拉伯数字为00，铝卷 根据牌号命名原则，铝卷含铝量必须达到99.00%以上方为合格产品。我国的铝合金技术标准(GB/T3880-2006)中也明确规定1100含铝量达到99.0%。
Aluminum coil strip belongs to pure aluminium coil series, its strength is relatively low, and aluminium coil has excellent ductility, formability, weldability and corrosion resistance; corrosion resistance can be further improved after anodizing, while aluminium coil can obtain beautiful surface; but it can not be strengthened by heat treatment. Pure aluminium coil series determines the minimum aluminium content of this series according to the last two Arabic numbers, such as the last two Arabic numbers of 1100 series are 00, and aluminium coil according to the international brand naming principle, aluminium coil must reach 99.00% or more before it is qualified product. China's technical standard for aluminium alloy (GB/T3880-2006) also clearly stipulates that the aluminium content of 1100 can reach 99.0%.
Although we all know that the density of aluminium is 2.7, it refers to the density of 99.9% aluminium. The common aluminium coils on the market contain certain alloys, so the density is higher than 2.7, or less than 2.7. Today we will popularize the density of common aluminum sheets.
First of all, the most close to the density of aluminium coil, this series of aluminium plate is called pure aluminium plate, the density is 2.71. Represents the product is 106 0, other materials are basically default density is 2.71. In this series of products, the content of aluminium is more than 99%, which also contains manganese, silicon and other alloys, so the density is slightly higher than the density of aluminium.
The second is the second series. The representative product of this series is 2024. The density of the product is relatively high because of the high content of copper alloy, which is 2.78. The main reason is that the content of copper in the product reaches 3-4%, so the density is higher than that of ordinary pure aluminium.
The density of the three series is 2.73, mainly because there are manganese alloys in the inner, but the density of the five series aluminium sheet is relatively light, because the content of magnesium alloy in the five series aluminium coil is high, and the density of magnesium alloy is lower than that of aluminium. Usually, the density of the five series aluminium sheet is calculated according to the density of 2.68. There are magnesium alloy and silicon alloy in the 6-series aluminium sheet. The density of the two kinds of neutralized aluminium sheets is about 2.7.
These are the densities of several common aluminium coils. The results are not 2.7 as you might imagine. This is mainly related to the alloy content, because the density of aluminium is constant, but the density of internal alloy content is different. In order to get the exact weight, the theoretical formulas should be set according to different densities. Of course, although the density of the same series of aluminium coils is slightly different, the difference is not big.
