鋁卷的密度是多少

鋁卷帶屬于純鋁卷系列其強度相對比較低,鋁卷具有優良的延展性、成形性、焊接性和耐腐性;陽極氧化后可進一步提高耐腐性,鋁卷同時獲得美觀的表面;但不可熱處理強化。 純鋁卷系列根據較后兩位阿拉伯數字來確定這個系列的較低含鋁量,比如1100系列較后兩位阿拉伯數字為00,鋁卷 根據牌號命名原則,鋁卷含鋁量必須達到99.00%以上方為合格產品。我國的鋁合金技術標準(GB/T3880-2006)中也明確規定1100含鋁量達到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%.
雖然大家都知道鋁的密度是2.7,但是這是指的含鋁量為99.9%的鋁的密度。而在市場上常見的鋁卷都是含有一定合金的,所以密度或大于2.7,或小于2.7。我們今天就普及一下常見鋁板的密度。
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.
首先說的是較接近鋁密度的鋁卷,該系列鋁板稱為純鋁板,密度為2.71.代表產品為1060,其它幾種材質基本上也默認為密度為2.71.在該系列產品中鋁含量都超過99%以上,其中還含有錳、硅等合金,所以密度稍微高于鋁的密度。
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.
其次是2系,該系列代表產品是2024,銅合金含量高所以密度也比較大,在2.78.主要是因為該產品內部銅含量達到了3-4%之間,所以密度要高于普通純鋁。
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.
3系的密度為2.73,主要是因為內部含有錳合金,5系鋁板的密度比較輕,因為5系鋁卷內部鎂合金含量高,而鎂合金的密度要低于鋁的密度,通常5系鋁板按照2.68密度來計算。6系鋁板內部含有鎂合金和硅合金,兩種中和后密度基本上在2.7附近。
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.

以上是幾種常見鋁卷的密度,結果并不像大家想象中的都是2.7,這主要也和合金含量有關,因為鋁的密度是恒定的,但是內部合金含量的密度不同。在理論計算式要按照不同的密度來套取公式才能得到準確的重量,當然雖然相同系列的鋁卷密度稍微有一點差距,但是差距不大
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.
