What is Aluminium?
铝是具有原子数字13和化学符号的化学元件。它看起来像是银色的柔软金属。而且,这是nonmagneticand highlyductile. It is abundant on earth (8% of the earth’s crust). This metal is highly chemically reactive. Therefore, it is difficult to find native specimens of aluminium. Especially, this metal has a low density. Thus, it is lightweight and is able to resist corrosion by forming an oxide layer on its surface.
The electron configuration of aluminium is [Ne] 3s23p1,and its standard atomic weight is about 26.98. it exists as a solid at room temperature and pressure conditions. The melting point of this metal is 660.32 °C, and its boiling point is 2470 °C. Moreover, the most common oxidation state of aluminium is +3.
When considering the alloys of aluminium, the typical alloying components are copper, magnesium, zinc, silicon, and tin. There are two forms of aluminium alloys; they arecasting alloys and wrought alloys. We can divide these groups into two groups: heat-treatable and non-heat-treatable aluminium alloys. However, about 85% of the useful aluminium alloys are wrought forms.
什么是铜?
Copper is a chemical element having the chemical symbol Cu and atomic number 29. It is a d block element. Moreover, it is a metal and has a red-orange metallic luster. It is one of few metals that has a natural color other than grey or silver. This metal is known for its softness,malleability, ductility, and high thermal and electrical conductivity. These properties arise due to its chemical nature, the presence of one s-orbital electron on top of filled d-electron shells.
该金属的标准原子量为63.54。该金属在化学元素周期表的第11组和第4个周期中。电子配置为[AR] 3D10 4S1。除此之外,该金属还属于过渡金属类别。因此,它在其最外面的轨道中具有一个未配对的电子。除此之外,这种金属在标准温度和压力下处于固态。熔点和沸点分别为1084.62°C和2562°C。此外,该金属最常见的氧化态是+2。但是还有其他一些氧化态。-2,+1,+3和+4。
Copper does not react with water, but it reacts with oxygen in the air to form a copper oxide layer, which appears in brown-black colour. This layer can prevent the metal from rusting. Moreover, this metal tarnishes when exposed to sulfur-containing compounds. The major uses of this metal include producing electrical wires, roofing, plumbing, industrial machinery, etc. More importantly, copper is often used as a pure metal rather than in alloy forms.
