这关键区别在合金和铝之间是合金是由混合两种或更多不同的化学物质形成的物质元素而铝是一种化学元素,我们可以在地壳上找到作为一个化学元素metal.
Aluminum is a metallic element with a silvery white appearance that is found in abundance in earth’s crust. Though making up almost 8% of the earth’s crust, it does not occur naturally as a free metal as it is chemically too reactive. On the other hand, an alloy is a substance that is consisting of several chemical elements. Aluminum has a wide range of applications in producing alloys because when we are converting metal into an alloy, it enhances the properties of the metal. Therefore, it becomes more useful to use the alloy rather than the individual metal.

什么是合金?
合金是一种物质,我们将几种化学元素结合起来以增强金属的性能。对于合金的生产,我们可以将两种或多个金属或金属和其他化学元件组合在一起。无论哪种方式,它都会形成不纯净的物质,因为合金中有几个成分。我们称其为“混合”。它保留并增强金属的特性。但是,这不是不纯净的金属,因为我们通过在受控条件下添加组件并以提供理想性能的定义量产生合金。具体而言,合金中的一个或多个组件必须是金属。
产生合金的最常见和最古老的技术是将金属在其熔点之外加热以将其他成分溶解到熔融液体中。即使溶质的熔点远大于此温度,这也是可能的。但是,这种技术对金属和具有很高熔点的元素没有用。例如。铁和碳。在那里,我们应该使用固态扩散的技术来制造合金。否则,我们可以使用具有所有组件在其气态状态下涉及合金过程的方法。
类型
在合金生产过程中,有两种主要类型的合金,即替代合金和间质合金。这两种形式根据合金形成的机制彼此不同。替代合金通过原子交换机制形成,而间质合金通过间质机制形成。简而言之,当成分的原子的大小相对相似时,就会发生原子交换机制,而当一种类型的原子比其他类型的原子小得多时,就会发生间质机理。
什么是铝?
Aluminum is a chemical element having the atomic number 13 and chemical symbol Al. It appears as a silvery-white, soft metal. Moroever, it is nonmagnetic and highly ductile. It is abundant on earth (8% of earth’s crust). This metal is highly chemically reactive. Therefore, it is difficult to find native specimens of aluminum. Especially, this metal has a low density. Thus, is lightweight and it is able to resist corrosion via forming an oxide layer on its surface.
关于这种金属的一些化学事实如下:
- 化学符号为al。
- 原子数为13。
- 电子配置为[NE] 3S23p1
- Standard atomic weight is 26.98.
- 在室温和压力下,它处于固体状态
- 熔点为660.32°C
- 沸点为2470°C
- 最稳定的氧化状态为+3。
当考虑到铝的合金,象征性的al alloying components are copper, magnesium, zinc, silicon and tin. There are two forms of aluminum alloys as casting alloys and wrought alloys. We can divide both these groups into two groups as heat-treatable and non-heat-treatable aluminum alloys. However, about 85% of the useful aluminum alloys are wrought forms.
合金和铝有什么区别?
Aluminum is a chemical element while an alloy is a mixture of several chemical elements. Hence, the key difference between alloy and aluminum is that an alloy is a substance formed from mixing two or more different chemical elements whereas aluminum is a chemical element that we can find on earth’s crust as a metal. In its pure form, aluminum has no use because of its low抗拉强度but finds extensive use when its alloys are made by adding elements such as zinc, manganese, copper, and magnesium.
摘要 - 合金vs铝
铝是一种金属,我们可以在地壳上发现丰富的金属。另一方面,合金是一种通过混合两个或更多不同元素而形成的物质。合金和铝之间的关键区别在于,合金是由混合两个或更多不同的化学元件混合而形成的物质,而铝是一种化学元素,我们可以在地壳上作为金属找到它。
