Mixture; Metal; Element; Crystal. In its scientific usage, the term metal means a metallic element. An alloy is a mixture or solid solution composed of a metal and another element. But in everyday language, we often use the word metal to describe what an alloy is. That is because a mixture of metallic elements is called an alloy. Iron is a metal element. Steel is a mixture of iron with other elements such as carbon, nickel, chromium, etc. and so is an alloy. An alloy is a mixture of either pure or relatively pure chemical elements, forming an impure substance retaining the characteristics of a metal. Alloy constituents are usually measured by mass.
An alloy is a homogeneous mixture of two or more elements, at least one of which is a metal, where the resulting material has metallic properties. For example steel is an alloy made up mainly from iron with a small amount of carbon (to make it harder), manganese (to make it strong) and chromium (to prevent rusting).n a mixture, the substances that make up the mixture: are not in a fixed ratio. Imagine, for example, that you have 250 ml of water and you add sand to the water. It doesn't matter whether you add 20 g, 40 g, 100 g or any other mass of sand to the water; it will still be called a mixture of sand and water.
