A alloy is a mixture or solid solution of two metals or a metal and a non metal. Mixtures of metals, any metals typically when one or more are molten.
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.
