Refinement type

Refinement type is a way of categorizing materials to make it easier to understand what they are made of. Different materials have different qualities, so they can be split into groups called refinement types. For example, steel, aluminium, and copper are all metal refinement types. Each of those metals have different properties, so when you need a metal for a project, you can look at the different refinement types to see which one will work the best.
