someone said it was one of the genres of metal in a answer to my question but I don't know what it is!
Well I can think of a number of them, though probably not all ! You must first find out about the characteristics of the metal, type of metal,- as a number of things are classified as metal , - such as steel, aluminum, copper, alloys, like brass nickel etc. Then you have tensil-strength, - which is the hardness of the material, - as working the material (such as stretching, bending,) in order to get the material formed like a (car fender or a bowl for instance). You will also need to know how to prevent oxidation (called rust or corrosion), and what primer/paints required for different metals. Also joining different metals, welding etc. So you can see that you need to learn a lot!
