Copper and zinc combine to form brass. The colour and corrosion resistance of brass make it a common material for jewellery and craft projects. Cutting both tight corners and straight lines on sheet brass requires a jeweller's saw. A jeweller's saw contains three adjustment screws that provide the tension required for the saw's thin blade to cut through a brass sheet.
