Expansion: because metals of the same kind of durability are cheaper than other types of materials and are more cost-effective to manufacture, they use more metals than plastics. Most of the instruments are used for measurement and use, so the outer casing needs to use a more durable material, and metal materials are a good choice. The player housing made of metal material is more durable than the wooden player; the metal casing is more plastic. The appearance can be diversified, and the appearance of the powder is varied. (It can be powder plating, painted, anodized). The metal casing can be recycled and reused.
