👉 In the context of mathematics, a cupper (or "cup") is a type of metal alloy that contains copper and tin. It is often used as a base metal in the production of thin-walled parts for various industrial applications such as pipes, wires, gears, and bearings. Cuppers are typically composed of two main components: the copper and the tin. The copper component serves as the conductor through which electrical current flows, while the tin component acts as an insulator to prevent heat
