USBs are primarily made from a combination of materials, including plastic for the outer casing, metal for the connectors, and silicon for the internal circuitry. The plastic provides durability and protection, while the metal components ensure proper connectivity and conductivity. Additionally, the internal components often include various electronic materials like copper for wiring and semiconductor materials for data storage. Overall, these materials work together to create a functional and portable data transfer device.
