Copper Unveiled: A Visual Exploration of Mining Techniques
There are a few reasons why copper wire is not commonly used as a fuse wire: 1. Conductivity: Copper is a very good conductor of electricity, which means that it does not offer much resistance to the flow of current. This means that a copper wire would have to be very thin to provide enough resistance to act as a fuse. However, a very thin wire would be more susceptible to damage and breakage than a thicker wire. 2. Melting point: The purpose of a fuse is to protect electrical equipment from damage caused by excessive current flow. When the current exceeds a certain threshold, the fuse wire melts and breaks the circuit, protecting the equipment. Copper has a relatively high melting point compared to other materials used for fuse wires, such as silver or tin. This means that a copper wire would require more current to melt, which could result in the equipment being damaged before the fuse wire breaks. 3. Availability: While copper is a widely used material in electrical systems, it is not typically used as a fuse wire. This means that there are other more readily available materials that are better suited for use as fuse wires. Overall, while copper is a useful material for many aspects of electrical systems, it is not an ideal material for use as a fuse wire due to its low resistance and high melting point Export of Copper scrap (http://nopm.cc/) Reception of Copper scrap
