Copper refers to a copper alloy with a high zinc content. Generally speaking, copper alloys with a zinc content between 5% and 45% can be called red copper. The main components of copper are copper and zinc, but other alloying elements such as tin, aluminum, silicon, etc. are usually added. Compared with ordinary brass, copper has higher strength, toughness and corrosion resistance. Due to its good processing performance and beautiful color, red copper is widely used in handicrafts, decorations, musical instruments, building materials and other fields. At the same time, copper also has good electrical and thermal conductivity, so it is also used in the manufacture of electronic components, wires and heat sinks.
