The thermal fuse market encompasses temperature protection devices, also known as thermal links or thermal cutoffs (TCO), which serve as safety devices protecting electrical product components from overheating conditions. The industry upstream involves non-ferrous metals, electronic ceramics, and other raw materials. Thermal fuses primarily consist of three components including the fusible element, outer shell, and bracket, with the fusible element being the critical component controlling the fusing characteristics. Fusible element materials are classified into low melting point and high melting point categories. Low melting point materials such as lead and lead alloys have low melting points that easily fuse, but due to their high electrical resistance, the fusible element cross-sectional size is larger, producing more metal vapor when fusing, making them suitable only for low breaking capacity fuses. High melting point materials such as copper and silver have higher melting points and are less prone to fusing, but due to their lower electrical resistance, they can be manufactured with smaller cross-sectional sizes than low melting point fusible elements, producing less metal vapor when fusing, making them suitable for high breaking capacity fuses.
