fusible alloy
[ˈfjuːzəbəl ˈælɔɪ]
nounpl: fusible alloys
liga fusível
1. A metallic mixture with a relatively low melting point, typically composed of metals such as bismuth, lead, tin, and cadmium, used in safety devices, soldering, and casting applications
The fusible alloy in the sprinkler system melts at 68°C to release water in case of fire.
A liga fusível no sistema de sprinkler derrete a 68°C para liberar água em caso de incêndio.
2. An alloy specifically engineered to melt at predetermined temperatures for automatic triggering of safety mechanisms
Engineers selected a fusible alloy with a melting point of 80°C for this thermal fuse application.
Os engenheiros selecionaram uma liga fusível com ponto de fusão de 80°C para esta aplicação de fusível térmico.
Fusible alloys are critical components in industrial safety systems, particularly in fire suppression sprinklers and electrical safety devices. The term is standardized across both Brazilian Portuguese and European Portuguese technical literature, reflecting the universal nature of industrial safety standards. In the USA, these alloys are extensively used in building codes and fire protection systems, making knowledge of this terminology important for engineers and safety professionals in both countries.
