Morphology

fusible + metal

The phrase is directly compositional: 'fusible' means able to be melted and 'metal' denotes a metallic substance, so a learner who knows both words can infer it denotes a metal that melts. The specific technical sense (a low‑melting alloy used for soldering or safety devices) is a straightforward, language‑neutral extension of that composition, so it is transparent to B1 learners.

Etymology

Fusible metal comes from a simple idea: it is metal made to be fusible — that is, to 'melt' easily. People put small pieces of this metal in pipe joints or in sprinkler plugs so they will melt at a 'low melting point' to join pipes or start a safety device, and that is why the phrase means a metal used for soldering and safety devices.
