Amalgamate and fuse both join things into one, with a difference in how completely. Amalgamate is to merge several things — especially organizations — into one combined body, where the parts often stay traceable. Fuse is to join things into one by melting them together, so the seam vanishes and they become inseparable. Amalgamate combines under one name; fuse welds into one mass.
Both make one thing, but fuse goes to the point of no return. Amalgamate, from amalgam (a mercury alloy), merges separate bodies into one whole — the formal word for companies and councils, whose old parts often remain visible inside the new body. Fuse, from Latin fundere 'to pour, melt', joins things by melting them together until there is no seam and no going back — two metals, two genres, two ideas welded into one. Two firms amalgamate into one company; a welder fuses two plates into a single sheet. One combines; the other melts into one.
amalgamate
To amalgamate is to combine several distinct things into a single larger whole — most often companies, institutions, or groups. The word comes from amalgam, an alloy of mercury with another metal, and it keeps that flavour: the parts bond into one body but often stay recognizable within it, the way stones stay visible in a wall. When firms amalgamate they dissolve into a new combined entity. It is a formal word, a close cousin of merge and consolidate, and the quiet opposite of forces that disperse.
fuse
To fuse is to join two things into one by melting them together, so completely that the boundary is gone — metals fuse under heat, and by extension genres, ideas, and cultures fuse into something new. From the Latin fundere 'to pour or melt'. The same spelling names a very different noun: a fuse is the thin wire in a circuit that melts and breaks when the current runs too high. Where two edges coalesce under heat they fuse; unlike things that merely diverge, what is fused cannot be pulled apart.

Ask how complete and how permanent the union is. Amalgamate merges bodies into one but leaves the parts faintly visible — firms under one name. Fuse melts the parts together until the seam is gone and they cannot be separated — two plates welded into one sheet. If bodies combine under one name, that is amalgamate; if things melt into a single inseparable mass, they fuse.
amalgamate

fuse

- iiThe band fuses jazz and folk into one sound.
- iiiIn the sun's core, hydrogen nuclei fuse into helium.
Fuse is more physical and more total than amalgamate: it involves melting (or the image of it) and leaves no seam, whereas an amalgamation lets the old parts show. Fuse ranges from welding and nuclear physics to the arts (a band fuses styles); amalgamate stays institutional. Note the noun fusion, common in science and cooking, has no exact echo in amalgamation's narrower sense.
A precise pair for science, arts and business writing. Fuse suits things joined by melting or by an image of it — metals, atoms, musical styles ('a sound that fuses jazz and folk', 'hydrogen fuses into helium') — and stresses a total, seamless union. Amalgamate is the formal, institutional word for organizations merging into one body. Examiners reward the fit: fusion for a complete melding, amalgamation for a corporate or administrative merger. The nouns, fusion and amalgamation, both raise the register.
