Ro-ràdh saidheans mòr-chòrdte puing leaghaidh alùmanum
Dè a th’ ann am puing leaghaidh?
Is e an ìre leaghaidh an teòthachd aig a bheil stuth cruaidh ag atharrachadh bho chruaidh gu leaghan aig àm teasachaidh, ‘s e sin, an teòthachd aig a bheil nì a’ tòiseachadh a’ leaghadh. Aig an teòthachd seo, faodaidh staid chruaidh agus leaghan stuth a bhith beò, agus atharraichidh meud agus dùmhlachd an stuth. Tha puing leaghaidh na sheilbh corporra de stuth, agus tha puingean leaghaidh eadar-dhealaichte aig diofar stuthan.
Dè an ìre leaghaidh airson alùmanum?
Dè an ìre leaghaidh alùmanum? Alùmanum (Al) tha e aotrom, meatailt fìor ghiùlain agus ductile le puing leaghaidh alùmanum gu ìre ìosal, a tha a’ dèanamh alùmanum puing leaghaidh ìosal air a chleachdadh gu farsaing ann an gnìomhachas agus beatha làitheil. Tha a 1000-8000 sreath, and the melting point of pure aluminum is about 660.3°C (1216.54° F.). This means that at an aluminum melting point temperature of 660.3°C, pure aluminum begins to change from solid to liquid.
Do all aluminum alloys have the same melting point?
Among many aluminum alloy series, among 1xxx-8xxx aluminum metals, 1000 series is pure aluminum alloy, and other series have many other small amounts of metal components added. Will there be any difference in the melting point of aluminum?

| 2000 series melt point of aluminum | 2024 | 500~700 | 932~1292 |
| 3000 series melt point of aluminum
(Tha an 3000 series aluminum has a relatively low melting point due to the addition of a higher magnesium element, agus a’ taisbeanadh deagh fheartan plastachd agus giullachd.) |
