Menene ma'anar narkewa don aluminum?

Menene ma'anar narkewar aluminum? Goron ruwa (Taimakon al m) mai nauyi ne, sosai conductive da ductile karfe tare da in mun gwada da low aluminum narkewa batu, wanda ke sanya ƙarancin narkewar aluminum da ake amfani da shi sosai a masana'antu da rayuwar yau da kullun. Aluminum karfe yana da a 1000-8000 jerin, kuma wurin narkewar tsantsar aluminum yana da kusan 660.3°C (1216.54° F). Wannan yana nufin cewa a ma'aunin narkewar aluminum na 660.3°C, tsantsar aluminum ya fara canzawa daga m zuwa ruwa.
