The melting point of aluminum depends on its form and purity. In its pure form, aluminum has a melting point of approximately 660 degrees Celsius or 1220 degrees Fahrenheit. However, when alloyed with other metals, such as copper or magnesium, the melting point can change significantly. Copper-aluminum alloys can melt between 500–600°C (932–1112°F), while magnesium-aluminum alloys can melt between 600–700°C (1112–1292°F) . Aluminum oxides have even lower melting points than pure aluminum metal, starting to melt anywhere from 200–400°C.

It is important to note that nearly all applications for aluminum are as an alloy rather than a pure element, and depending on the composition of the alloy in question, this has the potential to reduce the melting temperature significantly relative to pure aluminum.

In summary, the melting point of aluminum is approximately 660 degrees Celsius or 1220 degrees Fahrenheit in its pure form, but it can vary significantly depending on the alloy and its composition.
