Aluminum melts at 1,220° F, I doubt electric stovetops get that hot.

"For example, pure aluminum metal melts at 660°C (1220°F). However, when you alloy it 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).

Additionally, aluminum oxides have even lower melting points than pure aluminum metal. They can start to melt anywhere from 200-400°C (392-752°F). As you can see, understanding the point at which aluminum begins to melt depends largely on what form it takes."

But, steel loses 1/2 it's strength far lower than the melting point, assuming something similar here... how hot can an electric stovetop get?

"This is because the uppermost setting can result in the stove top reaching extremely high temperatures, anywhere between 500 and 750 degrees Fahrenheit."

"Just like steel, aluminum alloys become weaker as the service temperature rises. But aluminum melts at only about 1,260 degrees, so it loses about half of its strength by the time it reaches 600 degrees."

And there it is...
