Question: 1 / 400

Which metal alloy has a lower melting point compared to steel?

Platinum

Steel

Aluminum

Aluminum is the correct answer because it has a melting point that is significantly lower than that of steel. The melting point of aluminum is approximately 660 degrees Celsius (1220 degrees Fahrenheit), whereas steel's melting point typically ranges between 1370 to 1510 degrees Celsius (2500 to 2750 degrees Fahrenheit), depending on the specific alloy composition. This attribute of aluminum makes it advantageous in applications where lower weight and ease of handling are essential, as it can be formed and shaped at lower temperatures compared to steel.

In contrast, platinum has an extremely high melting point of about 1770 degrees Celsius (3218 degrees Fahrenheit), making it unsuitable for comparison with steel in this context. The melting points of other options, such as titanium, also exceed that of aluminum, with titanium melting at approximately 1668 degrees Celsius (3034 degrees Fahrenheit). Therefore, aluminum stands out as the metal alloy with a lower melting point relative to steel.
