Aluminum and aluminum alloys have distinct properties. Pure aluminum is a soft, lightweight metal with good thermal and electrical conductivity. It is highly reflective and resistant to corrosion. Aluminum alloys, on the other hand, are made by combining aluminum with other elements such as copper, magnesium, or silicon to enhance its strength, durability, and resistance to heat and wear. These alloys are stronger and more versatile than pure aluminum, making them suitable for a wide range of applications, from aerospace to construction.
