Can we use pure aluminum to make coins or medals that will last longer and look better over time?

While pure aluminum is lightweight and corrosion-resistant, it is not typically used for making coins or medals due to its low melting point and softness. Coins and medals often require materials that are harder and more durable to withstand wear and tear over time. Additionally, pure aluminum is less visually appealing as it does not have the luster or reflective qualities of other metals like silver or gold. Alloys are generally preferred for coinage and medals because they offer better durability, resistance to wear, and can be tailored to have specific properties like hardness and resistance to corrosion.
