Is real gold hard or soft?
Although it is very strong, gold is the most malleable of all metals. Pure gold is too soft to withstand the stresses of everyday wear, so it is combined with different alloys to give it strength and durability. These alloys include metals like silver, copper, nickel, and zinc.
How soft is pure gold?
