it's harder to make
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
no
aluminum is more durable than iron.
IRON STRONGER.....ALUMINUM LIGHTER.....IRON IS HEAVY.....ALUMINUM WILL BREAK EASIER THAN IRON
It depends on the alloy and temper of each material. Beryllium copper alloys are harder than the softest aluminum alloys, and high-strength aluminum alloys are harder than pure copper (which is quite soft). And almost every metal is harder than lead, except a few such as gold.
Yes, Absolutely......... Gold is softer than Iron... Gold becomes Harder because of other components that is being added like Silver and Copper. They add these components to add strength into the Jeweleries.
Aluminum has about 1/3 the density of iron, therefore a given volume of aluminum would weigh about 1/3 as much as the same amount of iron. So no, aluminum is not heavier than iron; far from it.
Aluminum is pretty hard; it is not as hard as steel, but it is harder than copper.
Iron is generally harder than bronze, but variations in chemistry or impurities can vary the hardness in both materials.
yes
