1) Adding carbon to iron gives strength to the iron metal and it makes it more useful.
2) Despite gold’s desirable properties, it does have one significant drawback. It is soft, which means it wears easily. By mixing gold with other metals, or alloying it, gold is made stronger, which makes it durable enough to wear more often without experiencing wear. A variety of metals are commonly used to alloy gold, including silver, copper, nickel, iron, zinc, tin, manganese, cadmium, and titanium.
