One of the main disadvantages of direct chill aluminum over continuous cast aluminum is that, since direct chill requires a fast freeze, it's more likely to form air pockets or trapped water. These can make for weaker and less durable parts. Another disadvantage of direct chill casting is that it has a smaller capacity than continuous cast ...Web
