What is the cylinder head made out of?

A cylinder head made of cast-iron is more durable and less expensive. However, cast-iron is heavy and provides a lesser efficiency in dissipating heat. For this reason, some manufacturers prefer using cylinder heads made of aluminum. These cylinder heads are much lighter than cast-iron cylinder heads.

Subsequently, one may also ask, how much does it cost to repair a cylinder head?

Average Repair Cost. The cost to repair a cracked cylinder varies between different model cars. The average minimum cost you can expect to pay is $500, but with parts and labor costs it could go up to about $1,000. If your car is still under warranty then you should be able to get these costs covered by your dealer.

What is the most common cause of warpage in an aluminum cylinder head?

Why are cylinder heads made of Aluminium?

Thus cylinder heads are generally produced by gravity or low-pressure die casting. But even if the engine block is cast iron, the cylinder head is normally made of aluminium as it allows a more rapid extraction of the combustion heat compared to grey iron.
