That’s why you hear the two terms used interchangeably or synonymously with each other. They perform what is effectively the same function.
Which is better iron block or aluminum?
Because iron is more rigid than aluminum, it won’t deflect and distort as much under high cylinder pressures. Modern aluminum blocks are pretty strong, but a properly built iron block is still ultimately going to be stronger, and that strength offers some benefits that might be less obvious.
Can you make an engine out of aluminum?
An aluminum internal combustion engine is an internal combustion engine made mostly from aluminum metal alloys. Aluminum offers lighter weight at the expense of strength, hardness and often cost. However, with care it can be substituted for many of the components and is widely used.
Are aluminum blocks worth it?
The major advantage of aluminum blocks are lightness, can tolerate flex more under high hp without breaking compared to an iron block and they can be repaired.
Are aluminum engine blocks better?
Aluminum makes for lighter and more fuel-efficient engines. But the weight savings of aluminum can be enormous. A four-cylinder aluminum block weighs about 50 pounds less than the same block made of iron. That savings allows 50 pounds to be trimmed elsewhere from the car.
