IIRC, the best material for engine blocks, especially for high performance production cars that are expected to be reliable, is CGI (Compacted Graphite Iron), an iron alloy used for NASCAR engines which are known for engines with even higher mean piston speeds than F-1 engines and cover longer race distances. It's not cheap though.

[@MrD3000]

Those engines are usually also used only once, since they're worn out after a single race.

[@TheDude50447]

The main factor for rpms is weight. So if that iron is lighter than the alternatives for the same strength then yes. And while I dont know what F1 engines are made out of if its the best material shouldnt they use it as well?

Ford Racing used to sell the 6 cylinder NASCAR blocks decades ago. All custom stuff.

There is no simple answer. Its like asking what tire is best. It all depends on situation and purpose. Probably the most important factor is choice. Its great to have the option of selecting what material block you want to use for your application.

[@michaelbenardo5695]

It depends on what you are using it for. For conventional passenger cars and trucks, cast iron is the best, as it is more durable and more resistant to damage. For racing, aluminum is better because it is so light. It can mean the difference between winning for a few inches or coming in second by a few inches. In racing, that is all the difference in the world.

Aluminum blocks typically handle engine overheating conditions better than iron blocks. This is because aluminum has better thermal conductivity, meaning it can transfer heat away from the engine more efficiently than iron. Additionally, aluminum tends to have a lower coefficient of expansion, which reduces the risk of warping or cracking under extreme temperatures compared to iron. As a result, aluminum blocks are often preferred in high-performance engines or applications where heat management is crucial.

[@foch3]

They manage heat not overheating. Everyone knows aluminum heads warp easily when overheated. The most powerful engines per cubic inch, Top Fuel dragster are cast iron.

[@ColinKarvinen]

Ive thought my aluminum block was inferior to iron for a long time because of strength, but I’d much rather have better cooling.

[@newfie-dean5803]

@@foch3 Having aluminum heads with an aluminum block is better in terms of overall heat dissipation and thermal expansion compatibility. This setup ensures similar thermal expansion characteristics, potentially reducing the risk of warping or damage during overheating. And cast iron blocks are predominantly used in the most powerful drag cars because of cast iron’s superior strength allowing it to take the repeated stress imposed on the engine without cracking or warping it.

[@johncunningham4820]

Rubbish ! Aluminium is MUCH more prone to warpage if overheated . Yes it carries heat away quicker , but once pushed too far the Engine is a Boat Anchor .

[@greebj]

That's all so wrong. Aluminium has better thermal conductivity (W/mK) than iron but the higher thermal expansion means more damage occurs when it overheats. BMW E39 is a famous example of what happens when you pair a cooling system made of plastic parts that wear and fail and kill alloy engine headgaskets and warp blocks. With enough lazy owners who don't do preventative maintenance and run it till it fails, leaving heaps of cheap and available parts at wreckers for the rest of us, bless their hearts

A lighter aluminum engine block hasn't reduced overall vehicle weight as other options filled weight loss. There has not been much fleet fuel economy improvement with aluminum engine blocks as they produce more power using same or more fuel. Most aluminum blocks use the open deck design that gives upper cylinder less support allowing head gasket failure. Let's not talk about older seasoned aluminum blocks that have head bolt thread failures. There is a difference between 25,000 psi and 15,000 psi material strength. At this point, aluminum is likely the cheaper OEM option. An ordinary car is not a race car nor an airplane, but it's marketing.

ya iron blocks expand more evenly during overheating events. less prone to warping. ive never heard of someone resurfacing an iron head. heck ive never heard of someone having to do a headgasket on an iron block. there are dozens of early 2000s honda civics on every fb marketplace that have over heating issues and are just a time bomb waiting to cost the next lucky teenager 1800$ to try and fix the head/gasket. iron blocks also run hotter due to lower thermal conductivity, most tuners think you want to run the engine as cool as possible to make peak power, but for fuel economy having a hotter engine is better for fuel mixing and thermodynamic efficiency. think about it, they didnt invent compressed graphite head gaskets until aluminum blocks became mainstream. naturally asperated iron blocks with the right transmission will go 400-500k miles easy until something weird breaks. most aluminium heads ive had crap out at around 200-280k miles, usually due to over heating issues and the eventual headgasket failure. you can run iron blocks at higher compression ratios which gives more fuel economy. for hwy driving, and not going over a mountain, your weight is a negligible factor for fuel economy. epa cares more about in town fuel economy, thats why everything has an AL head now. plus they dont last as long which car mfg love.

Iron block for boost, aluminum for n/a...

[@dogukancil5128]

This video is misleading. 1. An Iron block is harder to repair sure, but you almost never need to because iron blocks have a nigh infinite fatigue life, meaning if you don't push them to the breaking point, you can use them forever, which is not the case for aluminum. Aluminum has a finite fatigue life, meaning every time you use it, its lifespan decreases. You don't need to push it to the breaking point, instead the breaking point comes to it in a sense. 2. Most aluminum blocks are not rebuildable. You can't just "resleeve" an aluminum block. In fact, a lot of shops will flat out refuse to resleeve your block. You wanna know why? BECAUSE THEY BREAK. You can literally split an Aluminium block like you would firewood during the resleeving process. The irony is that the sleeves are most often made of cast iron, albeit very thin. 3. Aluminum expands, A LOT. Your engine gets hot, so your bore gets larger. Your piston was sealing the bore tight when it was cold, but now that it is hot, there is a Grand Canyon between the piston rings and the cylinder wall. You don't want that. Because your exhaust will leak into your crankcase and contaminate your oil, meaning you have to change it more often. Plus, a lot of manufacturers make the pistons wider to account for thermal expansion. But now the pistons are too tight when it is cold, so your car doesn't start, or it starts but damages your sleeves each time. 4. Aluminum gets warped. Your engine block has coolant passages and areas around those passages get the best cooling while other areas are cooled less. Hot parts expand more, cooler parts expand less, and your block gets warped. When it does, it might no longer seal against the cylinder head, as a result, coolant leaks into your oil or your head gasket blows. 5. Aluminum strips. While a minor annoyance, aluminum threads get stripped because you have to torque them so high to ensure a good seal. I am pretty sure I have some other things to say but I'm sleepy.

[@myloveforlife200]

Imagine diamond block 😂

[@edongbato9234]

Does Aluminum blocks burns oil?

[@MikeM-oq9pz]

No, aluminum blocks do not "burn oil' if proper oil change procedures are followed. It all depends on the piston ring material as some newer engines have piston rings that have low tension in the cylinder block, and these can cause oil burning problems at higher mileage moreso than the aluminum.

[@synthyawylder3297]

Whether the block be iron or aluminum, I would never, ever, want an engine with the head(s) being a different material than the block - iron block & aluminum head, or aluminum block & iron head - since the 2 metals expand & contract at different rates & amounts, blown head gaskets are a perpetual problem. Another is less well known: that of corrosion, the result of 2 different metals being bolted to each other, & especially with heat & a working fluid passing between & through them. Aluminum engine blocks are also less tolerant of over-torquing, & special attention must be observed, when considering the different torquing specifications during servicing or rebuilding the 2 different types of engines. Iron engines will tend to tolerate being overheated, better than aluminum engines; more often than not, if an aluminum engine suffers a catastrophic cooling system failure, it's best to simply replace it, as everything will likely be warped & lose its temper. Most of my experience working on engines, has been in the marine field, & those engines lead a hard life, usually being operated at full throttle & load - both iron & aluminum engines will fail, but for heavy duty & long life, especially for diesels, iron is best; for outboard engines, aluminum is best due to its inherent lighter weight. I've never seen engines with the 2 different metals making up the block & head(s) have as long & relatively trouble-free life, as those made of 1 or the other single metals. Aluminum also has an additional weakness, that of its reaction to the hot water-glycol mix, if there's ever a blown head gasket, & the coolant finding its way into the cylinder(s), &/ into the crankcase - aluminum is more reactive than iron. Ofc, the bearing materials of either type of engine, simply don't tolerate that water-glycol mix at all! Air-cooled engines do have their advantages & their place in certain applications.
