STEEL vs ALUMINUM vs TITANIUM Connecting Rods

Tensile strengts seem way too high. Steel usually has 500 to 700 MPa, in rare cases 900, but 1300 is way too high.

Great stuff lots of info!!! You forgot one thing for steal. Alot of the oem rods nowadays use powder metal centered processes better than cast not as good as forged but for the money quite good.

Thank you man, great information, super simplistic and understandable language so a guy like me can both understand and enjoy the video❤️❤️👌🙏

What's the best connecting rod for a street engine that revs 8000 or more RPMs and for having fun on the roads.

Man bun alert👎

So in conclusion, forged steel is the best all rounder.

My aluminum rods weighs more than my steel rods….

so basically forged steel is still the best for boosty bois

Me craming for an exam. "Steel connecting rods are paper clips"

De tungsteno es mas resistenente

so the best rod would be forged and then machined down to size

As a machinist (a real one, not some random operator), who machines titanium all the time (Ti6Al), its simple. Not a problem at all, in fact i enjoy machining it.

Never disappointed with your videos, appreciate and keep going 👍

What aluminum are you using that has 95 ksi of strength!! That does not exist, even Al-7065-t651 the highest grade aerospace grade aluminum only manages 83 ksi

Excellent explanation

fatigue happens below yield strength

seriously this site does a great job explaining things that even a simpleton like me can understand

so basically forged steel is the best for me

What about sealed titanium bearings can you go into higher tips without fear of ruining bearings?

..i'm sticking with steel..

how about artifical diamond rods.

this video is a market scam for steel rods

Good-vid and good-comments below .

in the US it's steel vs aluminum vs titanum. OR someone will make them into an alloy and call it stealtitium

Milling a forged rod would be the perfect rod, the compressed dense layers of steel cut to size and cleaned up would be the superman of rods. The Man of Steel rods, only forged and milled Titanium rods would be its kryptonite

There's a sweet spot to the amount of carbon that you want in the steel to increase the tenacity. To little will give you mild steel like an SAE 1010 who will be very ductile but have a low resistance to permanent deformation where as a 440c used for hard razor blade will be to brittle to resist to crack propagation. So a 4140 or a 4340 is in the sweat spot for the carbon contant. The same principle can be applied for the heat treatment. (benite to soft and martensite to brittle).

Forging creates strain hardening and therefore increases the tenacity of the part. A handmill can create micro-notches in the part acting like a crack instigator and therefore reducing the resistance to fatigue of a part.

Galling happened in my LS7. Glad you covered it

You could grow Ti-crystal connecting rods which would be stronger than forged steal but I think each rod would cast more than a range rover sport

would you be able to make a comparison between a light flywheel and a heavy flywheel, what would be the advantages and disadvantages.?

Not the manbun sharkeisha nooo

A titanium part can actually last forever depending on the crystal structure. Generally speaking any alloy that crystallizes in a body-centered cubic lattice can endure infinite load cycles (at least theoretically). Titanium crystallizes in a alpha-phase (hcp) or beta-phase (high-temperature bcc-phase). If you add enough elements to titanium which stabilize the beta phase (e.g. Cr, Mo, W, V, Nb) you can obtain a beta-alloy which can live forever. Another advantage of titanium is the extreme oxidation resistance which tool steel does not possess to this extent. Otherwise excellent video material

How come aluminum pistons last forever? They seem like they would receive more stress than rods and have much less cross sectional area in these high load regions (wrist pin, ringlands)

Thank you for your knowledge 💪🏽 USA 🇺🇸 USA 🇺🇸

Even thought I wont be using it. It is just what I need to know. All the pro's and con's I thought about nicely explained.
It would be nice if you can explain to me how to get rid of...say 4 dekades of my age.
I'd be delighted and I'd change my further life around my new gained knowledge. THX pal.
PS. Since you can't do that. At least it's a relieve to now knowing answers to my qestions. Sign in, bell, like and all of it 🖖
Greetings from Germany

So, if cnc rods and I assume other parts aren't as strong overall as forged rods but have certain qualities that are better than forged rods, then why don't you just forge a part slightly bigger than what you need and then mill it down?

Another great video. I don't know if you cover fluid dynamics but I would seriously enjoy a video on torque converters. The depth at which you cover rotating assemblies coupled with the still and animated visuals really aids in a deeper understanding.

Was reeatching this and noticed the "6% Alunumun" lol

The more I learn about steel the more amazing it is.

Thank you

What about cast iron rods?

The Chart was very informative

Damned titanium rods. I hate-em in my engine.

Back in late 1960 my uncle built race engine with aluminum rods before the build my uncle tried to talk the guy out of not using the aluminum rods but he didn't listen and the engine blew up. So I wouldn't use them in my engine either.

So what would be better than steel in your rods?

Steel is real.

This was a good Scientific explanation of the why and how. Seem to be worthy of a, University professor level lecture. Well done and an enjoyable broadcast. Give you a, 5 out of 5 star rating. Aloha & Mahalo. 🌺🌸🌴❤️🇺🇸
