I found a guy that said he will make me some Aluminum SFC's and Aluminum LCA's for $250. but wouldn't aluminum rust?

 

I dont think aluminum is strong enough. Most use steel or chrome moly.

 

Aluminum will not rust, it can corrode.

I'd pass on the Aluminum SFC's. But Aluminum is just fine for LCA's (if done properly).

 

trackbird,

Rust is corrosion, but I know what you ment.
Aluminum will form a thin layer of rust (kinda whitish/greenish) but it wont rust through like steel or other iron ore derivatives.

I agreee with the others here that aluminum isnt strong enough for SFC use.

Rust is corrosion, but all corrosion isn't rust. Non ferrous metals don't rust, they corrode. But anyway.....

 

Rust is oxidation. Aluminum will not rust.

 

Yes I agree...pass on the aluminum sub frames. I really doubt they would be strong enough. As for the alum. LCA's thats up to you. If the guy isnt experienced and hasnt tested them just make sure they will be strong enough too. It all depends on his design.

I have boxed style weld in subs and steel tubular LCA's...works great for me. I have $250 in my set up brand new.

 

Aluminum SFCs would need to be made of solid bar stock and properly hardened after manufacture to approach the level of strength that a properly made steel set has.

Hardly worth the effort in my opinion.

There are many commonly avilabale processes to stop the corrosion of AL when exposed to the elements. Powder coating and anodizing are two that immediately come to mind. Paint also is an effective method of corrosion prevention.

 

Yes, rust is oxidation. Aluminum will oxidize. It just wont disintegrate like an iron ore derivative. Almost anything will oxidize. Oxidation just means that the object has combined with oxygen.

Anyway, this is getting off-topic.

Oxidation:

1. The combination of a substance with oxygen.
2. A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased.

Easy pneumonic for oxidation is OIL, Oxidation Is Loss of electrons.

Corrosion:

1. [*]
2. [*]

Rust:

1. Any of various powdery or scaly reddish-brown or reddish-yellow hydrated ferric oxides formed on iron and iron-containing materials by low-temperature oxidation in the presence of water.
2. Any of various metallic coatings, especially oxides, formed by corrosion.
3. A stain or coating resembling iron rust.
4. Deterioration, as of ability, resulting from inactivity or neglect.

Sorry for the dictionary post. Just helps to have the terms and their definitions sometimes

 

Thanks Levi!

Thanks for the post.

I dont want to sound rude...but,I knew that already. I have taken a few years of chemistry and usually scored near the top of the class.

Were you trying to prove or disprove what I said?
It seems like you proved what I said.

I dont mean to sound rude or an a-hole.

Cannibal and Trackbird:

Are you guys moderators? I don't remember. You guys post on here a lot and know what you are talking about.

Sorry to the thread-starter (Zero_FactiX) for the side-track.
