I would like to hear the takes of people that actually know what the fukk they are talking about like 88 or mikey.

you referenced "galvanic corrosion" before, not reaction. Backtrack much?

Then you went off on some tangent about FE something or other, but I quit trying to follow you down that rabbit hole or keep up with moving goal posts.

Again, I'm not a metallurgist but have a basic understanding that there is a fundamental difference between steel and aluminum.

Aluminum does not corrode. They don't do "regular" checks "regularly" on aircraft for corrosion as you so eloquently stated. Oh, and you wrote that those supposed inspections were "expensive".

F-150 owners will not have to worry about corrosion.

Their "military" grade aluminum is 5052 H-38 and/or 6061 T6... basically silicon with more or less manganese and copper added with more or less tempering/quenching involved.

Steel is carbon based and the hardness/durability thereof has to do with how much further work is done to it after it's molted. It can be hot rolled (cheaper) and then cold rolled. It can be annealed, heat treated, stress relieved or pickled and oiled... many processes to get the final product, including galvanizing which you dropped your $0.02 and pants about

Had enough? I have.

Actually, they do corrosion checks on aircraft on a regular set schedule. We even have "Corrosion Control" departments in the maintenance departments in the Navy. Heck, when I was one of the Maintenance dept. officer's they sent us to corrosion control school. I guess they wanted us to know something since we were in charge of the troops that did the work. Maybe inspections are not so common in civilian aviation. It's a pretty big deal when flying low over salt water.

yeah, whatever you say then. They've been flying B-52's for 60 years and the least of their maintenance problems is galvanic corrosion of "dissimilar" metals.

Metal fatigue, maybe, but I'd guess those JP-7 engines are of more concern.

Do B-52's fly low over the ocean most of the time?

Dammit, AP, put the bottle down. You and I obviously just made this shit up in our domes as metallurgy wagon just told us that aluminum doesn't corrode. you do make a good point about how the maintenance procedures for a B-52 flying out of south dakota might be a little different from an F-14 flying out of well, the ocean, pretty much. Everything of the flight deck gets a pretty regular salt water shower. No worries though for ford, as their trucks will never be exposed to salt.

Wags,

Nice job with all the numbers and cold/hot rolled explanations, but your original points, claiming that oxidation is not corrosion or whatever the fukk you were babbling about is bullshit. And it doesn't matter if you call it galvanic reaction or galvanic corrosion. Both are accurate. You, not so much.

Now when is ford going to make the Mustang aluminum? That could actually make some sort of sense.

Aren't you a Navy guy?

I assume (although I have no idea) that Navy ships use sacrificial anode blocks to stave off corrosion.

I know that when people 'round these parts moor an aluminum boat in slat/brackish water, they use sacrificial anodes (zinc), which cause galvanic corrosion, which requires a flow of direct current.


Pretty standard boating shit.

Yes, a Navy guy.

As for anode blocks, they work well in a water heater and maybe even boats. My experience with this topic is with F-14s and other carrier based aircraft. Prolly no good place to hang enough of them to do much good. And if there was, it would still be dead weight. This is why Navy squadrons have entire departments dedicated to finding/repairing such damage. Remember, they are doing it with our great grandkids (and the chinese)'s money. So, that isn't a concern.

I'll spell it out again for you. The two terms are mutually exclusive, they are not comparable nor are they metaphors. Pick up a fucking dictionary.

And it doesn't matter if you call it galvanic reaction or galvanic corrosion. Both are accurate.

I didn't call it that. You did while trying to backtrack your way out of looking like a dumbass for the umpteenth time. Neither term is accurate when describing oxidation of aluminum, you brain dead fucking moron.

Define "use"

Not a bad idea.

ACF-50 and lots of of it keeps the corrosion at bye.

I hate it when that happens. :brad:

I stand by my take that aluminum doesn't corrode, but you know what?

I'm having a bad day.

Without even doing any research...

Ever heard of that "fiberglass" stuff? They put resin on... fibers.

Hmm... I'm trying to remember where they used to get fiber in the old days?

Raisin Bran? I slice up rusty banana's in mine.

Yep, I'm in 'damage control' mode.

As I said I don't know if the hemp panels made it on a car and yes the panels from the picture of him with an axe were 7% hemp, according to your link, but he did experiment with higher hemp percentages and the Kestrel is being made today with hemp panels. I'm not sure where that leaves us except to say Ford could do a lot better than using Al which was my original point.

That didn't help any.

I've had bad days too. It is not a good reason to be an illiterate fukking maroon.

Aluminum does oxidize.

Oxidation is the most common form of corrosion, according to the dictionary you recommend others read.

Is aluminum more resistant to corrosion than CRS? Yes, I believe it is, but, as I said earlier, it does open up a different can of corrosive worms, that being galvanic reaction. Now, I don't claim to be as smart as the engineers at Ford. I am sure they have read the dictionary as well. But, I could see it being an issue.

That being said, if someone want to give me a brand new al lou minnie um F-two fity extended cab, 4x4, I'll take it.

Just thought of another reason to not make pickup beds out of aluminum.

Ever pull a bed off a pickup? I could do my ranger in about 15-20 minutes. It is stupid easy.

Not sure what Al is bringing a pound at the scrap man this week, but, I think it is a little better than 50 cents a pound.

I can see tweakers lifting these fukking things right out of driveways. I will bet that a tweaker with LiIon impact gun (my favorite battery powered toy out there) could have a bed off in 5 minutes.

Pretty simple fix to that problem.


The scrap man has to pay for the metal via a check mailed to the sellers address on their DL or to the company address. The instant caysh is no longer an option for someone looking for their next high. The legit companies love it because the money is traceable and shows up in the central office instead of each worker having to bring in cash at the end of the day.

This has cut down on copper theft in areas where it has been implemented. .

They did that in Oregon several years ago. There's definitely less guard rails and statues going missing.

Actually, ferrous scrap they can still pay cash, non-ferrous (I believe over a certain dollar amount), they mail you a check.

smackaholic wrote:Aluminum does oxidize.

We found something we agree on. :golfclaps:

Like I wrote before, it's not always a bad thing. In fact, we purposely "oxidize" concrete forms after they come off the welding lines. It's called "pre-seasoning" and customers pay extra for it. It's a patented process. If I told you exactly how it's done, I'd have to kill you.

Concrete doesn't like raw aluminum. Bad chemical reactions occur. The concrete sticks to the forms and the walls have worm holes... like your infamous, warped foundation does.

That said, when the tarped 5052 sheet and 6061 extrusions roll in on flatbeds, we won't unload if it's raining. Water causes oxidation and can't be welded for shit.
