I'm fairly sure you could find someone who would drill the damage out, weld it up and grind it smooth. I'm not saying that's safe but it could be done.

Why would you want a new rim under warranty? A NAIL went through the rim. How does that happen and how weak and soft are those rims? I'd rather get new rims that are impervious to nails, ie decent normal rims.

I'm not a machinist or metallurgist, but I would think that would be a freak occurrence, and completely explainable by the fact that steel/iron nails can go through a lot with enough force. Basically, if you don't want heavy all-steel rims, you're going to have to deal with the fact that steel will be harder than your rim's metal.

Titanium is lighter than most steels and aluminiums for the same performance.

That REALLY depends on the alloy of aluminum and titanium e: and what metric of performance you're using too I guess

I would hazard a guess that a titanium wheel with the same weight and performance of a magnesium wheel would be so expensive that even a Formula 1 team would think twice about the cost. High performance titanium alloys are fantastically expensive (and often very difficult to work with). Considering there are already a few out there, you're far more likely to see carbon fiber wheels become mainstream before anything else.

At the same time, you know they've tried doing it and if it offered some type of advantage it'd be in use. I can't imagine a team with a half a billion dollar budget a year would leave something on the table, especially since F1 bans composite wheels. I know CF wheels for motorcycles are somewhat common with the bling people, but they seem to be mostly banned by racing orgs due to questionable longevity.

Material choice is a complicated issue. When it comes to wheels, you're basically looking at the trade-off between light-weight vs strength vs. cost (basic material cost and fabrication cost). Roughly, you can put the three ideas on a triangle with each property on a vertex. Obviously, steel wheels sit somewhere close to the line between strength and cost. Aluminium obviously sits somewhere away from that line. As for titanium and magnesium, what you might find is that (for various considerations I'm not familiar with and can't guess at), the benefits of titanium over magnesium is too much overshadowed by cost, and thus you have no titanium wheels. Or, perhaps there are other issues with titanium that are not experienced by magnesium (for example, ease of fabrication) that really kills the idea.

How much force would that have taken to happen? Here's the friction plate from my old VW Polo, this happened 200 miles from home. I could have driven it, but I had breakdown cover with return from anywhere on it, so I opted for a comfortable coach ride instead. Falken fucked around with this message at 20:43 on Sep 5, 2013 |

Could it be that the nail was so perfectly positioned, and steadily held, that the revolutions of the wheel gave it a number of poundings. I've never before considered what it would take to hammer a nail through an alloy rim, but I'd wager it could be done, given the nail didn't bend first.

totalnewbie posted:Titanium is lighter than most steels and aluminiums for the same performance. No. The density per tensile strength of 6Al-4V vs a high strength wrought aluminum like 7075 is about the same. That Ti alloy is 60% more dense than 7075. When you add in safety factors the aluminum design will usually be slightly lighter unless you're designing for very high cycle fatigue where its possible the titanium will be slightly lighter only through very good design. MrChips posted:I would hazard a guess that a titanium wheel with the same weight and performance of a magnesium wheel would be so expensive that even a Formula 1 team would think twice about the cost. High performance titanium alloys are fantastically expensive (and often very difficult to work with). Titanium isn't THAT expensive. Ceramic composites are more expensive for sure when you add in manufacturing cost and they dont blink at new brake discs and NDT every couple of races or every race. Titanium brakes would be way cheaper (and shittier) bolind posted:Could it be that the nail was so perfectly positioned, and steadily held, that the revolutions of the wheel gave it a number of poundings. Ive penetrated a ford ranger aluminum alloy with a 12 gauge slug. if that nail was in the corner of a board and got ripped out upon penetrating the wheel it wouldn't surprise me in the least.

Most. Of course there are high-strength steels and aluminiums that beat titanium, but they are expensive and I'm not sure necessary for this application. Do you happen to know what alloys are used for wheels? I really don't; maybe they do use something like a 7075. Also, did you say high-cycle fatigue? On a WHEEL? :P InitialDave posted:I really need to start a business selling people car components made out of completely inappropriate but exotic-sounding material for five times what would be considered reasonable.

High strength aluminum that I am talking about are your cheap (relative to titanium) common wrought alloys. I am not talking about MMCs or anything exotic. For castings, 356. For billet wheels it will vary manufacturer to manufacturer, I'm betting most are plain ol' 6061/2024/7075. Nidhg00670000 posted:Plebs.
