Anyone know how much 15lbs of scrap magnesium is worth?

Yep I always assume "refurbished" magnesium wheels = body filler = no. Sorry to hear this, could have been much worse if they failed, best of luck, with what's next wheel wise!

 

BC forged can make various offsets etc. Some nice options.

Is that a surface scratch or a crack? If just a surface scratch it could be filled by welding and resurfaced.

 

I wouldn't write them off yet. Mag can be welded (you can probably find someone in the old Porsche world, 911's had mag crankcases 1969-1977). Maybe it's just one rim.

 

Honestly that was my first thought--not to write off the other three.

 

Needless to say, Mg is scary stuff to work with when it comes to heat. Be very careful. It does make great pyrotechnic material, however. Just sayin'.

 

Like the guy at the tire shop said, "I can't patch your blow up doll anymore time for a new one"

 

That wheel is done, but as posted the other three might be good, damn that's a scary thing to hide,

Good thing you found it in the Shop and not at speed.

The bubbling paint is a common problem if Zinc Chromate is not the first primer re applied.

 

Not convinced this is a crack. It may be a casting anomaly because it is too irregular to be a crack. Cracks tend to be much more linear. The only real way to verify for sure is to X-ray the mag. If this was etched the etchant will preferable attack the high free energy grain boundaries first. Was this etched?

 

That almost looks like pitting rather than a crack possibly from scratch on the rim exposing the raw magnesium? I know when I refinished mine and removed all the old paint there was some decent pitting / corrosion.... Were these checked properly by a professional? I would double check first.

 

I would do a search on NDT (Non Destructive Testing) Services in your area.

Services to Consider would be X-Ray, Ultrasonic Testing and/or Eddy Current Testing.

 

Doesn't look like a crack to me. Try magnafluxing it. Very simple and cheap DIY process involving spray dye.

 

Those wheels were really bad for cracking. Some of those don't look like cracks but cracking is extremely common.

 

Almost looks like what we used to call a sodium crack back in the mag wheel days of the 60's. The wheel is scraped at one time letting something effect the scratched are propagating a score mark. Similar to scoring glass or a stone before splitting it.
I'm not sure of the percentage of mag in these wheels. I do remember salt killed them.
No I would not trust them, wall art

 

That's not a crack and I would almost back my own statement that that was a scratch that corroded exposed magnesium at some stage

 

That's not much better than a crack. May as well be crack.

 

Il take them off your hands if need be.. those cracks wont bother me at all.

 

Yuuup
