Powder coatihg wheel hubs, other parts

Got a '78 CR250. Anyone powder coat the wheel hubs? Also thinking about coating the fork bottoms and the triple tree (if I can get that bottom bearing off). Any down side? Heard something about aluminum changing structure with high heat but I don't know if that applies to these parts. To tell the truth I'm not sure what metal is used for these parts but they're not magnetic.

Thanks,
Frank

Your powdercoater should know the safe max temp for aluminum and magnesium alloys.
I don't know it it is still the case, but at one time the powder used for aluminum flowed at a lower temp.

Thanks, all I know is most (unless it's low heat which is costlier) powder melts at about 400 degrees.

I wish I cou;d remember what temp my powdercoater says he uses for aluminum. Seems like it was around 375. I trust him though, because usually when I'm there I see pallets and totes loaded with aluminum parts that he does for Frieghtliner.

You have to press the steering stem out of the bottom clamp to remove the lower bearing.
My powdercoater bakes his parts at 400 f.

before sanding !

electro-powdercoater !

10 minutes steel or
aluminium no problèm !
200 degrees only !!

1982 frame !

an angle grinder works as well. then a bit of gal pipe as a drift to reinstall.

Powder will cure at low temps you just have to bake it longer.

Hubs come up a treat.
