hybrid 1043 Report post Posted December 14, 2004 (edited) You may want to get professional advice on this .. as I dont think with that polished rim you can just acid dip them ... it will need to be chemically removed (not bead or sand blasted) but I think you be look at a repaint after the dip. as I said .. talk to a specialist metal shop .. there is one on kyberpass road next to the harley bike place and opposite Jaycar .. im pretty sure its called eden electro-platers. hope that helps [edit] just had a second look at the picture ... the red part .. is it 3 piece ? IE can you get it removed ? Edited December 14, 2004 by hybrid Quote Share this post Link to post Share on other sites
cage 0 Report post Posted December 14, 2004 (edited) i think but dont quote me they are 2 pice so i think you can take the red part out I thik red mags on a red car whould look stupid..... Edited December 14, 2004 by cage Quote Share this post Link to post Share on other sites
hybrid 1043 Report post Posted December 14, 2004 hmm .. you'll be sweet then ... talk to a wheel shop about removing the inner piece .. because (and again dont qoute me) once they go back in .. you may need to put them in as the came out to not cause un-balancing. Then you can just get them dipped and repainted (or whatever) I dipped a new pair of ROH steel rims (for my 4x4) however then were steel and single piece. but yeah the acid dip should be what you need ... do shop around though. Lots of places in south AK... Quote Share this post Link to post Share on other sites

bravo 35 Report post Posted December 14, 2004 Yeah man, I reackon they would prob look cool on your wheels. I don't know anything about removing the coating - my concern would be the standard of finish possible to be obtained after it has been removed. Whatever is under there may not came up too good without some sort of additional treatment?? Found this though on a site related to powder coating in relation to motorbikes: Q. A metallurgist friend told me a few years ago that things like aluminum wheel spindles should not be powder coated. He explained that aluminum billet material (6061-T6 ?) changed crystal structure at a critical temperature around 410 degrees F (as I recall). The thrust was that the heating step would adversely affect the strength of the material. Non-structural components would be OK, but not something that "holds the spokes on". A. The metallurgist is correct. Products like wheel billets, scuba tanks, etc. can be powder coated, but only with powders which cure below peak metal temperature of 300 degrees F. The magic temperature is about 275F. The crystalline realignment at 400 degrees F causes the previous ductile aluminum to become brittle. Imagine the catastrophe when an 80 cu. ft. scuba tank explodes under 3000 psi pressure after an unauthorized powder coat (this actually happened). To my knowledge, all Aluminum wheels and other strength-critical aluminum components are powder coated with these cooler curing powders. Heating Al alloys above this temperature causes a granular rearrangement of the metallurgical structure resulting in a significant change of bulk properties. The tensile strength of the metal is dramatically lowered, much like a stress relief anneal on a steel piece would do. The resultant metal is not as strong, nor will pressure vessels made of such treated aluminum (e.g., scuba tanks) hold near the pressure that they were originally rated for. Since wheels are essentially load-bearing structures, they should never be heated like this unless the alloy is known to tolerate it well. Q. "What is the best way to remove the powder coat without damaging the metal underneath? Are there different removal methods for steel or aluminum?" A. The company I work for (as well as many others) make hot alkaline strippers for paint / powder that are used routinely for powder removal. We even have a hot stripper that takes paint and powder off of aluminum surfaces. Mechanical and burn methods are also regularly used to remove powder.
