  • curing aluminum/steel brake drum

    Hey guys, hope somebody can give me some advice.

    I am refurbishing some Pontiac 8 lug wheels. If you are not familiar with them, they are a basically a finned aluminum brake drum with a steel friction surface inside. I would like to powder coat the outside of them, but my fear is the heat from the curing process will loosen the inner steel liner.

    Will the cure temps be a problem, or should I paint them instead?

    Thanks

    i do aluminium cylinders that have steel sleeves in them and aluminium cylinder heads with steel guides and valve seats and also motorcycle Wheel hubs with steel brake liner in them and had no problems so far after couple of years. but i would suggest to stay below the 400 degree

      Thanks for the info!!

      Is there a "rule of thumb" temp that you use for those kind of parts, or just stay below 400 degrees?
