  • Alumaloy

    Has anyone ever used Alumaloy for repairing aluminum or pot metal?
    I saw an infomercial showing how easy it is to melt and repair aluminum.
    It melts like solder, but is suppose to be stronger [39,000 psi tensile strength].

    I saw that Infomercial a while ago and posted the same question on another board. Nobody knew anything.

    Then last week I had a sales rep come into my office and we were talking welders and he mentioned that he had some.
    He said it is actually as good as the ad says, and REAL EASY to use. He told me he has patched boats, blocks, and alum castings. All with a propane torch. The secret is clean, clean, clean.

    I think I am gonna have to get some and try it!

      there 3 towns away from me

      ive seen the comerical before(they air it all the time here ) i am kind of skeptical but for the price you cant go wrong. how much would setting up your mig to weld aluminum cost ? or buyind a tig machine for 2000.00 ???? i have seen people weld aluminum with a stick machine YUCKY and ive seen it done with o/a set up either way you GOTTA be good.

      so for the 40 or 50 bucks it cost plus a propane torch what do youhave to lose ? let me know the results .....brian

        There are several manufacturers of aluminum brazing alloys. The key to remember is that it is no different than soldering---they both rely upon lap joints with absolutely correct fitup, and capillary action that is the strength of the joint. I would check out others before buying the alumaloy, because I think they are charging high prices to pay for their 'gee whiz' marketing campaign. Does it meet any AWS spec like other solders and brazing fillers do? I went to the site and there was absolutely no information. Check these out and if you have questions, give them a call.

        Just remember that you are brazing/soldering and not welding. All joints should have a sufficient overlap if strength is important. Read carefully what the mfgr recommends for joint clearance as well. Ever try to solder copper tube with a big gap? You get the picture.

          That Magic Rod Is Ok By My Standards

          I bought a pound of that stuff from HF Salvage 10 years ago and only had cause to use it a few times as I tend to stay away from aluminum as best I can. I first saw it at an airshow where they were fixing holes and tears in coke cans and it worked nicely. I myself used it to fix a vibration worn tear out in a cowl mount on my Cessna 150. I only had a turbo torch on hand so tried to be careful but slagged the area down anyways. In the end I filled the whole mess with the stuff ground, shaped and redrilled the mount hole. Whatever that stuff is it drilled more like steel and has worn like steel over the years in a shaking vibrating environment. I missed the lineup by a tad so the zeus fastener rubs on one side some and it still hasn' t shown wear. While it may not be up to some professional standards personally I rate it right up there with JB Weld for fixing those impossible tasks. One time I did ask about it at the local welding supply and they spoke of it like it was something outside the realm of real welding.
