  • silicon bronze

    Haven't learned much about silicon bronze filler but did finally pick up some at the LWS.

    I've read you can use it with AC or DC. Assuming that's being used on aluminum and steel.

    Also that it tends to shrink less, good for auto body.

    The strength is a good bit less than regular carbon steel filler. Is that true?

    What applications other than auto panels and art do you use it for?

    I bought 50#'s of it from ebay about 3 years ago cheap. 10 bucks a 25# spool and it was on my home from work so no shipping. I use it for sheetmetal. I love it. Just use Argon gas. It likes to be welded with maybe a little gap in the metal because it doesn't melt the base metal it just bonds the two together. I tried it on some galv SM a few weeks ago and i could get it water tight i liked my steel wire better. Here is a little link how they have done it in England for many more years than here. http://www.mig-welding.co.uk/brazing.htm Their forum is good also but lots of the measurements are in MM so they loose me quick...Bob

      I tried it on cast iron with no luck at least with .025 wire. Alum bronze is what you want for that. And i run it just like soild steel wire except with the argon gas...Bob
