Scratch Posted November 7, 2008 Share Posted November 7, 2008 The color and weight should obviously be a good clue, but if for some reason you can't tell the difference... bring a magnet. Be careful though... some stainless is not magnetic. Quote Link to comment Share on other sites More sharing options...
Max Mulholland - Tetnum Posted November 7, 2008 Share Posted November 7, 2008 are you going to melt it , use it in the structure ,or something else MAKE SHURE YOU KNOW IT IS ALUMINUM MAGNISUEM FIRES ARE BAD REALY REALLY BAD my other concern is zinc and other metals of the same type are all non magnetic and are graysilver in appearence so be careful if in doubt at least ask or just leave it Quote Link to comment Share on other sites More sharing options...

rustyshackleford Posted November 7, 2008 Share Posted November 7, 2008 Since you're going to a centre, you may want to ask. They should (ha!) have things organised by element Quote Link to comment Share on other sites More sharing options...
welder19 Posted November 7, 2008 Share Posted November 7, 2008 If your looking to cast alum. then try to get alum castings and not extruded, get stuff like water pumps and other automotive parts that are cast al. You can look for stuff that has white powder from corrosion, stuff that is grey and not rusty. welder19 Quote Link to comment Share on other sites More sharing options...
Doug C Posted November 7, 2008 Share Posted November 7, 2008 I was given some aluminum stock and horse shoe blanks by a local farrier who had retired. How do I know if this is ok to forge? Quote Link to comment Share on other sites More sharing options...
hill.josh Posted November 7, 2008 Share Posted November 7, 2008 Doug, all aluminum is fine for forging so far as i know. Somebody correct me if thats wrong. I melt aluminum stock then forge it normally so its a larger piece. Quote Link to comment Share on other sites More sharing options...
