Can anybody tell me if magnetic stainless wire brushes are still OK for cleaning aluminium prior to welding? I am just about to start tig welding aluminium for the first time and have been offered some stainless wire brushes at a good price,however when I tested them with a strong magnet they were weakly attracted to the magnet, So the question is are they worth buying or not.
P.S. been reading lately that most people now just use the red tungstens for everything, is this quite a wide spread practice?
Best regards Gordon,
