Not sure if this is the best place and it's a question for Al really but what the hell...
Stumbled upon a new (to me at least) flavour of filler wire... http://www.ewm-sales.co.uk/online-shop/welding-filler-materials---tig-welding-rods/ewm-tig-welding-rods-aluminium/ewm-tig-welding-rods-tr-1450-995-ti.php. Struggled to find much about 1450 but the sales blurb suggests it's more forgiving than 10xx with similar ductility. The fine grain structure thing... any idea if the difference is enough to notice in the way weld metal would workharden in real life or are we talking differences that the average tin basher is unlikely to notice when planishing/wheeling welds?
