Hey guys, I'm new to the forum. I've been looking for decently priced aluminium rectangular bar stock. I've ordered from metal supermarkets and online metals in the past, and while their metal is fine of course, it is pricey. The shipping and handling hits me pretty hard as well since I'm in cold lake. John- I'm going to check out Samuels for sure if they have a volume discount. I have found an unlikely supplier that may end up alot cheaper than the "small quantity consumer" companies though. I gave Sculpture Supply Canada a call today, and it seems that they have what looks like 3"x3.75" aluminium bar stock 30" long (the alloy is A356). They're selling it as an "ingot" by the pound. Approximate weight is 35 Lbs and they quoted me $2.25/lb over the phone. With UPS standard shipping being $100.00 for that weight and dimension, total cost should come out to about $180.00 before taxes. An approximately equivalent sized bar of 6061 of the same weight from metal supermarkets costs about $315.oo with shipping and before taxes. I'm not sure how good A356 alloy is. Comparing the material properties data sheets it looks like has lower tensile strength than 6061, but I'm not sure how much that matters for most applications.
