I have one bar of this stuff but it pops a once in a while. Not sure but might be 5 LB's. Looked it up and found this. Nickelite Babbitt Metal, 6-7 lb. Ingot (Specialized Use)
89% TIN, 7.5% ANTIMONY, 3.5% CU, AND ALUMINUM. Brinnell at 215 degree's is 16.6. Also see where it sells for $225 for a 7 LB shiny new bar but scrap dealers wouldn't pay 10% i'd bet. I mixed a bar about 50/50 with lead once and poured 230 grain 45 ACP bullets, no wonder they looked so good.
