My employer is switching vendors so I got to take home some left overs from our last vendor. I got 14 tin anode balls. Two inches in diameter. One pound each. Here's the alloy specs: http://www.carteralloys.com/tin.html Chemical Analysis Tin Sn 99.952% Antimony Sb 0.0121% Copper Cu 0.0017% Lead Pb 0.0195% Iron Fe 0.0023% Bismuth Bi 0.0016% Arsenic As 0.0017% Zinc Zn 0.0005% Aluminum Al 0.0008% Cadmium Cd 0.0001% Sulphur S 0.0001% Nickel Ni <5 ppm Cobalt Co <5 ppm Silver Ag <5 ppm At WW + 2% Tin, I'll need 700lbs of lead to make a nice alloy. Next stop: scrap yard!
