I was down in the city yesterday, and I took along some copper and stainless steel to sell for scrap. While doing so I noticed a box with 5 bars of 40/60 and one marked 63/37 solder inside, I asked the atendent what he would sell it for he told me $1/lb. (the price for scrap lead) As I dug deeper in the box there were 11 1lb bars marked SN 50B, very malable won't break
( not sure what the 50B stands for),
10 lbs of thin strips of mystery metal, shiny, light, malable yet breaks (sn and sb?) the bottom was full of linotype, total weight of the box, 48 lbs. Why not take a chance? 27 lbs of known aloy and possiably 20 more lbs tin or tin aloy So I payed the man and took it home.
With no real way to test the mystery metals I took samples of each and melted watching melting time compaired to known samples (no casting thermonitor) melts @ low temp good sign next I cast several boolits of each from a lee 255gr 452 rf mold and some from lead free solder(the closest thing to pure sn I have for comparison)
lead free solder boolits weigh 172grs
SN50B boolits weigh 180.5grs
mystery strips boolits weigh 189.5grs
pure pb boolits weigh at 261.5
40/60 solder at 213grs
they cast very shiny bullets and fairly hard ( no bhn tester either:roll:) so I do not think I have pure tin in the mystery metals but have a very high content. All in all I don't think I did bad @ $1/lb.
any thoughts?
