might have mis-labeled lead

[bmortell]

you know how after casting you gotta wait till the lead is cold to mark what alloy it is then pop it out of the bowl next time you wanna do a different alloy. well I believe I marked wrong cause I ended up with 2 marked the same and none marked wheel weight anymore. the alloy is 2.3 tin and 3.6 antimony from certified metals the two are marked. one of them may be WW, is there a way I can tell without a hardness tester? I was thinking I could make a water quenched bullet out of each presuming the ww would get harder and do a water expansion test. or should I just reserve each to air cooled would they be the same hardness then and not matter or would the WW one still get harder ?

mainly its just OCD freaking out cause I messed something up and don't know whats what

[Peregrine]

How much of both do you have? The lazy solution would be just to mix the two of them together if you have similar amounts, that should get your pretty close to WW+1% Sn and we all know that's a winner as far as alloys go.

Look up pencil lead hardness testing.

Two different ingots, one ball bearing, one vise, squeeze ball between ingots. Rich alloy (2.3/3.6/94) should have smaller dent.

ah nice, that's a good idea.

I like the idea of mixing them together and calling it a day. I doubt with those concentrations of tin and antimony you'll be far off the hardness of W-W alloy anyway.
