I have about 45-50 pounds of mystery alloy. I filled my pot with it, leaving bout a pound of ww +1%sn when I switched. Well it gets a golden oxide on the surface and on the dipper, a lot of it. So, i figure it's a high tin alloy. I get mild frosting. It casts wonderfully.
I'm thinking the frosting is from the little bit of alloy left in my pot when I switched. I'm also thinking it's a fairly high tin alloy.
How much tin does it take to get that golden oxide? My ww+1-2%sn doesn't turn golden. I can dimple and scratch a resultant bullet easier than my WW alloy.
I'll probably empty my pot completely and melt some more to see if it frosts too.
I'm wondering if it might be worth having a sample tested, cut it 50/50 with ww alloy to stretch out my supply, or if I aught to just use it for pistol bullets and be happy.
Preciate the input.
