babbet

[wgr]

can any one tell me the make up of Babbitt

[Graybeard]

No not really. 

The reason is that babbit is not a single material with a fixed composition but rather is many different materials with many different compositions. Some babbits have totally different metals making them up than do others. So it's really impossible to know what you have unless it is in some way marked as to "which babbit" it is or unless you have it analyzed.

Yes, it can be made of many different alloys, but if you happen to have tin based babbitt, it is very useful as a source of tin. You need to watch out for babbitt that has a lot of copper in the alloy. It can still be used in bullet alloy, but requires some extra steps.

dont know about the babbit with higher consentrations  but what i have is 3.5 percent copper and I used to try to remove it and found it didnt hurt a thing. Some casters will even tell you to leave it as it increases shear strenght of your bullets. I guess you have to understand that your  bullets arent 3.5 percent copper. You are usually only adding 3-5 percent babbit to your mix so the ammount of copper in your final alloy is so minute that it effects nothing.

I've been using grade 4 nickle Babbitt for 7 or 8 years now. It's lead free, as per OSHA's requirement, and is mostly tin. By itself it makes a rather light bullet that is very hard, and mixed with lead or WW it still makes a good hard alloy. What's really nice is that I can get an ingot every now and then for free!
