when making a lead tin alloy like 20/1 or 16/1 what effect will a small percentage of antimony have on the alloy (say 1%) [smilie=s:

1% antimony will raise the BHN up 1 or 2 points.

I would think that the high tin ratio would cancell out some of the little dab of antimonies' effects.
Anyway I bet it won't make enough difference to concern about.

IT only makes the alloy better, unless you are casting LHP. Then I would rather have none or a very small % of antimony.
