How does antimony improve lead-based castings?
In lead-based alloys, antimony is added in the range of 1/2 percent to 12 percent and most commonly it is used in a range of 1/2 percent to 6 percent antimony and the balance of the alloy is lead or tin. The use of a little antimony in castings will help material flow so it acts to improve the feed into a part compared to pure lead.
