Metal finishing Q&As since 1989

How can I safely powder small quantities of zinc lead tin alloy.

March 9, 2013

Q. I want to powder about 400 gram quantities of a zinc lead tin alloy rod and mixing the resultant powder with petrolatum ammonium chloride zinc chloride based flux. The powder should be fine enough to apply with a brush. I will do multiple small batches as needed. I'm aware of the danger of lead dust and this will be done in a shop setting (not a home). What is a low cost/safe method that I may be able to powder this alloy?
I was considering using a heavy duty blender and doing it wet followed by a steel ball mill. Followed by drying of the powder in a beaker over low heat.
