Mornin' JK & All

Take a look at <http://www.lfa-wire.com> Little Falls Alloys - Paterson NJ.
They may be able to assist, or provide guidance.  I had a number of projects
which were worked with them years back and found them to be a great bunch of
folks to work with.

Regards  - Kelly

Subject: [TN] small qty wire drawing facility


>TechNetters:
>Does anyone know solder wire drawing facility who would do small quantity
>work?  I have 8 lb of high creep resistance soldering wire need to be
>re-drawed to smaller diameter.  The alloy is after market product (can't
get
>it anymore in north America).  The material is Sn/Ag/Sb/Cd(1%).  The
current
>material is in spool format with diameter of 35 mil.  I would like to
reduce
>the solder wire to 20 mil.  (I did some experiment using Instron with
>heating zone, with papameter of 2 lb constant force, withdraw rate of 50
>mil/min. and approx. 70-80 C produce relatively consistant 20 mil wire = 1
>ft long....Don't laugh at me if you have the dies and drawing

>precious metal solder guy would not touch it (it will contaminate their
