want to know more about Zamak 3

want to know more about Zamak 3

want to know more about Zamak 3

(OP)
hi, new here, now my background in metals was mostly in the aluminum and steel sector...heat treating, and manufacturing...but i do not really know much about zamak...

recently i picked up a project that is a bit unusual...

to finish it, i may have to build up the surface of a zamak part...it is not a repair, and casting a replacement is out of the question...

what would happen if i pour molten zamak into or on to a clean zamak surface? would it bond with the zamak that is cold? could it be brazed on like alumiweld? im talking about a work piece and molten zamak of the same identical composition being used to backfill or build up a surface...

any zamak gurus available?

RE: want to know more about Zamak 3

You will duplicate a casting defect known as a "cold shut", which is when two streams of molten metal converge but do not fuse.
I would look at TIG welding for your project. Zinc rods are available as "lumiweld",intended for soldering aluminum.

RE: want to know more about Zamak 3

If this is meant for a structural application, then I completely agree with swall. If it is just a static application for cosmetic or other reasons, maybe you could do something along the lines of your proposal.
