32659Re: Aluminum Supply
- Nov 1, 2004Hi Kiwiavi, my experience has shown that the swarf from shops isn't
the best source of melting stock, mainly due to oils and/or solvents
used on the metal when it's machined. They'll create lots of noxious
(not necessisarily toxic, but not conducive to a contructive
relationship with the neighbors) smoke and fumes. I love the smell
of Tapmagic, but not when it's burning... Plus, as others have
mentioned, the small slivers/chips have a relatively large surface
area that will oxidize very rapidly and produce more dross than other
solid blocks the same size. In this situation, it may be better to
pack these into bundles/blocks and take them to the recycler yard for
cash and/or trade for previously cast material. You would actually
have a better casting material with the previously cast metal than
with the swarf too...
