prototype castings needed right away

Date: Thu Aug 09 2001 - 21:12:51 EEST

Here's my story - I had a job being prototyped - 10 pieces of an aluminum 380
diecast heatsink being prototyped in 356-T51 aluminum as investment castings.
Unfortunately, my customer needs these parts for physical testing & the
thermal conductivity of 356 is too high. The foundry we had lined up only
pours 356.

As of tomorrow I will have 12 SLS Castform patterns ready to ship. I need
someone who can convert these patterns into castings in one of the following
3 alloys:

A380 - diecast alloy
A380-T5 casting alloy
707.0-T7 casting alloy

These are the only 3 alloys I could find that have Thermal Conductivity < or
= to A380 & similar UTS & YS. If you know of any other alloys that would
work, I'm open to suggestions but it cannot exceed the Thermal Conductivity
of A380 at all.

Any takers?
