Can anyone tell me how Tungsten Copper is made into heatsinks including how the alloy is made itself?

I've looked everywhere and cant find anything. Tungsten copper is definaly used for heat sinks, thier all for sale all over the internet, i know, thats all i found on tungsten copper. also, i've been asked to research how thier made so they are :P

1. Making the alloy... If you look at the properties of Cu and W, you will notice that the melting point of W is in the same temperature neighborhood as the boiling point of Cu. This suggests that it is difficult to make a alloy of Cu & W thru conventional melting and casting (difficult but not impossible). It also depends on composition, mostly Cu with a little W is one thing, mostly W with a little Cu is quite another. The most common method is powder metallurgy, get Cu powder and W powder, weigh out how much you want of each, blend them together, press the loose powder in a die (green compact), then sintering it to get the powder particles to stick together better. Depending on composition, the sintered body may be able to be worked via conventional forging/rolling/etc. This You may want to consider if you really need Cu-W or some other material will work.
2. Tungsten copper is not suitable for heatsinks, since it has high density and low thermal conductivity - exactly the opposite of what you need! Are you sure you don't mean beryllium copper? That is very good for heatsinks, but also very hazardous. It is often used on spacecraft.
