# Is there a material that reduces copper melting point and completely dissolves?

Is there any material that you mix/alloy with copper that

• will result in something that behaves similar to plastic (that is at room temperature it is solid, at maybe 500K or similar it can be easily formed/3D printed)
• When heated even more (700K?) it will make the the included copper melt, and dissolves itself, leaving only solid copper.

Is this even theoretically possible? The main goal is to significantly reduce the temperatures involved, 700K is a ballpark number here. Also it doesn't need to be very thick if this makes things easier.

• When heated even more (700K?) it will make the the included copper melt, and dissolves itself, leaving only solid copper. You may be able to make an alloy with a melting point below 500K, but you cannot remove the other metals simply by applying heat. Carbon compounds are burn away above 700K, which is why the plastic binders work. – LDC3 Dec 27 '14 at 18:20
• @LDC3: The problem with those though seems to be that what is left isn't solid copper, is it? – PlasmaHH Dec 27 '14 at 18:45
• That's what I implied, alloys are not going to give you the result that you specified. The plastic binder does, since the carbon compounds are burned away. – LDC3 Dec 27 '14 at 19:14
