LAT International made something akin to an alloy, they are no longer around unfortunately.

Here's an explanation of their process.
EXPLANATION OF OUR PROPRIETARY SILVERFUSE/NANO PARTICLES CONDUCTOR MATERIAL: Silverfuse/Nano is a near alloy of silver and copper. The copper used in this process is Single Crystal Continuous Cast Copper. It has unique physical and chemical properties, such as considerably longer granules with absolute absence of gaseous impurities such as oxygen, carbon, hydrogen and nitrogen. It is free from impurities (up to 99.99998% pure copper). It is far better than continuous cast Oxygen Free High Conductivity wire (OFHC). IT IS NOT SILVER PLATED. Silver plating causes a dioding effect when signal is passed through resulting in brightness and distortion. Because silver plating has a bad reputation, some manufacturers try to disguise the fact by calling it silver coated, silver clad or silver/copper hybrid. But they are all silver plated. Our Silverfuse process starts with Single Crystal Continuous Cast Copper wire with a diameter that is slightly larger than the required size. It is then pulled through a trough of molten silver and Nano particles. The wire with this deposit on it is then forced through a compacting process where it is subject to tremendous pressure. The silver with Nano particles and the copper are fused together into a near alloy. The compacting fusion also reduces the wire diameter to the desired size.
Final step; Deep Emersion Cryogenic Processing.
No dioding subsequently occurs with this process. The result provides for the benefits of silver; which are excellent definition and clarity, with the high purity copper benefits of warmth and mellowness. (Incidentally, pure silver wire also causes brightness)
