It seems there's been a bit of research into Aluminum Tungsten systems[1]. The alloy systems described in the abstract are strengthened by particle formation (also called precipitation hardening), which is the primary strengthening mechanism used in most Al alloys[2]. In general, alloy design is an extremely high dimensional problem. You have composition, the forming processes, and heat treatments which all can profoundly affect the properties of the finished product. It's only since the fifties or so that we've really started to understand the internal structures of metals and how they affect properties like strength, and there are many open questions yet.
