Thank you for that...so something like tungsten or tungsten alloy would fall into that bucket...made in wires and apparently being used in some 3D printing with powders...I assume that pyrogenisis has looked at this?...does the market drive the testing, customer request, or proactive/ preemptive research? This is something that would touch on certain of the markets that you may already serve given its unique properties ..defense, medical, high end tools, etc.
