Vacuum arc furnace “VDP-12,5R”

Appointment
Vacuum arc furnace “VDP-12,5 R” is made for production of high strength and high electricity-conductive Cu-Nb wires of round and rectangular wire sections in a wide range of sizes with adjustable combination of strength and conductive properties.
“VDP-12,5 R” provides obtaining of ingots of composite alloys Cu-Nb, Cu-V type and other by method of alloying of consumable electrode by electric arc in the bottom mold.
