Zirconium Titanium Molybdenum Tungsten Alloy Rods High Strength Low Resistivity

Tungsten has the characteristics of high melting point, high strength and hardness, good performance at high temperature, low resistivity, small expansion coefficient, and small electronic work function; therefore it is the metal material which is most widely used in high-temperature conditions.

Molybdenum has good thermal conductivity, electrical conductivity and low expansion coefficient (which is similar to glass for electronic tubes), and high strength at high temperature (1100~1650℃); compared to tungsten, it’s easy to be processed, thus be widely applied in manufacturing of electronic tubes (grid and anode), and electric light source (support materials), and metal processing tools (die-cast and extrusion mold and perforation heads), and applied in the aerospace industry.

Tungsten copper composite assembly for partial filter of nuclear fusion device:International Thermonuclear Experimental Reactor(ITER) is a superconducting tokamak that enables large-scale nuclear fusion reactions. The plasma torus is in the ring-shape sheath of the shield blanket. The shield blanket will absorb 500,000 kilowatts of thermal power and all neutrons generated by the nuclear fusion reaction.

Plasma-facing material is one of the most critical materials in the fusion reactor. The main requirements of the material are with low sputtering rate, high thermal shock resistance, high heat load capacity, low tritium retention, low activity radioactive and low decay heat.Tungstencopper composite parts, TZM materials produced by AT&M can be used as the first-wall materials.
