Sintered, forged and rolled molybdenum bar in pure Mo, TZM and Mo-La alloy. High melting point, good thermal conductivity and low thermal expansion — for electric-vacuum devices, light-source parts, high-temperature heating elements, structural parts and rare-earth electrode bars. Diameters from Ø3.18 to 152 mm, black or polished.
