Tungsten, which has the highest melting point among all metals, is used for electrode material for discharge lamps
Conventional tungsten is inadequate for recent discharge lamps that require higher output and larger size.
SMD-W (tungsten) is high-density tungsten manufactured, using our know-how can provide superior characteristics for discharge lamps that cannot be obtained with ordinary tungsten.
Beyond a rod material, we can also offer after applying final shaping and finishing of the electrode according to your requests.
