Electrode materials for discharge and other lamps
SMD-W (Electrode materials for discharge lamps)
We have developed SMD-tungsten that is most suitable for electrodes of discharge lamps that receive arc and are exposed to ultrahigh temperatures. It has the world’s highest level of density. Though in recent higher power and upsizing situations, it maintains a long life and excellent thermal conductivity.
|For all discharge lamps|
|Improved flushing-resistant performance with grains controlled|
|Further advanced EP specially intended for electrodes|
|SMD-4N||Low impure content
|Used for the types sensitive to impurities (W purity: 99.99% min.)|
|SMD-5N||Ultralow impure content
|Suitable for highest purity requirement (W purity: 99.999% min.)|
Electrodes for ultra high pressure mercury and metal halide lamps
Tungsten electrode assembled with pin and coil. One piece type made by melting.
|CY||Standard pure tungsten|
|EX||Doped tungsten having controlled crystal grains and resistance to deformation.|
|4N-W||Purity of tungsten 99.99% min.|
|5N-W||Purity of tungsten 99.999% min.|
