Application areas

WVMW and S-WVMW were developed for use as anode materials for short-arc lamps of diameters greater than 15 mm. S-WVMW is particularly suitable for rod diameters greater than 30 mm. Thanks to the special production process that is used to manufacture S-WVMW, it's possible to achieve high densities in the rod core.
