Typical application : Niobium -1% zirconium (Nb-1Zr) alloy tube can be cut into the small tubular parts, it is the mainstream choice for the critical metal parts in HID (High-Intensity Discharge) lamps which goes beyond the traditional incandescent and fluorescent lighting, widely used in outdoor lighting systems as the mercury or sodium vapor lamps, providing more lumens per watt than conventional outdoor lighting systems, saving both money and energy.
