In addition to pure molybdenum, tungsten, niobium and tantalum, we also supply wires made of a variety of alloys:
Molybdenum-lanthanum (ML) provides excellent performance due to its high ductility, creep resistance and recrystallization temperature.
Tungsten-rhenium (WRe) shows high ductility.
Molybdenum-tungsten (MoW) provides particularly high corrosion resistance against zinc.
Grain-stabilized tungsten (WVM) offers especially high dimensional stability and possesses excellent corrosion resistance against many molten metals.
Wires as fine as 0.015 mm.
We supply fine wires made of molybdenum and tungsten. These can be as fine as 0.015 millimeters.
Fine tungsten wire is used, for example, in halogen lamps, incandescent lamps and fluorescent lamps. When used in halogen lamps in vehicle headlamps, our wire excels due to its freedom from fissures, outstanding surface quality, very low diametric tolerance and stable mechanical properties.
Almost invisible, our fine tungsten wires heat the windshields of modern vehicles. In this application, the low tolerance ranges required for electrical resistance and the high surface quality of our wires are particularly important.
Among its other applications, fine molybdenum wire is used as support wire in incandescent lamps and core wire in the manufacture of lamp filaments

A favorite with chemical processing applications that require anti-corrosion characteristics is tantalum rod including the manufacturer of components for anticorrosion equipment.
Outstanding refractory, anti-corrosion and biocompatibility properties make our tantalum wire a unique material for selected applications. Customers transform our tantalum wire into leads for Ta capacitors in electronic, anti-corrosion chemical processing, biomedical devices for medical applications, and filaments for lighting applications. Shenzhen Sunrise Metal Industry Co.,Ltd’s tantalum rod is worked cold from ingot to final diameter. Forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size.
Proprietary techniques have been developed by Shenzhen Sunrise Metal Industry Co.,Ltdto overcome the metal's extremely high-galling tendencies. Special lubricants and die design, as well as suitable speeds and reductions per pass, are all a part of cold drawing tantalum.
Our tantalum rod is generally supplied with a forged surface above 1-3/8" diameter and a swaged or drawn finish in smaller diameters. The rod, preferably unannealed, may be centerless ground to improve diameter tolerances. The minimum diameter for centerless grinding is .125". Shenzhen Sunrise Metal Industry Co.,Ltd’s tantalum rod is produced to a maximum of 1/4" and wire may be supplied in coils or straightened and cut to length.
Tantalum wire with a diameter of 0.040“or below is shipped on spools.
ULTRA76 tantalum alloys offer higher corrosion resistance in most environments creating additional value through extending the products service life, reducing material thickness and improving processes throughput.
Higher temperatures possible, shorter cooling/heating cycle times

Specification: 0.3mm ~2.5mm/3mm-10mm Execution standard: ASTM B365-98 Tantalum dosage the biggest, in the electronic industry is mainly used for tantalum electrolytic capacitor anode lead. High oxygen embrittlement tantalum capacitor can also be used for making tantalum foil, it can be in the assignment of potassium dichromate and sulfuric acid to liquid, in the high temperature (100 ° C) and 772 under the condition of high voltage (350 v) flash fire work. In addition, the tantalum also can be used as a vacuum electron emitting cathode source, ion sputtering and coating materials, etc.
