99.95% Various Sizes Niobium Filament Niobium Wire
1. Specifications
Niobium wires
Material:RO4200-1, RO4210-2A
Size: Dia0.25~3mm
Standard: As per ASTM B392-98
Purity: Nb>=99.9% or 99.95%
2. Description
Niobium wire is a preferred choice for jewelry making due to its hardness and corrosion resistance. By adding zirconium in niobium wire, the hardness and antioxidant properties can be greatly improved. Its diameter can be ranged from 0.4 mm to 1.5 mm or from 3.0 mm to 6.0 mm. Niobium wire can be offered by hot rolled, cold drawn or annealed process.
