Niobium Metal Wire

Product Introduction

Niobium metal wire is a kind of niobium metal material in the form of wire, usually made by drawing niobium billet.Its diameter ranges from very fine gauge for delicate electronic components to coarser gauge for special industrial uses.

The Niobium Metal Wire manufactured by Shaanxi Chuanghui Daye Metal Material Co., Ltd. is a high-performance refractory metal product known for its outstanding corrosion resistance, excellent ductility, and stability at high temperatures. With purity levels up to 99.95%, our Niobium Metal Wire meets ASTM, AMS, and ISO standards, making it suitable for demanding environments such as aerospace, electronics, medical, and chemical industries. Thanks to its high melting point and exceptional formability, it is widely used for manufacturing superconducting materials, heating elements, capacitor leads, and vacuum components.
