Application for Nb tube
Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties, it resembles tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents.
Nb capillary tube and Nb-Zr capillary tubes are often used in high-pressure sodium lamp production.
Machined & customized Niobium parts are also available. Contact us at sales@edgetechmat.com for any inquiries and questions on niobium and its alloys products.
