In order to obtain the required surface quality, the production of Zr-4 pipes usually uses a cold rolling process rather than a drawing process.
Due to high consumption and strict standards, nuclear fuel element cladding tubes are usually cold rolled with two or more rollers.
Niobium and zirconium rods are made of niobium powder as raw material and are forged and polished. They are used in steel, metallurgy, atomic energy, superconductors, medical equipment, etc. Stanford Advanced Materials (SAM) has over twenty years of experience supplying high quality niobium alloy rods at competitive prices.
