Product Details

High-purity niobium rods can be used as materials for aircraft engines and rocket nozzles, coating materials for reactors and internal components, niobium rods have corrosion resistance and high-temperature resistance, so they are widely used in superconducting applications, superalloys, and other fields. Niobium is used in surgery. It also plays an important role in surgery. It can not only be used to manufacture medical devices, but also is a good applicable material because it has excellent corrosion resistance, does not interact with various liquid substances in the human body, almost does not to damage the organism's tissue at all, and can adapt to any sterilization method, so it can be combined with the organic tissue for a long time and stay harmless to the human body!

The niobium rods produced by Yusheng Metal are made of high-purity niobium powder, which is a refractory metal. Refractory metals are metals with a higher melting point (1772°C) than platinum. In refractory metals, the energies that bind individual atoms together are particularly high. Refractory metals have high melting points, low vapor pressures, high elastic modulus, and high thermal stability. Refractory metals are also characterized by low coefficients of thermal expansion. Compared with other refractory metals, niobium has a relatively low density of only 8.6g/cm³.

High-purity niobium rods and niobium alloy tubes, rods, and wires are widely used in the fields of chemistry, electronics, aviation, and aerospace due to their high melting point, corrosion resistance, and good cold working properties. Niobium and niobium alloy rods are used as structural materials for aero-engines and rocket nozzles, reactor internal components, and cladding materials,  Niobium rods are used in aerospace, medical, and other fields.

A forging method for a high-purity niobium bar comprises the following steps: the outer circumference of the niobium ingot is polished, the turning dimension is based on the surface quality, and the step is allowed to have a step, and the step needs to be inclined to transition; the niobium ingot is forged on a radial forging machine, press down 20 ~ 30mm, pull down speed ≤1.5 m/min, single pass pull down, no reciprocating forging, water pipe spray cooling, dynamic real-time temperature measurement, process temperature， and final temperature & LT; 330 °C, otherwise stop forging, the billet was lifted from the forging machine and cooled in water for 15 ~ 20 min, then moved up and down, and the depth of the water was more than 0.5 m. The Billet was forged on the radial forging machine after being cooled in water, the reduction was 5 ~ 10 mm and the drawing speed was less than 1.2 m/min,  single Pass pulling and hitting, no reciprocating forging. Turn on the water pipe to spray and lower the temperature. After forging, take advantage of the residual temperature to straighten the straightening machine. After finishing the straightening, spread the air-cooled air-drying material horizontally. Stacking is prohibited, the surface of the forging method has no blue skin phenomenon, which improves the surface quality, improves the finished product rate， and reduces the manufacturing cost.
