Niobium-Zirconium Alloy
Niobium-zirconium alloy is an alloy material with excellent physical properties. It is mainly composed of metallic niobium and metallic zirconium. Through alloying, the strength and corrosion resistance of niobium are improved, while maintaining the good plasticity and processing properties of niobium.
Physical properties of Niobium-zirconium alloy
• High strength: The addition of zirconium significantly increases the strength of the alloy without affecting its plasticity and processing properties.
• Good corrosion resistance: Niobium-zirconium alloy has good corrosion resistance against acids, alkalis and salts, especially in high temperature and high pressure environments.
• High temperature stability: At high temperatures of 300 to 400°C, niobium-zirconium alloy still maintains good mechanical properties and corrosion resistance.
• Oxidation resistance: Niobium-zirconium alloy can grow a protective new oxide film where the oxide film peels off, showing excellent anti-oxidation properties.
• Tensile strength 84MPa, yield strength 78MPa, elongation 15%.

The processing process of Niobium-zirconium alloy
Alloy preparation: The preparation of Niobium-zirconium alloy can be carried out by a variety of methods, including consumable arc furnace, electron beam furnace or a combined smelting process of the two. For products with lower purity requirements, they can also be pressed and sintered into alloy ingots by mixing niobium powder and zirconium powder.
Heat treatment and forging: The smelted alloy ingot needs to be hot extruded or hot forged to open the blank, and then made into various profiles through forging, rolling and other processing processes. Powder sintered ingots can be directly processed into materials.
Plastic processing: The plastic processing of Niobium-zirconium alloy includes forging, extrusion, rolling and drawing to produce products such as bars, plates, strips, foils, pipes, wires and special-shaped materials.
Cutting and welding: Niobium-zirconium alloy is easy to wear and stick to the tool during cutting, so it needs to be cooled by coolant. Vacuum electron beam welding and inert gas shielded welding can be used for welding.
The specific steps are as follows:
Alloy preparation: Press the zirconium sponge into a zirconium electrode, then weld the niobium bar and the zirconium electrode to make a Niobium-zirconium composite electrode rod, and then weld the composite electrode rod into a melting electrode for smelting. This method can ensure that the alloy composition is accurate and evenly distributed.

Plastic processing: Through forging, extrusion, rolling and drawing, various shapes of materials such as bars, plates, pipes, etc. are made. This process requires temperature and pressure control to ensure the performance of the material.
Cutting and welding: During cutting, coolant is used to reduce tool wear and adhesion. Vacuum electron beam welding or inert gas shielded welding is used during welding to ensure welding quality.
Applications of Niobium-zirconium alloy
Aerospace: used to manufacture high-temperature components and corrosion-resistant structural parts.
Nuclear industry: used as nuclear fuel cladding material in heavy water reactors, nuclear power plants and submarine reactors.
Medical field: as an ideal orthopedic implant material, such as knee joints and hip joints, etc.
