In the metal titanium, niobium wire niobium zirconium made alloy ingots. First, roll the niobium zirconium alloy ingots to a suitable size, the pickling surface of the niobium rod to remove oil and impurities, and then clean with water, trim both ends of the niobium alloy rod, and then clean again. Finally, the niobium silk is trimmed and stretched many times according to the actual needs until a suitable size is found.
Niobium and niobium alloy rods and wire materials are widely used in chemical, electronic, aerospace and other fields due to their high melting point, corrosion resistance and good cold processing properties. Niobium density 8.57/ cm 3, niobium and niobium alloy bar are used as structural material of aero engine and rocket nozzle, internal components of reactor and cladding material, making various corrosion-resistant parts under the condition of nitric acid, hydrochloric acid or sulfuric acid corrosion. Adding zirconium into niobium can obviously improve the oxidation resistance and strength of the materials.
Niobium zirconium alloy refers to the alloy composed by adding zirconium to the metal niobium. The main niobium zirconium alloys are nb-1zr alloys. Zirconium added in niobium can improve the strength of the alloy without affecting the plasticity and processing properties of the alloy. Zirconium can also improve the oxidation resistance and corrosion resistance of the alloy. Nb-1zr alloy is the most widely used niobium alloy, is a low-strength niobium alloy, good processing and welding performance, mainly used in aerospace, nuclear reactors, new type of electric light source sodium lamp and other application fields.
