Vanadium aluminum alloy is a vanadium additive for the production of titanium alloys such as Ti-6Al-4V. According to the vanadium content, it is divided into 50%, 65% and 85% 3 levels, and the balance is aluminum. Because it is an additive for vacuum smelting, it is often labeled "VQ" (Vacuum Quality). The vanadium-aluminum alloy has a low gas content, and other impurities such as Fe, Si, C, and B must meet the requirements of titanium alloys. The production of vanadium pentoxide for the production of titanium and aluminum alloys is to purify industrial products, so that the impurity content reaches the specified range of high-purity vanadium pentoxide. High-purity aluminum is used for aluminum. The production site should be kept clean to avoid contamination by impurities.

Physical state

Appearance is silver-gray metallic luster. With the increase of vanadium content in the alloy, the metal gloss increases, the hardness increases, and the oxygen content increases. When the vanadium content is> 85%, the product is not easy to be broken, and the surface is prone to produce an oxide film. The particle size range of VAl55-VAl65 grades is 0.25-50.0mm; the particle size range of VAl75-VAl85 grades is 1.0-100.0mm.

use

Vanadium aluminum alloy is an intermediate alloy, which is mainly used as an element additive for the production of titanium alloy, high temperature alloy intermediate alloy and some special alloys.

Vanadium aluminum alloy is an advanced alloy material widely used in the aerospace field. It has high hardness, elasticity, seawater resistance, and lightness, and is used to make seaplanes and gliders. Only a few countries in the world, such as the United States and Germany, have realized industrial production. In the process of developing vanadium-aluminum alloys, the technical staff of Panzhihua Iron and Steel broke through foreign production processes and analysis and testing. Through a large number of experimental studies, a complete, good precision, wide detection range, simple and fast, and practical operation of vanadium aluminum The chemical composition analysis and test method of the alloy can accurately determine the main elements vanadium, aluminum, and more than 10 trace impurity elements such as carbon, sulfur, silicon, and manganese in vanadium-aluminum alloy, which satisfies process research, production, and products. Need for quality control. Using this research result, Pansteel Steel Research Institute and Panhong Company have successfully smelted products with chemical components that meet German and American technical standards and lower costs, and are moving towards industrialization.
