Tantalum Niobium Surface Alloy Products

Tantalum-niobium surface alloy products, with extremely high corrosion resistance, provide you with the latest protection solutions to help you overcome industrial corrosion problems.
The tantalum-niobium surface alloy eliminates the high cost troubles of traditional tantalum-niobium alloys, and allows you to obtain better product performance, safer working environment and higher economic benefits at lower costs.
The surface of tantalum-niobium alloy is uniform, stable and corrosion-resistant, and the combination with the base material is firm. With the corrosion resistance of tantalum-niobium metal and the hardness of standard materials, our products can withstand highly corrosive, high-temperature and high-pressure working environments, making them an excellent choice for process equipment that requires extreme corrosion resistance.

In a typical sulfuric acid and hydrochloric acid system, tantalum metal requires more severe corrosion conditions than metals such as zirconium, niobium, and Hastelloy. It can be concluded that in acid environment, tantalum has significantly better properties than other metals. of corrosion resistance.
