Products Description
The production process of tantalum rods is relatively complex and mainly includes smelting, processing and heat treatment. In the smelting process, tantalum in tantalum-niobium ore needs to be decomposed, purified and separated to prepare pure tantalum or tantalum alloy. Then, the pure tantalum or tantalum alloy is made into rod-shaped materials that meet the requirements through processing, molding, heat treatment and other steps. Among them, the heat treatment step is very important to improve the relative density and properties of tantalum rods.
The melting point of tantalum rods is very high, reaching about 3000 degrees Celsius, which is one of the highest among common metals. This makes the tantalum rod have good stability and corrosion resistance in high-temperature environments. The thermal expansion coefficient of the tantalum rod is very small, which means that its size changes little when the temperature changes, which is conducive to maintaining the accuracy and stability of the equipment.
Tantalum rods are available in various specifications and purities. Generally speaking, the purity of tantalum rod can reach 99.95% or 99.99%, and the material is usually tantalum-tungsten alloy rod. Its brands are Ta1, Ta2, R05200, R05400, etc. The implementation standards include ASTM B365 and GB/T26012-2010. In addition, the dimensional tolerance and mechanical properties of tantalum rods are also strictly regulated to ensure that they can meet various application requirements. Tantalum rods can be used to make digesters, heaters, coolers and other equipment, as well as various utensils and devices. Its excellent corrosion resistance enables tantalum rods to run stably in these devices for a long time.
To sum up, tantalum rod is a kind of metal material with many excellent properties, which is widely used in many fields such as the chemical industry, electronics, medical care and aerospace. With the continuous development of science and technology, the application field of tantalum rods will continue to expand and deepen.
