Tantalum is a metallic element with an atomic number of 73, chemical symbol Ta, and its corresponding element form is a steel-gray metal. It has very high corrosion resistance and does not react with hydrochloric acid, concentrated nitric acid, or aqua regia under either cold or hot conditions.
Tantalum primarily occurs in tantalite, often in conjunction with niobium. Tantalum is moderately hard, ductile, capable of being drawn into fine wires and foils, and has a low thermal expansion coefficient. Tantalum possesses exceptional chemical properties and extremely high corrosion resistance. It can be used to manufacture evaporation vessels, electrodes for electron tubes, rectifiers, and electrolytic capacitors.
In medicine, it is used to make sheets or wires to repair damaged tissues. Despite its strong corrosion resistance, tantalum's resistance is due to the stable tantalum pentoxide (Ta2O5) protective film formed on its surface.
Tantalum tubes are special products made from tantalum. They are widely used in the chemical industry, high-temperature technology fields, and atomic energy industries. They are mainly used to manufacture reaction vessels and heat exchangers for chemical processes, pipes, condensers, bayonet heaters, spiral coils, U-shaped tubes, thermocouples and their protective tubes, liquid metal containers, and pipes, among others.
Many critical components in the aerospace and military industries operate under high-temperature conditions, subjected to the combined effects of thermal, mechanical, and chemical processes, leading to severe ablation and wear. Therefore, materials with excellent wear and ablation resistance at high temperatures are an urgent need in cutting-edge industrial fields. Tantalum tube for aviation is one such material with excellent ablation and wear resistance.
High Melting Point: The melting point of the metal element tantalum, used as the raw material for tantalum tube for aviation, is about 2996℃, second only to carbon, europium, rhenium, and osmium.
Strong Conductivity and Malleability: Tantalum’s elastic modulus is similar to steel, with good conductivity and malleability, so tantalum tube for aviation also possesses these characteristics.
Corrosion Resistance: Tantalum has low metallic activity and extremely high corrosion resistance, being able to resist corrosion from various strong acids at room temperature (except hydrofluoric acid and fuming sulfuric acid).
Moreover, tantalum tube for aviation also has good wear resistance.
In summary, the excellent high-temperature mechanical properties of tantalum tube for aviation can meet the requirements of wear and ablation conditions. Rational development and utilization of tantalum coatings can extend the life of workpieces under wear and ablation conditions, save resources, and also achieve good economic benefits and safety assurances.
As one of the professional tantalum tube manufacturers, the tantalum tubes produced by Aulister have high value in various industrial and technical applications. Made from the metal element tantalum as raw material, they have strong corrosion resistance, good thermal conductivity, and excellent resistance to acids and liquid metals, making them widely used in the semiconductor industry.
