The particularity of products in the aerospace sector lies in the need to adapt to extreme environments (eg dry and thin atmosphere, high temperature, abrasion). Parts treated with chemical vapor deposition ensure equipment durability and safety. Our custom tantalum metal parts in particular improve the dynamics of the system and meet the extremely stringent conditions in this field.


Tantalum has special applications in the aerospace industry, especially in engines, based on superalloys (also known as superalloys) and heat-resistant alloys based on tantalum. Adding tantalum to nickel-based, cobalt-based, and iron-based alloys can produce high-performance alloys such as superalloys, corrosion-resistant alloys, and wear-resistant alloys.


Compared with niobium-containing superalloys, tantalum-containing superalloys have superior performance, higher heat resistance and higher stress loads. The tantalum-based heat-resistant alloys are divided into two series, TaW and Ta-Nb, and other additives include molybdenum, hafnium, and rhenium. These alloys have excellent properties, such as Ta-W-Hf alloys with high high temperature strength (1650 ℃ or higher) and creep resistance, good low temperature plasticity and welding performance. These alloys are mainly used as heat-resistant and high-strength structural materials for supersonic aircraft, solid propellant rockets, missiles, and parts for control and adjustment devices.


The aerospace industry is the second largest user of niobium and tantalum. Alloys of niobium and tantalum, especially their superalloys and heat-resistant alloys based on them, are indispensable pillar materials in the hot parts of aircraft jet engines, rockets, spacecraft and other vehicles. The four major refractory metals, tungsten, molybdenum, tantalum, and niobium, are called space metals.
