Spherical Tantalum-Tungsten Alloy Powder
A tantalum alloy formed by adding a certain amount of tungsten to a tantalum base. The Ta-W binary alloy system is an infinite solid solution. As tungsten content is increased, the strength of the alloy increases. When it exceeds 12–14 at.%, the plasticity of the recrystallized alloy decreases significantly. Spherical tantalum-tungsten alloy powders that are commercially available are Ta-2.5W, Ta-7.5W, and Ta-10W. These alloys retain the low-temperature ductility of unalloyed tantalum and are more resistant to oxidation and stronger.
Since tantalum-tungsten alloys are stronger than unalloyed tantalum and retain the same corrosion resistance, they find extensive uses in the chemical and aerospace industries.
- Ta-2.5W alloy: Primarily used in heaters, cooling coils, heat exchangers, and reactors.
- Ta-7.5W alloy: Predominantly used as spring materials and other corrosion-resistant elastic components for chemical processing equipment.
- Ta-10W alloy: Suitable for high-temperature applications such as liquid rocket engine thrust chambers (having temperatures above 3300°C) and heating elements for vacuum furnaces.
