Tantalum Round Bar
Talk To Us – We’re Here To Help
Solitaire Steel is a leading manufacturer of Tantalum Bars, which are a type of refractory metal, similar to molybdenum and tungsten. Tantalum round bars are highly regarded for their exceptional corrosion resistance, especially against acids. They remain unaffected by aqua regia at temperatures below 150 °C, making them suitable for various demanding applications.
Tantalum rods are known for their ductility, allowing for easy fabrication. They also conduct heat and electricity well, forming a protective oxide layer that helps prevent further reactions with corrosive substances. With a high melting point and impressive strength, tantalum alloy round bars are widely used in the production of electrical components like capacitors and high-power resistors. Additionally, they are employed in making alloys and superalloys due to their excellent physical properties.
Tantalum alloy bars are often mixed with other metals to create carbide tools. While tantalum is highly inert, it can react with hydrofluoric and sulfuric acids, and it is also susceptible to corrosion by alkaline solutions. The melting point of tantalum alloy rods reaches 2996 °C, and they exhibit outstanding corrosion resistance across most acid combinations.
Our tantalum products can be easily worked at room temperature and have high thermal conductivity. These unique properties make tantalum bars essential for specific applications, justifying their higher cost. We offer various sizes and shapes to meet our clients’ specific needs.
