Tantalum rods are cylindrical materials made of tantalum metal. It usually has a uniform diameter and length. This rod-shaped material usually possesses the unique properties of tantalum metal, such as high melting point, thermal stability and good corrosion resistance, and can be used in various industrial and technical applications. Our tantalum rods can be customized in sizes and grades as per customer requirements. To meet the diverse needs of structural design and engineering, we also offer various types of bars including flat, round, square and hexagonal bars.

In addition to commercial pure tantalum, Edgetech also supplies medical grade tantalum and tantalum alloys Ta2.5%W, Ta7.5%W, Ta10%W, Ta40% niobium (niobium).

Tantalum rods are typically supplied in compliance with the requirements of ASTM-B-365, ASTM-F-560, AMS 7848, ISO 13782, R05200, R05400, R05255, R05252, R05240.

Advantages and Applications of Tantalum Materials

Tantalum Rectangular Bar

Material properties

Tantalum is a corrosion-resistant, high-melting-point, high-density metal. It has excellent corrosion resistance and has good resistance to corrosive media such as strong acid and strong alkali.

High melting point

Tantalum has a very high melting point of about 3017 degrees Celsius (5463 degrees Fahrenheit). This allows tantalum to remain stable in high-temperature environments, making it suitable for applications in high-temperature processes and special environments.

Thermal Conductivity

Tantalum has good thermal conductivity, which allows tantalum rods to be used in some applications that require high thermal conductivity, such as thermally conductive components in semiconductor manufacturing.

Mechanical behavior

Tantalum rods have moderate mechanical properties and can be tailored to meet the requirements of specific applications with appropriate processing and handling. This makes it very useful in manufacturing various industrial parts.

Tantalum rod packaging

Our tantalum rods are carefully processed to prevent damage during storage and transportation and to maintain the original quality of the product.
