Among the different grades of tantalum plates, the ASTM B708 R05252 Tantalum Plates stand out for their exceptional qualities. At ASC LLP, we are proud to be recognized as leading exporters and suppliers of ASTM B708 R05252 Plates, catering to the needs of industries worldwide.
What Are ASTM B708 R05252 Tantalum Plates?
ASTM B708 R05252 Tantalum Plates are high-purity tantalum plates that conform to the specifications laid out by the ASTM B708 standard. This standard governs the requirements for wrought tantalum and tantalum alloy plates, sheets, and strips, ensuring they meet the highest quality and performance criteria. The R05252 grade is known for its exceptional purity and mechanical properties, making it suitable for applications where both corrosion resistance and durability are critical.
The ASTM B708 R05252 Tantalum Plates are manufactured through a meticulous process that includes rolling and annealing, resulting in plates with uniform thickness and superior surface finish. These plates are widely used in industries such as chemical processing, electronics, and aerospace, where the performance of materials under extreme conditions is paramount.

Properties of ASTM B708 R05252 Tantalum Plates
One of the key factors that make R05252 Tantalum Plates highly sought after is their unique set of properties. Some of the most notable properties include:
- Corrosion Resistance: Tantalum is renowned for its resistance to corrosion, particularly in acidic environments. The ASTM B708 R05252 Tantalum Plates exhibit excellent resistance to a wide range of corrosive substances, including hydrochloric acid, sulfuric acid, and nitric acid, making them ideal for use in harsh chemical environments.
- High Melting Point: With a melting point of approximately 2996°C, tantalum is one of the most refractory metals. This property allows plates Tantalum ASTM B708 to maintain their structural integrity even at extremely high temperatures, making them suitable for high-temperature applications.
- Biocompatibility: Tantalum is biocompatible, meaning it is non-toxic and does not cause adverse reactions when in contact with biological tissues. This property makes R05252 Tantalum Plates suitable for use in medical implants and devices.
- Ductility and Malleability: Despite its high strength, tantalum is highly ductile and malleable. The ASTM B708 R05252 Tantalum Plates can be easily formed into complex shapes without cracking, which is crucial for custom applications.
- Thermal and Electrical Conductivity: Tantalum exhibits good thermal and electrical conductivity, which is beneficial in applications that require efficient heat and electrical transfer.
