What is ASTM B521 R05200 Tantalum Flanges?
ASTM B521 R05200 Tantalum Flanges are flanges made from tantalum, a rare and highly corrosion-resistant metal. The designation “ASTM B521” refers to the American Society for Testing and Materials (ASTM) standard specifically governing the specification for tantalum and tantalum alloys used in the manufacturing of flanges and other components. The R05200 grade indicates the specific composition and properties of tantalum as defined by this standard.
Tantalum flanges are used to connect pipes, valves, pumps, and other equipment in various industries, including chemical processing, aerospace, and pharmaceuticals. Due to their unique properties, ASTM B521 R05200 Tantalum Flanges are an ideal choice for applications where conventional materials would fail due to corrosion, heat, or pressure.

Properties of ASTM B521 R05200 Tantalum Flanges
The ASTM B521 R05200 Tantalum Flanges possess several key properties that make them suitable for demanding applications:
- Corrosion Resistance: Tantalum exhibits exceptional resistance to corrosion from acids and other aggressive chemicals. This makes it ideal for use in chemical processing environments where other materials might corrode quickly.
- High Melting Point: Tantalum has a melting point of approximately 3017°C (5463°F), which allows it to maintain its structural integrity even at elevated temperatures.
- Ductility and Malleability: Tantalum is highly ductile and malleable, allowing it to be easily formed into complex shapes without compromising its properties.
- High Strength: Despite its lightweight nature, tantalum is known for its high strength-to-weight ratio, providing durability and resilience in demanding applications.
- Biocompatibility: Tantalum is biocompatible, making it suitable for medical applications, including implants and devices that come into contact with bodily fluids.
- Excellent Electrical Conductivity: Tantalum is a good conductor of electricity, which can be beneficial in certain electronic applications.
