Tantalum R05255 Sheets and Plates are top-notch, corrosion-resistant materials designed for the toughest environments, where reliability and durability are a must. These sheets and plates are made through a precise alloying process, incorporating a bit of tungsten to boost their strength and thermal stability. Sourced from specialized metal suppliers in Bangkok, Thailand, Tantalum R05255 products comply with ASTM B708 standards and are highly sought after in advanced chemical processing, electronics, and aerospace sectors. With their impressive workability, biocompatibility, and resistance to harsh chemicals, these plates provide a trustworthy solution for demanding applications that require both durability and precision in extremely corrosive and high-temperature conditions.
Tantalum R05255 is an alloy that consists of about 97.5% tantalum and 2.5% tungsten, which enhances its strength and creep resistance compared to pure tantalum (R05400). It maintains excellent corrosion resistance, particularly in strong acids like hydrochloric, nitric, and sulfuric acid. The alloy boasts a tensile strength ranging from 300 to 550 MPa and a yield strength of around 200 to 400 MPa, depending on the temper and processing. Elongation typically falls between 20% and 30%. Tantalum R05255 has a high melting point close to 3000°C and offers good ductility and weldability. The addition of tungsten enhances structural stability at elevated temperatures while keeping corrosion resistance intact.
