Product Description

Tantalum foil ASTM B708 Ta foil 0.025mm Detailed introduction

Tantalum foil is a thin sheet material made of high-purity tantalum metal, with a thickness of 0.025mm, conforming to the international standard ASTM B708. This standard imposes strict requirements on the chemical composition, mechanical properties, dimensional tolerances, and surface quality of tantalum and tantalum alloy plates, strips, and foils. Tantalum, a rare refractory metal, possesses excellent corrosion resistance, a high melting point, high ductility, and good biocompatibility, and is widely used in high-end fields such as electronics, chemicals, aerospace, and medicine.

Tantalum Foil Quality Assurance

Standardized Production: Strictly adheres to ASTM B708 international standards; all products undergo chemical composition analysis and mechanical property testing.

High-Purity Raw Materials: Employs vacuum electron beam melting technology to ensure high metal purity and low impurity content.

Surface Quality Control: Foil surfaces are smooth and bright, free of cracks, indentations, and inclusions.

Testing and Traceability: Each batch of tantalum foil comes with a Certificate of Account (COA) and quality inspection report, supporting third-party testing.

Packaging and Transportation: Uses anti-static paper, vacuum packaging, and moisture-proof treatment to ensure protection against oxidation and contamination during transportation.
