Tantalum Foil - T 0.05mm 80mm x 135mm

Details

SKU: 1000175888 Product Code: TA00-FL-000260
Designed for extreme environments, Goodfellow's Tantalum Foil combines ultra-high purity (up to 99.999% Ta) with exceptional durability - ideal for vacuum systems, furnaces, electronics, aerospace, and nuclear applications. Available in tight thickness ranges from 0.0005 mm to 6 mm and lengths and widths up to 500 mm, it integrates seamlessly into assemblies where precision, quality, and repeatability matter. Tantalum’s exceptional corrosion resistance stands up to hot acids and aggressive environments, making it an ideal material for reactor liners, semiconductor fabrication, and heat exchanger components. Its high melting point and malleability allow reliable performance in furnace linings and thermal shield wraps. In electronics, foil anodes and tantalum oxide sputter targets provide high capacitance, low leakage, and stable dielectric properties. Biocompatible and nontoxic, it’s also trusted in thin surgical meshes, implantable electrodes, and medical feedthroughs. For any application where longevity and performance under stress are critical, our tantalum foil delivers.
