Tantalum Sheets & Plates have high density, exceptionally high melting points, and good resistance to all acids except hydrofluoric acid at average temperatures. Although tantalum is not just a noble metal, it has chemical resistance similar to the above metals. The Tantalum Alloy Sheets resist chemical attack to a great extent, up to 302 degrees Fahrenheit or 150 degrees Celsius. One reason they've become so crucial in miniaturizing personal electronic devices is because they inherently fight corrosion.
Tantalum Alloy Plates do not corrode and are easily malleable and thus find significant applications in medical uses like cranial defect replacements, wire sutures, and prosthetic devices. Tantalum may be cold-drawn into fragile wires. A considerable quantity of it is used for metal evaporation, particularly aluminum. It's the property to form a protective oxide layer that makes Tantalum Alloy Coils very resistant to corrosion by most acids. However, they have an acidity problem with hydrofluoric acid and molten alkalis. It has a melting point only exceeded by tungsten and rhenium, again pointing toward the unique properties of tantalum under extreme conditions.
