Tantalum has a unique property combination of high ductility, superior biocompatibility as well as having a high melting point and being the most corrosion-resistant metal in common use today.

Tantalum (High-strength, ductile and corrosion resistant)

Product Information

Elementum 3D’s pure tantalum material is a high strength, heavy, and hard refractory metal with excellent ductility. At temperatures below 302°F (150°(), it is nearly completely immune to chemical attack. Tantalum applications are typically found in aerospace, medical, nuclear and electrical industries.
