These fasteners offer excellent high-temperature stability, and tantalum has an exceptionally high melting point of about 3000°C. When working at high temperatures, vacuum or inert gas conditions must be used since tantalum embrittles at above 250°C in oxygen. Tantalum is also known for its very excellent properties in biocompatibility and radiopacity; it has a very high density of 16.68 g /cm³.
Sankalp Alloys Overseas provides tantalum fasteners in commercially pure tantalum and tantalum 2.5% tungsten, Ta-2.5%W alloys. Tantalum is an exceptional metal with extraordinary density, malleability, hardness, and excellent thermal and electrical conductivity. It has very high resistance to chemical attack at room temperature. It has a melting point as high as 5,425°F makes this metal a cost-effective alternative to platinum in many applications.
Mechanically, tantalum is very ductile; hence, it will resist bending, stamping, and pressing without losing its integrity. We guarantee that our Tantalum Fasteners adhere to strict quality standards through rigid tests and inspection procedures to give maximum reliability and performance in diverse industries and medical applications with newer possibilities. Sankalp Alloys Overseas strives to present superior products and outstanding service in return for customer satisfaction for every Tantalum Fastener supplied.
