Tantalum Ta-Nb20 Fasteners Manufacturer & Supplier
The Tantalum Ta-Nb20 Fasteners are specially designed to provide efficient fastening and fixing. The fastener is made from a Tantalum-Niobium alloy of which 20% is Niobium. These high performance fasteners have a wide application, they are strong in terms of wear and corrosion resistant; also possess the characteristic to be in high temperature range and have good ductility. The common applications include aerospace, chemical processing, nuclear, marine and other high temperature industrial needs. The Tantalum Ta-Nb20 Alloy Fasteners can be acquired in the shape of Bolts, Nuts, Screws, Washers, Studs, Threaded rods, and custom made fasteners as per ASTM B365 TANTALUM FASTENERS specification.
Tantalum Ta-Nb20 Fasteners Manufacturer, Supplier and Exporter
We are a leading manufacturer, supplier and exporter of Tantalum Ta-Nb20 fasteners. Tantalum Ta-Nb20 fasteners are engineered to operate efficiently under severe industrial applications such as in the presence of intense heat, reactive chemicals and immense mechanical loads. Their composition consists of nearly 80% tantalum and 20% niobium. This provides exceptional corrosion resistance and increased tensile strength and thermal stability.
Tantalum alloy fasteners are sought after in various applications that demand superior durability. Conventional stainless steel and nickel alloys are not sufficient to handle the stress and environments under which these tantalum fasteners will operate. All of our fasteners are produced through advanced manufacturing techniques and are tested for high quality. This guarantees consistent performance. We work with industrial specifications and international standards.
We supply a variety of Tantalum Ta-Nb20 alloy fasteners that includes, but is not limited to: bolts, nuts, washers, threaded rods, hex screws, socket head cap screws, studs, and more specialized fastener systems.
What are Tantalum Ta-Nb20 Fasteners?
Tantalum Ta-Nb20 Fasteners are designed specifically as fasteners and made with an alloy of tantalum and niobium that provides both superior corrosion resistance and a high-temperature capability. The inclusion of niobium improves the mechanical strength over that of tantalum pure and offers continued excellent corrosion resistance against acids, chlorides, and oxidizing media.
They are particularly suitable for applications where they will be exposed to:
- Concentrated sulfuric acid
- Hydrochloric acid systems
- Nitric acid processing
- Aerospace engine assemblies
- High-vacuum systems
- Nuclear reactors
- Heat exchangers
- Semiconductor manufacturing equipment
The ASTM B365 TANTALUM FASTENERS are typically used on systems that can tolerate no failure.
