FAQ

Q: Why is tantalum special?

A: Tantalum alloys can be extremely strong and have been used for turbine blades, rocket nozzles and nose caps for supersonic aircraft. Tantalum has no known biological role. It is non-toxic. Tantalum is sometimes, but only rarely, found uncombined in nature.

Q: What are the three main uses of tantalum?

A: It finds its applications in the field of high-temperature devices such as in the engines of aircraft.
It is used mainly as an alloying medium as it is helpful for hardening metals.
It is employed in the manufacture of capacitors.
It has a high number of medical as well as dental applications.

Q: What are the properties of tantalum material?

A: Tantalum material is dark (blue-gray), dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is highly resistant to corrosion by acids: at temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia.

Q: What is the difference between tantalum bars and rods?

A: Tantalum rods are typically flat or rectangular with a greater width and thickness, providing a larger surface area. In contrast, tantalum rods are cylindrical, longer, and thinner, resembling a stick which ideal for precision tasks.

Q: Is there a limit to the length or diameter of a tantalum rod?

A: The length and diameter of a tantalum rod can be tailored to meet specific needs, although there may be practical limits based on manufacturing capabilities.

Q: How do I determine the right tantalum rod for my application?

A: Choosing the right tantalum rod depends on your specific application requirements, including size, strength, temperature, and corrosion resistance needs.

Q: What certifications do your tantalum rods come with?

A: Our tantalum rods typically come with certifications that confirm their quality, purity, and compliance with industry standards. Specific certifications can be provided upon request.

Q: How are tantalum rods shipped and stored?

A: Tantalum rods are usually shipped with protective packaging to prevent damage. They should be stored in a dry environment to maintain their integrity.

Q: What is the lead time for an order?

A: Lead times vary based on order size and specifications. We strive for prompt delivery.

Q: What is the composition of niobium C103?

A: C-103, which is 89% Nb, 10% Hf and 1% Ti, is used for the rocket nozzle of the Apollo service module and the Merlin vacuum engines; it is regarded as a medium-strength alloy.

Q: How is niobium-hafnium alloy C103 rod manufactured?

A: The manufacturing process typically involves vacuum arc melting or electron beam melting to ensure precise control over the alloy composition and microstructure.

Q: How does niobium-hafnium alloy C103 rod perform at high temperatures?

A: This alloy exhibits exceptional performance at temperatures exceeding 1,000°C, maintaining its structural integrity and mechanical properties under extreme conditions.

Q: Can niobium material get wet?

A: Niobium material can withstand harsh washdown scenarios and is resistant to all chemicals. It is hypoallergenic and will not corrode under any conditions.

Q: Does niobium material dissolve in water?

A: Niobium material is not attacked by nitric acid up to 100 °C but is vigorously attacked by the mixture of nitric and hydrofluoric acids. It is unaffected at room temperature by most acids and by aqua regia. It is attacked by alkaline solutions, to some extent, at all temperatures. Niobium becomes a superconductor at 9.15 °K. It is insoluble in water, hydrochloric acid, nitric acid and aqua regia; soluble in hydrofluoric acid; and soluble in fused alkali hydroxide.

Q: What are 3 important uses of niobium?

A: Alloys containing niobium are used in jet engines and rockets, beams and girders for buildings and oil rigs, and oil and gas pipelines. This element also has superconducting properties. It is used in superconducting magnets for particle accelerators, MRI scanners and NMR equipment.

Q: Is niobium magnetic or not?

A: Niobium, due to its variety of properties, is used in several areas of research. One such research is in creating magnets.
