Niobium

Niobium and Niobium Alloys

Niobium is the ideal material for metal stamping because of its ductility, high durability and stability. With 50 years of experience, Standard Die, has mastered the process of shaping Niobium in low temperatures. It’s often used for aerospace applications because it is a very drawable metal that is ductile at room temperature, but strong at high temperatures with a high melting point. It is relatively lightweight, has good corrosion resistance and boasts a unique resistance to radiation damage. Niobium is also a superconductor material.

Metal fabricators and stampers love niobium because it is naturally hypoallergenic and resistant to corrosion. Standard Die has been an industry leader and metal stamping pioneer since 1970, during which time we’ve mastered the use of niobium. It’s currently our most commonly used material. Niobium makes up a large part of the metal supplies that serve industries across the globe.

How Niobium Is Used in Metal Stamping

A wide range of parts requires niobium metal stamping, from lightweight and hypoallergenic items to ultra-strong superconducting magnets. Its most common use, however, is in making mixed metal alloys. When combined with steel, for example, it can make an incredibly strong and high temperature-resistant nuclear reactor. For similar reasons, it’s often a favorite for transportation — from airplanes and space vehicles to skateboards.

Niobium is also Standard Die’s most commonly used material. We’ve mastered the use of niobium from niobium part fabrication to deep drawn products.

From Medical to Aerospace, Many Industries Rely on Niobium

Niobium’s unique combination of flexibility and durability make niobium part fabrication highly desired by many industries. Industries that frequently use niobium include:

  • Electronics: Because of its high melting point, niobium is a favorite for use in laser technology, electronic vacuum devices and more.
  • Nuclear: The nuclear industry often uses niobium as an accelerator magnet or as magnetic energy storage.
  • Medical: Its hypoallergenic qualities make it less likely to irritate patients with titanium medical implants.
  • Welding: Its pliable nature gives welders and stampers more control in their craft.
  • Construction: Because of its strength, niobium is often used for pipeline construction, in addition to transport construction such as automobiles and ships.
  • Jewelry: Niobium is commonly used to craft special jewelry that is less likely to irritate wearers with sensitive skin.
  • Aerospace: The aerospace industry most commonly uses niobium. This is because niobium is considered the ultimate metal to withstand high temperatures without weakening, making it ideal as the alloy for manufacturing jet engines and components of rockets and spacecraft.

About Standard Die

FOUNDED IN 1970

When Al Menzies Sr. established Standard Die over 50 years ago, his plan was simple: stand out from the competition. As the first metal stamper to the industrial diamond industry, he was unwilling to compromise his values. He made sure integrity, customer service and quality were integrated into every aspect of the business and, as a result, designed and manufactured some of the world’s finest products for the industrial diamond industry.

Our Mission:
“To make the purchasing of metal stampings painless.”

By pursuing this mission for more than four decades, we have grown from a start up tool and die operation to a world-class metal stamping company. With more than a billion parts delivered, we have provided precision drawing and stamping services to customers spanning the industrial diamond, automotive, aircraft, electrical and medical industries across the globe.
