When To Consider Using Tungsten Heavy Alloys

Comments Off on When To Consider Using Tungsten Heavy Alloys

Tungsten heavy alloys (WHAs) are often used instead of pure tungsten because they have a significantly higher density and improved mechanical properties. Pure tungsten is relatively brittle and has a low density compared to other metals, which makes it difficult to work with and limits its applications. WHAs are made by alloying tungsten with other […]

Why Tantalum Capacitors Are Essential in Modern Electronics

Leave a Comment

Tantalum capacitors were first invented in the early 20th century by a Polish engineer named Wawrzyniec Lewicki. He discovered that tantalum oxide was an excellent dielectric material, meaning it could hold an electric charge without conducting electricity. This property made it possible to create tantalum capacitors, which were significantly smaller and more reliable than existing […]

Facts About Niobium: Production, Properties, Applications, and Availability

Leave a Comment

Niobium – the 41st element on the periodic table– is a soft, grey, crystalline metal used in a variety of applications from steel production to hypoallergenic jewelry. The metal was originally discovered by British chemist Charles Hatchett in 1801 as he examined American minerals from a collection in the British Museum. Hatchett named this element columbium, after Christopher Columbus.  Through the years most people now refer to this element as Niobium.  As tantalum and niobium are often found together and […]

Why Should I Use Tantalum in Corrosive Environments?

Leave a Comment

Refractory metals are metallic elements that exhibit properties that make them more durable than other metals. For example, they can demonstrate corrosion resistance, thermal and electrical conductivity, and deformation resistance. These characteristics make them ideal for use in highly demanding applications and environments. One example of refractory metals is tantalum, which is prized for its […]

The Characteristics and Manufacturing Process of Tantalum and Niobium

Leave a Comment

Tantalum and niobium are transition metals that are commonly found together in nature. They are often difficult to separate from one another due to their similarities in physical and chemical characteristics. In fact, when tantalum was first discovered in 1802, it was confused with niobium, which was discovered much earlier in 1734. It was not […]
