Why Should I Use Tantalum in Corrosive Environments?
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
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 […]
Choose the Right Tantalum Rod for your Application
If you need a metal rod that can withstand high temperatures and has extremely strong chemical resistance to most corrosive environments then tantalum rod is already on your short list of materials. Tantalum belongs to a class of metals known as refractory metals, which are defined by their strong resistance to heat and wear. It […]
Facts about Tantalum
Tantalum (Ta) is an unsung hero in modern metallurgy. First discovered by the Swedish chemist Anders Ekeberg in 1802, this versatile metal has become essential to numerous industries over the years. Raw tantalum rarely occurs in nature. Instead, it is typically found in the ore columbite-tantalite (usually referred to as coltan). Once extracted, pure tantalum […]
Tantalum Prices are Climbing… So What Can You Do About It?
If you buy tantalum, you have surely noticed that tantalum prices are climbing. That’s because demand for the versatile gray metal is quickly escalating. The latest forecasts from industry leaders predict a 4-7 year increase in demand and higher market prices for the ore, capacitor powder, melt stock and mill products. As smartphone and electronics […]
Save Money by Improving Tantalum Yields
Let’s face it, if you’re buying tantalum, it’s probably because you have no choice. Your application likely demands one of the robust characteristics of the metal, such as the unmatched corrosion resistance, or the magnetic shielding properties, or maybe it’s the extremely high melting temperature. Regardless of why you need it, tantalum is always expensive […]
Hafnium – It’s Elemental
Hafnium is element 72 on the periodic table. It is a tetravalent transition metal colored silver gray and is often found in zirconium, its sister element. Discovered in 1923 in Copenhagen, it was named after the city’s Latin name, Hafnia. Hafnium is used in many industries and hi-tech applications. Some of these include: coatings of […]
Why You Should Not Buy Tantalum from an Inexperienced Reseller
When you call your local metal supplier and ask for a coil of tantalum sheet or a plate of niobium, do they ask you about your application? Do they ask you what type of machining you will be performing or if you’re drawing parts from this material? These are examples of important questions to […]

Since 1997, Admat has been supplying Tantalum powders and mill products to a variety of industries. Over the years, Admat has become one of the largest sources of refractory metals in the US. Now they have partnered with […]
The Value of Tantalum Experience
Tantalum is expensive. For most users of Tantalum, it is likely the most expensive material they buy. It’s for that reason that so many companies source their material from smaller mills overseas to avoid paying the higher prices charged by the big American mills. But with so many companies selling tantalum, how can you tell […]
