Tungsten metal can be bent and formed, but it presents significant challenges due to its physical properties. Tungsten is known for its extremely high melting point (about 3,422°C or 6,192°F) and exceptional hardness, which makes it difficult to work with at room temperature. Best results are achieved by bending across the grain as pure tungsten […]
Precision machining of pure tungsten is challenging due to its unique physical properties. Tungsten has a very high melting point (around 3,422°C or 6,192°F), excellent hardness, and brittleness at room temperature, which make it difficult to machine using conventional methods. Produced via the powder metallurgy process, pure tungsten metal exhibits stratified layers and grain directions […]

Tantalum Properties Tantalum (pronounced tan-ta-lum) is number 73 on the periodic table. Rarely occurring in nature, tantalum is typically found in the ore columbite-tantalite. When refined, pure tantalum metal is a lustrous blue-gray color, similar in color to platinum. Pure Tantalum: Tantalum has one of the highest melting and boiling points of all the chemical […]
Why Does The United States Have Export Controls? Certain destinations, organizations and individuals are subject to trade sanctions, embargoes and restrictions under U.S. law. The United States has export controls in place to protect national security interests and to promote its foreign policy objectives. The U.S. also participates in various multilateral export control regimes to […]
Niobium (Atomic number 41), is a greyish-silvery metal. It is a transition metal found in group 5 & period 5 on the periodic table. A fairly dense & ductile element, Niobium is similar to tantalum and found just above it on the periodic table. In fact, both niobium and tantalum are found together in the […]
