Refractory Metal Powders VS 3D Printing Technology

0 Comment

Refractory Metal Powders VS 3D Printing Technology 3D printing technology is also called additive manufacturing, and the metal devices produced by this technology are somewhat similar to the powder gold treatment technology we currently use, all of which are built on metal powder, and the difference is that the material powder is not bonded by […]

Why Is Zirconium A Transition Metal?

0 Comment

Why Is Zirconium A Transition Metal? When of sufficient purity, zirconium is soft and ductile. Zirconium a transition metal has good corrosion resistance and low absorption capacity for thermal neutrons. These properties are desirable in materials used for certain parts of nuclear reactors. The great increase in the production of zirconium since 1945 has been […]

How Does Chromium Work?

0 Comment

How Does Chromium Work? In this article, we will take a look at how chromium works. The melting point of chromium is the lowest of the abundant refractory metals, but it is more than 700 degrees above that of iron. The density of chromium is slightly less than that of iron. At elevated temperatures, it […]

The List Of Abundant Refractory Metals

0 Comment

The List Of Abundant Refractory Metals Tungsten, tantalum, molybdenum, columbium, vanadium, and chromium may be classed as relatively abundant refractory metals; that is, free world reserves of contained metal are over 100,000 tons for each metal. The first four show promise in a considerably higher temperature range than the last two, and sometimes the term […]

Which Metals are Nickel Free?

0 Comment

Which Metals are Nickel-Free? In 1751, Axel Fredrik Cronstedt, working at Stockholm, investigated a new mineral – now called nickeline (NiAs) – which came from a mine at Los, Hälsingland, Sweden. He thought it might contain copper but what he extracted was a new metal which he announced and named nickel in 1754. Many chemists […]
