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 […]

How Titanium Is Used Today?

0 Comment

How Titanium Is Used Today? In today’s article, we’ll take a look at how titanium is used today. Titanium is a hard, shiny, and strong metal. It is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including molybdenum, aluminum, and iron. Titanium metal connects well with […]

When Was Tungsten First Used in Light Bulbs

0 Comment

More than 350 years ago, porcelain makers in China incorporated a unique peach color into their designs by means of a tungsten pigment that was not known in the West. Indeed it was not for another century that chemists in Europe became aware of it. In 1779, Peter Woulfe examined a mineral from Sweden and […]

Why Is Molybdenum A Good Conductor of Electricity?

0 Comment

Why Is Molybdenum A Good Conductor of Electricity? High-tech metals are called refractory metals in scientific terms, with a high melting point of 3500 degrees C. Tungsten, molybdenum, tantalum, and niobium are refractory metals. The characteristics of these materials are not only high melting points but also difficult to mine and process. A special process beyond […]

Refractory Alloy Sintering Process

0 Comment

Refractory Alloy Sintering Process In today’s article, we’ll take a look at the refractory alloy sintering process. Refractory alloy sintering can be divided into six stages. Refractory Alloy Sintering Process – 1. Agent Removal & Burning Stage With the rising temperature, the molding agent gradually decomposes or vaporizes with the sintered body left. At the same time, […]
