On July 4, 2023, the Ministry of Commerce and the General Administration of Customs jointly issued a notice to implement export control on gallium and germanium related items. Among the germanium-related items whose exports are restricted are: germanium metal, zoned germanium ingots, zinc germanium phosphate, germanium epitaxial growth substrates, germanium dioxide and germanium tetrachloride.

According to China Tungsten Online, on July 4, 2023, the Ministry of Commerce and the General Administration of Customs issued an announcement on the export control of gallium and germanium related items. According to the announcement, there are 8 gallium related items, namely gallium metal (monomer), gallium nitride, gallium oxide, gallium phosphide, gallium arsenide, indium gallium arsenic, gallium selenide and gallium antimonide; 6 germanium related items, namely germanium metal, zoned germanium ingot, zinc phosphor germanium, germanium epitaxial growth substrate, germanium dioxide and germanium tetrachloride; the export control will be effective on August 1.

Analysis of latest tungsten market from Chinatungsten Online

At the beginning of the week, China tungsten price continued to be stable affected by the low trading activity of market participants. 

The reason why tungsten needles can be used in microscopes is that they have some special properties and characteristics that make them suitable for various applications in microscopes. Here are some reasons: 

Tungsten needles are made from the material with high melting, high density, good corrosion resistance and electrical conductivity. They can be used for several applications in microscopy. Specifically, the following are common applications: 

Analysis of latest tungsten market from Chinatungsten Online

In the first half of 2023, China tungsten market generally fluctuated in a range because the macroeconomic environment was under pressure, and the fundamentals of supply and demand continued to be in a stalemate. 

At the beginning of the week, China rare earth market is still sluggish. In addition to the continuous decline in the prices of some light and heavy rare earth raw materials, the prices of different grades of NdFeB blanks and their scraps also dropped. 

At the beginning of the week, Chinese molybdenum prices moved down slightly mainly due to the decrease in market demand and the increased awareness of profit-taking among many suppliers. 

Tungsten copper alloy combines the advantages of copper and tungsten, with the advantages of high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical and thermal conductivity and good processing performance.

Tungsten copper alloy is an alloy composed of two metals, tungsten and copper. Tungsten is a metal with a high melting point and high density, as well as excellent thermal conductivity and high strength. Copper has good electrical and thermal conductivity and is a commonly used electrical material.
