In order to avoid environmental pollution caused by military materials, tungsten alloy military products are gradually replacing lead and depleted uranium for bullets and armor-piercing bullets. In the military field, tungsten alloy military products are gradually becoming popular.
Nuclear batteries are also called "radioisotope batteries", or isotope batteries for short. It uses semiconductor transducers to convert the heat energy continuously released by radioisotopes in the decay process into electrical energy.
China tungsten price was in the upward trend in the week ended on Friday July 31, 2020, but affected by the weakness both in the supply and demand sides, transactions were poor at the end of this month.
The international research team conducted characteristic research and analysis of the "cobalt/molybdenum disulfide heterostructure" and found that this new material combination is expected to lead semiconductors to break through the physical limits and become a potential new star.
Because recrystallization TZM alloy at room temperature is fragile and it is hard to deform. So before cool and warm rolling should avoid annealing at perfect recrystallization.
Both cast flanges and forged flanges are commonly used flanges. The cast flanges have accurate rough shape and size, small processing volume, low cost, but have casting defects
X-ray protection tungsten alloy baffle refers to a tungsten alloy plate made of tungsten-nickel-iron alloy or tungsten-nickel-copper alloy, and its X-ray protection effect is better than that of traditional lead block.
TZM alloy has good high temperature mechanical property, but at a high temperature oxidation resistance property is poor. Under high temperature, it unable to form a protective oxide layer, so it must be used at high temperatures in non-oxidizing atmosphere. When the temperature is below 400 ℃
