There must be a knife in the engraving, and the engraving knife is an extremely important tool for engraving the seal. For the primary printing friends, the tungsten steel knives can be said to be more suitable for quick start “knife pen”. It can be your partner on the road, accompanying you and growing up with you. For the old Indian friends, it is like an old friend. Of course, I believe that the Indian friends also know that the…

It is well known that tungsten (W) is the purest metal with the highest melting point in the world (meaning it is the most difficult to melt), and its melting point is 3156.85 Kelvin (3430 ° C). At present, the most refractory material in the world is a powder mixture of bismuth-containing carbides and nitrides, which has a melting point of 4400 Kelvin (4126.85 ° C). This was synthesized a few days ago by Russian Far Eastern Federal University and…

Technology products such as smartphones, electric cars, big-screen TVs, and green energy power generation rely on a range of chemical elements that most people have never heard of. Until the end of the 20th century, people were only curious about these high-tech products. But nowadays, I feel that it is uncomfortable to find out which one is missing. This also reflects from the side that these chemical elements are indispensable. Because, in fact, a single mobile phone contains more than…

The Boeing 787 “Dream Window” does not have a visor, but it can change the transmittance. What is similar to this is the tungsten oxide electrochromic film. The porthole of the Boeing 787 has no visor, but it can change the transparency! You only need to press the button, the porthole will become a “chameleon” until it is completely darkened! Of course, the captain can also dim directly from the cockpit when the night falls. In addition, because the color…

In today’s rapid development of the IT industry, the chip can be described as the brain of various data analysis, is the core! Now, for high-purity sputtering targets, the highest-end application area is the field of ultra-large-scale integrated circuit chip manufacturing, which is actually a field of semiconductor chips, and also occupies a large market share. Moreover, the market capacity of semiconductor chips in the future will be further enhanced with the continuous growth of semiconductor chip demand in the…

Smart home makes our home life more comfortable, safer and more convenient! It is also energy-saving and environmentally friendly, and it also makes our life quite artistic. Therefore, the emergence of a smart sun room is not surprising. The so-called intelligence, one of them is to break the sun room in the summer like a “fire stove”, winter like a “refrigerator”. The role of this is transparent semiconductor materials, such as tungsten oxide transparent insulation materials, can make the sun…

Steel fishing needles added the elements of tungsten and vanadium – with lighter weight, harder and sharper. This is the first time that tungsten and vanadium elements have been introduced into fishing needles, and the advent of this technology will bring about a milestone change in the fishing needle industry. Undoubtedly, this type of fishing needle is harder and more wear-resistant than the fishing needle made of ordinary steel wire. What’s more, this number of fishing needles is available to…

Are you in the heat of the northern hemisphere? Still in a corner of the southern hemisphere? No matter how! When you turn around, you will always rotate again! Then, it should always meet the studs on the car tires. After all, the studs will always appear in cold and humid areas. Tungsten carbide studs are mainly embedded in car tires to prevent the car from slipping on wet skating surfaces and have a very broad market in many European…

Since Trump announced on the 20th of this month that the United States will withdraw from the “Medium Guide Treaty” signed by Russia, foreign diplomatic agencies and the media have taken action to try to figure out what the real intention behind the “retrefation” of the United States is. Although Trump claims that the United States would want to withdraw from the landmark “middle-range nuclear power treaty” because of Russia’s long-standing violation of the treaty. In this regard, the Russian…
