Tungsten

A: Over the past few weeks, tungsten cubes (tungsten cubes) have become a craze in the cryptocurrency world, making it difficult for ordinary people to understand why a small cube can make cryptocurrency enthusiasts so obsessed. What is the magic power of it?
Cryptocurrency enthusiasts who hold tungsten cubes all have the same feeling, that is, they feel that this world is real, unlike Bitcoin, which is only presented in the form of numbers and cannot allow its holders to truly feel its existence, and Touch it.
It is said that most cryptocurrency traders who do not hold tungsten cubes now feel very panicked as if they have missed a big event. It is a FOMO phenomenon, that is, "Fear of Missing Out" (referred to as "Fear of Missing Out"). FOMO" refers specifically to the anxiety of always worrying about losing or missing out on something, also known as the "outsider's dilemma").
Torkel Rogstad, a software engineer at the digital financial platform Arcane Crypto, posted a related tweet on Twitter. He said: "It is very painful to wait for the arrival of tungsten blocks." This proves the FOMO of Tungsten Cube, or FOMO WC (FOMO of Tungsten Cube) among people who don’t have a physical object in hand.
Affected by the news that cryptocurrency enthusiasts are obsessed with tungsten cubes, cryptocurrency traders and even ordinary people who do not hold it have also placed orders to purchase on relevant platforms as soon as possible, prompting an increase in demand for tungsten cubes.
A tungsten cube is a cube containing refractory metal tungsten, such as pure tungsten block, tungsten-copper alloy block, tungsten-nickel-iron alloy block, and tungsten-silver alloy block, etc., usually used as a paperweight. Paperweights are things used to press down paper when writing and drawing. Paperweights made of tungsten products have smaller sizes, larger weights, wear resistance, corrosion resistance, oxidation resistance, high-temperature resistance, resistance to deformation and fading, etc. features, so it retain its original appearance no matter how many years it is used.
What is even more fortunate is that the tungsten alloy paperweight polished with diamond tools has a more exquisite appearance and better feel. At the same time, engraving or patterns can be carried out on its surface, so that it can be used as a gift or souvenir for friends.
In terms of production costs, the cost of tungsten cubes is not only related to the tungsten content and the amount of other auxiliary materials but also affected by its size. Normally, when the amount of raw materials is within a certain range, the larger the square, the higher the cost, because large squares are difficult to process and are extremely prone to sandwiching, cracks, deformation, or breakage.

A: Vacuum coating is a common surface treatment process used to form a thin film on the surface of a material to provide specific functionality or aesthetic effects. Tungsten boat plays an important role in the vacuum coating process. The following are the applications of tungsten boats in vacuum coating:
Carrier and material container: As a carrier and material container in the vacuum coating process, the tungsten boat can carry the materials to be processed while maintaining stability in high temperature and vacuum environments and is not prone to deformation or melting.
Material evaporation source: During the vacuum coating process, the target material needs to be heated above its melting point to evaporate and deposit on the surface of the object to be processed. The tungsten boat can be used as a heating source for materials. By heating the tungsten boat, the material at the evaporation source reaches the evaporation temperature.
Uniform evaporation: The shape and surface characteristics of the tungsten boat help achieve uniform evaporation of the material, thereby ensuring a uniform film deposition on the surface of the object to be treated.
High-temperature resistance: The tungsten boat has good high-temperature resistance and can withstand the high-temperature conditions required in the vacuum coating process. It is not easy to melt or deform, ensuring the stability and reliability of the coating process.
