Cryptocurrency enthusiasts who hold tungsten blocks have the same feeling, that is, they feel that the world is real, unlike Bitcoin, which is only presented in the form of digital, unable to let its holders truly feel its existence and touch it.

 

The so-called majority of cryptocurrency traders who do not hold tungsten blocks now feel very panicked, as if Missing a big event, is actually a phenomenon of FOMO, that is, Fear of Missing Out (" Fear of missing out ", referred to as "FOMO"), which refers to the kind of anxiety that is always worried about losing or missing something. Also known as the "outsider's dilemma")

 

Under the influence of the news that cryptocurrency enthusiasts are obsessed with tungsten squares, cryptocurrency traders and even ordinary people who do not hold it also place orders to buy on the relevant platforms as soon as possible, prompting the demand for tungsten cubes to increase.

 

The tungsten cube is actually a kind of block containing refractory metal tungsten, such as pure tungsten block, tungsten copper block, tungsten nickel-iron block and tungsten silver alloy block, usually used as a paperweight. Paperweights are used to press paper when writing and drawing, and the paperweights made of tungsten products have smaller volume, larger weight, wear resistance, corrosion resistance, oxidation resistance, high temperature resistance, not easy to deform and fade, so no matter how many years of use, it can maintain the original appearance.

 

What is more fortunate is that the tungsten alloy paperweight polished by diamond tools has a more exquisite appearance and better feel, and it can be engraved or patterns on its surface, so that it can be used as a gift or souvenir for friends. A little more delicate, that is, it can be gold-plated on the surface of tungsten alloy paperweight, and the gold-plated product has a gold-like color, which can improve its collection value and appreciation value.

 

In terms of production costs, the cost of tungsten blocks 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 size of the box, the higher the cost, because the large size of the box is difficult to process, and it is extremely easy to appear sandwich, crack, deformation or fracture.

 

1,Tungsten cube is widely used for Ornament, decoration, gift, Balance weight, collection, target, Military industry, and so on;,

2,Birthdays, special days, anniversaries, it can be as a gift for your colleagues, wife, husband, friends, they will be Surprise with the cube's weight,small volume and large weight.

3,Pure tugnsten or tugnsten alloy cube 1kg also can be for your desktop or coffee table.

 

The most widely used tungsten products are carbide products known as industrial teeth. In addition, tungsten and its alloys are widely used in military, aerospace, IT communications, nuclear energy construction, medical equipment, sports fields such as darts fishing, rings and other crafts, and its use is still being studied and discovered.

According to the different size, tungsten cube can be divided into large, medium and small three kinds of squares;

 

According to the different materials, it can be divided into pure tungsten blocks (metal tungsten blocks), tungsten-based alloy blocks and cemented carbide blocks.

 

According to the different types and quantities of binder, tungsten-based alloy blocks can be divided into two-phase blocks (such as tungsten copper alloy blocks and tungsten silver alloy blocks), three-phase blocks (such as tungsten nickel-iron alloy blocks and tungsten nickel-copper alloy blocks) and high-entropy alloy blocks (multi-principal element alloys);

 

According to the different binder, the cemented carbide block can be divided into WC-Co alloy block and WC-Ni alloy block.

 

1. Pure tungsten block

 

Its purity is very high, can reach 99.999%, but it is also a refractory metal, hardness is also very high. It's not an easy thing to produce. Tungsten is easy to break, which will affect the appearance.More difficult is that the shape of the metal tungsten block and various processing due to its brittleness difficulty increase, so often require a high cost of slow wire to be better completed.

 

2, tungsten alloy square

 

1) two-phase gold nugget

Tungsten-copper alloy block: a two-phase structure pseudoalloy with tungsten as the hard phase and copper as the bonding phase, which has the advantages of high density, high melting point and good electrical and thermal conductivity. However, its oxidation resistance is poor, so it will rust in the natural environment, thereby reducing the overall quality. In addition, the color and density of tungsten copper products manufactured by copper infiltration method will also appear uneven, because copper (melting point 1083.4 ° C) and tungsten melting point is larger, when the temperature is higher, copper will melt into a liquid, resulting in high-density metal tungsten sinking at the bottom.

 

Tungsten silver alloy block: is composed of tungsten and silver blocks, although it has excellent plasticity, oxidation resistance and electrical and thermal conductivity characteristics, but the strength and hardness are relatively low, the price is high, so Xiaobian do not recommend collecting it. In addition to the silver price and silver content, the production cost depends to a large extent on the cost of production and processing. According to Chinatungsten Wisdom Manufacturing, the production method of tungsten silver block is the same as that of tungsten copper block. The melting point of silver is 962 ° C, and when the temperature is higher, it will also melt into a liquid, causing the metal tungsten to sink, resulting in uneven color and density of the block.

 

2) three-phase gold nugget

 

Tungsten-nickel-iron alloy block: is a tungsten based and add nickel and iron and other chemical elements of the alloy, with high strength, good wear resistance, strong anti-radiation ability, not easy to deformation and certain ferromagnetic characteristics, suitable for the traditional powder metallurgy process and injection molding technology to produce. Note: The nickel-iron ratio of commonly used alloys is generally 7:3 or 1:1.

 

Tungsten-nickel-copper alloy block: is a tungsten based and added to nickel and copper and other chemical elements of the alloy, with non-magnetic, high specific gravity, low thermal expansion coefficient, good electrical and thermal conductivity, processability and weldable characteristics, can be produced by powder metallurgy process. Note: the nickel-copper ratio of commonly used alloys is generally 3:2; Compared with tungsten nickel iron block, tungsten nickel copper block is more suitable for application in the field of magnetic sensitivity.

 

3) Tungsten high entropy alloy block

 

It is composed of five or more main elements such as tungsten, molybdenum, titanium and so on with the quantity ratio of such substances or the quantity ratio of nearly such substances, and each element accounts for 5%-35% of the total composition of the alloy, is a new material, in the phase structure stability, strength and toughness, corrosion resistance and radiation resistance and other aspects of the traditional alloy has unparalleled performance advantages, suitable for vacuum arc melting method to prepare.

 

3. Cemented carbide cube

1) WC-Co alloy block: is based on tungsten carbide, cobalt as a binder, a material manufactured by powder metallurgy, with high bending strength, good thermal conductivity, impact resistance and cutting resistance. However, due to the scarcity and high price of cobalt resources, the cost of blocks is relatively high.

 

2) WC-Ni alloy block: Tungsten carbide as the hard phase, nickel as the bonding phase of the alloy, with high hardness and good corrosion resistance and other characteristics, widely used in the field of mechanical equipment. However, it is precisely because of the high hardness of the alloy that it is very difficult to process and the production cost is large.

 

In addition, there are tungsten gold bars. Tungsten gold block refers to the ordinary tungsten block gold-plated a product, in addition to having the same physical and chemical properties as ordinary tungsten block, there is a high collection value and appreciation value. Its production cost is closely related to gold price and coating thickness.

 

In summary, compared with other tungsten cubes, tungsten nickel-iron alloy cubes have higher cost performance and are more suitable for collection. In the case of the same conditions of raw materials, raw material ratio, production process and process parameters, the physical and chemical properties of large, medium and small squares are exactly the same, so consumers should choose tungsten cubes according to their preferences or applications.
