Application

About 50% of the tungsten ores mined in the world are used for smelting high-quality steel, about 35% for producing hard steel, about 10% for making tungsten wire and about 5% for other purposes. Tungsten can be used to manufacture guns, nozzles of rocket propellers, armor piercing bullets, metal cutting blades, drill bits, superhard molds, wire drawing molds, etc. tungsten is widely used in mining, metallurgy, machinery, construction, transportation, electronics, chemical industry, light industry, textile, military industry, aerospace, science and technology and various industrial fields.

Tungsten copper (or tungsten silver) alloy containing 60% - 90% tungsten is an excellent contact material, which can be used as electric key, knife switch, circuit breaker and spot welding electrode. Tungsten nickel copper alloy can be used as a and V-Ray protective screen. In rocket engines, the uncooled nozzle made of tungsten and tungsten impregnated copper (silver) can withstand 3127 ° C high temperature, high pressure and high thermal stress. High density tungsten alloy is an important material of armor piercing projectile. It is also used in bowling, javelin and other sports equipment.

It is used as emitting electrode and X-ray cathode target of luminescent materials in lighting and electronic industry. It can also be used as heating body of high temperature resistance furnace. The thermocouple composed of tungsten and tungsten rhenium (26%) alloy can measure the temperature from room temperature to 2835 * C. Tungsten selenide can be used as lubricant for self-lubricating bearings, and its lubrication temperature range is - 217-350 ° C. The pigments of tungsten compounds are durable. Pure tungsten can be used to make electric filament and cathode of roentgen tube.

Because tungsten metal is resistant to high temperature and does not deform, it is used to make high-speed steel. It is a high-speed cutting tool used in industry and an essential material in military. Sodium tungstate can be used as mordant for silk fabrics, fireproof agent for cotton fabrics, colorant for glass and pottery, etc; It can also be melted into cobalt chromium tungsten alloy and other metal alloys to make various alloy drill bits.

Precision bearings generally use tungsten beads

Tungsten beads are commonly used in hunting shotguns

Tungsten beads are generally used for fishing weights

Characteristics of tungsten beads

One is high density. The higher density of the cemented carbide ball allows it to have more weight in the same volume, thus maintaining better stability and penetration during flight.

The second is high hardness. The high hardness makes the cemented carbide ball can produce greater impact force when hitting the target and improve the killing effect, so it is suitable for use in military equipment.

Third, strong impact resistance. The cemented carbide ball is able to maintain the stability of its shape and size after high-speed impact and multiple uses, which is especially important for shotguns that require frequent firing.

Fourth, wear resistance. Tungsten beads can be used in water meters, because it has corrosion resistance and resistance to rust. In this way, the water meter can be used for a long time, and there is no need to change the water meter frequently

Fifth, corrosion resistance. Tungsten beads have corrosion resistance so that it can work in flowmeter components where corrosion resistance is required.

Sixth, high temperature stability. Tungsten beads can maintain its unique properties at high temperatures, at the temperature of 500 degrees Celsius to 1000 degrees Celsius, the hardness remains unchanged, with strong high temperature performance

Seven is small volume. The high density of cemented carbide makes the cemented carbide ball widely used in situations requiring small volume and high specific gravity.

Tennis rackets also use tungsten metal?

The counterweight of the tennis racket, this seemingly small accessory, actually has an important impact on the hitting effect of the player. So why choose tungsten alloy for tennis racket weight?

The tennis counterweight plays a crucial role, it is installed on the edge of the tennis racket, by adjusting the balance of the tennis racket, to optimize the performance of the player. Adjust the weight layout of the tennis racket according to personal characteristics.

Tungsten alloy with its excellent high density, high strength and high hardness properties, in many counterweight applications occupy a place, tennis racket counterweight is a typical representative of them. This counterweight uses metal tungsten as raw material, which ensures the non-toxicity and environmental protection of the product, and fully meets the international environmental protection requirements.

In addition, tungsten alloy counterweight also has the characteristics of easy processing, which provides designers with more space. They can design counterweights of different shapes and weights according to the needs and preferences of players to meet the individual needs of different players.

What are the military applications of tungsten metal?

We also know that steel barrels do not have a long service life. Therefore, in order to extend the service life of the gun barrel, that is, to enhance the resistance of the gun barrel to the corrosive effect of gunpowder combustion, people added tungsten to the gun steel as early as 1822.

By World War I, German ordnance engineers had paid special attention to tungsten barrels. According to data, at that time, the Russian and French light machine guns could only fire about 6,000 bullets before they were damaged, while the German light machine guns could fire 15,000 bullets, more than double. However, this still could not meet the needs of the war, especially for the lack of tungsten resources, but also in particular the need for tungsten to wage war Germany.

The Germans could not be said to have been without foresight, after all, they had stockpiled considerable quantities of tungsten ore before the war. However, the tungsten ore ran out shortly after the outbreak of war. Therefore, the military industry sector suffering from no source of "tungsten" has a high voice. Fortunately, at this time, German metallurgists remembered a big thing - tungsten can be found in the waste slag of tin smelting.

At that time, the tin refining industry in Germany could not but be said to be underdeveloped, so, tin waste residue, of course, is "everywhere." Therefore, the German military industry extracted tungsten from it as an emergency. A century later, the German ordnance industry is still well known. And tungsten steel has been used in all kinds of military equipment. In this regard, you can also see why tungsten can become one of the important strategic metals.

In addition, tungsten is the most widely used and highly consumed tool material, which can improve the production efficiency of the arms industry. How to improve the efficiency of tool steel? In 1864, an Englishman named Machette did it, and he first added 5% tungsten to tool steel to achieve a cutting speed of UP50%. This tungsten-containing tool steel is now often referred to as high-speed steel.
