Tungsten Cubic Uses and properties of molybdenum-copper

Molybdenum Copper military power suitable for the manufacture of microelectronic devices as a heat sink and tungsten cubic the sealing material of aluminum oxide ceramic sealing and structural materials molybdenum-copper alloy rod, but also for the manufacture of microelectronic devices civil power
Pieces of high thermal conductivity given inflation sealing heat sink with molybdenum copper alloy rod .
Molybdenum-copper alloy of copper and molybdenum comprehensive advantages of high strength, high specific gravity , high temperature resistance, arc ablation , electric conductivity properties, tungsten filaments good processing performance. Using high -quality oxygen-free copper molybdenum powder and powder , apply isostatic
Pressure molding ( high temperature sintering - copper infiltration ) , to ensure product purity and accuracy ratio, organized crime , and excellent performance. Breaking arc resistance, electrical conductivity, thermal conductivity, thermal expansion smaller.

tungsten bar Another important use of tungsten

Another important use of tungsten, which is in rockets, missiles, spacecraft, and return-type nuclear reactors and other important applications on the cutting-edge science. This is because the tungsten having excellent physical, mechanical, corrosion resistance and nuclear performance reasons. Such as tungsten alloy at 1900 ℃ high tungsten carbide ball tungsten carbide plate is still large, and in such high temperatures, either steel or heat-resistant super alloys are melted into a liquid. Mainly used to manufacture various types of rocket engines without cooling throat; made ​​with infiltration silver tungsten nozzle can withstand temperatures above 3100 ℃ for various types of missiles and aircraft; tungsten fiber composite materials produced by the rocket nozzle, the ability of 3500 ℃ or higher; in the chemical tungsten weights industry, equipment and components for corrosion do; do lubricants, pigments, and various reactions.

Tungsten Cubic Molybdenum deficiency disorders on the

Molybdenum deficiency disorders molybdenum disk on the human body: the body's energy metabolism can place obstacles, resulting in myocardial hypoxia and focal necrosis. Prone to kidney stones and urinary tract stones. Lead to iron deficiency anemia. Promote dental caries. And the incidence of esophageal cancer are closely related. Overdose: gout-like syndrome, joint pain and deformity, kidney damage. The body's requirement for molybdenum growth retardation, weight loss, hair loss, atherosclerosis, molybdenum foil connective tissue degeneration and skin diseases.

Molybdenum does to the human body

1. Maintain the myocardial energy metabolism: Kekai molybdenum chart is a composition of several kinds of enzyme in myocardial, play an important role in myocardial energy supplies. Keshan disease is a kind of cardiomyopathy, has proved that selenium deficiency is one of the causes, but more direct reason is the lack of molybdenum.

2. Molybdenum and immune: on the immune function of patients with keshan testing found that specific cellular immune function is reduced, molybdenum crucible deficiency crowd of supplements molybdenum immune function recovery. But too molybdenum also have damage to the immune function, and this has been confirmed in the animal experiments.

3. Adjust the thyroid gland secretion: research has shown that in keshan disease ward in the crowd and molybdenum and selenium, can adjust the thyroid function, thyroid function returned to normal.

Molybdenum deficiency may be one of the cause of esophageal cancer.

The Chinese nutrition society made the daily diet of molybdenum disk "safety and appropriate intake" reference indexes, infants less than 6 months each 0.03 ~ 0.06 mg per day, 1 year old of less than 0.04 ~ 0.08 mg per day, 1 over the age of 0.05 ~ 0.10 mg, 0.06 ~ 0.15 mg, aged 4 7 years old of above 0.10 ~ 0.30 mg per day, 11 years of age or older to adult is 0.15 ~ 0.50 mg per day per person. This index and the scientific research committee of food and nutrition council estimates of "safe and appropriate

Tungsten bar red pigment and pigment Fast precipitan Metal catalyst

used in the manufacture of alkaloids , ink , fertilizers , Kekai tungsten bar red pigment and pigment Fast precipitan Metal catalyst , molybdenum salts , can also be used to make flame tungsten boat and suppression of pollution- water system Pr

eparation , also used as galvanizing , polishing agents and chemical reagents.

The use of tungsten bar pellets

Tungsten alloy ball density, small size, small size, high specific gravity field components can be used as needed. Wolfram Alloy can be used as a golf ball counterweight , fishing sinkers , military counterweight , missile warheads, wear

A bomb warheads, Kekai Tungsten & Molybdenum technology tungsten alloy cartridges , prefabricated fragments ; also as a counterweight oil drilling platform And a number of other high- confidential areas, such as balancing the phone vibrator , pendulum clock and automatic watches to see, Shockproof holder, flywheel counterweight . These areas need to use tungsten carbide ball pellets .

Carbide - Tungsten Steel & Tungsten bar

Tungsten steel is carbide, also known as tungsten alloy. Hardness can reach 89 ~ 95HRA, reason, tungsten steel products (commonly tungsten carbide rods steel watches), with easy to be worn, not afraid of hard annealing, but brittle characteristics. 

The main components of carbide tungsten alloy carbide and cobalt, which accounted for 99% of all ingredients and 1% other metals, it is also known as copper tungsten. 

Commonly used in high-precision machining, precision cutting tool materials, lathes, impact drill bit, glass cutter head, above the tile cutter, hard afraid of annealing, but brittle. Are rare. 

Tungsten steel (alloy) with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at a temperature of 500 ℃ also remained unchanged, at 1000 ℃ still very high hardness. Carbide is widely used as a material, such as turning, milling, planer, drill, boring knife, for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut resistance material difficult to process hot steel, stainless steel, high manganese steel, tool steel. New carbide cutting speed is equal to the number of times the carbon steel. 

Tungsten steel (alloy) can be used to make drilling tools, mining tools, drilling tools, measuring tools, wear parts, metal grinding, cylinder liners, precision bearings, nozzles.
