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.
