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 bars, rods, profiles and profiles plates, sheets, strip and foil of a deeper level of processing products export tariffs, so the 5% export tax rebate policy will continue. It can be understood, at least for now, for this type of tungsten production and exports, the country is still allowed, and even encouraged.

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.
