One of the key reasons why rhenium is so important today is that rhenium has a rather unique property. Rhenium has no known ductile to brittle transition temperature unlike molybdenum and tungsten even after complete recrystallization annealing. Products from rhenium can be thermally cycled thousands of times with no ill effect. It can be alloyed with tungsten or molybdenum and, near the solubility limits, imparts improved ductility to those materials. High-temperature strength, low friction, ductility and other rather unique properties make it the material of choice for many critical applications.

    Most rhenium today is produced as a by-product of the copper & molybdenum mining industry. In China,it is also found in uranium . Usually,it's found in those copper ores contaminated with molybdenum. When they purify the copper the rhenium is extracted with the molybdenum in the form of sulfurous sludge. The high temperature roasting of the sludge to form molybdenum oxide releases the rhenium and it is collected and concentrated in special units. The next step is to make a medium purity ammonium salt containing rhenium called ammonium perrhenate (APR). This APR is sold around the world to various metal traders and catalyst manufacturers .

    In China,We refine it to high purity at our facility and produce a variety of powders, chemicals and fabricated materials and supply various customers all over the world.
