Alloyed with tungsten in 3%, 5%,25%, 26% content, rhenium make tungsten become more ductile and machineable.

ABOUT PLANTRefractory metal and ceramics planthas been developing from Refractory Alloy Research Department of CISR(Central Iron & Steel Research Institute) founded in 1958. As one ofthe earliest unit engaged in refractory metal research and production inChina,over the past 50years, more than 250 research projects have beendone and 58 great achievements have been made including 9 nationalinventions,40 metallurgy ministry awards and 21 national patents. Nowwe are at the top-level in refractory metal and ceramic materialresearching and producing within more than 300 sets of advancedproduction equipments and 20 sets of testing facilities.

AT&M Refractory Plant is ISO9001:2000 certified.

ANNUAL CAPACITY

The annual production capacity is more than 600 tons of tungsten and molybdenum products.

ABOUT PRODUCTAT&M has about 50 years of experience in researching and developing in Rhenium, Tungsten Rhenium and Molybdenum Rhenium Alloy, which are widely used in heating elements,temperature thermal couple, cathode of valve and other high temperature using parts.

 

Rhenium has several unique properties as follows

High melting temperature

Extreme resistance to chemical erosion

Ability to maintain ductility after recrystallization

High electrical resistivity over a wide temperature range

Low vapor pressure

Resistance to oxidation at very high temperature

Good thermal shock resistance

 

Alloyed with tungsten in 3%, 5%,25%, 26% content, rhenium make tungsten become more ductile and machineable.With good electrical properties, W-Re alloys are be used as high temperature thermocouple materials.

 

Molybdenum Rhenium Alloy with 41% or 47.5% of Rhenium (nominal content of Rhenium 50%) has good ductility, weld ability, formability and strength. MoRe alloy keep high ductile even after used in high temperatures. MoRe alloys are widely used for electronics, nuclear and space applications.
