High temperature furnaces

Refractory metals such as tungsten, molybdenum, rhenium, tantalum, niobium are largely used in many industries and plants in high temperature furnace and thermocouple, mechanical processing:  in vacuum brazing, sintering technology, in heat treatment as well as in research and development.  Beijing Tungsten & Molybdenum Group co.,ltd made  it  possible for high performance materials are resistant to temperatures of up to 2.800℃ in vacuum or protective atmospheres, more advantages are used in high-temperature processing equipment ,such as: low vapor pressure, low thermal expansion ,low heat capacity ,remarkable high-temperature strength and creep resistance. Sunstone has research and developed tungsten，molybdenum alloys and other high performance alloy compared materials (such as, TZM, MLR, WVM, etc.)，alloy composite material Significantly increased the structural stability and creep resistance

1: High-temperature annealing& brazing

High-temperature annealing & brazing has strict requirements for the purity and cleanliness of the furnace, the uniformity of temperature, and the ability of realize speed-cooling is a must Because of the difference of the condition and the products to be processed, metallic hot-zones and charge carriers  made of tungsten &molybdenum are used, vacuum brazing for applications in aerospace, electronics ,medical technology for the out gassing clean  Recommended products:
Development, design and manufacture of hot zones for vacuum furnaces
Transform and upgrade hot zones for vacuum furnaces
Heating elements

2：Sintering

 In the sintering process field, both continuous and batch high-temperature furnaces are used, heating elements made of tungsten or molybdenum are generally used in continuous high-temperature furnaces, the temperature up to 1900℃with a variety of furnaces is used in high-temperature sintering processes, sintering boat, tray and chassis, are used by made of molybdenum ,usually, or it is best to use sunstone high performance  material lanthanum molybdenum alloy(MLR alloy)
Recommended products:
Molybdenum boat, molybdenum tray, TZM alloy
