Tennry Applications
Graphite combines thermal stability, electrical conductivity, chemical resistance, lubricity and machinability. Tennry matches graphite grades and product designs with the operating conditions of different industries.
Solar PV and Semiconductor Manufacturing
Boasting heat/corrosion resistance and great conductivity, graphite is widely used throughout PV production from silicon smelting to cell manufacturing and thermal control.
Vacuum Furnace and Heat Treatment
Vacuum furnace accessories graphite heating tube, heat insulation screen, graphite, graphite, graphite plate, graphite material sets spare parts such as guide rail, graphite, graphite nut, get increasingly extensive application in the vacuum sintering furnace.
Foundry and Metal Casting
Artificial graphite excels in casting molds, thermal insulation and gating systems with outstanding high-temperature stability
Aluminum Degassing
Graphite products serve aluminum electrolysis & casting as anodes, cathodes, molds and rotors with outstanding thermal & conductive traits.
EDM Machining and Mold Manufacturing
Graphite EDM electrodes outperform copper with heat resistance, fast machining, light weight and recyclability for precision manufacturing.
Mechanical Seals and Pump Parts
Graphite excels in machinery for lubrication, high-temp parts, EDM, chemical gear, nuclear and lithium batteries via unique physicochemical traits.
Chemical and Petrochemical Processing
Graphite with superior heat, chemical & conductive properties is widely used in chemical & petrochemical reactors, heat exchangers, catalyst carriers, seals, lubricants and adsorbents.
Glass and Ceramic Manufacturing
Artificial graphite blocks serve glass molds and ceramic firing, boasting thermal shock & high-temp resistance, uniform heating to lift yield and cut production costs.
Passive Fire Protection
Unique stable graphite, especially expandable graphite, is widely used in fire doors, sealing strips, coatings and firestops to block fire and smoke.
