Applications Of Tungsten Bars
1) For production of filaments for lamps of coiled-coil or three-coiled incandescent
Lamp, fluorescent lamp, halogen lamp, auto lamp and hi-color temperature lamps,
etc.
2) For making supports and electron tubes
Featrues Of Tungsten Bars
1) Size: Dia1.0mm Min*L2000mm Max.
2) Material: Pure tungsten and tungsten alloy
3) Property: Good winding property, non-sag, high temperature resistance
Polished/ground Tungsten Bars:
Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.

VICARB plate heat exchangers came from France and were later acquired by ALFA LAVAL. The rapid development of China's plate heat exchanger industry comes from VICARB technology.
The former Siping Heat exchanger General plant introduced French Vicarb heat exchanger technology. The sealing gasket of plate heat exchanger can be provided by EPDM, NBR, HNBR, VITON, FPM and so on.
Vicarb heat exchangers are suitable for a variety of heating, cooling, vaporization or condensation processes in a variety of media, such as air, liquid and steam, and can be widely used in precision instruments, food and beverage manufacturing, oil and energy industry and other fields.
As the world's leading plate heat exchanger plate manufacturer and seller, Baode has a wide variety of domestic plate heat exchanger plates, more models! It can provide all common types of plate heat exchanger plates from well-known brands at home and abroad (including: AlfaLaval /GEA, TRANTER, SONDEX/HISAKA/APV/Thermowave /Schmidt/FUNKE/VICARB/LHE, etc.).
