Product description
Polished tungsten rods for sapphire growing furnace:
- 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
Specification:
- Surface: black and polished
- Purity: 99.95%(min)
- Density: 19.3g/cm3
- Dia: 2.5-60mm
- Standard: ASTM
Surface condition:
- Black: Surface is black,retaining a coating of processing lubricants and oxides
- Bright: Surface is chemically cleaned to remove all lubricants and oxides
- Ground: Surface is centerless ground to remove all coating and to achieve precise diameter
Applications:
- For producing electric light source parts and electric vacuum components
- For producing heating elements and refractory parts in high temperature furnaces
- We can manufacture according to your requests.
