Is there any difference between Tungsten Bar/Rod Slicing Disks and Tungsten Powder Sintering Disks?
The biggest difference between pure tungsten contact and sintered tungsten contact is:
1. Different density 2. Different grain size 3. Different hardness of tungsten sheet. 4. Different production process 5. Different life.

1-Tungsten content: ≥99.95%
2-Density: 19.2 g/cm3
3-Hardness: HV1≥460
4-Grain size: 12000 ps/mm2
5-Process: pure tungsten rod cutting
Tungsten Powder Sintering Disks:
1-Tungsten content: ≥99.95%
2-Density: 18.2g/cm3
3- Hardness: HV1≥325
4- Grain size: 11500 ps/mm2
5- Process: Tungsten powder pressing and sintering
What's the Pure Tungsten Contact and Application ?
Tungsten Rivet or tungsten contact can be made from tungsten rod or tungsten disk.Tungsten point/contacts are for use in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380℃ which gives it excellent arc-erosion resistance.Tungsten may develop troublesome oxide films, especially when used as the anode contact in some DC applications. Therefore, pure tungsten is often used as the cathode contact, and a palladium alloy used as the anode contact. Such a combination also minimizes contact interface resistance and material transfer.
