Product Description


Advantages:

1. Refractory.
2. Isostatic Pressed.
3. Long Service Life.
4. Superior Mechanical Strength.
5. High Corrosion and Wear Resistance.
6. Good Insulation Performance Precision.
7. High Temperature and Pressure Resistance.
8. High Purity Zirconia and Alumina Ceramic Material.

They are high corrosion and wear resistance and strong impact resistance and delivers 10 times longer working life than metal parts. They give a longer life to the sealed packing material.

Application:
Alumina ceramic is mainly used in large power equipment, IC MOS tube, IGBT chip heat conducting insulation, high frequency power supply, communication, mechanical equipment, strong current, high voltage, high temperature and other thermal heat insulation parts need products.
Physical properties: high thermal conductivity, high voltage insulation resistance, high temperature resistant, abrasion resistant, high strength.

Machining precision data: (reference data,the actual data is subject to the actual conditions)
(1)Shaft parts: Radial dimensions can reach 0.0015 mm; roundness 0.001 mm, concentricity 0.0025 mm, roughness 0.01
(2)Hole type parts:Machining minimum aperture of 0.3 mm, depth can reach 3 mm;The diameter of 1 mm can be radial 0.002 mm;Roughness 0.02-0.04;
(3)Plane processing:The tolerance can reach 0.002 mm, and the plane is 0.0015mm.
(4)Ceramic thread processing:the internal thread M2 can be grinds, thread precision GB-7h; The outer thread size is not limited, the precision GB-6g;
