Key words : Ceramic Washer / Spacer
In stock fully dense Alumina Oxide and Zirconia Oxide ceramic washers / spacer is the most widely used advanced ceramic material. It offers very good performance in terms of wear resistance, corrosion resistance and strength at a reasonable price. Its high dielectric properties are beneficial in electronic products.
Both the Alumina Oxide washers and Zirconia Oxide washers have matching ceramic screws and ceramic nuts.
If a special shaped or size ceramic washers is required, please advise and we will be happy to quote in both small quantities and large quantities.
High-quality ceramic washer / spacer (aluminum oxide Al2O3 99.9%, 99.7% and 96% and zirconia ZrO2)
Mingrui manufactures high qualityCeramic Washer / Spacer, made out of High Purity Alumina (96%, 99,7% or 99,9%) and TZP Zirconia ceramics for high and low pressure injection and selection valves. Rotors and Stators are subject to intensive mechanical stress and chemical aggression while having to maintain a perfectly leak free adjustment between the two components. No leak, limited stiction and low wear are the most important parameters to guarantee long life and reliability to your valve. These can be achieved by an adequate surface finish, a perfect flatness of the surfaces in contact and a proper selection of the material. Every application is different and Ceramaret will help you define the parameters required for your particular valve. Ceramic Washer / Spacer are used in valves for many high-tech applications, such as HPLC, micro-HPLC, Medical, Industrial, etc.
Typical Characteristics Ceramic Washer / Spacer: Outside diameter: < 30,00 mm ( 1.18") Thickness: < 7,00 mm ( . 28") Groove(s) dimensions: Width > 0,051 mm ( .0002") Depth > 0,13 mm ( .0052") Length > 2,00 mm ( .0780") Stator: Outside diameter: < 30,00 mm ( 1.18") Thickness: < 7,00 mm ( . 28") Hole diameter: > 0,22 mm x 0,25 mm (.008" x .010") Surface finish, Ceramic Washer / Spacer Zirconia: 0,025 m (1 in) or N1 Alumina 99,9 %: 0,05 m (2 in) or N2 Alumina 96% or 99,7%: 0,1 to 0,2 m (4 to 8 in) or N3 to N4
Advantages of Ceramic Washer / Spacer:
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. 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 plunger. They give a longer life to the sealed packing material.
