Professional Supplier High Pressure Washer Ceramic Piston¹

Product Description Alumina ceramic piston / plunger Characters:1. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.2. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.Properties Units95 Alumina 99  Alumina ZrO2 Density g / cm33.653.95.95-6.05Water absorption %000Coefficient of thermal expansion 10-6/K7.98.510.5Modulus of Elasticity Young's Mod   GPa280340210Poisson's ratio /0.210.230.3HV Hardness  MPa140017001300-1365Flexural Strength @ room temperature MPa280320950Flexural Strength @700°CMPa220230210Compressive Strength @ room temperatureMPa200022002000Fracture Toughness  MPa *m 1/23.84.310Heat conductivity @ room temperature W/ m*k 18-2526-302-2.2Electrical Resistivity @ room temperatureΩ*mm2 /m10^1510^1610^15Max use temperature  °C185022001500Resistance to acid alkaline    /high high high Dielectric Constant /9.59.826Dielectric  Strength KV/mm101010Thermol Shock Resistance T ( °C )220190280-350Tensile Strength @ 25 °CMPa 200248260Thermal Conductivity(25oC)W/m·K30353 FAQQ: Are you trading company or manufacturer ?A: We are factory. Q: How long is your delivery time?A: Generally it is 5-10 days if the goods are in stock. or it is 15-30 days if the goods are not in stock, it is according to quantity. Q: Do you provide samples ? is it free or extra ?A: Yes, we could offer the sample for free charge but do not pay the cost of freight. Q: What is your terms of payment ?A: Payment<=1000USD, 100% in advance.
