Al2O3 Ceramic Piston




Part name: alumina ceramic plunger/alumina ceramic piston

Specifications: φ18mm*φ10mm*L48mm

Material: alumina ceramic

Alumina oxide material is used in a great number of industries for many years because its excellent combination of good properties like mechanical strength, Vickers hardness, compressive strength, fracture toughness. Ceramic parts are usually made from 95% alumina, 96% alumina, 99% alumina, or even higher percent like 99.5%.


Al2O3, a non-metallic material, has many better properties than conventional materials, which resulting from its well-formed crystal structure.

Excellent electrical insulator at high temperatures

Good dimensional stability

High mechanical strength

Good abrasion resistance

Non-porous and vacuum tight

Corrosion resistant




The alumina ceramic plunger or piston is widely applied in agricultural pumps where there are high speed and high pressure, as well as high temperature caused by high speed of piston movement. Ceramic piston or plunger is capable of endure all these conditions. In addition, fluids flowing through agricultural pumps don’t have impact on the ceramic piston or plunger. These great properties obviously lengthen the service life of agricultural pumps
