Product: Tap Cartridge Installation: Push Fit Material: Alumina Ceramic KEROX cartridge K-35B is suitable with but not limited to faucets from: - Cascade - La Torre - Kohler Al2O3 Ceramic Disc Cartridge Al2O3 is the chemical formula for aluminum oxide, a compound of aluminum and oxygen. Sintered by heat into ceramic, cartridges made from the material are considered durable with a compressive strength of at least 2,000 megapascals (MPa) and are said to have almost the same toughness as a diamond with a hardness of up to 19 gigapascals (GPa). It is less prone to corrosion and can last longer than cartridges made from other material. Another characteristic of alumina ceramic is its ability to slide, which is practical for a ceramic disc faucet. Two discs are used in such a faucet mechanism. The upper disc moves as the faucet is turned on and off while the lower disc remains static. The discs slide to align or misalign, which acts as a gateway to open or impede the flow of water.
