Alumina ceramics are resistant to chemical corrosion and are not easily corroded by corrosive substances such as acids and alkalis. They are very suitable for applications that are often in a waste environment.
Alumina ceramic valve core can effectively prevent corrosion from various acids, alkalis, and salts. For example, it performs well in strong acid environments such as sulfuric acid (H₂SO₄), nitric acid (HNO₃), and hydrochloric acid (HCl), and will not be corroded by these acids; it has good tolerance to strong alkalis such as sodium hydroxide (NaOH) and potassium hydroxide (KOH) and will not be corroded; it also has good stability in salt solutions such as sodium chloride (NaCl) and potassium chloride (KCl) and will not react chemically. Therefore, our products have natural advantages in various sewage environments.
Ceramic Valve Core is commonly used in faucet valve cores, industrial valves, etc. It is a very core component with adjustment and control functions.
The alumina ceramic valve core has a smooth surface and excellent sealing performance, which can effectively prevent leakage and other problems.

*The table above only shows typical properties of common alumina materials. The properties of custom alumina parts will vary depending on the purity and process selected. We can provide custom alumina filter/valve services based on your specifications.
The use of alumina filter element/valve element
- Water treatment: used in industrial or domestic water treatment systems;
- High temperature filtration: suitable for gas or liquid filtration in high temperature environments;
- Chemical filtration: The corrosion-resistant characteristics allow the ceramic filter element to work in environments with serious industrial pollution;
- Food and Beverage Processing: Alumina ceramics are non-toxic and can be used to filter drinking water, juice, and more;
- Faucet valve: The wear-resistant and corrosion-resistant characteristics of the alumina ceramic valve core can ensure that the faucet will be used without dripping for a long time;
- Industrial valves: used as industrial valves in the chemical, petroleum, pharmaceutical and other aviation industries. Alumina ceramics are resistant to high temperatures and corrosion, and have good reliability;
- Household appliances: water inlet valves and outlet valves for washing machines, dishwashers and other household appliances;
