Metal sintered filter elements can be divided into three categories according to the material: stainless steel sintered filter element, copper powder sintered filter element, and titanium rod filter element.
1. Stainless steel sintered filter element
The stainless steel sintered filter element is a filter element made of stainless steel powder 304/304L/316/316L, which is formed by a mold and fired at high temperatures. High strength, suitable for high temperature and corrosive environments. Widely used in medicine, water treatment, food, biology, petroleum, chemical industry, metallurgical industry, and gas purification, dustproof and dustproof.

Performance index: accuracy range: 5-100um; temperature resistance: 400 ℃; easy to clean, regenerable, high strength, processable, weldable, uniform pores, can be used for material distribution, can be used normally and stably in various acid and alkali environments. Due to the advantages of one-time molding of powder, the shape and size can be customized according to requirements.
2. Copper powder sintered filter element
The copper powder sintered filter element is made of selected spherical tin bronze (tin-zinc-copper) powder, loaded into the processed mold, and formed by high-temperature firing. The particle size of copper powder is between 20-300 mesh, and the pore size of copper filter core formed by copper powder with different diameters is different, and the corresponding precision is 3-100 microns. The larger the mesh, the smaller the precision. Also because of the mold forming, the size and shape can be customized according to the requirements of different manufacturers.

Performance: With various porosity (28%-50%), pore size (4u-160u), and filtration precision (0.2um-100um), the pores are crisscrossed, high-temperature resistance, resistance to rapid cooling, and rapid heating. Corrosion resistance. Suitable for a variety of corrosive media such as acids and alkalis.
3. Titanium rod filter element
Titanium rod filter element is a kind of industrial high-purity titanium powder (99.6%, 0.4% is titanium alloy: nitrogen, hydrogen, iron, manganese, etc.) as raw material, after sieving and cold isostatic pressing. , Porous titanium filter elements sintered at high temperature and high vacuum.
