Corrosion resistant porous metal bronze powder sintered tube filter uses bronze alloy powder (copper + tin as the main components) to form a porous structure through high-temperature sintering, which combines the mechanical strength of metal materials with the permeability of porous media. Its core advantages are high temperature resistance, corrosion resistance, high filtration accuracy and long life. Porous metal bronze powder sintered filter is widely used in gas/liquid precision filtration in industrial fields such as petrochemicals, water treatment, food and beverages, and pharmaceuticals.
Technical Data: • Porosity: 18-46% (adjustable) • Filtering precision: 0.5-200μm (surface filtration + depth filtration) • Compressive strength: ≥5 MPa (static) • Working temperature: -20℃~400℃ (excellent oxidation resistance) • Air permeability: 20-170 m³/(m²·h·kPa) • Dimensions: Support customization (round, square, special-shaped filter elements) • Material: Bronze alloy powder (Cu 85-90% + Sn 5-10%), corrosion-resistant elements such as nickel and chromium
Filter Material: We are a high-precision porous metal bronze powder tube sintered filter manufacturer that strictly follows technical specifications and standards to ensure product quality. The diameter, length and other dimensions can be customized according to actual needs. • Powder mixing: bronze powder and pore-forming agent are mixed in proportion to ensure uniform particle size distribution (1-150μm). • Forming process: isostatic pressing or rolling molding to control density and porosity. • Sintering process: sintering under vacuum or inert atmosphere (such as nitrogen) to form a dense skeleton structure. 
Application areas: ✅ Crude oil desulfurization ✅ Gas purification in catalytic cracking units ✅ Seawater desalination pretreatment ✅ Industrial wastewater reuse ✅ Aseptic filtration before beverage filling ✅ Cooking oil impurity removal ✅ Terminal filtration of water for injection ✅ Bioreactor gas sterilization
FAQ: Q: Does it support non-standard customization? A: The filtration accuracy, interface size and shell material can be customized.
Q: porous metal bronze powder sintered filter replacement cycle? A: Under normal working conditions, it is recommended to be 12-36 months, which actually depends on the degree of medium contamination.
Q: What is the shelf life of the porous metal bronze powder sintered filter? A: Usually 3 years, but the storage conditions will affect the actual service life. It should be stored in a dry and dark environment.
