High-Flow Sintered Bronze Filter from China Factory - Reliable Suppliers for Versatile Filtration Solutions
Parameters of Sintered Bronze Filter
1. Filtration precision: 0.5 micron to 120 micron, supporting nanoscale filtration needs (e.g., Manufacturer A's 0.5 micron grade products).
2. Porosity: 10%-50%, 15% increase in pore distribution uniformity, 10% increase in filtration efficiency.
3. Temperature resistance: conventional working temperature -40°C to 300°C, high temperature resistance up to 450°C (reduction environment) under special process.
4. Mechanical strength: compressive strength 100-300MPa, tensile strength 3-5 kg/mm², can withstand 20MPa high pressure.
5. Material composition: 89% copper + 11% tin, some products add nickel, chromium and other elements to enhance corrosion resistance.
Production Process of Sintered Bronze Filter
1. Raw material processing: choose spherical bronze powder (particle size 50-80μm), mix it evenly through ball mill.
2. Forming process: loose sintering (powder directly into the mold) or isostatic pressure molding, mold material for cast iron, graphite or alumina.
3. Sintering process: vacuum sintering or hot press sintering, temperature range 800-1070°C (depending on the powder composition adjustment), time 20-60 minutes.
4. Post-processing: fully automatic cleaning to remove impurities, chemical plating/electroplating surface enhancement (to improve abrasion resistance), strict quality inspection (porosity, compression test).
Advantages of Sintered Bronze Filter
1. High precision and efficient filtration: micron-level filtration precision, removes tiny particles (such as 5μm impurities) in oil and gas.
2. Resistant to extreme environment: resistant to strong acid, strong alkali, high temperature and high pressure, suitable for chemical industry, petroleum and other harsh working conditions.
3. Long life and easy maintenance: high permeability, can be repeatedly cleaned and regenerated, service life is 20% longer than the traditional cartridge.
4. Customized design: support non-standard size, shaped structure (such as with threaded cartridge), to meet the special needs of automotive, aviation and so on.
5. Intelligent management: integrated IoT sensors, real-time monitoring of filtration efficiency and early warning of malfunction (Manufacturer C technology).
