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).

Frequently Asked Questions (FAQ)
What is the filtration precision of a sintered bronze filter?
The filtration precision of a sintered bronze filter typically ranges from 0.5 micron to 120 micron. This wide range makes it highly effective for both nanoscale and micro-level particle filtration requirements.
What temperatures can a sintered bronze filter withstand?
Under conventional working conditions, it operates safely between -40°C and 300°C. With special manufacturing processes, it can withstand high temperatures up to 450°C in reducing environments.
Can these filters handle high-pressure environments?
Yes. Sintered bronze filters have high mechanical strength with a compressive strength of 100-300MPa and can withstand operational pressures up to 20MPa, making them suitable for demanding aerospace and hydraulic applications.
What is the typical material composition of a sintered bronze filter?
They are primarily composed of 89% copper and 11% tin. Depending on specific application needs, elements like nickel and chromium are added to further enhance corrosion resistance.
Are sintered bronze filters cleanable and reusable?
Yes, one of the main advantages of sintered bronze filters is their high permeability and structural integrity, which allows them to be repeatedly cleaned and regenerated, extending their service life by 20% compared to traditional cartridges.
How is the porosity of the filter controlled during production?
Porosity, which ranges from 10% to 50%, is precisely controlled during the sintering process. Using spherical bronze powder with a particle size of 50-80μm and sintering at temperatures between 800-1070°C ensures a highly uniform pore distribution.
