The CuSn Sintered Powder Filter Element 14.1×27.5 is a high-performance porous metal filter element manufactured from tin bronze (copper-tin) alloy powder through a high-temperature vacuum sintering process.
CuSn bronze is the preferred material for small sintered metal filters, typically comprising 89–91% copper and 9–11% tin. The spherical tin bronze powder is sintered at 800°C–950°C through a loose-packed sintering process, creating a three-dimensional interconnected pore structure without the use of any binders or adhesives.

This sintered filter is manufactured by Huahang Filter, leveraging expertise in powder sintering technology and metallurgy. We focus on producing reliable, application-specific metal filters. Our controlled sintering process ensures consistent pore structure and performance in every batch. We provide technical support for material selection and can offer custom versions of this platform element with different end fittings, lengths, or surface treatments to meet unique system integration needs.
Controlled Sintering for Consistent Porosity: Our sintering process is finely tuned to create a uniform porous matrix, providing a reliable and predictable absolute filtration rating (e.g., 2, 5, 10, 20, 40 microns) in this small form factor.
Precision Thread Machining: The G¾ threads are machined to exacting standards, ensuring a perfect seal with standard fittings and preventing cross-threading or leakage in critical fluid paths.
High Material Purity & Integrity: We use high-grade 304 or 316L stainless steel powder, resulting in a filter with excellent corrosion resistance and structural integrity suitable for demanding analytical or process applications.
Durability and Cleanability: Despite its small size, the monolithic sintered structure is robust and can be backflushed or ultrasonically cleaned numerous times, offering long-term service life and value.

Q1: What is the composition of CuSn bronze used in this filter?
A: The filter is manufactured from tin bronze alloy (CuSn) , typically comprising 89–91% copper and 9–11% tin. This composition provides an optimal balance of strength, corrosion resistance, and cost-effectiveness.
Q2: How does CuSn bronze compare to stainless steel for filter elements?
A: CuSn bronze offers good corrosion resistance and excellent permeability at a lower cost than stainless steel. Stainless steel provides superior corrosion resistance in highly aggressive chemical environments and higher temperature tolerance. For general industrial applications (pneumatic, hydraulic, compressed air), CuSn bronze is often the more cost-effective choice.
Q3: What end connection types are available for this sintered filter element?
A: We offer multiple connection options to fit most filter housings:
Q4: Can the dimensions and filtration specifications be customized?
A: Yes. CuSn sintered powder filter elements can be manufactured in various shapes and sizes — including cylindrical, disc, cap, and custom configurations. We offer full customization services for dimensions, filtration accuracy, and connection types. Please provide your specific requirements for a custom quotation.
