Porous metal sintered bronze filter sheets are specialized filtering components manufactured through a sintering process using bronze powder or bronze alloy powder. These filter sheets contain numerous tiny pores that allow the passage of liquid or gas while capturing and filtering solid particles, impurities, or other contaminants within them.

The production process typically involves the following steps:

Processing steps

Raw Material Preparation

High-quality bronze powder or alloy powder is selected as the raw material. The particle size and composition of these powders are usually determined based on the requirements of the final product.

Mixing and Compacting

Bronze powder is uniformly mixed with potential additives to enhance its flowability and compressibility. The mixture is then placed into molds and mechanically compacted using high-pressure machinery to form preliminary sheet-shaped or disc-shaped products.

Sintering

The products, after compaction, undergo sintering under high-temperature conditions. During this process, diffusion welding occurs between the bronze powder particles, forming robust metal bonding points while creating porosity, which determines the final pore structure and pore size.

Machining and Shaping

Post-sintering, the products may require further machining and shaping, such as trimming edges or polishing surfaces, to ensure.

FAQ

01.What's the size of the filter sheet?

The porous metal sintered bronze filter is formed by using spherical bronze powder placed into preprocessed molds and then shaped through high-temperature sintering. The particle size of the bronze powder ranges from 20 to 300 mesh, and different diameters of bronze powder result in varying pore sizes within the bronze filter, with corresponding accuracy between 3 to 100 micrometers. A higher mesh count signifies smaller pores.

Furthermore, due to the nature of mold shaping, the dimensions and shapes can be customized according to the specific requirements of different manufacturers.

02.What are the advantages of sintering over bonding?

Sintering is not adhesion. Sintering primarily controls the material's melting point. Sintered filter cores have good strength, can be machined, riveted, and cleaned by backwashing. Additionally, they withstand high operating temperatures and belong to filter components.

03.What are the advantages of sintered bronze filter sheet?

These components are made from bronze alloy powder through high-temperature sintering, resulting in uniformly stable pores. They offer high filtration precision, providing good purification effects with minimal pressure loss. Additionally, they possess noise reduction and sound absorption capabilities.

04.What are the applications of sintered bronze filter sheet?

The applications include filtering gases, liquids, and fuel oil. They are widely used in industries such as petroleum, chemical, automotive, tractor, aircraft, and marine. Additionally, they find extensive use in filtering components within pneumatic and hydraulic circuits.
