Sintered Brass Filter

A sintered brass filter is a type of porous metal filter made from sintered brass particles. The sintering process involves compacting the brass particles at high temperatures without melting them, resulting in a solid piece with interconnected pores. These filters are used to separate solids from liquids or gases, allowing the fluid to pass through while trapping particles larger than the pore size.

Material of Sintered Brass Filter

The primary material used in sintered brass filters is brass, an alloy composed of copper and zinc. Typically, the copper content in brass is between 60% and 90%, and the zinc content is between 10% and 40%, which gives the filter excellent mechanical properties and corrosion resistance. The filter can be made with varying proportions of copper and zinc to achieve specific characteristics.

Types of Sintered Bronze Filter

  • Sintered Brass Discs: These are flat filters with different diameters and thicknesses, often used in applications where a precise filtration area is required.
  • Sintered Brass Cartridges: These filters are cylindrical in shape and are commonly used in various industrial processes and equipment.

Technical Specifications

  • Filtration Fineness: The filtration fineness is the size of particles that the filter can effectively trap. It is typically expressed in micrometers (μm) or microns (µm).
  • Porosity: The porosity of the filter refers to the ratio of void volume to the total volume and influences the flow rate and dirt holding capacity.
  • Permeability: Permeability is a measure of the ease with which fluids can pass through the filter.
  • Temperature and Pressure Tolerance: Sintered brass filters can withstand high temperatures and pressure depending on their specific design and thickness.

Features:

  • High mechanical strength and durability
  • Corrosion resistance
  • High-temperature resistance
  • Uniform pore size distribution
  • Good permeability
  • Easy to clean and maintain

Uses and Applications:

Sintered brass filters are utilized in various industries and applications, including but not limited to:

  • Hydraulic systems: As suction or return line filters to remove contaminants from hydraulic fluids.
  • Pneumatic systems: To trap particles and ensure clean air in pneumatic devices.
  • Chemical processing: For filtration of corrosive liquids and gases.
  • Water treatment: To remove impurities from water in residential, commercial, or industrial settings.
  • Food and beverage industry: To filter liquids, oils, or gases in food and beverage production processes.
