Metal Sintered Mesh

Metal Sintered Mesh is engineered using advanced powder metallurgy technology, where metal powders (e.g., stainless steel, bronze, nickel) are compacted into a porous structure and sintered at high temperatures to form a durable, uniform mesh. Unlike woven or welded meshes, this process creates a ​​monolithic, interconnected pore network​​ with precise control over pore size, porosity, and mechanical properties. Ideal for high-performance filtration, heat transfer, and separation applications, sintered metal mesh combines the strength of solid metal with the functionality of porous media—making it a preferred choice for industrial buyers seeking reliability in extreme environments.

​​Technical Specifications​​

• ​​Pore Size​​: 1–1000 μm (standard tolerance ±10%; tight tolerance ±5% on request).
• ​​Porosity​​: 30%–60% (standard; up to 70% with reduced strength trade-off).
• ​​Thickness​​: 0.5–10 mm (standard stock sizes; custom thicknesses up to 20 mm available).
• ​​Materials​​:
  • ​​Stainless Steel​​: AISI 304/304L (general corrosion resistance), 316/316L (high corrosion/salt spray resistance), 904L (ultra-corrosion resistance for marine/chemical environments).
  • ​​Bronze (CuSn)​​: Excellent thermal conductivity (ideal for heat exchangers, brake systems).
  • ​​High-Temp Alloys​​: Nickel (Ni), Monel (NiCu, chemical/acid resistance), Inconel (1100°C continuous operating temp).
  • ​​Custom Alloys​​: Inconel, Hastelloy (C-276/C-22) available upon request for specialized applications.
• ​​Operating Temperature​​: Up to 1100°C (Inconel); 800°C (316L stainless steel); 600°C (bronze) (continuous use).
• ​​Standard Sizes​​: Rolls (widths: 100–2000 mm), sheets (min 100×100 mm – max 2000×4000 mm), or custom shapes (OEM prototyping supported).
• ​​Certifications​​: ISO 9001 (quality), ISO 14001 (environmental), PED 2014/68/EU (pressure equipment), FDA/USP Class VI (pharma/food-grade materials).

​​Key Features​​

• ​​Monolithic Structure​​: No delamination risk vs. laminated designs—resists deformation, tearing, or collapse under high pressure (tested to >300 bar in hydraulic systems).
• ​​Precision Pores​​: Laser-scanned for uniformity (ISO 4006 compliant), ensuring consistent separation of particles, liquids, or gases (critical for pharmaceuticals, semiconductors, and food processing).
• ​​Thermal Shock Resistance​​: Low thermal expansion coefficient minimizes stress cracking during rapid temperature cycling (CTE <12×10⁻⁶/K for 316L stainless steel).
• ​​High-Temperature Performance​​: Withstands extreme thermal conditions without degradation (e.g., Inconel retains strength at 1100°C).
• ​​Corrosion & Chemical Resistance​​: Stainless steel, nickel, and bronze alloys resist oxidation, acids, and solvents (suitable for harsh industrial environments).
• ​​Reusability​​: Easily cleaned via backflushing, chemical cleaning, or ultrasonics—extends service life to 100+ cycles.
• ​​Heat Transfer Efficiency​​: 30% higher than finned tubes (per ASME PTC 12.5), ideal for heat exchangers.
   

​​Primary Applications​​

Sintered Metal Mesh’s versatility makes it indispensable across industries requiring reliable, high-performance separation or heat management:

1. ​​Industrial Filtration Systems​​

   • Replaces fragile ceramic filters in high-pressure hydraulic systems (>300 bar) and chemical processing (removes particulates, sludge, or contaminants).
   • Membrane supports for ceramic/polymeric membranes in water treatment (enhances flow uniformity).

2. ​​Heat Exchangers & Thermal Management​​

   • As cores or fins in heat exchangers to enhance heat transfer while preventing clogging (30% higher efficiency vs. finned tubes).
   • Radiant burner nozzles in industrial boilers for uniform flame distribution.

3. ​​Catalyst Carriers​​

   • Supports for catalysts in chemical reactors (e.g., petroleum refining, exhaust gas treatment)—40% higher catalyst loading vs. honeycomb substrates.

4. ​​Dust & Fume Collection​​

   • Filters in HVAC systems, industrial vents, or welding fume extractors to capture fine particulates (down to 1μm).

5. ​​Food & Pharmaceutical Processing​​

   • Sterile filtration (e.g., beverage clarification, pharmaceutical solution sterilization) with FDA/USP Class VI-certified materials (meets leachables testing per USP <661>).

6. ​​Aerospace & Defense​​

   • Lightweight, high-strength components for aircraft engines, fuel systems, or protective armor.

7. ​​EV Battery Cooling​​

   • Custom-shaped 3D sintered heat spreaders for thermal management in electric vehicle batteries.
