• Material:  Pure Aluminum(1060) or Aluminum alloy(3003、 5052 ect )
• Thickness: 0.01-0.05mm , requiring a balance between strength and weight (such as 0.08mm for lightning protection scenarios and 0.05mm for lightweight scenarios).
• Hole shape: diamond hole size usually,  and other round, rectangle, square, circle can be custom produced as well. 

–Square/rectangular holes: convenient for standardized production, suitable for filtering and protection (such as 1×1.5mm rectangular holes);
–Diamond shaped hole: with higher tensile strength, suitable for parts that need to bear loads (such as the support mesh under the wing skin);
–Circular hole: with low airflow resistance, suitable for aerodynamic optimization requirements (such as hole diameter 1-2mm, aperture ratio ≥ 70%).

• Strand width: generally 0.2-0.5mm, with an upper limit when the strength requirement is high (such as at the leading edge of the wing where the airflow impacts, stem width ≥ 0.3mm).
• Diamond hole size: 0.5x1mm 0.8×1.5mm 1x2mm 1.5x3mm 2x3mm…
• Density: Approximately 2.7 g/cm ³,
• Per sqm weight:  lightweight.  sqm weight range from 66g/sqm(2AL8-075F)   78g/sqm(4AL8-080)     137g/sqm(5AL10-080), and other types…

• Corrosion resistance: The surface is prone to forming a dense oxide film (Al ₂ O3), and has strong resistance to acid and alkali corrosion. 
• Thermal conductivity: The thermal conductivity coefficient is about 205 W/(m · K), and the electrical conductivity is excellent.
• Flexibility: Flexible and foldable, suitable for processing complex shapes.
• Opening rate=(mesh area/total area) × 100%, usually ≥ 50% is required to reduce weight; The filtering scenario can be appropriately reduced to 40% -60% to balance interception efficiency and ventilation volume.

(1) Lightning protection of aluminum foil mesh :  It is necessary to have high conductivity (pure aluminum or conductive alloys are preferred, such as 1060 aluminum with a conductivity of about 61% IACS), and the mesh structure should be continuous and uninterrupted to ensure rapid conduction of lightning current. The mesh density should not be too high (such as mesh edge length ≤ 5mm) to avoid the risk of lightning breakdown caused by excessive aperture; Multi layer stacking structure can be used to enhance conductivity.
(2) Aluminum foil mesh with light weight: Choose low-density materials (pure aluminum has a density of about 2.7g/cm ³, while aluminum alloys such as 5052 have similar densities), while optimizing the thickness of the mesh and stem width (such as plate thickness ≤ 0.1mm, stem width 0.2-0.3mm). On the premise of meeting the strength requirements, try to increase the mesh area as much as possible (such as hole size 1x2mm or more) and reduce the amount of material used.

(3) Protection and filtration (such as dust prevention for ventilation openings): The mesh size should be smaller than the particle size of foreign objects (such as ≤ 1mm), while ensuring ventilation efficiency (opening rate ≥ 60%); The material should be resistant to air flow erosion (surface hardness ≥ 60HV). Adopting diamond or rectangular holes (such as 1×1.5mm) to balance filtration accuracy and airflow permeability.
(4) Aerodynamic performance optimization (auxiliary function): The surface of the mesh should be smooth and flat (roughness Ra ≤ 1.6 μ m) to avoid protrusions or burrs that increase air resistance; The shape of the mesh should conform to the direction of the airflow (such as long strip-shaped holes arranged along the wing span)
