Industry-Specific Applications

1. Aerospace & Defense

• Engine Air Filters: Gr5 mesh withstands 500°C exhaust gases (MIL-DTL-5541 compliant).
• EMI Shielding: Gr1 woven shields (40–100 mesh) block 99% RF interference up to 40 GHz.

2. Medical & Biomedical

• Surgical Implants: Gr2/GR7 meshes (ISO 5832-2 certified) for bone reconstruction.
• Dialysis Filters: 200-mesh Gr1 with 0.1 μm precision pores (FDA 510(k) cleared).

3. Marine & Desalination

• Reverse Osmosis Screens: Gr7 resists pitting in 70,000 ppm brine (ASTM G61 tested).
• Shipbuilding: Gr9 mesh for lightweight hull reinforcement (DNV-GL approved).

4. Chemical Processing

• Chlorine Gas Filters: Gr7’s Pd content prevents stress corrosion cracking (NACE MR0175).
• Acid Recovery: Gr2 mesh in 98% H2SO4 at 80°C (0.05 mm/yr corrosion rate).

FAQ Section

Q1: Is titanium mesh MRI-compatible?
A: Yes – Gr1/Gr2 are non-ferromagnetic (ASTM F2213 tested).

Q2: How does Gr7 resist chlorides?
A: Pd additives form stable oxides, reducing crevice corrosion risk in Cl⁻ >10,000 ppm.

Q3: Minimum bending radius?
A: 2× wire diameter for Gr1/Gr2; 4× for Gr5 (prevents alpha-case embrittlement).

Q4: Cost comparison to stainless steel?
A: Initial cost 5–8× higher, but lifespan 10× longer in corrosive environments.
