Nickel titanium alloy filter screen is woven/pressed with nickel titanium memory alloy wire, and has shape memory, super elasticity, corrosion resistance, fatigue resistance, and biocompatibility. It is a high-end special filter material with a much higher price than stainless steel filter screen.

✨ Core Features

1. Super elasticity+shape memory

There is almost no permanent deformation after being subjected to force compression and bending; Reaching the phase transition temperature can restore the preset shape, and can be used as a hot driven self-cleaning filter. It can deform and shake off clogged impurities when heated, reducing cleaning frequency. Elasticity is several times that of stainless steel, it is resistant to fluid impact, fatigue, and is not easily broken by repeated deformation.

2. Excellent corrosion resistance

Acid and alkali resistant, salt spray resistant, and partially corrosive oil and gas resistant, superior to 304/316 stainless steel, suitable for harsh chemical conditions; A titanium oxide passivation film is formed on the surface to suppress the precipitation of metal ions.

3. Good biocompatibility

Medical grade nickel titanium meets the ASTM-F2063 standard, can be sterilized under high temperature and pressure, and can be used for medical fluid filtration components.

4. Multiple processing forms

Plain weave, twill weave, and gas-liquid foam net (knitted gas-liquid net) can be made into sheets, cylindrical filter cartridges, filters, and shaped parts.

Nickel titanium alloy filter screen

📏 Conventional Specifications

-Wire diameter: 0.05-0.8mm

-Aperture: 50-500 μ m, customizable with micrometer level precision

-Weaving: plain weave, twill weave, knitted vapor-liquid mesh; Can be welded, stamped, and coiled for processing

-Phase change temperature: adjustable according to demand (key parameters of self-cleaning filter)

🧪 Main application scenarios

1. Chemical and petroleum industry: gas-liquid dehazing, oil and gas separation, acidic/sulfur-containing media, distillation tower foam capture net, utilizing memory effect to achieve backwash self-cleaning and extend service life.

2. Medical equipment: Minimally invasive instrument filtration components, vena cava filters, stone retrieval baskets, liquid medicine filtration, capable of repeated high-temperature sterilization.

3. Special industries: filter elements for highly corrosive fluids, pulse alternating pressure conditions, and high fatigue resistance requirements.

>  ⚠️ Many oil fume purifiers on the market are labeled as "nickel titanium alloy filters", but some are actually coated with ordinary stainless steel instead of genuine nickel titanium memory alloy. Purchasing requires verification of material certification.

⚖️ pros and cons

✅ Advantages: deformation rebound, fatigue resistance, corrosion resistance, self-cleaning design, sterilization capability

❌ Disadvantages: High material cost; The phase change temperature parameters need to be matched with the operating conditions; The welding process is more difficult than ordinary stainless steel.

📌 Key selection points

1. Distinguish between industrial grade and medical grade nickel titanium, and in medical scenarios, the ASTM F2063 medical grade must be used;

2. The self-cleaning plan should specify the phase transition temperature and match the operating temperature of the equipment;

3. Verify the wire diameter, aperture, and weaving structure, request material testing reports to avoid being impersonated as materials.
