Products Description
Titanium foil is produced by cold rolling industrial pure titanium grades 1-4 or alloys like Ti-6Al-4V into strips. Of all the alloys, it have the highest resistance to weight and corrosion.
Titanium foil have width of 600mm, while length is customizable, thickness varies between 0.001 and 0.02 inches and weight can be upto 100kg. Foils have a purity of 99.7% and conform to standards GB/T3622-2012 and ASTM B265. Main application of titanium foil is in aerospace, nuclear power, electronics, chemical industries, precision manufacturing, medical and pharmaceutics.
Features of Titanium Foil Coil:
| Characteristics | Value/Performance | Comparison with Other Metal Foils |
|---|---|---|
| Density | 4.51 g/cm³ (pure titanium) | 43% lighter than stainless steel |
| Tensile Strength | 240-1000 MPa (varies with alloy) | Higher than aluminum foil, close to stainless steel |
| Corrosion Resistance | Resistant to seawater, chloride ions, body fluids | Much better than aluminum/copper foil |
| Biocompatibility | Non-toxic, implantable in the human body | The only one meeting medical Class III implant standards |
| Thermal Conductivity | 17-22 W/(m·K) | Only 1/20th of copper's |
| Operating Temperature | -250°C to 600°C (pure titanium) | Better low-temperature performance than most metals |

FAQ of Titanium Foil Coil
What is the standard thickness range of titanium foil?
A:The conventional thickness is 0.01-0.2mm, and special applications can be customized:
Ultra-thin foil: 0.005-0.01mm (special rolling process required)
Thick foil: 0.2-1.0mm (for structural parts)
How to choose the main grades of titanium foil?
| Grade | Features | Typical Applications |
| Gr1 (Pure Titanium) | High ductility, corrosion resistant | Chemical linings, medical implants |
| Gr5 (Ti-6Al-4V) | High strength | Aerospace structural components, bone screws |
| Gr7 (Ti-0.2Pd) | Resistant to crevice corrosion | Seawater desalination equipment |
| Nitinol (Ti-Ni) | Shape memory effect | Vascular stents, eyeglass frames |
What is the temperature limit of titanium foil?
Short-term use: pure titanium foil can reach 600°C (oxidation begins to be significant), alloy foil (such as Gr5) to 800°C.
Long-term stability: Recommended temperature for pure titanium is ≤300°C and for Gr5 is ≤450°C (strength decreases at high temperatures).
What is common surface treatment processes for titanium foil ?
| Process | Effect | Application Scenarios |
|---|---|---|
| Electrolytic Polishing | Ra ≤ 0.1μm, mirror-like finish | Medical implants, semiconductors |
| Sandblasting | Ra 1.0-3.0μm, increased adhesion | Coating substrates, bonding pretreatment |
| Anodizing | Colored oxide film, improved wear resistance | Decorative components, electronic casings |
