Titanium foil and titanium coil are the core forms of titanium processed materials, which have become key materials in the fields of new energy, chemical industry, aerospace, 3C electronics, etc. due to their four characteristics of lightweight, high strength, ultimate corrosion resistance, non-magnetic, and biocompatibility. The global market is growing at a steady pace, with a global titanium coil market size of around USD 893 million by 2025 and the sales of titanium foil in China reaching 6200 tons; The worldwide average growth rate is anticipated to grow at 5.7% from 2026 to 2030 led by the increase of demand for high-end precision foil materials and wide titanium coils. The product meets ASTM B265 American standard and the main grades are GR1/GR2 (pure titanium), GR5 (titanium alloy), and GR7 (corrosion resistant titanium), which can be used in different working conditions.
1, Thickness definition and American standard specification (ASTM B265)
Titanium foil and titanium coil are divided based on thickness as the core standard, and width and length can be customized. The core parameters are as follows:
1. Titanium foil
Thickness ≤ 0.1mm, ultra-thin specification up to 0.005mm (5 μ m), width 10-300mm, length ≥ 500mm, in cold rolling and annealing state, surface roughness Ra ≤ 0.2 μ m.
2. Titanium Coil/Trip
Thickness 0.1-4.75mm, width 50-1500mm, length in rolls (cut as needed), divided into two states: cold rolled glossy surface and annealed oxidized surface.
| Grade | Grade | Tensile strength(MPa) | yield strength(MPa) | elongation(%) | Applicable Temperature(℃) |
|---|---|---|---|---|---|
| GR1 | TA1 | ≥240 | ≥170 | ≥24 | ≤200 |
| GR2 | ≥345 | ≥275 | ≥20 | ≤250 | |
| GR5 | Ti-6Al-4V | ≥895 | ≥828 | ≥10 | ≤300 |
| GR7 | Ti-0.2Pd | ≥345 | ≥275 | ≥20 | ≤250 |
