Gr2 ASTM B265 Cold Rolling Titanium Foil Roll

Titanium Foil Roll Gr2 ASTM B265 Foil Roll

The properties of titanium are closely related to temperature, morphology and purity. Dense titanium is fairly stable in nature, but powder titanium can cause spontaneous combustion in air. The presence of impurities in titanium significantly affects the physical, chemical, mechanical properties and corrosion resistance of titanium. In particular, some interstitial impurities can distort the crystal lattice of titanium and affect various properties of titanium. At room temperature, the chemical activity of titanium is very small and can react with a few substances such as hydrofluoric acid, but when the temperature increases, the activity of titanium increases rapidly, especially at high temperature, titanium can react violently with many substances. The smelting process of titanium is generally carried out at a high temperature above 800℃, so it must be operated in a vacuum or under the protection of an inert atmosphere.

Rolling:
The most widely used manufacturing method of titanium foil is flat roll strip rolling, which has high productivity, large scale and output. The basic use of six high cold rolling mill or 20 high cold rolling mill for production.
Heat treatment:
There are two main heat treatment methods for titanium strip foil: vacuum annealing and continuous online protective annealing. Vacuum annealing is to place rolls or sheets of titanium foil in a vacuum furnace for heat treatment. Continuous online protective annealing of Titanium strip foil is a new technology introduced in recent years. Compared with vacuum annealing, it has higher production efficiency and higher quality of products, but the equipment threshold is higher, especially for the quality of products and mechanical properties of titanium strip foil.

Six big features:
1. High strength
2. The corrosion
3. High temperature resistance
4. Good low temperature resistance
5. Environmentally friendly metals
6. Good thermal conductivity
