2. Hot rolling:the rolling process performed at a temperature higher than the recrystallization temperature;
3. Cold rolling:the rolling process where the plastic deformation temperature is lower than the recovery temperature;
4. Annealing: slowly heating the metal to a certain temperature, insisting on meeting the time, and then cooling at an appropriate speed a metal heat treatment technology;
5. Pickling: immersing the parts in an aqueous solution such as sulfuric acid to remove the oxide and other thin films on the metal surface. It is the pretreatment or process treatment of electroplating, enamel, rolling and other skills.

titanium alloy plate
Ti6al4v plate
Grade 5 titanium is one of the most commonly used alloys in titanium industry, accounting for 50% of the world titanium consumption. Also known as Ti-6Al-4V (or ti6-4), this name refers to its main chemical composition of 90% titanium, 6% aluminum, 4% vanadium, 0.25% (maximum) iron and 0.2% (maximum) oxygen. It has almost the same high corrosion resistance as pure titanium, but has better strength, low elastic modulus, good weldability and heat treatment. The addition of aluminum and vanadium improves the hardness and physical and mechanical properties of the alloy.
