How Can Titanium Sheet Bend? I Titanium Sheet Bending Technology

Many customers need to bend titanium sheets into specific shapes. When doing so, however, certain considerations need to be kept in mind as there could be risks of fracture with titanium and titanium alloy sheets that require processing.

1，Characteristics of Titanium that Make it Bendable

Titanium is a metal that is known for its strength and durability, but it is also surprisingly flexible and bendable. Here are some characteristics of titanium that make it bendable:

（1）Ductility: Titanium is a ductile metal, meaning that it can be stretched and deformed without breaking or cracking. This makes it a great choice for applications where flexibility is needed, such as in aircraft and spacecraft components.

（2）Low modulus of elasticity: The modulus of elasticity refers to a material's ability to resist deformation under stress. Titanium has a relatively low modulus of elasticity, which means that it can be deformed more easily than other metals.

（3）High strength-to-weight ratio: Despite its flexibility, titanium is still incredibly strong. Its high strength-to-weight ratio means that it can withstand a lot of stress without becoming deformed or breaking.

（4）Resilience: Titanium is a resilient metal, meaning that it can return to its original shape after being bent or deformed. This makes it an ideal material for applications where repeated bending or flexing is required.

 

2.the basic principles of titanium plate bending

(1)When bending with greater yield strength, additional force should be exerted during bending.

(2)As more titanium is added, its elongation decreases, with material breaking beyond this elongation at smaller bending radiuses.

 

3, bending titanium plate matters to be considered

choose the right tool: titanium plate belongs to the high strength, high toughness material, so bending titanium plate need to choose the right tool, such as hydraulic bending machine or pneumatic bending machine, to ensure the strength and appearance quality after the bending is completed.

(2) Determine the bending angle: Before bending the titanium plate, the exact bending angle must be determined in advance to ensure that the final product meets the design requirements.

(3)A Chinese standard called GB/T 3621 indicates the mechanical properties of titanium and its alloys as being essential:

If the thickness of pure titanium titanium plate is under 6 mm, heating may not be required to bend more than 90 degrees. If heating is necessary, uniform heating of all sheet up to approximately 100-300 degrees may also be necessary

Always aim not to go beyond your desired output in order to prevent hydrogen peroxide embrittlement and changes in chemical and mechanical properties of materials.

The yield strength of titanium plates varies depending on their type.

(4) Control bending strength: When bending titanium plates, attention needs to be paid to controlling the bending strength to ensure that no damage such as rupture or shear will occur.

(5). Avoid collision and friction: In the operation process to avoid collision or friction between the titanium plate and other hard objects, so as not to damage the surface quality.

(6). Keep the surface of the titanium plate clean: Before bending the titanium plate, you need to clean and check the surface of the titanium plate for impurities or cracks and other problems to ensure the quality of the bending process.

(7) Maintain a good working environment: When bending titanium plates, you should maintain a good working environment to avoid dust, moisture, grease and other pollutants affecting the surface quality of the titanium plates.

4.There are several methods for bending titanium plate, including:

(1) Press Brake Bending: This is a common method used in metal fabrication where the titanium plate is clamped between a punch and a die, and then bent to the desired angle.

(2)Roll Bending: In this method, the titanium plate is passed through a series of rollers to achieve the desired curvature.

(3)Heat Bending: This method involves heating the titanium plate to a specific temperature and then bending it to the desired shape. And This method requires hydraulic bending machine or pneumatic bending machine.

(4)Incremental Bending: This method involves bending the titanium plate a little bit at a time, using a press brake or other bending tool, until the desired shape is achieved.

It is important to note that titanium has a high strength-to-weight ratio, which makes it more difficult to bend than other metals. Therefore it is important to use appropriate equipment and techniques to ensure the quality of the bend and avoid damage to the titanium plate.
