Titanium Coil
Welcome to Titanium China’s definitive guide on Titanium Coil – the epitome of strength, versatility, and innovation. As a leading manufacturer of titanium products, we take pride in offering top-tier titanium coil solutions that cater to various industries worldwide.
What is Titanium Coil?
Titanium coil is a crucial component in numerous industrial sectors, renowned for its exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility. At Titanium China, our coils are meticulously crafted using premium-grade titanium, ensuring unparalleled durability and performance in diverse environments.
Advantages of Titanium Coil
The surface finish of titanium sheets & plates plays a crucial role in their performance and aesthetic appeal. At Titanium China, we offer various surface finishes, including:
- As-rolled: This is the natural surface finish obtained after the rolling process. It has slight variations in texture and color, providing a unique appearance.
- Bright annealed: This finish involves annealing the titanium sheet at high temperatures, resulting in a smooth, shiny surface. It is suitable for applications requiring a polished look.
- Pickled and passivated: This process involves removing the oxide layer from the surface of the titanium sheet, followed by a passivation treatment to protect against corrosion. It results in a uniform, silver-gray appearance.

Titanium coil production process typically involves the following steps:
- Raw material preparation: Titanium coil is made from titanium ingots or sponges, which are melted and refined to create a pure titanium metal.
- Melting and casting: The titanium ingots are melted in a vacuum arc furnace, where they are cast into rectangular billets.
- Hot rolling: The billets are then hot-rolled into thin sheets using a rolling mill. This process requires high temperatures and pressure to shape the titanium into coils.
- Annealing: After hot rolling, the titanium coils are annealed to relieve stress and improve their ductility. This involves heating the coils to a specific temperature and then cooling them slowly.
- Cold rolling: The annealed coils are cold-rolled to further reduce their thickness and improve their strength.
- Surface treatment: The coils may undergo surface treatments such as pickling, passivation, or anodizing to enhance their corrosion resistance and appearance.
- Cutting and packaging: Finally, the coils are cut to size and packaged for shipment or storage.
