Titanium Alloys

There are differences between commercial pure titanium and titanium alloy in several aspects. The specific comparison is as follows:

Composition

• Commercial Pure Titanium: It has a relatively high purity, usually containing small amounts of impurity elements such as oxygen, nitrogen, and hydrogen, with titanium as the main component.

• Titanium Alloy: Based on titanium, other alloying elements like aluminum, vanadium, and molybdenum are added to improve its properties.

Performance Characteristics

• Strength: The strength of commercial pure titanium is relatively low; through alloying and heat treatment, the strength of titanium alloy (H2) is significantly increased, enabling it to withstand greater external forces.

• Corrosion Resistance: Commercial pure titanium has good corrosion resistance; titanium alloy (H2) has better corrosion resistance in some complex corrosive environments.

• Heat Resistance: The heat resistance of commercial pure titanium is limited; titanium alloy (H2) can maintain stable performance at higher temperatures.

Processing Difficulty

• Commercial Pure Titanium: It is relatively soft, with a relatively low processing difficulty, and can be processed through various processes such as rolling and forging.

• Titanium Alloy: Due to its high strength and hardness, it is difficult to process, requiring high - end processing techniques and equipment, as well as special cutting tools and process parameters.

Application Fields

• Commercial Pure Titanium: It is often used in fields where high strength is not required, but good corrosion resistance and biocompatibility are needed, such as glasses frames and watches.

• Titanium Alloy: It is widely applied in fields with extremely high requirements for comprehensive material properties, such as aerospace and high - end medical devices.
