Pure titanium forgings are mainly made of titanium element, containing only trace amounts of impurities such as oxygen and iron. Common grades are TA1 and TA2; Titanium alloy forgings add alloying elements such as aluminum, vanadium, and molybdenum to titanium substrates, with the typical grade being TC4. The core differences between the two are reflected in their composition, properties, processes, and applications.

In terms of mechanical properties, pure titanium forgings have a soft texture and low tensile strength, but excellent plasticity and ductility, and are easy to bend and form; Titanium alloy forgings are strengthened by alloys, resulting in significantly improved strength, hardness, and wear resistance. They also have stronger fatigue and impact resistance, can withstand high pressure and alternating loads, and are less prone to deformation and cracking.

In terms of corrosion resistance, pure titanium forgings have extremely strong resistance to acid, alkali, and seawater corrosion, and outstanding chemical stability; The corrosion resistance of titanium alloy forgings is slightly inferior to pure titanium, but they have better high-temperature resistance, better structural stability in high-temperature environments, and a wider range of applicable working conditions.

In forging processing, pure titanium has good plasticity, a wide forging temperature range, simple process, and excellent cold working performance; Titanium alloy has high deformation resistance and requires higher temperature hot forging, which makes it difficult to process and more expensive. It has strict requirements for forging technology and equipment.

In terms of application scenarios, pure titanium forgings are commonly used in chemical equipment, seawater treatment, and precision corrosion-resistant components; Titanium alloy forgings focus on high-strength and high load fields such as aerospace, high-pressure machinery, and load-bearing structural components. The two are selected based on strength, corrosion resistance, and load-bearing requirements.
