Grade 2 Titanium, also known as Commercially Pure Titanium or CP Titanium, is an unalloyed grade of titanium that is essentially 99% pure titanium.
What is Grade 2 Titanium
This composition gives it unique stability, corrosion resistance, and weldability.
Its most notable property is its exceptional strength-to-weight ratio.
Grade 2 Titanium is approximately 50% lighter than most metals with comparable strength, making it a popular choice for the space, automotive, and marine industries.
It also has excellent corrosion resistance, especially in extreme conditions with seawater and certain chemicals, making it ideal for desalination plants, chemical plants, and equipment involving seawater.
Additionally, it is weldable and can be easily joined without compromising its structural integrity.
The material is also biocompatible, making it ideal for medical implants, surgical tools, and other medical-related devices.
Grade 2 titanium is known for its versatility and balanced performance, which offers unique advantages over other titanium grades.
Of the four commercially pure titanium grades, each grade has different applications based on its mechanical properties and uses.
Titanium Grade 1: The softest and most ductile commercially pure titanium grade, often used in chemical processing equipment, medical devices, and where corrosion resistance and high formability are required.
Titanium Grade 3: Has higher strength but lower ductility than Grade 2 titanium alloy, suitable for demanding industrial applications that require higher mechanical integrity.
Titanium Grade 4: Is the strongest of the commercially pure titanium grades, while providing exceptional strength, it has poorer formability than other grades.
It is often used in high-pressure environments such as aerospace systems, medical implants, and specialized industrial equipment.
Overall, Titanium Grade 2 offers a perfect balance in applications that require a combination of strength, corrosion resistance, and ease of manufacturing, making it the most flexible choice.
Grade 2 Titanium Alloy Parts
Offering a tensile strength of approximately 344 MPa to 485 MPa, it is able to withstand considerable stress without deforming.
Its elongation ranges from 20% to 30%, providing the ductility required for forming and processing into a variety of components.
With a melting point of approximately 1,670°C (3,038°F), it remains stable even in high-temperature applications.
It also exhibits low thermal expansion, so it is able to maintain its shape and size when exposed to temperature fluctuations, a key requirement for aerospace and industrial applications.
Its outstanding properties include corrosion resistance.
The naturally formed oxide layer on the surface helps the material resist attack by moisture, salt, and other chemicals without oxidation or degradation.
This property makes it an ideal material for marine, chemical, and industrial environments.
In addition, its biocompatibility allows it to be used in the manufacture of medical implants and surgical tools.
It is hypoallergenic and does not react negatively with human tissue, ensuring it is a reliable material for orthopedic and dental implants.
Titanium Grade 2’s specific combination of strength, corrosion resistance, and lightweight properties make it vital in several industries.
One of its main applications is in heat exchangers, where its ability to efficiently transfer heat while resisting corrosion is highly valued.
It is commonly used in chemical plants, power plants, and other systems that require heat exchange.
In the medical field, Titanium Grade 2 is widely used to manufacture orthopedic and dental implants because of its biocompatibility and non-toxicity.
Its ability to bond with human tissue makes it ideal for long-term in vivo use.

Likewise, its lightweight and corrosion-resistant properties make it a preferred material for aircraft structures, where weight reduction is critical for fuel efficiency and performance.
From wing structures to engine components, the material ensures reliable and high performance in extreme flight conditions.
Desalination plants also rely on Titanium Grade 2’s resistance to seawater corrosion.
Pipes, pumps, and heat exchangers in the system use this material to ensure the efficient production of fresh water in coastal or arid areas.
It also has applications in the chemical industry, where it is used to manufacture storage tanks, reactors, and process equipment.
Its resistance to strong acids and corrosive chemicals ensures safety, reduces maintenance, and extends the life of your equipment.
The marine environment is one of the harshest for materials, but Grade 2 Titanium performs well under these conditions.
Its most prized property is its resistance to corrosion from seawater.
While conventional metals may develop vulnerabilities such as rust, pitting and degradation due to exposure to saltwater, Titanium Grade 2 is able to maintain its integrity and performance over time.
It is due to this superior property that it is one of the most popular materials for marine applications, including ship hulls, propeller shafts and underwater systems.
Grade 2 Titanium for marine environments
In addition, Grade 2 Titanium also has excellent impact resistance; it is able to withstand mechanical stress, impact forces and wave pressure without deforming.
These properties ensure that ships, submarines and offshore oil rigs can operate for a long time, reducing maintenance and repair costs.
Another important advantage is its resistance to biofouling.
Materials submerged in seawater tend to attract the growth of algae, barnacles and marine organisms, which can affect performance and require frequent cleaning.
Titanium Grade 2 resists biofouling, reducing the need for frequent maintenance and improving operational efficiency.
Grade 2 titanium is an important material in several sectors.
In aerospace, it is used in aircraft frames, engine components and fasteners, where its light weight, high strength and resistance to extreme temperatures improve overall performance and fuel efficiency.
Aerospace used Titanium alloy
Its presence in commercial and military aviation is essential in the manufacture of advanced aircraft.
In the marine industry, Grade 2 titanium is used in ships, submarines and offshore oil rigs.
Its corrosion resistance to saltwater environments significantly extends the life of the equipment, making it a cost-effective solution for marine operations.
The medical sector also relies on this titanium grade for medical implants, prosthetics and orthopedic devices.
Its compatibility with human tissue ensures long-term safety and comfort.
The energy industry uses Grade 2 titanium in power plants and renewable energy systems.
It is used in components such as heat exchangers, reactor vessels and condensers, where high temperature tolerance and corrosion protection are critical.
The chemical industry also benefits from its ability to resist exposure to corrosive substances, making it ideal for tanks, pipes and process equipment.
The machining of Titanium Grade 2 involves a variety of key processes to maintain its superior standards.
One key process is forging and rolling, which involves compressing and forming the titanium to obtain the desired shape and size.
Rolling refines the thickness and surface quality of the material, making it suitable for specialized applications in aerospace and industrial manufacturing.
Welding is another important process as Titanium Grade 2 can be easily joined while maintaining its strength and integrity.
This allows for the construction of large, complex structures such as aircraft frames and marine components.
Annealing is a heat treatment process that is often used to improve machinability and eliminate stresses caused by machining or forming.
This process also improves the stability and durability of the material.
Due to its tendency to stick to cutting tools, CNC machining of Titanium Grade 2 requires specialized techniques.
