The Most Common Grade Of Titanium For CNC Machining
The choice of grade of titanium for CNC machining will depend on the specific requirements of the application, such as strength, corrosion resistance, biocompatibility, or cost. It is important to consult with a knowledgeable supplier or manufacturer to determine the best grade of titanium for your particular project.
Grade 1 titanium, or commercially pure titanium, is a soft and ductile titanium alloy consisting of 99% titanium with trace amounts of other elements.
It is highly resistant to corrosion and often used in the medical and dental industries due to its excellent biocompatibility. With a density of 4.51 g/cm³ and a tensile strength of 240 MPa, it is one of the softest and most ductile titanium alloys, making it easy to form and weld.
Grade 1 titanium is ideal for CNC machining medical implants, orthopedic devices, dental implants, jewelry, and architectural components.
Grade 2 Titanium is widely used for CNC machining due to its excellent properties, including high strength, good corrosion resistance, and weldability. This commercially pure alloy contains around 99% titanium, along with small amounts of oxygen, iron, carbon, and nitrogen.
With a density of 4.5 g/cm³ and a tensile strength of 275 MPa, Grade 2 titanium is stronger than many metals like aluminum and copper. It also resists corrosion in various environments, such as seawater, chlorides, and acids.
These desirable qualities make Grade 2 titanium ideal for many CNC machining applications, including aerospace, medical, and automotive industries. Examples of components that can be machined from Grade 2 titanium include aircraft parts, medical implants, and marine equipment.
Grade 5 Titanium, or Ti6Al4V, is a popular titanium alloy for CNC machining due to its exceptional combination of properties. With 6% aluminum, 4% vanadium, and 90% titanium, it has a density of 4.43 g/cm³ and a tensile strength of 880 MPa, making it one of the strongest titanium alloys available.
Grade 5 titanium is highly resistant to corrosion in various environments, such as seawater, acids, and alkalis. It is suitable for a wide range of CNC machining applications in aerospace, automotive, and medical industries, including engine components, aircraft structural parts, and medical implants.
However, due to its high strength and hardness, it is more difficult to machine than other titanium alloys.
Grade 9 titanium, also known as Ti-3AL-2.5V, is a well-balanced titanium alloy that’s popular for CNC machining. It contains 3% aluminum, 2.5% vanadium, and 94.5% titanium, offering good strength, toughness, and workability.
With a density of 4.48 g/cm³ and a tensile strength of 900 MPa, Grade 9 titanium is stronger than Grade 1 and 2 titanium alloys. It also has good corrosion resistance, fatigue strength, and weldability.
These properties make Grade 9 titanium ideal for CNC machining applications, such as aerospace, marine, and sports equipment. Parts like aircraft components, bicycle frames, and propeller shafts can be produced from Grade 9 titanium using CNC machining. Compared to Grade 5 titanium, it is easier to machine, making it a preferred choice for some applications.
Grade 23 Titanium, also known as Ti6Al4V ELI, is a popular titanium alloy for CNC machining in medical and dental industries due to its biocompatibility and excellent mechanical properties. This alloy contains 6% aluminum, 4% vanadium, and 0.13% oxygen, and is considered to be an extra low interstitial (ELI) grade.
Grade 23 titanium has a density of 4.43 g/cm³ and a tensile strength of 1,120 MPa, making it stronger than Grade 5 titanium. It is also highly resistant to corrosion in various environments, including seawater, acids, and alkalis.

Surface Finishes For CNC Machined Titanium Parts
a range of Anodizing, Polishing, Passivation, Bead Blasted, Powder Coat, and Plating options.
Each finish offers its own advantages – so make sure you select the one that meets all your requirements!
Anodizing
Titanium anodizing is an electrochemical process that creates a controlled oxide layer on the surface of titanium, providing increased corrosion resistance, wear resistance, and the ability to be dyed for aesthetic purposes
Polishing
Titanium polishing is a surface finishing process that uses abrasives to remove imperfections and create a smooth, shiny surface on titanium parts.
Passivation
Titanium passivation is a surface treatment process that involves the formation of a thin oxide layer on the surface of titanium to improve its corrosion resistance and biocompatibility.
Bead Blasted
Titanium bead blasting is a surface treatment process that involves shooting small glass or ceramic beads at high speed against a titanium surface to create a uniform, matte finish with improved texture and reduced reflectivity.
Powder Coat
Powder coating is a process of applying a protective and decorative coating to titanium surfaces by spraying a dry powder onto the surface and then baking it in a high-temperature oven to create a durable and corrosion-resistant finish.
Plating
Process of applying a thin layer of metal onto the surface of the Titanium to improve its appearance, protect it from corrosion and wear, and enhance its conductivity or other properties.

CNC Machining Titanium FAQs
- High-cutting forces: Titanium is a very strong and tough material, which requires high cutting forces to remove material. This can cause tool wear and breakage, as well as put a strain on the machine and its components.
- High heat generation: The high cutting forces generated during machining can also lead to high temperatures, which can cause thermal expansion and distortion of the workpiece. This can also cause tool wear and reduce the overall precision of the machining process.
- Material galling: Titanium has a tendency to adhere to cutting tools during machining, which can lead to galling and built-up edge formation. This can reduce tool life and affect the quality of the machined surface.
The cost of CNC machining titanium can vary depending on a variety of factors such as the complexity of the part, the size of the part, the tolerances required, the number of parts being produced, and the grade of titanium used.
Generally, titanium is a more expensive material than many other metals, which can contribute to the higher cost of CNC machining titanium parts. Additionally, the challenges associated with machining titanium, such as the wear and tear on tools, can also increase the cost.
Grade 5 titanium, also known as Ti6Al4V, is a popular choice for CNC machining due to its excellent strength-to-weight ratio, high corrosion resistance, and good machinability. However, other grades such as Grade 2 and Grade 9 can also be suitable depending on the specific requirements of the part. Ultimately, the selection of the best titanium alloy for CNC machining will depend on factors such as the part’s size, complexity, strength requirements, and corrosion resistance needs.
Carbide inserts: These are the most commonly used cutting tool for titanium machining due to their high wear resistance and toughness.
High-speed steel (HSS) tools: These tools are suitable for lighter machining operations and are less expensive than carbide inserts.
Ceramic inserts: These are very hard and can withstand high temperatures, making them suitable for high-speed machining of titanium.
Polycrystalline diamond (PCD) tools: These are extremely hard and wear-resistant, making them suitable for high-precision machining of titanium.
