CNC Machining In Titanium
Titanium is commonly used in the aerospace and medical industries because of its excellent strength-to-weight ratio and high corrosion resistance, such as various titanium fasteners.
Its low thermal expansion and biocompatibility make it a popular material for medical implants.
Precision Machining in Titanium
Due to its strong nature, titanium cannot be easily cast and is mainly used in CNC machining and prototyping.
As a seasoned precision parts factory in China, it has always been our company’s aim to provide our valued customers with a full range of quality custom machining services.

Titanium Grade & Properties
Titanium Grade 1
Grade 1 titanium is commercially pure titanium and is the most ductile of all titanium grades.
As such, it is widely suitable for the manufacturing of plate heat exchangers.
| Grade | Ultimate Tensile Strength | Tensile Strength, Yield | Elongation(%) | Hardness |
|---|---|---|---|---|
| Grade 1 | 240 MPa | 170 - 310 MPa | 24% | 120 HB |
Titanium Grade 2/CP3
Grade 2 titanium has quite outstanding corrosion resistance.
It is often used in applications where water corrosion resistance is required, such as in manufacturing pipes and fasteners, compared to Grade 5 titanium (Ti 6Al-4V).
| Grade | Ultimate Tensile Strength | Tensile Strength, Yield | Elongation(%) | Hardness |
|---|---|---|---|---|
| Grade 2 | 344 - 420 MPa | 275 - 410 MPa | 20 -23% | 80 - 82 HRB |
Titanium Grade 5/Ti 6Al-4V
Titanium Grade 5 or Ti 6Al-4V is the most widely used of all titanium alloy grades and also accounts for almost 50% of aerospace applications.
Ti 6Al-4V has good thermoforming properties, however, its cold forming properties are somewhat limited.
| Grade | Ultimate Tensile Strength | Tensile Strength, Yield | Elongation(%) | Hardness |
|---|---|---|---|---|
| Grade 5/Ti 6Al-4V | 950 MPa | 880 MPa | 14% | 334 HB |
Industry Applications for Titanium
Titanium is one of the more advanced materials with superior nature corrosion resistance, biocompatibility and strength-to-weight ratio mechanical properties.
These unique properties make it ideal for applications in industries such as medical, automotive, chemical processing and aerospace & defense.
Consumer Goods
Titanium is used in the sporting goods because of its high strength-to-weight ratio. It has gradually expanded from the earliest tennis racket to various consumer goods such as bicycle frames, golf heads and clubs, as well as eyeglass frames.
Medical
The good biocompatibility of titanium with human tissues makes it widely used in the medical field, for example: the component parts made of titanium alloys that mimic human tissues, like femoral head, knee, elbow and shoulder joint.
Marine Engineering
Given the advantage of excellent corrosion resistance of titanium and titanium alloy to seawater, they are widely used in nuclear submarines, deep submersibles, icebreakers, hovercraft, propellers, seawater pipes, condensers, heat exchangers, etc.
Chemical
Due to its superior natural corrosion resistance properties, titanium is often used as an alternative for stainless steel, nickel-based alloys, and other rare metals in chemical production, and has become one of the primary anti-corrosion materials for chemical equipment.
Aerospace
Due to its high to strength ratio and high corrosion & temperature resistance, titanium is widely used in aviation applications, such as rotors, compressor blades, and hydraulic system components, aerospace fasteners, as well as engine components.
Automotive
Automotive Light weighting is the trend of the future. And the preferred way to achieve this goal is to use titanium or magnesium or other high-strength lightweight materials to replace traditional steel materials. For example: racing car component parts made of titanium.
Surface Finish for Titanium Parts
Titanium can also be bead blasted or tumbled to achieve a variety of surface finishes.
For example, surface hardening and anodizing are two of the most popular finishes methods.
Surface hardening: When it comes to surface contact or relative motion, its poor wear resistance and surface integrity can lead to surface galling and seizing. Therefore, surface hardening of Titanium becomes particularly necessary to minimize wear between components in similar applications.
Anodizing: In terms of titanium, anodizing not only enhances its resistance to oxidation and wear, but also gives it a range of beautiful colors. It is better to do bead blasting before anodizing.
Cost-saving Advice
Titanium is an expensive material, so the cost of the material should be taken into account along with the proper design.
The following are the two tips we give.
Material selection: Based on the actual application requirements of the product to serve as the basis for selecting the material.
The right choice of material can create the best cost-effective solution that meets the needs and does not produce waste.
Design principles: Titanium is easier to machine compared to other high hardness steels, but because it is expensive, the scrap and reject rate from being machined should be minimized.
Therefore, it is especially important to follow DFM principles. Poorly designed parts can increase machining difficulty and time, which can result in higher costs.
