The global leader in commercially titanium alloy rod manufacturing services
Daxun, specializing in the production of alloy titanium rods for extreme environments
CP Grade 4 titanium bar represents the highest strength variant within the commercially pure titanium family, combining exceptional mechanical properties with outstanding corrosion resistance. As an unalloyed titanium grade, it maintains the inherent biocompatibility and weldability of pure titanium while delivering significantly enhanced tensile strength, with minimum yield strength reaching 480 MPa and ultimate tensile strength exceeding 550 MPa. This unique combination makes CP Grade 4 titanium bars particularly valuable in applications demanding both structural integrity and environmental durability.
The chemical composition of CP Grade 4 titanium bar consists primarily of titanium with controlled amounts of oxygen (0.40% maximum), iron (0.50% maximum), carbon (0.08% maximum), and nitrogen (0.05% maximum). The elevated oxygen content compared to other CP grades directly contributes to its superior strength characteristics. These bars exhibit excellent ductility, allowing for various forming processes while maintaining their enhanced mechanical properties, making them suitable for cold working, machining, and fabrication into complex components.
Key Application Areas
- Aerospace: Used for critical structural components, aircraft fasteners, and springs where high strength-to-weight ratio is essential.
- Chemical Processing: Ideal for pump shafts, valve components, and heat exchanger parts exposed to aggressive media.
- Marine Engineering: Employed for hardware and components that require long-term durability in seawater.
- Medical Implants: Utilized for surgical instruments and implant devices that demand both high strength and biocompatibility.
Manufacturing & Product Forms
- Production Processes: Can be produced through hot rolling, forging, or extrusion, followed by annealing.
- Available Forms: Supplied in various shapes, including round, square, hexagonal, and flat bars.
- Custom Dimensions: Available in a wide range of sizes, with options for custom dimensions to meet specific project needs.
- Machining: Can be effectively machined using appropriate tooling and cooling strategies, though it requires more robust parameters than lower titanium grades.

Daxun uses the ERP system to achieve full traceability of the variety, specification, and origin of each titanium rod, and advocates and encourages industry anti-counterfeiting. Daxun relies on technology for processing and customization, and high precision and high quality are the industry benchmarks; in terms of service, it promotes product life cycle management, provides professional material selection and processing solutions before sales, strictly monitors during sales, and provides worry-free service guarantees after sales.
CP Grade 4 Titanium Rod Production Method
Daxun produces high-quality titanium bars with high performance, and can also manufacture according to customer’s agreement:
- Titanium ingots need to go through heat treatment and machining, immersion ultrasonic testing, mechanical properties testing, macroscopic and microscopic structural inspection and other processes. Production process: hot-rolled titanium bars – high efficiency, stable performance, forged titanium bars – flexible size, multi-fire forging, improve the comprehensive performance of titanium bars, cold-drawn titanium bars – usually small-sized high-precision titanium bars; the above titanium bars are all delivered with bright surface.
Quality, delivery, inspection
Daxun performs several quality assurance tests, these tests include mechanical tests like area tensile, chemical analysis, material positive identification – PMI test, micro and macro testing, intergranular corrosion (IGC) test, ultrasonic flaw detection test, pitting and resistance test, hardness test, material positive identification, expansion test etc. All these tests ensure that the CP Grade 4 Titanium Rod and CP Grade 4 Titanium Round Bar material is suitable for the required application. During the production process, we measure the diameter, thickness and surface of the product.

Recent hot case projects and products
CP Grade 4 is the strongest of all the commercially pure titanium grades. Its key differentiator is its higher oxygen content, which gives it a minimum yield strength of 480 MPa, significantly higher than CP Grade 2 (275 MPa). This makes it the preferred choice when high strength and durability are critical, while still maintaining excellent corrosion resistance.
Due to its high strength-to-weight ratio and biocompatibility, CP Grade 4 titanium bar is widely used in the aerospace industry for fasteners and springs, in chemical processing for pump and valve components, in marine engineering for durable hardware, and in the medical field for surgical instruments and implants that require superior structural integrity.
While it is more challenging to machine than lower grades due to its strength, it can be effectively machined with proper tooling and cooling. It is also readily weldable using standard methods like TIG welding, but it requires an inert gas shield (like argon) to protect the weld area from atmospheric contamination and prevent embrittlement.
The primary advantage is its superior corrosion resistance, especially in chloride environments like seawater, where stainless steel is prone to pitting and stress corrosion cracking. CP Grade 4 also offers a much better strength-to-weight ratio. Although the initial cost is higher, its extended service life and reduced maintenance in harsh environments often result in a lower total cost of ownership.
