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

航空宇宙 Used for critical structural components, aircraft fasteners, and springs where high strength-to-weight ratio is essential.
化学処理： Ideal for pump shafts, valve components, and heat exchanger parts exposed to aggressive media.
海洋工学： 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.

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.
