Ding Ding Titanium: A Core Supplier of Medical Titanium Alloys in the Medical Device Industry

The safety and reliability of medical devices begin with the stringent control of every raw material. As a national high-tech enterprise specializing in medical titanium alloys, Baoji Dingding Titanium Products Co., Ltd. adheres to the "medical-grade standard" as its core, focusing on the R&D and production of medical titanium alloy rods, plates, wires, and other products. These are widely used in critical medical applications such as orthopedic implants, dental implants, and surgical instruments. The company has become a stable partner for nearly a hundred medical device manufacturers, laying a solid material foundation for the healthcare industry.

1. Focus on three core medical scenarios and accurately match medical device needs

Based on a deep understanding of the medical device industry, the company customizes differentiated medical titanium alloy solutions to meet the performance requirements of different scenarios, ensuring precise compatibility between materials and device functions.

1. Titanium alloy for orthopedic implants: balancing strength and biocompatibility

In the field of orthopedic implants, manufacturers of joint, trauma, and spinal instruments face three core pain points: difficult mechanical matching, high postoperative risks, and large processing losses. Joint implants need to balance load-bearing and wear resistance, trauma fixation materials need to adapt to the shaping needs of different fracture sites, and spinal nail rod systems have strict requirements for dimensional accuracy and biocompatibility. Dingding Titanium Industry deeply cultivates segmented scenarios, based on exclusive medical titanium alloy grades such as TC4, TC20, TC4-DT, etc., providing scenario based solutions:

Regarding pain points for joint customers: Artificial hip joints, knee joints, and other components that are subjected to alternating stress for a long time are prone to wear and tear debris, leading to inflammation. We adopt the dual melting process of "vacuum self consumption+electric slag remelting" to increase the purity of titanium alloy to 99.8% and reduce non-metallic inclusions; By optimizing the microstructure through beta heat treatment, the wear resistance of the alloy is improved by 40%, while controlling the elastic modulus at 110-115GPa, which is closer to human bone (30GPa), significantly reducing the risk of bone atrophy caused by "stress shielding". We can customize titanium alloy rods for joint stem acetabular cups with a diameter of 16-100mm and titanium alloy plates for joint acetabular cups with a thickness of 5-20mm for customers. The surface roughness is controlled below Ra0.8 μ m and can be directly adapted for subsequent coating processing.

Regarding pain points for trauma clients: Trauma instruments such as bone plates and intramedullary nails need to achieve diversified shaping according to the fracture site (such as limbs, pelvis), and need to quickly cooperate with the bone to exert force after surgery. Our TC4-DT low gap titanium alloy rod has a tensile strength of 950MPa, a yield strength of ≥ 860MPa, an elongation rate of over 15%, and a bending angle of 30 ° without cracks, meeting complex shaping requirements; We have established a fast supply chain system with "24-hour inquiry response, 7-day sample delivery, and 15 day mass production" to meet the urgent procurement needs of emergency trauma equipment, and have provided guarantees for emergency medical orders multiple times.

Regarding pain points for spinal clients: The accuracy of the connection between the screws and the rod body of the spinal nail rod system directly affects the surgical effect, and traditional materials are prone to thread slippage or dimensional deviation. We use the "precision grinding+laser diameter measurement" process to control the diameter tolerance of the titanium alloy rod within ± 0.01mm, and the thread accuracy reaches 6g level, ensuring perfect engagement between the screw and the rod body; The biocompatibility of the product has passed the ISO 10993-4 cytotoxicity test and ISO 10993-10 sensitization test, and the incidence of postoperative adverse reactions is less than 0.1%. It has helped multiple customers register their spinal products with NMPA.

After special surface treatment, the product's biocompatibility meets the ISO 10993 standard, with no cytotoxicity or sensitization reactions, and can quickly achieve "osseointegration" with human bones, effectively reducing the risk of postoperative rejection. We can customize titanium alloy rods with a diameter of 2-100mm and titanium alloy plates with a thickness of 0.5-20mm to meet the needs of different components such as spinal nail rods and artificial joint handles. The tolerance is controlled within ± 0.02mm to reduce subsequent processing losses for medical device manufacturers.

2. Titanium alloy for dental implants: suitable for complex oral environments

Dental implants need to be stable for a long time in a humid and acidic oral environment, and must have good aesthetic adaptability. Dingding Titanium Industry has developed TA1, TA2 pure titanium and TC4 titanium alloy wire/rod specifically for dental scenarios, with a purity of over 99.6% and impurity element content far below medical standard limits, avoiding the risk of heavy metal precipitation.

Through precision rolling technology, the diameter accuracy of titanium alloy wire is controlled within ± 0.01mm, and the surface roughness Ra is ≤ 0.4 μ m. This not only facilitates the threading and surface modification of implants, but also improves the adhesion with gingival tissue. The oral corrosion resistance rate of the product is less than 0.005mm/year, and the service life can reach more than 10 years. It has become a core raw material supplier for many dental instrument companies.

3. Titanium alloy for surgical instruments: lightweight and durable, improving operational efficiency

Precision surgical instruments such as surgical forceps, tweezers, and bone drills need to be lightweight, high-strength, and easy to disinfect. The medical titanium alloy plates/wires produced by Dingding Titanium Industry have a specific strength 1.5 times that of stainless steel, reducing the weight of surgical instruments by 30% and effectively relieving hand fatigue during long-term operations.

The material has excellent resistance to moisture and heat, and can withstand 135 ℃ high-pressure steam sterilization and low-temperature plasma sterilization. After repeated sterilization, the mechanical properties do not deteriorate. For the precise requirements of microsurgical instruments, ultra-thin titanium alloy plates with a thickness of 0.1-5mm can be provided, supporting stamping and welding processing of complex shapes, helping instrument manufacturers enhance product competitiveness.

2、 Four core advantages, forging trust in medical grade cooperation

From raw materials to finished product delivery, from technology research and development to after-sales support, Dingding Titanium Industry leverages its full chain advantages to solve material pain points for medical device manufacturers and reduce cooperation risks.
