Baoji Dingding Titanium | Titanium Alloy Forgings · Titanium Cake Multi Field Core Bearing Components

As the core category of forging family, titanium alloy and titanium cake have become key basic components in aerospace, oil drilling, medical equipment, marine engineering and other fields due to their composite advantages of "high strength, corrosion resistance and easy processing". Baoji Dingding Titanium Products Co., Ltd. is based on the foundation of the "China Titanium Valley" forging industry, with mainstream grades such as TC4, TA2, and Ti80 as the core, to create full specification titanium cakes ranging from 50mm to 2000mm. Through the "multi fire forging+precision heat treatment" process, the forging density is achieved to be ≥ 99.9%, fully adapting to the strict requirements of high-end equipment for load-bearing, corrosion resistance, and lightweight.

1、 Core advantage: Why has titanium cake become the core choice in high-end scenarios?

Compared to traditional forgings such as steel and copper plates, titanium alloy titanium plates have intergenerational advantages in key performance dimensions, especially suitable for extreme working conditions and precision machining needs

High load-bearing performance

The tensile strength of TC4 titanium cake is ≥ 960MPa, and Ti80 titanium cake can reach 1100MPa. After forging, the grain size is refined to 3-5 μ m, and the impact toughness is increased by 60% compared to the as cast state. It can withstand high-frequency stress impact during equipment operation.

Global corrosion resistance characteristics

The dense oxide film naturally formed on the surface can resist corrosive media such as seawater, hydrochloric acid, and aviation fuel. The corrosion rate after 5000 hours of salt spray testing is ≤ 0.0003mm/year, far exceeding that of stainless steel forgings.

Significant advantages in lightweight design

The density is only 4.51g/cm ³, which is 60% of the steel cake and 45% of the copper cake of the same specification. It can significantly reduce the weight of the entire equipment and improve the fuel efficiency and load capacity of aviation and aerospace equipment.

Precision machining adaptation

The flatness error after forging is ≤ 0.02mm/m, and the surface roughness Ra is ≤ 1.6 μ m. It can be directly processed by CNC precision machining, reducing subsequent milling and grinding allowances, and lowering customer production cycles and costs.

2、 Mainstream brand and specifications: precise matching of scene requirements

Focusing on commonly used brand names in the market, providing a dual choice of standardization and customization to meet the full scenario needs from general industry to high-end military industry:

Support customization of titanium cakes with oversized specifications (over 2000mm) and irregular cross-sections, with forging forming cycles as low as 15 days. Customized heat treatment solutions such as solution aging and annealing can be provided according to customer needs.

3、 Mainstream market use: full scenario application of titanium cake landing

-Aircraft engine system: TC4 titanium cake is precision processed into compressor disc and turbine disc blanks, which can maintain a stable tensile strength of ≥ 960MPa under high temperature of 400 ℃ and high-speed operation of 15000rpm. Compared with traditional high-temperature alloy discs, it reduces weight by 35% and directly improves engine thrust to weight ratio and fuel efficiency. It has passed 10 fatigue cycle tests by aviation engine manufacturers.

-Spacecraft structural components: Ti80 high-strength titanium cake is used for spacecraft attitude control mechanism turntable and solar panel connection seat, which can withstand the dual tests of extreme temperature difference (-180 ℃~150 ℃) and vacuum environment in space. Its yield strength is ≥ 1000MPa, which can effectively carry the instantaneous impact force during spacecraft orbit change and ensure the accuracy of mechanism operation.

-Aircraft onboard equipment: TC4 titanium cake is processed into radar antenna seats and hydraulic system valve bodies, with a lightweight advantage that reduces the total weight of onboard equipment by 20%. At the same time, it is resistant to aviation fuel corrosion, ensuring no leakage or structural deformation during long-term service.

2. In the field of oil drilling: the "key component" for deep well corrosion environment

In deep well drilling above 3000 meters, the drill pipe joints and stabilizer components made of TC4 titanium cake exhibit excellent corrosion resistance and fatigue resistance:

-Can withstand strong corrosion from sulfur-containing drilling fluids, with a service life more than 8 times longer than steel joints, reducing equipment maintenance costs for deep well drilling;

-The forging has high density, no internal loose defects, and can withstand underground pressure compression of thousands of meters, avoiding drilling accidents caused by joint fracture.

3. Medical device field: Bio friendly "implants and device components"

TA2 and TC4 titanium cakes have become the core substrates of medical devices due to their excellent biocompatibility

-TA2 pure titanium cake is processed into artificial joint acetabulum and dental implant abutment, without nickel or allergenic elements, with a rejection rate of less than 0.1% when implanted into the human body;

-TC4 titanium cake is used for components such as forceps heads and scissor shafts in surgical instruments. It has high strength and resistance to disinfection and corrosion, and can withstand repeated tests of high temperature and high pressure sterilization.

4. Shipbuilding industry: the "corrosion resistance benchmark" for marine environments

Titanium alloy titanium cake, with its composite advantages of "seawater corrosion resistance+high strength", has become a key component for various types of ships, especially high-end special ships, solving the pain points of traditional steel corrosion and high maintenance costs:

-Core components of civil ships: TA2 pure titanium cake is used to make the seawater cooler tube plate and ballast water system flange of large container ships. After 5000 hours of seawater immersion testing, the corrosion rate is ≤ 0.0003mm/year, which extends the service life of copper nickel alloy components by 10 times and significantly reduces the frequency of ship docking maintenance.

-Special ship structural components: TC4 titanium cake is used for the propeller hub and propulsion system drive shaft end plate of scientific research ships and icebreakers. It maintains a toughness of ≥ 12% in polar low temperature (-50 ℃) and high salt spray environments, avoiding the risk of low-temperature brittleness and ensuring safe navigation in extreme sea areas.

-Military ship equipment: Ti80 titanium cake is processed into pressure resistant shell connectors for submarines and torpedo launch tube end caps. Its tensile strength is ≥ 1100MPa, which can withstand deep-sea pressure of 300 meters. At the same time, its non-magnetic properties can reduce the probability of submarine detection and improve concealment.

5. Marine and chemical industries: the "core components" of corrosion-resistant scenarios
