Titanium rods, with their characteristics of high strength, lightweight, corrosion resistance, and high temperature resistance, are mainly applied in the field of new energy vehicles in three major areas: core power systems, lightweight structural components, and key functional components. They are important materials for improving the vehicle’s range, safety, and durability.
1、 Fuel cell system
Hydrogen fuel cells are one of the important technological routes for new energy vehicles, and titanium rods are the key basic materials for this system
1. Bipolar plate support skeleton
The fuel cell bipolar plate needs to work in a highly corrosive hydrogen oxygen reaction environment. After processing, pure titanium or titanium alloy rods can be used as the supporting skeleton of the bipolar plate, replacing traditional stainless steel. Not only does it have stronger corrosion resistance, but it can also reduce the weight of the electrode plate and improve the power density of the fuel cell stack.
2. Hydrogen delivery pipeline connectors
Flanges, joints, and other components made of titanium rods are used to connect hydrogen storage tanks and fuel cell pipelines, effectively resisting the corrosion of high-pressure hydrogen gas, avoiding pipeline leaks, and ensuring system safety.
2、 Power battery system
Titanium rods play an auxiliary role in the structural and functional components of power batteries, enhancing the stability and safety of the batteries
1. Reinforcement ribs/support columns for battery pack shell
The support structure processed with titanium alloy rods can replace some steel, achieve lightweight while ensuring the impact resistance and compression strength of the battery pack, and indirectly improve the vehicle’s range.
2. Components of thermal management system
Titanium rods can be processed into precision valve cores, joints, etc. for battery cooling circuits. They are resistant to coolant corrosion and have stable thermal conductivity, ensuring that the battery operates in a suitable temperature range and extending its lifespan.
3、 Lightweight structural components
The “lightweighting” of new energy vehicles is the key to reducing energy consumption and improving range, and titanium rods are increasingly used in high stress structural components of high-end models
1. Chassis suspension components
After forging and processing, titanium alloy rods can be made into core components such as control arms and steering rods for suspension systems. Compared with traditional steel, they reduce weight by 30% -40% and have higher strength, which can improve the handling and response speed of the chassis.
2. Vehicle load-bearing structural components
In high-end new energy sports cars or special models, titanium rods can be used for load-bearing parts such as body crash beams and door reinforcement ribs. They can effectively absorb energy during collisions, improve the passive safety of the entire vehicle, and reduce the weight of the body.
4、 Motor and Electronic Control System
The working environment of motors and electronic control systems is high temperature and high load, and the high temperature resistance and high strength characteristics of titanium rods are suitable for this scenario:
1. Motor rotor shaft
Some high-performance drive motors use titanium alloy rod processed rotor shafts, which are lighter in weight and have smaller moment of inertia compared to alloy steel shafts. This can improve the motor’s speed limit and response speed, and enhance the vehicle’s acceleration performance.
2. Cooling components of the electronic control system
The heat dissipation fin bracket and precision fastener made of titanium rod are used for the heat dissipation system of the electronic control module. They are resistant to high and low temperature cyclic corrosion, ensuring long-term stable operation of the electronic control system.
