Maximize Market Research reports that titanium, whose market value is expected to reach $47.96 billion in 2032, has emerged as a key enabler in designing cars with better fuel economy, performance rate, and low carbon emissions. Titanium has been reserved for aerospace and hypercars for decades. But today’s automobile brands are slowly integrating it into consumer cars in various ways. Automakers use titanium to design hardened or durable mechanical parts, like engine valves and connecting rods, suspension springs, turbocharger rotors, and exhaust systems. Another way you interact with this metal in cars unknowingly, is as titanium dioxide, which is found in coatings and paint. While you might not easily notice titanium inside your car, it will continue playing a critical role in making your next ride more efficient, safe, and eco-friendly. In this post, we’ll discuss titanium’s role in mainstream automobiles, from maximizing fleet efficiency and performance to boosting safety and minimizing manufacturing costs.
Reduces Car Weight
With a weight that’s 45% lighter than steel, titanium creates the opportunity to manufacture sleeker and more fuel-efficient cars. In fact, titanium’s lightness minimizes vehicle mass by 40-55%. Look at the 2000 Chevrolet Corvette Z06, for example. It features a titanium muffler and exhaust system that weighs only 11.8 kg. Compared to the stainless steel version of 20kg, a titanium-made exhaust and muffler improves the vehicle’s power-to-weight ratio and exhaust flow. Note: Reducing a car’s weight by at least 10% improves fuel economy by 6% to 8%. Typically, a heavy automobile requires more gasoline or electricity to move. But a lighter one needs less energy, which helps lower fuel consumption or extend an EV’s range.
Supports Innovation and Lowers Production Costs
Purchasing raw titanium is more costly than stainless steel, aluminum, and carbon fiber polymers. However, it has inspired manufacturers to lower production expenses through 3D printing or additive manufacturing. The high strength paired with lightness and design flexibility allows manufacturers to alter the metal’s shape without losing its integrity. For example, Grade 5 titanium (Ti-6Al-4V) has unmatched strength and high corrosion resilience, which makes it the industry standard for additive manufacturing. During production, automakers create geometrical structures or lattices, which can only be done using 3D printing to make lightweight vehicles.
Adopting additive manufacturing reduces material waste, which helps lower production expenses. Since the process involves adding materials to components in the manufacturing phase, minimal waste is produced. For example, when using titanium sheet plate to fabricate battery enclosures, body panels, drivetrain fasteners and nuts, or exhaust systems, manufacturers add the metal plate to the parts piece by piece. The results: automakers only use the material needed for the specific part.
Advanced car manufacturing techniques also support the use of recycled titanium powder to make intricate car components. Manufacturers not only cut production costs but also lower their carbon footprint by leveraging recycled metal. While titanium is tough, it’s recyclable, and that makes it an eco-friendly material that enables the automotive sector to build a sustainable supply chain.
Guarantees Long-term Durability and Safety
Don’t mistake titanium’s light weight for weakness. With a higher melting point than aluminum, titanium withstands extreme temperatures without degrading. Think of engine components, exhaust systems, valve springs, and turbochargers. They endure high heat and repeated motion that wears and tears them quickly. When these components are made using titanium, they function effectively even under extreme environments and don’t degrade.
Besides high heat resistance, titanium resists corrosion and rust, as it naturally creates an oxide layer to prevent a reaction with corrosive elements. Steel suspension springs, struts, shocks, exhaust pipes, undercarriage, and frame are prone to rust caused by moisture and road salt. Titanium’s ability to resist rust guarantees that these safety-critical components don’t weaken or fail prematurely because of extreme weather and cold salt water.
By extending the longevity of vehicle parts, titanium minimizes maintenance costs and the need to replace components frequently. Plus, drivers and passengers don’t have to worry about sudden mechanical failures that could cause fatal accidents and injuries. After all, titanium undercarriages, battery casings, and suspension springs don’t break down quickly because of extreme temperatures or rust. And titanium body panels withstand high-impact crashes, ensuring passengers stay protected in road collisions.
The metal with unmatched strength, heat and rust resistance, and a lightweight has become the industry’s favorite metal for manufacturing next-gen automobiles. While it’s often hard to spot its presence, titanium’s application in cars is vast, from body panels to the chassis, engine components, valve springs, battery enclosures, mufflers, and exhaust systems. Its unique properties allow engineers to use additive manufacturing to design lightweight automobiles that are not only durable but also safe and eco-friendly.
