What it is
Cars need strong parts. Engine. Suspension. Drivetrain. Valves. Connecting rods. Springs. Most are steel. Steel works. But steel is heavy.
High strength titanium rod for automotive industry replaces steel where weight matters. Racing cars. Sports cars. Motorcycles. High-end performance vehicles.
Half the weight of steel. Same or better strength. No rust. No corrosion.
Why titanium in cars
Steel is 7.8 g/cm³. Titanium Grade 5 is 4.4 g/cm³. A titanium rod weighs 40% less than a steel rod of the same size.
Less weight means faster acceleration. Better handling. Lower fuel consumption.
For high strength titanium rod for automotive industry, the weight savings is the main reason.
Where it goes
Valves. Engine intake and exhaust valves. High RPM. Valve float is a problem. Lighter valves rev higher. Titanium valves. 5mm to 8mm diameter. Machined from rod.
Connecting rods. Rod connects piston to crankshaft. High stress. Titanium rods are lighter. Engine spins up faster. 15mm to 25mm diameter.
Springs. Valve springs. Suspension springs. Lighter springs reduce reciprocating mass. 3mm to 10mm wire from rod.
Suspension links. Control arms. Rod ends. Replace steel with titanium. Save unsprung weight. 12mm to 30mm diameter.
Fasteners. Titanium bolts. Wheel nuts. Caliper bolts. Light and strong. 5mm to 16mm diameter.
For high strength titanium rod for automotive industry, the rod is machined into the final part. Turned. Threaded. Drilled. Then installed.
Grade 5 vs Grade 23 ELI
| Grade | Tensile | Best for |
| Grade 5 | 895-1000 MPa | General automotive |
| Grade 23 ELI | 860-950 MPa | High fatigue, racing |
Grade 5 is the standard. High strength. Good fatigue life. Widely used.
Grade 23 ELI has lower oxygen. Better fatigue life. For racing engines and critical suspension parts.
For high strength titanium rod for automotive industry, Grade 5 covers most applications.
Material specs (Grade 5)
| Property | Value |
| Tensile (min) | 895 MPa |
| Yield (min) | 828 MPa |
| Elongation | ≥ 10% |
| Density | 4.43 g/cm³ |
| Modulus | 110 GPa |
| Hardness | 34-38 HRC |
Common diameters for automotive
| Diameter (mm) | Part |
| 5 – 8 | Valves, small fasteners |
| 8 – 12 | Valve spring retainers, bolts |
| 12 – 16 | Wheel nuts, caliper bolts |
| 16 – 20 | Connecting rod bolts |
| 20 – 25 | Connecting rods |
| 25 – 35 | Suspension links |
| 35 – 50 | Custom racing parts |
Titanium valves
Engine valves are a classic titanium part. Intake valves. Exhaust valves. Titanium is lighter than steel. Lighter valves need weaker springs. Less friction. Higher RPM.
Titanium valves also withstand high exhaust heat. Grade 5 works to 600°C.
For high strength titanium rod for automotive industry, valve blanks are a major product.
Connecting rods
Steel connecting rods work. But steel rods are heavy. The engine has to accelerate that weight with every revolution.
Titanium rods are lighter. Engine revs faster. Less reciprocating mass. Crank bearings last longer.
Titanium rods are common in racing engines. Some high-end production cars use them.
Spring wire
Valve springs. Suspension springs. Titanium wire from rod.
Titanium springs are lighter than steel. Same spring rate. Lower density.
For high strength titanium rod for automotive industry, we draw rod down to wire. Then spring maker coils it.
Fasteners
Titanium bolts. Light. Strong. Corrosion proof.
Wheel nuts. Save unsprung weight. Each nut matters.
Caliper bolts. High strength. Won't rust. Seen on race cars and show cars.
Thread rolling from rod. Grade 5.
Suspension links
Control arms. Rod ends. Tie rods. Replace steel with titanium.
Save unsprung weight. Better handling. Suspension moves faster over bumps.
For high strength titanium rod for automotive industry, suspension parts are machined from 20mm to 35mm rod.
Machining automotive titanium parts
Titanium machines differently than steel. Use carbide tools. Low surface speed. High feed. Flood coolant.
Grade 5 needs sharp tools. No rubbing.
Thread rolling. Not cutting. Rolling is stronger. Better fatigue life.
For high strength titanium rod for automotive industry, we supply rod cut to length. Centerless ground. Ready for your CNC.
Weight comparison
| Part | Steel weight | Titanium weight | Saving |
| Valve (each) | 50g | 30g | 20g |
| Connecting rod | 600g | 350g | 250g |
| Wheel nut | 80g | 45g | 35g |
Saving per valve is small. Times 16 valves. Times 8000 RPM. Adds up.
Cost vs steel
Titanium costs more. A titanium connecting rod is 5-10x the cost of steel.
For a daily driver, not worth it. For a race car, every gram matters.
For high strength titanium rod for automotive industry, the buyers are racers and enthusiasts.
Surface finish
Automotive parts need good surface finish. Polished or ground.
| Finish | Ra | Part |
| Ground | ≤ 0.4μm | Valves, connecting rods |
| Polished | ≤ 0.2μm | Visible parts, fasteners |
We supply rod ground or polished.
Traceability
Mill test reports. Heat number traceable. ASTM B348 cert.
FAQ
Q: Grade 5 or Grade 23 ELI for connecting rods?
A: Grade 5 is fine. Grade 23 ELI for extreme racing engines. Better fatigue life.
Q: Can I use Grade 5 for exhaust valves?
A: Yes. Grade 5 handles exhaust heat. Inconel is better for extreme turbo applications. Grade 5 is fine for NA and mild turbo.
Q: What diameter for a valve blank?
A: Roughly 1.2x the valve head diameter. A 30mm valve needs about 36mm rod.
Q: Do you supply rod in small quantities?
A: Yes. Minimum order is one rod. Motorsports shops buy small quantities.
The bottom line
Race cars need light parts. Production cars are getting lighter too.
High strength titanium rod for automotive industry helps.
Grade 5 for most parts. Grade 23 ELI for racing.
Valves. Connecting rods. Springs. Fasteners. Suspension links.
Half the weight of steel. Same strength.
Faster cars. Better handling.
