High Strength Low Density Titanium Round Bar Ø4mm x 250mm - China Suppliers & Factory Direct Offering
Product Description
Titanium Round Bar Key Features
Density is only 60% that of steel (approximately 4.5g/cm³). Still, its strength is comparable to that of steel (e.g., TC4 alloy has a tensile strength of≥ 895MPa), making it an ideal material for aerospace lightweighting.
Dense oxide film (TiO₂) is formed on the surface, which can resist seawater, chlorine ions, acid, and alkali media (especially resistant to chloride corrosion), with a life span far exceeding that of stainless steel.
Non-toxic and compatible with human tissues, it is the preferred material for implantation of medical devices (e.g., artificial joints, bone nails).
Operating temperature up to 400-600°C (e.g., Ti-6Al-4V), suitable for high temperature components such as engines.
Small thermal deformation, suitable for precision instruments; non-magnetic, used in MRI equipment, submarines, and other electromagnetic-sensitive environments.

Applications
Structural components: aircraft landing gear, engine compressor blades, rocket casings (weight reduction to improve fuel efficiency, Boeing 787 titanium usage of 15%).
Fasteners: high-strength bolts, rivets (anti-fatigue, high-temperature resistance, to protect flight safety).
Orthopedics: artificial hip joints, spinal rods, dental implants (close to the modulus of elasticity of bone tissue, reducing “stress shielding”).
Cardiovascular: heart stents, surgical instruments (anticoagulant + non-allergenic).
Deep-sea equipment: submarine pressure-resistant shells, seawater pipes, valves (seawater corrosion resistance, life expectancy of 30 years or more).
Ship components: propeller shafts, heat exchangers (resistant to marine microbial corrosion).
Corrosion-resistant equipment: reactors, pumps, and valves, electrolyzer (alternative to stainless steel to deal with hydrochloric acid, wet chlorine gas, and other media).
Nuclear power: nuclear waste containers (resistance to radiation + long-term stability).
Racing/Sports equipment: bicycle frames, golf clubs (high rigidity, weight reduction to enhance performance).
3D printing: titanium alloy powder printing of customized parts (medical implants, aerospace complex structures).
Processing and selection recommendations
Commonly used grades:
Industrial pure titanium (Gr1-Gr4): corrosion resistance priority (chemical piping).
Ti-6Al-4V (Gr5): high-strength mainstay (aerospace/medical).
Surface treatment:
Anodized (enhanced wear resistance), sandblasted (medical roughness to promote bone integration).
Alternatives:
Titanium-clad steel (composite construction) or high-nitrogen stainless steel for cost-sensitive scenarios.
Frequently Asked Questions
What makes Titanium Round Bars suitable for aerospace applications?
Titanium round bars offer an exceptional strength-to-density ratio (density is only 60% of steel), high-temperature stability up to 400-600°C, and fatigue resistance, making them ideal for critical structural parts, landing gears, and fasteners in aircraft.
Are titanium bars corrosion resistant in marine environments?
Yes. Titanium forms a dense, protective oxide film (TiO2) on its surface, providing extreme resistance to seawater, chlorine ions, and acidic/alkaline media, far exceeding the lifespan of stainless steel in marine engineering.
Why is titanium preferred for medical implants?
Titanium features outstanding biocompatibility, meaning it is non-toxic, non-allergenic, and does not trigger rejection reactions in the human body. It also has an elastic modulus close to bone tissue, reducing stress shielding.
What is the difference between pure titanium and Ti-6Al-4V (Gr5)?
Industrial pure titanium (Gr1-Gr4) is selected primarily for maximum corrosion resistance (e.g., chemical piping). Ti-6Al-4V (Gr5) is an alloy designed for high tensile strength (≥ 895MPa) and structural load-bearing applications.
What surface treatments are available for titanium round bars?
Common surface treatments include annealing and polishing for general use, anodizing to enhance wear resistance, and sandblasting to create surface roughness that promotes bone integration in medical implants.
