Advantages
Unique Advantages of Titanium Hexagon Button Head Screw Material Properties
Low Density
The density of titanium alloy is approximately 4.51g/cm³, only 57% of steel’s density (7.8g/cm³), resulting in a significant reduction in weight for the same volume.
High Strength-to-Weight Ratio
The ratio of tensile strength (≥895 MPa) to density far exceeds that of stainless steel and aluminum alloys, making it ideal for weight-sensitive applications (such as aircraft structures and drone components).
Tensile Strength (Ultimate Tensile Strength, UTS): 895~930 MPa
Yield Strength (0.2% offset): 825~869 MPa
Elongation: Approximately 10%~15%
After Solution and Aging Treatment
Through heat treatment (such as β-annealing + aging), the tensile strength can be further improved to 1000~1100 MPa, although the elongation slightly decreases (6%~10%).
Key Features and Advantages
Aesthetic and Low-Profile Design
The button head design is smoother than standard cylindrical or countersunk heads, offering a simple and streamlined appearance, making it ideal for applications that require a sleek surface.
The low head height saves space, making it suitable for assembly environments with limited thickness.
Structural Design
Button Head: A low-profile dome design that is both aesthetic and space-saving, making it perfect for compact assemblies.
Hex Socket Drive: Provides higher torque transfer capability and is more slip-resistant compared to cross-slot drives.
Precision Threads: High-precision rolled threads and CNC machined threads ensure tight engagement and excellent anti-loosening performance.
Preload and Contact Area
The button head features a small flat or curved surface at the bottom, providing moderate contact pressure. This design distributes stress more evenly than countersunk screws but focuses it more than large button head screws.
Outstanding Corrosion Resistance
Due to titanium's chemical properties, its surface naturally forms a stable oxide film that acts like a strong "armor," effectively resisting corrosion from seawater, acids, alkalis, and other aggressive media.
In marine engineering, whether in shipbuilding or offshore oil platform construction, titanium hexagon button head screws, with their exceptional corrosion resistance, can work in harsh marine environments for extended periods, greatly reducing the frequency of maintenance and replacements caused by corrosion, thereby lowering maintenance costs. In the chemical industry, titanium hexagon button head screws also excel in withstanding highly corrosive substances, ensuring safe and stable equipment operation.
Excellent High- and Low-Temperature Performance
In extremely low-temperature environments, such as low-temperature fuel storage equipment in aerospace, titanium hexagon button head screws retain excellent mechanical properties and do not become brittle, ensuring safe equipment operation.
In high-temperature environments, such as component connections in aircraft engines, titanium hexagon button head screws maintain their strength and hardness, with a small thermal expansion rate and excellent high-temperature stability, providing solid support for the efficient operation of equipment.
Low Magnetism and Excellent Biocompatibility
Titanium alloys have extremely low magnetic permeability, making titanium hexagon button head screws ideal for use in precision instruments and electronic devices, where sensitivity to magnetism is critical. This effectively prevents magnetic interference that could affect the precise operation of equipment.
Additionally, titanium alloys are highly biocompatible with human tissues and do not trigger rejection responses. In the medical field, titanium hexagon button head screws are used in orthopedic implants, such as artificial joint fasteners and dental implants, where they integrate seamlessly with human tissue, supporting patient recovery and enhancing quality of life.
