TA7 titanium alloy is a high-performance metal material widely used in aerospace, medical devices, and automotive manufacturing. Its unique physical and mechanical properties make it excel in high-stress, high-temperature, and corrosive environments.
Overview of TA7 Titanium Alloy
TA7 titanium alloy is a titanium-aluminum-vanadium alloy with a nominal composition of Ti-6Al-4V. It features high specific strength, excellent corrosion resistance, and superior fatigue resistance, making it a crucial engineering material.
Density: Approximately 4.43 g/cm³
Melting Point: Around 1600 °C
Tensile Strength: Up to 895 MPa
Yield Strength: Approximately 830 MPa
Elongation: About 10%
Characteristics of Titanium Bars Produced to Enterprise Standard
This refers to titanium alloy bars manufactured according to specific enterprise standards, primarily for high-precision and high-strength applications.
Diameter Range: Typically between 0.5 mm and 5 mm (customizable).
Key Features: High surface finish, good toughness, and excellent fatigue resistance.
Fatigue Performance
Fatigue performance indicates a material's ability to withstand cyclic loading. It is a critical indicator for the dynamic application of these titanium bars.
Fatigue Limit: At room temperature, the fatigue limit is approximately 620 MPa. This stress level allows the material to endure over 10⁷ load cycles without fracture.
Fatigue Life: Under a stress level of 500 MPa, the fatigue life can reach 10⁶ cycles. Fatigue life increases significantly as the stress level decreases.
Frequency Influence: Tests show that fatigue performance remains relatively stable at frequencies of 10 Hz and 100 Hz, indicating good frequency stability.
Fracture Performance
Fracture performance relates to a material's ability to resist fracture under ultimate load, directly impacting its safety and reliability under extreme conditions.
Fracture Toughness (K_IC): The value is approximately 55 MPa·m⁰.⁵. This signifies high energy absorption during crack propagation, effectively hindering rapid crack growth.
Fracture Elongation: Measured at 15% in tensile tests, demonstrating high plastic deformation capability. The material can undergo some deformation without immediate fracture even under high stress.
Fracture Mode: Scanning Electron Microscope (SEM) observation of fracture surfaces reveals distinct dimple patterns, indicating a primarily ductile fracture mode. This is significant for preventing sudden failure at stress concentration points.
TA7 titanium alloy bars produced to enterprise standard exhibit outstanding fatigue and fracture properties. Its high fatigue limit and long fatigue life make it suitable for applications requiring long-term endurance of cyclic loads. Excellent fracture toughness and plastic deformation capacity ensure reliability under extreme conditions.

Our factory
Our factory operates a dedicated production facility equipped with modern machinery for processing titanium. We have a complete set of equipment including forging presses, hot and cold rolling mills, tube drawing and welding lines, bar & wire drawing machines, and surface treatment units. This allows us to control the production process from raw material to finished products such as sheets, plates, tubes, bars, and wires. Our workshop is capable of handling large-volume orders while maintaining consistent quality across our product range.
Titanium product packaging
Our packaging is designed for maximum security and international standards. We use tailored wooden crates for heavy plates and bars, with internal waterproof wrapping and blocking to prevent movement. Tubes and coils are securely packed in wooden boxes with reinforced edges and protective end caps. For smaller items like wires and strips, we use standard export cartons with inner plastic and moisture-proof sealing. All packages are clearly marked with product details, weight, and handling instructions to ensure safe arrival. We can also customize packing methods, such as palletization or container optimization, based on specific shipping and customer requirements.
