6mm Titanium Rods

 

6mm titanium rods refer to titanium and titanium alloy rods with a diameter of 6 millimeters; they are a highly representative small-diameter category within the titanium processed materials system. Depending on the degree of alloying and differences in phase structure, these rods can be further classified into several categories, including industrial pure titanium rods (typically represented by Gr1 and Gr2), α-type titanium alloy rods, and (α+β)-type titanium alloy rods (such as Grade 5 Ti6Al4V). These categories exhibit significant differences in composition, properties, and application scenarios.

Combining the core advantages of titanium-low density, high specific strength, excellent corrosion resistance, and biocompatibility-these products are also suitable for applications such as precision machining, small-diameter shafts, fasteners, and implant substrates due to their small-diameter specifications. The products are manufactured in strict compliance with current standards such as ASTM B348, F67, and F136. They can be customized into two main series-pure titanium and titanium alloys-with supply conditions, surface finish, and mechanical properties tailored to meet the specific requirements of industrial, medical, aerospace, and chemical sectors.

 

 

1. Basic Dimensions

- Nominal Diameter: 6 mm (custom sizes available from 5.8 mm to 6.2 mm with non-standard tolerances)

- Standard Length: Standard lengths range from 300 mm to 5,000 mm; custom lengths and short-length cuts are available

- Cross-Section Shape: Solid round bar, free of eccentricity and reduced-diameter defects

2. Dimensional Tolerances and Geometric Accuracy

6mm small-diameter titanium rods adhere to high-precision tolerance standards, categorized into standard and precision grades to meet the needs of various machining applications:

- Standard turned rods: Diameter tolerance ±0.1mm, ovality ≤0.15mm, straightness ≤1mm/m

- Precision ground bars: Diameter tolerance ±0.05 mm, ovality ≤0.08 mm, straightness ≤0.5 mm/m

- Chamfer: End face chamfer ≤0.5 mm, free of burrs and flash

 

 

• Density: 4.51 g/cm³, only 60% that of steel, resulting in significant weight reduction
• Corrosion resistance: The surface naturally forms a passivated TiO₂ film, providing resistance to seawater, acids, alkalis, and chloride ion corrosion, outperforming 316L stainless steel
• Biocompatibility: Non-toxic, hypoallergenic, and non-magnetic; suitable for human implants and medical device components
• Thermal Stability: Melting point of 1668°C; long-term operating temperature range of -250°C to 600°C; excellent low-temperature toughness
• Machinability: Small 6mm-diameter sections are easy to machine, bend, and weld; no tool sticking occurs; high yield rate for secondary processing

 

 

1. Exceptional Corrosion Resistance

Performs excellently in oxidizing, neutral, and chloride-containing environments

Resistance to pitting, crevice corrosion, and stress corrosion cracking far exceeds that of stainless steel

Forms a dense TiO₂ passivation layer (2–10 nm thick) on the surface, with strong self-healing properties

2. High Specific Strength

Specific strength (strength/density) is twice that of steel and 1.3 times that of aluminum

The weight per meter for a 6 mm gauge is only approximately 0.127 kg (Ti6Al4V), offering significant weight-saving advantages

3. Biocompatibility (Medical Grade)

Complies with ISO 5832-2/3 standards for surgical implants

Non-magnetic and non-toxic, with excellent compatibility with human tissue

Modulus of elasticity is close to that of human bone, reducing the stress shielding effect

4. Wide Temperature Range Operability

Low-temperature toughness: Maintains good plasticity at -253°C (suitable for liquid hydrogen/liquid oxygen environments)

High-temperature strength: TI6AL4V can operate continuously at temperatures up to 350–400°C

 

 

(1) Industrial Manufacturing Sector

In the petrochemical industry, 6mm titanium rods are widely used to manufacture corrosion-resistant standard parts, valve cores, pipe fittings, and other components due to their exceptional corrosion resistance. They can operate stably over the long term under harsh conditions involving strong acids, strong alkalis, and high temperatures and pressures, significantly reducing equipment maintenance costs and the risk of downtime^. In the water treatment industry, 6mm titanium rods made of Gr1 material are the ideal choice for manufacturing precision filtration components in reverse osmosis systems and desalination plants. Their resistance to sewage corrosion ensures the long-term, stable operation of the equipment.

In the hardware and electronics sector, small-diameter 6mm titanium rods are used to manufacture precision electrodes, electronic connectors, and other components. Their non-magnetic and high-strength properties effectively prevent electromagnetic interference, enhancing the operational stability and precision of electronic devices. The aerospace sector places extremely high demands on the comprehensive performance of 6mm titanium rods. (α+β) titanium alloy rods, with their high strength and low density, are used to manufacture critical components such as aircraft engine blades and structural fasteners for spacecraft, supporting the trend toward lightweight and high-performance aerospace equipment.

(2) Medical Device Sector

6mm medical-grade titanium rods are one of the core raw materials for orthopedic implants and surgical instruments. TA1 pure titanium rods, due to their excellent corrosion resistance and biocompatibility, are commonly used to manufacture non-load-bearing surgical instruments such as surgical forceps and fixation frames. Meanwhile, Gr5 titanium rods, with their balanced strength and toughness, are the material of choice for load-bearing implants such as spinal screws, intramedullary nails, and artificial joints. Their excellent mechanical compatibility effectively reduces the stress shielding effect and promotes bone healing.

In the dental field, 6mm titanium rods can be machined into dental implant abutments. Their biocompatibility ensures long-term integration between the implant and the alveolar bone, providing stable support for dental restoration. Additionally, in high-temperature sterilization scenarios, 6mm titanium rods treated with a double-annealing process can withstand repeated high-temperature sterilization cycles without degradation of their structural properties, ensuring the longevity and safety of surgical instruments.

(3) Other Emerging Fields

In the sports and leisure sector, 6mm titanium rods can be used to manufacture components for golf club heads and connectors for mountaineering equipment. Their high strength and low density enhance the performance and user experience of sports equipment. In the marine engineering sector, 6mm titanium rods are used to manufacture components for underwater detection equipment and ocean monitoring buoys. Their excellent resistance to seawater corrosion ensures the long-term, stable operation of equipment in marine environments. As titanium application technologies continue to expand, the potential for 6mm titanium rods in fields such as new energy and environmental protection is gradually emerging, and they are expected to become a key material supporting technological innovation in these sectors.
