View Details12mm Titanium Rod
A robust 12mm diameter titanium rod, offering enhanced strength and stiffness over smaller diameters for demanding structural and mechanical applications.
Product Overview
Bokang's 12mm Titanium Rod is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
The 12mm titanium rod represents a step up in diameter and mechanical capability from the more common 10mm size, providing approximately 44% greater cross-sectional area and a corresponding increase in load-bearing capacity. This makes it suitable for applications where higher bending moments, torsional loads, or tensile forces are anticipated, but where a larger, heavier bar would be excessive. The 12mm diameter is a standard metric size, aligning with common bearing bores, fastener sizes (M12), and hydraulic cylinder rod diameters.
This rod is frequently utilized in the construction of more substantial frameworks, as axles for heavier equipment, and as stock for machining larger custom fasteners or hydraulic components. Like its smaller counterparts, it is available in all standard titanium grades and conditions. The increased diameter makes hot-rolled and turned finishes more common for cost-effectiveness, though precision ground 12mm rod is available for applications requiring tight tolerances on the outer diameter. Its versatility and strength make it a preferred choice for industrial, automotive, and marine applications where reliability under significant load is paramount.

Key Advantages of Bokang 12mm Titanium Rod
Discover why our titanium wire stands out in the industry
Significantly Higher Bending and Torsional Rigidity
The moment of inertia increases with the fourth power of diameter. A 12mm rod is over twice as stiff in bending as a 10mm rod, drastically reducing deflection under load.
Robust Stock for Heavy-Duty Fasteners
Ideal as the starting material for machining large custom bolts, pins, and studs (e.g., M12 size) that require the strength and corrosion resistance of titanium in structural connections.
Improved Vibration Damping Characteristics
The larger mass and cross-section provide better inherent damping of vibrations compared to smaller diameter rods, beneficial in rotating shafts and structural supports.

Material Selection Guide
How to choose the right titanium wire for your application
1
Calculate Critical Loads for Buckling and Bending
For long, slender 12mm rods under compressive load, calculate the Euler buckling load. For bending, use the section modulus (Z=170 mm³) to find maximum stress. Ensure the selected grade's yield strength provides an adequate safety margin.
2
Select Condition Based on Machining vs. As-Used Requirements
If the entire surface will be machined, hot-rolled rod is most economical. If the rod will be used as-is (e.g., as a shaft or pivot), specify cold-drawn or ground rod for better surface finish and dimensional consistency.
3
Consider Threading and Connection Design
12mm is a standard thread size (M12). Design for sufficient thread engagement length (typically 1.5x diameter). For Grade 5, ensure threads are cut or rolled in the annealed condition to prevent cracking.
4
Evaluate Surface Treatments for Wear or Corrosion
For sliding contact applications, consider specifying hard-anodized or PVD-coated rod. For maximum corrosion resistance in specific media, select a palladium-enhanced grade (Grade 7) from the outset rather than relying on coatings.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Billet Heating and Rough Rolling
A titanium alloy billet is heated and passed through initial rolling stands to reduce it to a "roughing" size larger than 12mm.
→
Intermediate Rolling and Sizing
The bar passes through intermediate stands that bring it closer to the final 12mm dimension while maintaining a round cross-section.
→
Finishing Roll Pass and Controlled Cooling
A final pass through a precision finishing stand sets the diameter to approximately 12.5mm (allowing for scale). The bar is then cooled on a cooling bed.
→
Pickling and Scale Removal
The cooled bar, now covered in thick oxide scale, is pickled in acid to reveal a clean, metallic surface suitable for further processing or as a hot-rolled product.
→
Cold Drawing (Optional for Precision)
For cold-drawn product, the pickled bar is drawn through a die to achieve the exact 12.0mm diameter, a bright surface finish, and improved mechanical properties.
→
Straightening, Cutting, and Final Inspection
The rod is straightened, cut to ordered lengths, and inspected for diameter, straightness, and surface quality before being bundled and tagged.
Frequently Asked Questions
Common questions about pure titanium wire
For a standard slip fit (H7/g6 or H7/h8 tolerance), the hole should be slightly larger than the rod. For a 12mm h8 rod (max diameter 12.027mm), a hole drilled and reamed to 12.0mm to 12.027mm would work. In practice, drilling an 11.8mm or 12.0mm hole and then reaming to 12.0mm or 12.02mm is common. Always consult engineering tolerance tables for the specific class of fit required for your application.
Yes, but it requires care. Full penetration welds are achievable with proper joint preparation (beveling) and technique. However, welding significantly reduces the fatigue strength in the heat-affected zone (HAZ). For critical load-bearing structures, it is often better to machine the part from a single piece or use a mechanical connection (like a threaded joint or pin) to avoid the property degradation associated with welding.
It could be for a lightweight or non-standard application, but it is generally undersized for a main front or rear axle on most street or off-road motorcycles, which typically use 15mm, 17mm, or 20mm axles. A 12mm Grade 5 titanium axle might be used on a very lightweight bicycle or a small component within the suspension. Never substitute a critical safety component like an axle without thorough engineering analysis.
Machining titanium costs significantly more. Factors include: slower cutting speeds (to manage heat), more frequent tool changes (due to abrasiveness and work hardening), specialized tooling (carbide, high-pressure coolant), and higher power consumption. As a rough estimate, machining titanium can cost 2-4 times more per hour of machine time than machining mild steel, and the raw material is also 5-10 times more expensive per kilogram.
The most accessible method is using a high-quality bi-metal hacksaw with a 24-32 TPI blade and cutting fluid. Clamp the rod firmly near the cut. A portable bandsaw with a metal-cutting blade is faster. For the cleanest cut, an abrasive cut-off wheel on an angle grinder or chop saw is very effective—wear full face protection due to sparks. Always secure the rod to prevent rotation or binding.
