View DetailsTitanium Barstock
Solid, long titanium products with a round, square, or rectangular cross-section, serving as the primary raw material for machining forgings, and fabricating high-strength components.
Product Overview
Bokang's Titanium Barstock is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
Titanium barstock refers to a versatile family of solid, long products with a consistent cross-sectional shape—most commonly round, but also square, rectangular, and hexagonal. It is produced through hot rolling, forging, or extrusion of titanium ingots and is supplied in straight lengths or coils (for smaller diameters). Barstock is the foundational material form for a vast range of manufacturing processes, particularly where significant material removal is required, such as CNC machining, screw machining, and the creation of custom fasteners.
Available in all commercial titanium grades (CP Grades 1-4, Ti-6Al-4V, Ti-6Al-4V ELI, Ti-3Al-2.5V, etc.), barstock's properties are defined by its alloy, heat treatment condition (annealed, solution treated and aged), and surface finish (hot-rolled, turned, ground, polished). Key selection criteria include diameter (or width/thickness), tolerance, straightness, and surface quality. It is the go-to material for producing shafts, valves, fittings, biomedical implants, aerospace actuators, and any component where the integrity and properties of a solid section are required.

Material Selection Guide
How to choose the right titanium wire for your application
1
Determine the Final Part's Load Path & Critical Dimensions
Select a bar diameter that provides sufficient stock for machining to the final dimensions while ensuring the part's critical stress-bearing cross-section has the desired grain orientation relative to loads.
2
Specify Surface Condition Based on Manufacturing Steps
Choose hot-rolled (HR) bar for parts where the entire surface will be machined. Specify turned, ground, or polished bar if the OD will be a finished surface or for better tool life in automated screw machines.
3
Choose Alloy and Condition for Machinability & Performance
For complex machining, CP titanium (Grade 2) offers the best machinability. For high-strength parts, use annealed Ti-6Al-4V. For maximum strength after machining, specify solution treated and aged (STA) condition, but account for its lower machinability.
4
Optimize Purchase Quantity & Form
Balance cost between buying full random lengths (cheaper per kg) and pre-cut blanks (reduces in-house waste). For high-volume production, consider coil stock for small diameters to enable automated feeding.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Ingot Conditioning & Heating
A titanium ingot, previously melted to the required grade, is surface conditioned (ground) and heated uniformly in a furnace to its forging/rolling temperature.
→
Primary Forging or Rolling
The hot ingot is forged on a press to break down the cast structure and create a bloom, which is then rolled on a bar mill to reduce its cross-section and elongate it.
→
Multi-Standard Rolling & Sizing
The bar passes through a series of rolling stands with shaped grooves to achieve its final cross-sectional shape (round, square, etc.) and approximate diameter.
→
Heat Treatment (Annealing)
The long bar is coiled or laid out and annealed in a furnace to relieve stresses from rolling and to set the desired mechanical properties (e.g., annealed condition).
→
Descaling, Straightening & Cutting
The scaled surface is removed by pickling or shot blasting. The bar is straightened and cut to standard mill lengths (e.g., 10-20 feet).
→
Final Finishing, Inspection & Bundling
For precision bars, additional turning or centerless grinding is performed. Bars are inspected for dimensions, surface defects, and marked with grade and heat number before bundling for shipment.
Frequently Asked Questions
Common questions about pure titanium wire
The distinction is primarily one of size and intended use. Billet refers to a larger, semi-finished product (typically over 4-6 inches / 100-150mm in diameter or square) that is intended to be further processed, usually by forging or re-rolling into smaller bar, rod, or wire. Barstock is a finished product in smaller diameters, ready for direct use in machining or fabrication. The same alloy can be purchased as either, depending on the customer's needs.
Centerless grinding is a secondary, precision machining operation that removes a thin layer of material from the entire bar length. This achieves three things: extremely tight diameter tolerances (often within ±0.025mm), a superior surface finish (smooth, no scale), and improved straightness. This precision reduces setup time and tool wear in the customer's CNC machines and is essential for parts where the bar's outer diameter is a finished surface. The added processing cost justifies the higher price.
During rolling, the metal's grains elongate in the direction of rolling (longitudinal direction). This creates directional properties: strength and ductility are typically higher parallel to the bar length (with the grain flow) than across it (transverse). For a critical part like an aircraft landing gear axle, the bar is oriented so the primary tensile loads align with the longitudinal grain flow, maximizing fatigue life and fracture toughness.
For standard barstock, the microstructure (e.g., equiaxed alpha-beta for Ti-6Al-4V) is a result of the mill's standard thermomechanical processing. For specialized applications (e.g., aerospace forgings requiring a bi-modal structure), you would purchase billet or forging stock, not finished bar. The mill can sometimes provide bar with a certified microstructure per a specific AMS requirement, but this is a premium product.
Store bars horizontally on sturdy, level racks to prevent bending. Keep them dry and free from contamination by other metals (especially iron and steel) to prevent galvanic corrosion or iron pickup. For critical applications, protect the ends from damage that could introduce stress concentrators. Identify and segregate bars by alloy grade and heat number to maintain traceability.
