View Details6al 4v Titanium Plate
The high-strength Ti-6Al-4V alloy in plate form, engineered for critical structural applications demanding maximum load-bearing capacity and reliability under extreme conditions.
Product Overview
Bokang's 6al 4v Titanium Plate is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
6Al-4V titanium plate, conforming to Grade 5 specifications, is the preeminent high-strength titanium product for heavy-duty engineering. While sheet refers to thinner gauges, plate specifically denotes thicknesses typically starting at 6mm (0.25 inches) and extending beyond 100mm, representing the most robust form of this alpha-beta alloy.
Its primary function is to serve as the foundational material for machining large, load-critical aerospace components, defense systems, and high-performance industrial parts. The production of 6Al-4V plate involves stringent thermomechanical processing and heat treatment controls to guarantee through-thickness properties such as tensile strength (≥895 MPa), fracture toughness, and fatigue life. Unlike sheet, plate is often subjected to extensive non-destructive evaluation, including ultrasonic inspection, to ensure internal soundness for safety-critical applications.

Key Advantages of Bokang 6al 4v Titanium Plate
Discover why our titanium wire stands out in the industry
Exceptional Structural Depth Integrity
Guarantees uniform mechanical properties and a defect-free microstructure throughout the entire cross-section, which is paramount for components bearing through-thickness stresses.
Superior Machining Stock Form
Acts as the optimal starting blank for subtractive manufacturing of large, complex 3D parts like bulkheads and fittings, where the properties of a forging are not mandated by design.
Tailored Damage Tolerance
Can be supplied in Beta Annealed condition, which develops a lamellar microstructure offering enhanced fracture toughness and resistance to crack propagation for damage-tolerant designs.

Material Selection Guide
How to choose the right titanium wire for your application
1
Select Condition Based on Failure Mode
Choose Mill Annealed for maximum strength and ductility in fail-safe designs. Opt for Beta Annealed for fracture-critical applications where damage tolerance and crack arrest capability are primary.
2
Specify Ultrasonic Inspection Class
Define the acceptance criteria for internal quality. Class A (stringent) for primary aircraft structures, Class B (commercial) for general applications, or customer-specific requirements.
3
Account for Anisotropy in Design
Acknowledge that mechanical properties may vary slightly with orientation (longitudinal vs. transverse vs. short transverse). Design and analysis should reference property data from the appropriate direction.
4
Plan for Stress Relief During Machining
For complex parts machined from thick plate, incorporate intermediate stress relief annealing steps in the machining process plan to prevent distortion and ensure final dimensional stability.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
Multiple Vacuum Arc Remelting
Ti-6Al-4V electrode is melted and solidified multiple times in a VAR furnace to eliminate segregation and achieve chemical homogeneity in a large ingot.
→
Ingot Breakdown Forging
The ingot is heated and forged under a mega-ton press to refine the coarse cast grain structure and shape it into a slab suitable for rolling.
→
Precision Hot Rolling
The slab is rolled on a heavy plate mill with precise temperature and deformation control to achieve the target thickness and develop the required grain flow.
→
Controlled Cooling & Conditioning
The hot-rolled plate undergoes controlled air cooling or furnace cooling, followed by surface conditioning (scarfing, grinding) to prepare for heat treatment.
→
Thermal Processing (Annealing)
Plates are heat treated in large furnaces: either below the beta transus (Mill Anneal) or above it (Beta Anneal) to set the final microstructure and properties.
→
Final Processing & Certification
Plates are straightened, cut to size, ultrasonically inspected, and subjected to full mechanical and chemical testing to generate a mill certification report.
Frequently Asked Questions
Common questions about pure titanium wire
Mill Annealing occurs below the beta transus (~995°C), producing an equiaxed alpha-beta microstructure with optimal strength and ductility. Beta Annealing occurs above the transus, creating a coarse, lamellar (Widmanstätten) structure that sacrifices some ductility and strength for significantly improved fracture toughness and fatigue crack growth resistance.
Yes, it is readily weldable using GTAW or EBW. However, the weld fusion zone and HAZ become brittle martensitic alpha-prime. For critical structures, post-weld heat treatment (PWHT) is mandatory to temper this martensite and restore ductility. Strict atmospheric shielding is non-negotiable.
The base material cost per kilogram is similar. However, the absolute cost per piece is much higher due to the greater mass. Additionally, costs for premium conditions (Beta Annealed), extensive UT inspection, and procurement to tight aerospace specifications add significant premiums over commercial-grade sheet or bar.
Due to high setup and melting costs, minimum order weights can be substantial, often ranging from 500 kg to several metric tons for a specific melt. Smaller quantities are available from service centers as "split-plate" from larger inventory pieces.
Ti-6Al-4V is generally immune to stress corrosion cracking (SCC) in marine atmospheres and seawater, unlike high-strength steels and some aluminum alloys. This is a key advantage for its use in subsea and marine applications.
