Introduction
Grade 5 titanium, commonly designated as Ti-6Al-4V, is one of the most prevalent and versatile titanium alloys in global industrial applications. The provided source materials offer detailed technical specifications, available dimensions, and key characteristics of this alloy, primarily focusing on sheet and plate forms. This article synthesises this information to provide a factual overview for professionals and enthusiasts interested in sourcing and utilising Grade 5 titanium. It is important to note that the sources do not contain information regarding free samples, promotional offers, or consumer-focused trial programmes for this industrial material. The data is strictly technical and commercial in nature, detailing material properties, stock availability, and procurement processes.
Technical Composition and Properties
Grade 5 titanium (Ti-6Al-4V) is an alpha-beta titanium alloy. According to the sources, its chemical composition consists of approximately 90% titanium, 6% aluminium, 4% vanadium, with maximum limits of 0.25% iron and 0.2% oxygen. The addition of aluminium and vanadium enhances the hardness of the material within the alloy matrix, thereby improving its physical and mechanical properties.
The sources highlight several key characteristics that make this alloy highly sought after: * Excellent Strength: It offers a high strength-to-weight ratio, which is critical for aerospace and other high-performance applications. * Low Modulus of Elasticity: This property contributes to its performance in applications requiring flexibility and resilience. * High Corrosion Resistance: Titanium's natural resistance to corrosion ensures long-lasting performance in various environments. * Good Weldability and Heat Treatability: These properties make it suitable for complex manufacturing processes and allow for post-fabrication property adjustments.
Available Dimensions and Forms
The provided data lists extensive size ranges for Grade 5 titanium sheets and plates, with specific dimensions available from suppliers. The sources indicate that sheets and plates are typically available in standard dimensions of 48 inches by 120 inches (1219 mm x 3048 mm), though some suppliers offer wider plates.
Sheet Thickness Ranges
Sources [1] and [2] specify that Grade 5 titanium sheet is available in a broad thickness range: * Thin Sheets: From 0.012 inches (0.30 mm) up to 0.125 inches (3.18 mm). Specific examples include 0.028" (0.71 mm), 1/32" (0.79 mm), 0.035" (0.89 mm), 0.05" (1.27 mm), 1/16" (1.59 mm), 1/8" (3.18 mm), and 3/16" (4.80 mm). * Thicker Sheets: Extending up to 1/4" (6.30 mm), 3/8" (9.50 mm), and 1/2" (12.70 mm).
Plate Thickness Ranges
Plate stock is generally available in thicker dimensions: * Standard Plates: From 0.250 inches (6.35 mm) to 4.000 inches (101.6 mm). Specific examples include 5/8" (15.90 mm), 3/4" (19.00 mm), 7/8" (22.20 mm), 1" (25.40 mm), 1 1/4" (31.80 mm), 1 1/2" (38.10 mm), 2" (50.80 mm), 2 1/4" (57.20 mm), 2 1/2" (63.50 mm), 3" (76.20 mm), 3 1/2" (88.90 mm), and 4" (101.6 mm). * Heavy Plates: For specialised applications, some suppliers offer plates from 6 mm to 25.4 mm in thickness, with widths up to 3500 mm. A separate category for "Grade 2 Titanium Heavy plate" is mentioned, with thicknesses from 25.4 mm to 100 mm.
Industry Applications
The sources consistently identify several key sectors where Grade 5 titanium is indispensable due to its unique properties.
- Aerospace: This is cited as the most common market for Ti-6Al-4V. Applications include compressor blades, discs, and rings for jet engines; airframe components; pressure vessels; rocket engine cases; and helicopter rotor hubs. Its high strength-to-weight ratio is paramount here.
- Military and High-Performance Automotive: The alloy's ability to withstand high temperatures and extreme conditions makes it suitable for military applications and high-performance automotive components.
- Marine and Shipbuilding: Titanium's exceptional corrosion resistance is ideal for marine engineering, shipbuilding components, and equipment exposed to saltwater environments.
- Medical: While the sources focus on Grade 5, they note that CP (Commercially Pure) Grade 2 titanium is preferred for medical implants due to its biocompatibility. However, Grade 5's strength is also utilised in certain medical devices and surgical tools.
- Chemical Processing: The corrosion resistance is valuable for equipment in chemical plants.
- Other Industries: The sources mention growing prospects in the automotive industry and for high-end sports equipment. Grade 2 titanium is also used for heat exchangers, pressure vessels, and nuclear energy equipment.
Sourcing and Procurement
The provided materials are from commercial suppliers, indicating that Grade 5 titanium sheet and plate are primarily sourced through direct industrial procurement rather than consumer sampling programmes.
- Availability: Suppliers like Chalco, Upmet, and Titanium Joe (as referenced in the source URLs) list Grade 5 titanium as a core product. Sources state that sheets and plates are "in stock and ready for fast shipping."
- Procurement Process: The process typically involves contacting the supplier for a quote. For instance, Upmet advises potential customers to "call us for a quote on your next material requirement." Titanium Joe's site suggests contacting them for specific product inquiries. Some suppliers, like Upmet, also provide an email address ([email protected]) for sourcing groups if standard inventory does not meet requirements.
- Standards and Specifications: The alloy complies with multiple international and industry standards, including ASTM B265, ASME SB-265, AMS 4902, AMS-T-9046, MIL-T-9046, DIN 65039, and ASTM F1472. It also meets specific aerospace material specifications (AMS 4911, 4928, 4967, 6931).
- Pricing: One source mentions "competitive pricing" and helping customers "save on materials without compromising quality," indicating that pricing is a factor in procurement, though specific costs are not provided.
