TC4 Grade 5 Titanium Round Bar ASTM B348 High Strength For Industrial Machining

TC4 (Grade 5) titanium alloy is the most widely used α+β dual-phase titanium alloy in the industrial field, composed of titanium (Ti), aluminum (Al), and vanadium (V) as the main alloying elements. Our TC4 Grade 5 Titanium Alloy Rod strictly adheres to the requirements of ASTM B348 (Standard Specification for Titanium and Titanium Alloy Bars and Rods), ensuring consistent chemical composition, uniform metallographic structure, and stable performance. The product is processed through advanced vacuum arc smelting, precision forging, rolling, and heat treatment processes, with precise dimensional control and smooth surface finish, which can be directly used for various industrial machining operations such as turning, milling, drilling, and grinding.

Core Performance Advantages

• High Strength & Excellent Toughness: As a high-strength titanium alloy, TC4 Grade 5 has a tensile strength of 860MPa or more, combined with good impact toughness and fatigue resistance. It can withstand high mechanical loads and complex working stresses after machining, ensuring the durability and service life of the finished components in industrial equipment.
• ASTM B348 Standard Compliance: Strictly manufactured in accordance with ASTM B348 standard, the product meets the strict requirements of the standard for chemical composition, mechanical properties, dimensional accuracy, and surface quality. It is applicable to industrial fields with high quality standards, and can provide authoritative quality inspection reports to ensure product reliability.
• Superior Machinability: Optimized through special heat treatment processes, the titanium alloy rod has good machinability, which can effectively reduce tool wear during machining, improve cutting efficiency, and ensure the precision and surface finish of the machined parts. It is suitable for both conventional machining and precision CNC machining, adapting to various complex machining requirements.
• Excellent Corrosion Resistance: The surface of the TC4 Grade 5 titanium alloy rod forms a dense oxide film, which can resist corrosion from air, water, organic solvents, and most industrial media. It can maintain stable performance in harsh industrial environments such as humidity, corrosion, and high temperature, reducing maintenance costs and extending the service life of components.
• Lightweight & High Specific Strength: With a density of about 4.5g/cm³, it is much lighter than steel (7.85g/cm³) while maintaining high strength. The high specific strength (strength-to-weight ratio) can reduce the overall weight of industrial equipment, improve equipment operation efficiency, and save energy consumption.

Industrial Machining Adaptability

• Precision Machining: Suitable for CNC turning, milling, drilling, boring, and grinding, it can be processed into high-precision components such as shafts, gears, bolts, and connectors, which are widely used in precision machinery, instrumentation, and automation equipment.
• Heavy-Duty Machining: With high strength and wear resistance, it can withstand heavy-duty cutting and machining operations, and is applicable to the manufacturing of large-scale industrial equipment components, such as hydraulic cylinders, piston rods, and mechanical structural parts.
• Custom Machining: The product is available in various specifications, and can be customized according to customer machining requirements (such as diameter, length, and surface finish), ensuring that it can be perfectly matched with different machining processes and product designs.
