TI6AL4V Titanium Alloy Connecting Shaft

 

In a transmission system, the connecting shaft is the core component responsible for "transmitting torque and withstanding alternating loads." By selecting TI6AL4V Titanium Alloy Connecting Shaft (typically Gr5 TI6AL4V or high-strength TI-5Al-4.75Mo-4.75V-1Cr-1Fe), we are essentially addressing the irreconcilable trade-off between strength, weight, and service life found in traditional steel shaft systems. 

GR5 titanium alloy (also known as Ti-6Al-4V, International Grade 5) is currently the most widely used titanium alloy. Its tensile strength can reach 900–1200 MPa, approaching that of high-strength steel, yet its density is only about 4.43 g/cm³ (approximately 57% that of steel). Its specific strength (strength/density) ranks among the highest among metallic materials, making it the material of choice for weight reduction in aerospace structures.

1. Grade 5 Ti-6Al-4V Titanium-Aluminum-Vanadium Alloy (Mainstream Drive Shaft)

    The most versatile high-strength titanium alloy, used in 90% of drive shafts in the industry, offering a balance of strength, toughness, and machinability.

2. Grade 2 Pure Titanium Drive Shaft

    High corrosion resistance and low strength, suitable for lightweight drive shafts in seawater and acidic or alkaline corrosive environments.

3. Ti-5Al-5Mo-5V-3Cr High-Strength Titanium Alloy (High-End Heavy-Duty Custom Grade)

    Ultra-high tensile strength, serving as a substitute for certain alloy steels in military and high-end racing applications involving heavy-duty power transmission.

4. Ti-3Al-2.5V Thin-Walled Hollow Connecting Shaft

    High ductility and ease of deep processing for tubular materials, specifically designed for lightweight hollow drive shafts.

 

 

(1) Ultra-lightweight design

With a density of just 4.51 g/cm³, compared to 7.85 g/cm³ for 40Cr alloy steel, the weight is reduced by more than 40% for parts of the same structural dimensions;

(2) Exceptional mechanical properties

Grade 5 titanium alloy has a tensile strength of ≥900 MPa and a yield strength of ≥830 MPa, comparable to medium- and high-strength structural steels;

(3) Superior All-Weather Corrosion Resistance 

With a naturally formed passivation layer, it resists corrosion from seawater, salt spray, acidic and alkaline solutions, and humid, high-salinity environments, and is completely rust-free;

(4) Excellent High- and Low-Temperature Stability

Low-temperature performance: No embrittlement or loss of toughness in ultra-low-temperature environments down to -196°C;

High-temperature stability: No sudden drop in mechanical properties or softening and deformation during long-term continuous operation at temperatures up to 300°C;

No jamming due to thermal expansion and contraction in alternating hot and cold conditions; transmission clearance remains stable over the long term.

(5) Types of available surface treatment processes

Anodizing: Wear- and scratch-resistant, color-coded for different specifications, and enhanced surface hardness;

Mirror Polishing: Low friction, dust-resistant, and designed for precision instruments;

Micro-Arc Oxidation (MAO): Ultra-high surface hardness, suitable for heavy-duty, high-speed friction applications;

Natural Pickling and Passivation: General-purpose industrial finish, a low-cost, corrosion-resistant standard option;

(6) Our Product Features

One-piece forged construction: Solid shafts, hollow shafts, flanged shafts, splined shafts, stepped shafts, and universal joint drive shafts can all be forged as a single piece, minimizing assembly gaps.
