Titanium Alloy Forged Disc

A titanium alloy forged disc is a high-performance circular component and it manufactured from premium titanium alloys by precision forging. This process refines the internal grain structure, delivering superior strength, light weight, and corrosion resistance for critical applications.

Titanium alloy forged discs are core components for aerospace engines, energy turbines, and high-end industrial equipment. Their manufacturing process centers on strict temperature control, precise deformation management, and microstructure optimization, ensuring high strength, fatigue resistance, and dimensional stability.

• The forging equipment mainly includes one set of 100mt and one set of 50mt electro-hydraulic free forging hammers.
• It is supported by 2 electric resistance furnaces, 2 annealing furnaces and 1 set of manipulator.
• The monthly production capacity reaches 60 metric tons.
• Equipped with sufficient production facilities, we can promptly process customer orders.
• We cooperate with professional logistics companies at the port.
• We provide overseas customers with multiple delivery options, including sea freight, land-sea combined transport and air freight.
• We are able to offer customers competitive prices and reliable after-sales service.
• Our company was awarded EN ISO 9001:2015 and EN 9100:2018 certifications for European aerospace products by Bureau Veritas (BV) France in 2025.
• We have established an in-house testing center.The center is equipped with more than 10 advanced testing instruments.We adopt a comprehensive quality system and rigorous inspection methods.

1. Material Selection & Billet Preparation

Use triple vacuum arc remelting certified titanium alloy ingots; cut into cylindrical billets, conduct surface treatment and ultrasonic testing to ensure qualification.

2. Preheating

Heat titanium alloys in electric resistance or vacuum furnaces; temperature varies by alloy , holding time 1–2 hours per 100 mm of billet thickness.

3. Forging

Two main methods: Open-Die Forging and Closed-Die Forging .

4. Post-Forging Heat Treatment

Solution annealing + aging; vacuum heat treatment for high-performance aerospace discs.

5. CNC Machining

Rough machining; finish machining with 5-axis CNC machines.

6. Surface Treatment

Shot peening, anodizing, polishing.

7. Quality Inspection

100% inspection including dimensional verification, mechanical testing, microstructure analysis, and repeated NDT.
