Ti-6AL-4V Titanium Alloy CNC Machining Parts

 

Ti-6AL-4V Titanium alloy is the most popular and widely used alloy in titanium CNC machining field, having widly applications that need high strength and lightweight, also has high corrosion resistance. 

In another word, Titanium alloy Ti-6Al-4V is a multi-functional high-tech metal, having the advantages of Low density, Excellent force strength, are widely used in aviation, aerospace, chemical engineering, petroleum, power, medical care, construction, sports goods and other fields.

It is hailed as "space metal", "ocean metal", "smart metal", "strategic metal" and "metal of the future".

 

 

 

 

1. Material definition

 

Composition system: Ti-6Al-4V (α+β duplex titanium alloy), aluminum (5.5%-6.75%), vanadium (3.5%-4.5%)

Execution standard

International standards: ASTM B348 (bars), AMS 4911 (Aerospace forgings)

 

2. Key performance indicators

 

The processing significance of typical parameters of performance categories：

1) High-strength structural components with tensile strength of 895-930 MPa (annealed state) require optimized cutting parameters

2) The elastic modulus is 110 GPa. It is prone to vibration during processing, so the rigidity of the fixture needs to be enhanced

3) The thermal conductivity is 6.7 W/(m·K) at 20℃. It has poor heat dissipation and requires forced cooling to avoid thermal damage

4) When choosing cutting tools with a hardness of HRC 32-36 (aged state), both wear resistance and toughness should be taken into account

 

 

A. Five-axis linkage processing of aerospace shuttle engine blades, surface accuracy ≤0.02mm

B. Mirror polishing of artificial joint prostheses for medical devices (Ra≤0.1μm)

C. Thin-walled processing of racing connecting rods in the automotive industry (wall thickness 1.5±0.05mm)

D. Large-diameter thread processing for Marine engineering deep-sea submersible pressure-resistant shells (M100×4, precision 6H)

E. Micro-hole processing of 3C electronic mobile phone frames (hole diameter Φ0.3mm, depth-to-diameter ratio 5:1)

 

Heat treatment process: 

Stress relief annealing: 700-800℃×1-2h/ air cooling (eliminating 90% residual stress)

Solution aging

Solution: 950℃×1 hour/water quenching

Aging: 540℃×4 hours/air cooling (strength increased to 1100MPa)

 

Ti-6AL-4V Titanium alloy CNC machining parts, with its three major advantages of being lightweight, high-strength, corrosion-resistant and biocompatible, is quietly changing our lives from aerospace to medical implants, from high-end mobile phones to sports equipment.
