Overview of Titanium Alpha Beta Alloy

Titanium is available in two types: pure titanium and titanium alloy. Alpha titanium, beta titanium, and alpha-beta titanium are three phase types of titanium alloys. Among them, alpha beta titanium alloy is widely used.

This article can help you understand the Alpha Beta Titanium Alloy.

What is Titanium Alpha Beta Alloy?

Titanium alpha beta alloy is a duplex titanium alloy that includes both α and β phases, that is, it has both a dense hexagonal structure and a body-centered cubic structure. This gives it a good balance of all aspects of performance.

Performance Characteristics of Titanium Alpha Beta Alloy

2.1 The comprehensive mechanical properties are very good. The strength, toughness, and plasticity of titaniumα-βalloy are excellent.

2.2 Good processing performance. Titanium Alpha Beta Alloy has good welding, stamping and forging properties, is easy to machine, and can usually be made into various forms such as titanium plates, titanium rods, titanium wires, and titanium fasteners.

2.3 Strong heat treatment ability. After treatment with the “solution age” step, the strength of Titanium Alpha Beta Alloy can be increased by at least 50%.

2.4 It can work for a long time at an ambient temperature of 300-400°C.

Which Titanium Alloy Types Belong to Titanium Alpha Beta Alloy?

The most common titanium alpha beta alloy is TC4 (Ti-6Al-4V) titanium alloy. The content of aluminum (Al) is about 5.5%-6.8%, and the content of vanadium (V) is about 3.5%-4.5%. In addition, it contains small amounts of iron (Fe), oxygen (O), carbon (C), nitrogen (N), hydrogen (H) and other impurities.

The alpha and beta stabilizers in TC4 titanium alloy are aluminum, vanadium, iron and other elements. Aluminum (Al) is an alpha stable element, vanadium (V) and iron (Fe) are beta stable elements. It is these duplex stable elements that make TC4 titanium alloy widely used for its excellent properties.

In addition, TC6 (Ti-8Al-1Mo-1V), TC11 (Ti-6Al-2Sn-4Zr-2Mo), TC16 (Ti-6Al-6V-2Sn), and TC1 (Ti-4Al-2V) are also titanium alpha beta alloys.

Applications of Titanium Alpha-Beta Alloys

4.1 Sports equipment

Bicycle frames, golf club heads, fishing rod guides, trekking pole holders. Titanium tubes, titanium rods, titanium wires, etc. made of TC4 or TC2 alloy are usually used.

4.2 High-end consumer goods

Outdoor knife handle/blade substrate, watch case/strap, eyeglass frame, etc. Titanium plates, titanium wires, etc. made of Titanium alpha beta alloy are generally used.

4.3 Everyday consumer goods

Kitchenware/tableware, mobile phone middle frames, computer hinges, etc. are usually made of titanium plates, titanium wires, etc. made of Titanium alpha beta alloy.

4.4 Medical aspects

Orthopedic implants: artificial joints, fracture fixation plates. These are typically used in titanium alpha beta alloy products such as titanium plates, titanium rods, and titanium wires.

Dental: dental implant abutments, dental implants, etc.

Surgical instruments, etc.

4.5 Aerospace aspects

Fasteners, engine components, landing gear components, etc. used in aircraft are typically manufactured using Titanium Alpha Beta Alloy, and products such as titanium alloy plates, titanium alloy fasteners, and titanium alloy wires made of TC4 alloy are commonly utilized.

4.6 Chemical field

Titanium Alpha Beta Alloy is commonly used in the manufacture of marine components, marine pipelines, heat exchangers, etc.

Comparison of Titanium Alpha-Beta Alloys and Titanium Alpha Alloys and Titanium Beta Alloys

Characteristics	Alpha titanium	Beta titanium	Alpha-Beta titanium
Crystal structure	Secretly arrange the six directions α prime ministers	The body-heart cube β phase	α and β are mixed
Alloy stabilizing elements	α Stabilizing elements: Al, O, N, C	β Stabilizing elements: Mo, V, Nb, Cr, etc	Contains both α stable elements (Al) and β stable elements (Mo, V, Mn, etc.)
Common grades	Industrial pure titanium（TA1、TA2、TA3）、TA6、TA7	TB2、TB3、TB5（Ti15333）、TB6	TC4（Ti-6Al-4V）、TC1、TC2、TC11
Strength, plastic properties	Medium strength, excellent plasticity	High strength and good Plasticity is better	The strength is between α and β, and the plasticity is not bad
Heat resistance	Works at 300-500°C	less than or equal to 200°C	300-400℃
Corrosion resistance	Corrosion resistance is the best	Good corrosion resistance	Corrosion resistance is not as good as beta titanium
Processability	Good hot processing performance and average cold working performance	Excellent cold working performance	The overall performance is relatively balanced
Heat treatment properties	Solution annealing treatment can be carried out, but quenching and aging are not good	Solution + aging treatment is fine	Annealing, solution and aging can all be handled flexibly
