3- Titanium and Aluminum: a Detailed Comparison Between the Two Popular Metal Choices
Material Properties Differences between Titanium and Aluminum
Element Composition
The difference in the elemental composition of Titanium and aluminum leads to specific characteristics they show. This table provides the elemental composition of both:
| Titanium | Aluminum |
| Nitrogen Iron Hydrogen Oxygen Carbon Iron Nickel | These elements include the following: Zirconium Zinc Silicon Chromium Magnesium Titanium Iron Manganese Copper |
Corrosion Resistance
Aluminum forms a thin protective coating which helps to make it non-reactive material. This layer makes aluminum good for various applications. More biocompatible and other specific features make it more corrosion-resistant when compared to aluminum.
Durability
Aluminum and titanium are resilient metals that work well without requiring many repairs or upkeep. You can use them for an extended time. Aluminum becomes weak when applying high temperatures and has a lower thermal expansion rate.
A low expansion rate is a cause of high rigidity and resistance for fatigue fractures. So you can use titanium for rigorous conditions and applications that need high strength and toughness.
Weight
Weight is a main factor to consider while selecting the material. Heavy and durable material such as titanium is good for intricate parts manufacturing. Light, cost-effective material such as aluminum is good for low-budget projects but not guarantee long-lasting products.
Although both metals exhibit the same characteristics in some ways and are lightweight materials, they also have some variations and limitations, so you must know where they can fit according to their properties and which material will be best and cost-effective for your parts fabrication.
Machinability
Machinability means how a material responds to stress during turning, stamping, and milling operations. So you can set the machining technique for manufacturing aluminum and titanium parts. CNC turning and milling are utilized processes for quick and fast parts fabrication.
You may switch to other metals such as titanium or other metals for intricate geometries, highly specific parts, and according to the customer’s requirements. So check material machinability, scrape rate, formability, and other features according to your part demand.
Weldability
You can easily weld aluminum and titanium. Welding is the material capacity to unite. Titanium is not easy to weld; therefore, it requires skilled and trained personnel to handle the process. In comparison, aluminum can be easily welded and used for many applications. You can use aluminum for its easy-to-weld ability.
Strength Differences Between Titanium and Aluminum
Yield Strength & Tensile Strength
Pure titanium has low yield strength, and you can not rely on it for aircraft and any other industry which need good yield strength.
Titanium has low yield and tensile strength, while aluminum has good yield strength, so it is a more used material for many applications due to good tensile and yield strength. Titanium ranges of tensile strength are 230 Mpa. It ranges differently as its condition changes.
Ability to Form
Formability
Aluminum is easier to fabricate, and you can shape it easily in your desired products. Titanium density is, and it can not be easy to manufacture. Aluminum is used where formability is a key factor. Titanium also has good formability but cannot be easy to fabricate, so you must choose a professional and verified manufacturing company for titanium parts manufacturing.
Melting Point
It is the temperature at which a metal changes into a liquid. Titanium has a high melting point, making it a suitable refractory material. It has a melting point of 660.37 ᵒC. You can use titanium for those projects which have requirements of high heat resistance.
Aluminum has a low melting point, so make sure before it can fulfill the requirement of environmental changes for your production.
Appearance and Touch
Color and Hardness
Color difference makes it easy to recognize metal and select any material for your project. The aluminum color is silver-white, and its hardness shows how easily it can be scratched, etched, or deformed. You need to know is titanium stronger than aluminum. Some aluminum alloys have high hardness, such as AAtemper T7, AA 6082 temper, etc.
Conductivity Differences Between Titanium and Aluminum
Thermal and Electrical Conductivity
Heat transformation is called thermal conductivity, and a good radiator has high thermal conductivity. Aluminum conductivity is 1460 BTU-in/hr-ft²-°F (210 W/m-K) and is a high conductivity. You may not find titanium a good conductor of electricity. You see the use of aluminum for most applications, such as heat exchangers and many others.
Pricing and Options
You may find a great price difference when comparing titanium vs. aluminum. Aluminum rod is less expensive and easy to fabricate, so most manufacturers choose them for prototyping and cnc machining.
Professional requirements for bending and welding make titanium more intricate to choose from. It also increases its overall cost, while aluminum is the best and most cost-effective choice.

Between Titanium vs. Aluminum: How Do You Choose the Best One?
Various factors influence the decision made regarding an application. You may need to consider the following characteristics in this regard:
Cost
Cost is a critical factor to consider before starting any project. Therefore aluminum is cheap for CNC machining, but you must recognize the value and durability of other materials, such as titanium. Although more costly than aluminum, it adds value to your parts and promises long life and durable parts.
So the cost of titanium vs. aluminum affects the overall product consumption. If you have a good budget, titanium is a good choice for machining.
Applications
You may need to answer several questions while choosing the material best for your project. These demand specifications about the environment you need to employ your product. What type of project do you need to use the material, or what is your required strength? Do you require a cheap metal or costly metal?
Both metals are useful in various fields, such as titanium is good for medical, aerospace, and fixtures and has good corrosion resistance and poor electrical conductivity. In comparison, aluminum is considered good for plastic molding and tooling. It is also an ideal material for bicycle frames and vehicle frames.
Machinability
Check if your selected material is easy to machine or hard to machine for cnc machining or prototyping. Easy-to-make metal requires less time for production, while hard materials need more time for fabrication. So aluminum is good to use for quick and fast projects, while you can select titanium for long-term projects and durable parts.
Machining Consumption
When comparing titanium aluminum alloy and intricate design geometric considerations, machine consumption is important. Waste produced in the manufacturing process limits your method, no matter your chosen material.
In this case, your preference should be a cheap aluminum rather than titanium, as milling away machining wastage needs to be addressed. Therefore manufacturing companies choose aluminum for bulk production and prototyping to reduce the overall cost of a project, and for small projects, they select titanium.
Aesthetic Requirements
Aesthetic requirements incorporate your parts manufacturing, and some finishing methods are applied, such as wire brushing, sandblasting, and coating. The aluminum color is silvery white and does not require a protective layer.
However, some electrochemical and chemical surface finishes can be used if pure aluminum needs an additional protective layer. Titanium has a silver color, and it gives a dark grey effect during exposure to light.
