Aluminum vs Titanium: Difference and Comparison

Lightweight and strength are the primary characteristics of a powerful combination of materials. Aluminium and titanium are the two which satisfy the above statement. Resistance to corrosion and tolerance to heat are excellent features of the materials. The reason for the light weight of the materials is different from one other.

Key Takeaways

  1. Aluminium is lightweight, more abundant, and less expensive than titanium.
  2. Titanium is stronger, more durable, and more corrosion-resistant than aluminium.
  3. Both metals have versatile applications in the aerospace, automotive, and construction industries.

Aluminium vs Titanium

The difference between Aluminum and Titanium is the mixture of copper in the alloy. The aluminium alloy has less amount of copper, and the titanium alloy has more amount of copper. Aluminium is less complex when compared to titanium. Sometimes more effective parts are obliged in critical situations, for that titanium will make good sense. Aluminium is pretty cost-efficient, while titanium is expensive.

Aluminum vs Titanium

Al is the symbol of aluminium. Aluminum is a chemical element used as a raw material for many products. The atomic number of aluminium is 13. The word aluminium comes from American and Canadian English. When compared to other metals, aluminium has a lower density than almost one-third of steel. While exposed to the air, aluminium is a protector that makes a layer of oxide around the products since it has a strong affinity towards oxygen.

Ti is the symbol of titanium. Titanium is a chemical element present in the 4th period, d-block with the atomic number 22. In 1791, the clergyman and amateur geologist William Gregor discovered titanium. Pure titanium was discovered by Anton Eduard van Arkel and Jan Hendrik de Boer using iodiate process in 1925. Martin Heinrich Klaproth is the one who named the metal titanium. In Daltons, the atomic weight of titanium is 47.867. The outer appearance of titanium is silver-grey-white metallic.

What is Aluminum?

Aluminum is a chemical element, and the historian Herodotus made the first written proof of aluminium’s presence on Earth. The first statue made of aluminium was placed in London, and the name of the statue is The Statue of Anteros. Silver-grey metallic is the outer appearance of aluminium. It is present in the third period and p block in the chemical table with the atomic number 13. Aluminum has a great ability to reflect light which resembles silver in its color.

The melting point of aluminium is 660 degrees Celsius, and 2470 degrees Celsius is aluminium’s boiling point. Aluminum is the twelfth most common element in the universe. Ductile, soft, and non-magnetic are some characteristics of aluminium. Aluminum has one stable isotope, which is 27Al. In the boron group, aluminium is the weakest element when compared to other metals in that group. In radio dating, the 27Al isotope is used as a radioactivity element.

The Danish physicist who announced the discovery the aluminium in 1825. Aluminum is primarily found in the outer layer of the rocks due to its affinity towards oxygen, which makes the oxide layer. After oxygen and silicon, aluminium is the third most abundant element in the universe. In 1856, aluminium was used in industrial production by a French chemist. For aviation in both World wars, aluminium is a strategic metal and a crucial resource.


What is Titanium?

Titanium is a high-strength metal that is resistant to corrosion and tolerant to heat. Titanium has a low density with a silver color look. Only in countable minerals the deposits of titanium are founded, especially in rutile and ilmenite. It is present in Earth’s crust and in the layer of the lithosphere. All living things, water bodies, and soil have the presence of titanium. The process called Kroll and Hunter is the primary process used in the extraction of titanium from the Earth’s crust.

Titanium is one of the most popular metals on Earth. Titanium dioxide is a photocatalyst used to produce white pigments. In the production of polypropylene, titanium trichloride is used. Titanium tetrachloride is a vital component in the production of smoke screens. The melting point of titanium is 1668 °C, and the boiling point of titanium is 3287 °C. The atomic radius of titanium is 147 pm. It can strongly alloy with various metals like iron, vanadium, and molybdenum.

The titanium alloy is used to produce jet engines and space crafts. It is also used in various fields for various purposes. It is used in industries, agriculture, medical and sports applications. The corrosion resistance and strength-to-density ratio is the highest property in titanium when compared to other metals. It has a less dense but strong nature in unalloyed conditions. Titanium has five naturally occurring isotopes with two allotrophic forms.


Main Differences Between Aluminum and Titanium

  1. The third most abundant element on the earth is aluminium, and the ninth most abundant element on the earth is titanium.
  2. Aluminum is a non-magnetic metal, whereas titanium is a paramagnetic metal.
  3. In a chemical table, aluminium is considered a metal, and titanium is considered a transition metal.
  4. If the strength of aluminium is one, then the strength of titanium is two, which means titanium has double the strength of aluminium.
  5. When compared to aluminium, titanium has 60% greater strength.
