Difference Between Aluminum and Titanium
Aluminum vs Titanium
Aluminum and titanium are both metals that occur naturally in the Earth’s crust. Aluminum and titanium are known for their high strength-to-weight ratio. Aluminum is lightweight, durable, soft and malleable, whereas titanium is strong with a low density and ductility. Aluminum is silvery grey, and titanium is metallic, lustrous white in color. Titanium has a high melting point of over 1,649 Â°C or 3,000 Â°F, and is a refractory metal, whereas aluminum is non-sparking. Aluminum and titanium are both nonmagnetic and reactive.
Aluminum is insoluble in alcohol, and titanium is soluble in concentrated acids. Aluminum is ductile and easily machined cast, drawn and extruded when compared to titanium, which needs precaution as it loses strength when heated above 430 Â°C. Titanium has more resistance to corrosion compared to aluminum. Aluminium has a low metal density, whereas titanium is 60% denser. Aluminum is strong, but titanium is stronger than aluminum. Aluminum is a excellent conductor of heat and electricity, whereas titanum is a poor conductor.
Structural components vital to the aerospace industry, transportation and building are made by aluminum, when compared to titanium structures that have a fatigue limit. Aluminum is in abundance on Earth, as it is the 3rd most abundant metal, and is found in the silicates state; whereas, titanium is the 9th most abundant element, and 7th most abundant metal present in igneous rocks, sediments and also detected in meteorites. Titanium is commercially produced by the expensive and complex Kroll process, which makes it one of the most expensive metals available.
Titanium and aluminum are both used to make alloys, such as titanium alloys with aluminum and steel, whereas aluminum is alloyed with copper and zinc. Titanium and aluminum are both used as powders, such as aluminum powder is used to make an artist’s silver paints, and titanium powder is used to make household paints. Aluminum and titanium are both used in aerospace, marine and computer manufacturing and technology. Both the metals have high tensile strength to density ratio, corrosion, fatigue and high crack resistance, with the ability to withstand thermal and temperature changes.
Titanium is twice as strong as aluminum, and much lighter. Titanium is also used for dental implants, and aluminum is used as a hygienic metal. Aluminum has a recycling quality, whereas titanium has resistance to salt water. Titanic versus aluminum is extremely springy, is regarded as hypoallergenic, and does not discolor the skin. Aluminum is used for cans, foils and kitchen utensils, decorative and industrial applications. Titanium is known as space age metal, whereas aluminum is used in the construction of rockets and aircrafts. It is relatively much cheaper and stain resistant, with less bending, and is preferred over titanium for its cheap prices.
1. Aluminum is the 3rd most abundant metal, and titanium is the 9th most abundant element and 7th most abundant metal found on Earth.
2. Aluminum can be recycled, and titanium is hypoallergenic.
3. Titanium is more expensive than, and twice as strong as aluminum, and poor conductor, whereas aluminum is an excellent conductor.
4. Aluminum is a decorative and industrial metal, whereas titanium is known as space age metal.
5. Titanium and aluminum are both ductile, anti corrosive and non magnetic metals.
