"Aluminium" Natural Recordings by Native Speakers
Aluminium (also spelled aluminum in American English) is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic, and ductile metal in the boron group. Aluminium is the third most abundant element in the Earth's crust after oxygen and silicon, and it is the most abundant metal. It is widely used in various industries due to its properties such as lightweight, corrosion resistance, and ability to be easily formed and molded. It is found in alloys, cans, foil, aircraft parts, cooking utensils, and many other products.
1. Aluminium foil: I wrapped the leftover food in aluminium foil to keep it fresh for later.
2. Aluminium cans: Recycling centres accept aluminium cans, which can be melted down and reused.
3. Aluminium cookware: Many chefs prefer using aluminium pots and pans for their even heat distribution.
4. Aluminium window frames: Modern houses often have aluminium window frames for durability and low maintenance.
5. Aluminium bats: In baseball, aluminium bats are popular among amateur players due to their lighter weight and increased hitting speed.
Aluminate refers to a compound or salt formed by the combination of aluminum with another element or radical, usually in the presence of an alkali or alkaline earth metal. It often denotes materials containing aluminum ions (Al3+) bound to anionic species such as oxygen or other polyatomic ions. Examples include sodium aluminate (NaAlO2), which is a common ingredient in water treatment and cement production.
"Alumine" is a variant spelling of "alumina," which refers to a chemical compound, aluminum oxide (Al2O3). It is a white, crystalline substance that is commonly used in various industries, such as ceramics, refractories, and as an abrasive. Alumina is also the primary raw material in the production of aluminum metal.
"Aluminic" is an adjective used to describe something that contains aluminum or is related to aluminum. It refers to compounds or materials with aluminum as a significant component.
Aluminide refers to a compound or alloy formed by combining aluminum with another element, typically a metal such as nickel, titanium, or iron. These alloys have useful properties, including high temperature resistance and corrosion resistance, making them suitable for applications in aerospace, automotive, and chemical industries.
Aluminides are a class of intermetallic compounds that contain aluminum (Al) combined with other elements, typically transition metals or rare earth metals. These compounds have a high aluminum content and exhibit unique properties, such as high melting points, excellent thermal and chemical stability, and strong resistance to corrosion. Aluminides are often used in aerospace and automotive industries for their high-temperature performance and as coatings for protective purposes.
Aluminiferous refers to containing or yielding aluminum. It is often used in the context of minerals or rocks that have a significant amount of aluminum in their composition.
To aluminise means to coat or treat a surface with aluminum or an aluminum alloy, typically through a process such as vapor deposition or chemical conversion, to improve its properties like corrosion resistance, heat resistance, or wear resistance.
"Aluminised" refers to a process where a surface, typically metal, is coated or treated with aluminum to provide protection against corrosion, heat resistance, or to improve its reflective properties. It can also describe items made from or covered with an aluminum alloy.
