The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added. They have higher strength and corrosion resistance than other bronzes, especially in marine environment, and have low reactivity to sulphur compounds. Aluminium forms a thin passivation layer on the surface of the metal. Bell metal
Reactivity series. In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest. [2][3][4] It is used to summarize information about the reactions of metals with acids and water, single ...
Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules, which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain. The Clarion-Clipperton Zone (CCZ) alone contains over 21 billion metric tons of these nodules, with minerals such as ...
Carbon dioxide is a chemical compound with the chemical formula CO2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric CO 2 is ...
Flower. A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. These petals attract pollinators, and reproductive organs that produce gametophytes ...
Corinthian bronze (gold, silver) Cunife (nickel, iron) Cupronickel (nickel) CuSil (silver) Cymbal alloys (tin) Devarda's alloy (aluminium, zinc) Hepatizon (gold, silver) Manganin (manganese, nickel) Melchior (nickel); high corrosion resistance, used in marine applications in condenser tubes.
5083 aluminium alloy is an aluminium–magnesium alloy with magnesium and traces of manganese and chromium. It is highly resistant to attack by seawater and industrial chemicals. [1] Alloy 5083 retains exceptional strength after welding. It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or ...
International Space Station. The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). The ISS is the largest space station ever ...
