The Evolution engine (popularly known as Evo and sometimes as Blockhead ) is an air-cooled, 45-degree, V-twin engine manufactured from 1984 by Harley-Davidson for the company's motorcycles. It was made in the 1,340 cc (82 cu in) displacement for Harley-Davidson Big V-twins bikes, replacing the Shovelhead engine until 2000 when the last EVO was ...
Anodizing. Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell.
v. t. e. The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718 281 828 459. [1] The natural logarithm of x is generally written as ln x, loge x, or sometimes, if the base e is implicit, simply log x.
Aluminium phosphide is a highly toxic inorganic compound with the chemical formula AlP, used as a wide band gap semiconductor and a fumigant. This colorless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation .
Aluminum piano plate. A piano with an aluminum piano plate, called the Alumatone plate, was announced in 1945 by Winter and Company, piano manufacturers, and Alcoa, a manufacturer of aluminum and aluminum products. [1] The metal frame of a piano, often called the plate or harp, anchors both ends of the strings, withstanding a tension of 20 tons ...

Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the ...
When Zinsco changed to an aluminum bus, the aluminum selected was Alloy 6061. First developed in 1935, Alloy 6061 is a good conductor, a hard aluminum, and still a popular alloy for welding today. But in 1961, another aluminum alloy was developed: 6101. This alloy has a higher tensile strength and is the best conductor for electrical use.
