  2. Arithmetic logic unit - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_logic_unit

    An ALU has a variety of input and output nets, which are the electrical conductors used to convey digital signals between the ALU and external circuitry. When an ALU is operating, external circuits apply signals to the ALU inputs and, in response, the ALU produces and conveys signals to external circuitry via its outputs.

  3. Aluminium - Wikipedia

    en.wikipedia.org/wiki/Aluminium

    Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals , about one-third that of steel .

  4. Aluminium–copper alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–copper_alloys

    Used for aircraft applications between the wars in France and Italy. [35] Also saw some use in motor-racing applications from the 1960s, [36] as it is a tolerant alloy that could be press-formed with relatively unsophisticated equipment. 2024: Aircraft structures, rivets, hardware, truck wheels, screw machine products, and other structural ...

  5. Aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/Aluminium_alloy

    An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin , nickel and zinc .

  6. Aluminium–silicon alloys - Wikipedia

    en.wikipedia.org/wiki/Aluminium–silicon_alloys

    Aluminum-silicon phase diagram. Aluminum forms a eutectic with silicon, which is at 577 °C, with a Si content of 12.5% [7] or 12.6%. [8] Up to 1.65% Si can be dissolved in aluminum at this temperature. However, the solubility decreases rapidly with temperature. At 500 °C it is still 0.8% Si, at 400 °C 0.3% Si and at 250 °C only 0.05% Si.

  7. 7075 aluminium alloy - Wikipedia

    en.wikipedia.org/wiki/7075_aluminium_alloy

    It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. [ 2 ] 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc , 2.1–2.5% magnesium , 1.2–1.6% copper , and less than a half percent of silicon, iron, manganese, titanium ...

    Aluminium oxide catalyses a variety of reactions that are useful industrially. In its largest scale application, aluminium oxide is the catalyst in the Claus process for converting hydrogen sulfide waste gases into elemental sulfur in refineries.

  9. 74181 - Wikipedia

    en.wikipedia.org/wiki/74181

    The 74S181 4-bit ALU bitslice resting on a page from the datasheet. The 74181 is a 4-bit slice arithmetic logic unit (ALU), implemented as a 7400 series TTL integrated circuit. Introduced by Texas Instruments in February 1970, [1] it was the first complete ALU on a single chip. [2]
