83003508 [1] Added to NRHP. November 29, 1983. The Main Street Historic District in Danbury, Connecticut, United States, is the oldest section of that city, at its geographical center. It has long been the city's commercial core and downtown. Its 132 buildings, 97 of which are considered contributing properties, include government buildings ...
The name is mainly used in pop-science to describe all Al-Cu alloys system. Aluminium–copper alloys were standardised in the 2000 series by the international alloy designation system (IADS) which was originally created in 1970 by the Aluminum Association. 2000s series includes 2014 and 2024 alloys used in airframe fabrication.
Tellurium is usually added to copper to improve machinability ("free cutting"). ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved while electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper, while machinability is similar to ...
The hardness is comparable to many copper-beryllium and copper-tungsten alloys, while the electrical conductivity is comparable to RWMA Class 2 alloy. Other additives for specialized applications include molybdenum, tungsten, Kovar, and Alloy 42. [3] At 500 °C (932 °F), Glidcop AL-15 has a yield strength of over 29 ksi (200 MPa). [3]
Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...
Alloy wheel. In the automotive industry, alloy wheels are wheels that are made from an alloy of aluminium or magnesium. Alloys are mixtures of a metal and other elements. They generally provide greater strength over pure metals, which are usually much softer and more ductile. Alloys of aluminium or magnesium are typically lighter for the same ...
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids, such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper ...
