2. Glossary of rail transport terms - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_rail_transport...

   The form invented by William Buchanan, of the N. Y. C. & H. R. R. R., consists of two flat, parallel plates, extending diagonally upward from the tube sheet to the back sheet of the firebox. These plates are about 4 Ms inches apart, are strengthened with staybolts in the same manner as are the inner and outer firebox sheets, and form an ...

3. Stamping (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Stamping_(metalworking)

   Stamping (metalworking) Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a machine press or stamping ...

4. Rolling (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Rolling_(metalworking)

   Rolling (metalworking) In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of ...

5. Continuous casting - Wikipedia

   en.wikipedia.org/wiki/Continuous_casting

   Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...

6. Copper - Wikipedia

   en.wikipedia.org/wiki/Copper

   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 ...

7. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips.

8. List of copper alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_copper_alloys

   Example of a copper alloy object: a Neo-Sumerian "Foundation Nail" of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.

9. Plating - Wikipedia

   en.wikipedia.org/wiki/Plating

   Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
