2. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   Hot-dip galvanization. Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O 2 ...

3. Aluminized steel - Wikipedia

   en.wikipedia.org/wiki/Aluminized_steel

   Aluminized steel. Aluminized steel is steel that has been plated with aluminium or aluminium - silicon alloy, in a process analogous to hot-dip galvanizing. The steel workpiece is immersed in molten aluminum to produce a tight metallic bond between the steel and coating. The product has a unique combination of properties possessed by neither ...

4. Electrical conduit - Wikipedia

   Electrical conduit and bus duct in a building at Texaco Nanticoke refinery. An electrical conduit is a tube used to protect and route electrical wiring in a building or structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.

   YD1336 – 1.8 kW, Air-cooled, UHF power triode. YD1342 – 30 MHz, 530 kW, Water-cooled RF power triode. YD1352S (8867, DX334) – 5 MHz, 2 kW, Water-cooled Neotron, a gridless field-effect tube where a magnetically focused electron beam is modulated by varying the voltage of a gate electrode surrounding it.

6. SAE 304 stainless steel - Wikipedia

   en.wikipedia.org/wiki/SAE_304_stainless_steel

   SAE 304 stainless steel is the most common stainless steel. It is an alloy of iron, carbon, chromium and nickel. It is an austenitic stainless steel, and is therefore not magnetic. It is less electrically and thermally conductive than carbon steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in ...

7. Copper tubing - Wikipedia

   en.wikipedia.org/wiki/Copper_tubing

   Rigid copper is a popular choice for water lines. Rigid or "Hard" copper tubing is generally referred to as "pipe". Copper "piping" is referred to by nominal pipe size, or the inner diameter. It is joined using a solder/sweat, roll grooved, compression, or crimped/pressed connection. Rigid copper, rigid due to the work hardening of the drawing ...
