2. List of thermal conductivities - Wikipedia

   en.wikipedia.org/wiki/List_of_thermal_conductivities

   Small granite pillars have failed under loads that averaged out to about 1.43 ⋅ 10 8 Newtons/meter 2 and this kind of rock has a sonic speed of about 5.6 ± 0.3 ⋅ 10 3 m/sec (stp), a density of about 2.7 g/cm 3 and specific heat ranging from about 0.2 to 0.3 cal/g °C through the temperature interval 100-1000 °C [Stowe pages 41 & 59 and ...

3. Comparative Tracking Index - Wikipedia

   en.wikipedia.org/wiki/Comparative_Tracking_Index

   To measure the tracking, 50 drops of 0.1% ammonium chloride solution are dropped on the material, and the voltage measured for a 3 mm thickness is considered representative of the material performance. Also term PTI (Proof Tracking Index) is used: it means voltage at which during testing on five samples the samples pass the test with no failures.

4. List of copper alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_copper_alloys

   Example of a copper alloy object: a Neo-Sumerian foundation figure 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.

5. Beryllium copper - Wikipedia

   en.wikipedia.org/wiki/Beryllium_copper

   Beryllium copper attains the greatest strength (up to 1,400 MPa (200,000 psi)) of any copper-based alloy. [3] It has thermal conductivity of 62 Btu/h-ft-°F (107 W/m-K), which is 3–5 times higher than tool steel. It has a solid melting point of 1590 °F (866 °C) and a liquid melting point of 1800 °F (982 °C). It has a high capacity for ...

   Silver, a common component of brazing alloys, can be problematic at higher temperatures and lower pressures. A silver-copper eutectic, named e.g. Cusil, is recommended. A superior alternative is a copper-silver-tin alloy called Cusiltin. Copper-silver-phosphorus alloys, e.g. Sil-Fos, are also suitable. [3]

7. Copper foil - Wikipedia

   en.wikipedia.org/wiki/Copper_foil

   Copper foil is a thin sheet of copper metal that is widely used in various applications due to its excellent electrical conductivity, malleability, and corrosion resistance. It is an essential material in the electronics industry, especially for manufacturing printed circuit boards (PCBs) and other electronic components.

8. Daniel Fox (chemist) - Wikipedia

   LEXAN is the flagship product of SABIC Innovative Plastics (formerly GE Plastics) and is used in everything from CDs and DVDs to car bumpers. Though Dr. Fox is often credited with the invention of LEXAN resin, the patent and agreement to share the plastic between Bayer and General Electric is much more complicated than the simplistic "Father of ...

9. Terne - Wikipedia

   en.wikipedia.org/wiki/Terne

   Terne metal can last 90 years or more if the paint is maintained. Terne-coated stainless steel (TCS II or Roofinox), or copper is commonly used to replace terne metal roofs as either material will outlast terne metal. Terne-coated stainless steel roofing can last 100 years or more unpainted; copper roofing can last 50 years or more unpainted ...
