2. Prices of chemical elements - Wikipedia

   en.wikipedia.org/wiki/Prices_of_chemical_elements

   Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram. [21] 7: N: Nitrogen: 0.0012506: 19 (5.263 × 10 17 kg) 0. ...

3. Tungsten - Wikipedia

   en.wikipedia.org/wiki/Tungsten

   Tungsten's heat resistance makes it useful in arc welding applications when combined with another highly-conductive metal such as silver or copper. The silver or copper provides the necessary conductivity and the tungsten allows the welding rod to withstand the high temperatures of the arc welding environment. [84]

4. Silver steel - Wikipedia

   en.wikipedia.org/wiki/Silver_steel

   Amongst other applications, it has been widely used to make such things as punches, engravers, and screwdrivers. Sheffield silver steel is used in France as a blade steel for straight razors. In Finland, German silver steel was and still is widely used for Puukko knives. The composition is defined by the British Standard BS-1407, and is given ...

5. List of brazing alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_brazing_alloys

   For iron or nickel alloys. Silver-white color; used in silversmithing due to color match. Low zinc content minimizes zinc evaporation, especially in controlled atmospheres during fluxless brazing. 22: 3: 75: Ag 50 Cu 34 Zn 16: Ag–Cu–Zn 675/775 [41] 677/774 [53] – BAg-6, Braze 501, Braze 502, Braze 503, Silvaloy A50, Silver Braze 50.

6. Filler metal - Wikipedia

   en.wikipedia.org/wiki/Filler_metal

   Many gas welding processes, such as lead burning, are typically autogenous and a separate wire filler rod of the same metal is only added if there is a gap to fill. Some metals, such as lead or Birmabright aluminium alloy, use offcut strips of the same metal as filler.

7. Equivalent carbon content - Wikipedia

   en.wikipedia.org/wiki/Equivalent_carbon_content

   One is from the American Welding Society (AWS) and recommended for structural steels and the other is the formula based on the International Institute of Welding (IIW). [3] The AWS states that for an equivalent carbon content above 0.40% there is a potential for cracking in the heat-affected zone (HAZ) on flame cut edges and welds. However ...

9. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   The rods could be a metal coated in oil to prevent the rod oxidising if needed or in more complicated welding of metals the rod would be coated in a "flux" that was not an active flux but a method of protecting the welding rods from oxidisation during storage (the major examples of this were rods for welding; pure aluminium, duralumin ...
