2. Aluminum building wiring - Wikipedia

   en.wikipedia.org/wiki/Aluminum_building_wiring

   Since copper costs about four times as much as aluminum by weight (roughly US$4 /lb [5] vs. US$1 /lb [6] as of 2024), aluminum wires are one-eighth the cost of copper wire of the same conductivity.

3. Aluminium-conductor steel-reinforced cable - Wikipedia

   en.wikipedia.org/wiki/Aluminium-conductor_steel...

   Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.

   S&P Global Commodity Insights is a provider of energy and commodities information and a source of benchmark price assessments in the physical commodity markets. The business was started with the foundation in 1909 of the magazine National Petroleum News by Warren C. Platt. [4]

5. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   In the North American electrical industry, conductors thicker than 4/0 AWG are generally identified by the area in thousands of circular mils (kcmil), where 1 kcmil = 0.5067 mm 2. The next wire size thicker than 4/0 has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area ...

   The contracts prices are quoted in US dollars per tonne. LME prices have minimum tick sizes of $0.50 per tonne (or $12.50 for one contract) for open outcry trading in the LME Ring and electronic trading on LMEselect, while minimum tick sizes are reduced for inter-office telephone trading to $0.01 per tonne (or $0.50 for one contract).

8. Electrical conductor - Wikipedia

   en.wikipedia.org/wiki/Electrical_conductor

   Although only 61% of the conductivity of copper by cross-sectional area, its lower density makes it twice as conductive by mass. As aluminum is roughly one-third the cost of copper by weight, the economic advantages are considerable when large conductors are required. The disadvantages of aluminum wiring lie in its mechanical and chemical ...

9. Wire bonding - Wikipedia

   en.wikipedia.org/wiki/Wire_bonding

   Smaller diameters are possible due to copper's higher electrical conductivity. Copper wire bonds are at least as reliable if not more reliable than gold wire bonds. [7] Copper wire up to 500 micrometers (0.02 in) [8] can be successfully wedge bonded. Large diameter copper wire can and does replace aluminium wire where high current carrying ...
