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...

   Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium , chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.

4. ACCC conductor - Wikipedia

   en.wikipedia.org/wiki/ACCC_conductor

   The primary disadvantage is cost; ACCC costs 2.5–3 times as much as ACSR cable. [ 9 ] Although ACCC has significantly less thermal sag than even other HTLS conductor designs, it has a lower axial stiffness. [ 10 ]

5. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   The conduit may be coated to prevent corrosion by incidental contact with concrete. Aluminum conduit is generally lower cost than steel in addition to having a lower labor cost to install, since a length of aluminum conduit will have about one-third the weight of an equally-sized rigid steel conduit. [2]

6. 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 ...

7. Wire bonding - Wikipedia

   en.wikipedia.org/wiki/Wire_bonding

   Copper is used for fine wire ball bonding in sizes from 10 micrometers (0.00039 in) up to 75 micrometers (0.003 in). [6] Copper wire has the ability of being used at smaller diameters providing the same performance as gold without the high material cost.

9. Copper-clad aluminium wire - Wikipedia

   en.wikipedia.org/wiki/Copper-clad_aluminium_wire

   This improved conductivity over bare aluminum makes the copper-clad aluminium wire a good fit for radio frequency use. The skin effect is similarly exploited in copper-clad steel wire, such as the center conductors of many coaxial cables , which are commonly used for high frequency feedlines with high strength and conductivity requirements.
