Older solid aluminum wire also had some problems with a property called creep, which results in the wire permanently deforming or relaxing over time under load. Aluminum wire used before the mid-1970s had a somewhat higher rate of creep, but a more significant issue was that the same high price of copper driving the use of aluminum wire led to ...
The resistance of copper wire is approximately 1 ohms / 1000 feet for 10 AWG, 10 ohms / 1000 feet for 20 AWG, 100 ohms / 1000 feet for 30 AWG, and so on. [ 5 ] : 27 Because aluminum wire has a conductivity of approximately 61% of copper, an aluminum wire has nearly the same resistance as a copper wire that is two sizes ...
This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards. [1] The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2.
The wire and 1 ⁄ 4 in (6.4 mm) of insulated wire are placed in a hole near the edge of the tool. The hole in the center of the tool is placed over the post. The tool is rapidly twisted. The result is that 1.5 to 2 turns of insulated wire are wrapped around the post, and above that, 7 to 9 turns of bare wire are wrapped around the post.

A copper strip is formed into the shape of a cylinder, while it is being wrapped around an aluminum core and the edges of the copper strip are welded together. The assembly is then pulled through a die, where the cladded wire is squeezed and stretched while also improving the bonding between the copper and the aluminum core. [1]
