Based on the age it is tinned copper. 44 Votes) Copper is always best for any electrical application, but copper is expensive, so there are some alternatives available, including aluminum, copper-clad aluminum. "Repairing" aluminum wiring means an electrician simply attaches a short section of copper cable to the end of the aluminum wire at every connection point in your home.This process is called "pigtailing." With this process, copper cable, instead of aluminum, connects to electrical devices.Since copper is sturdier and far less likely to overheat and breakdown, this prevents overheating. Between approximately 1965 and 1973, single-strand (solid) aluminum wiring was sometimes substituted for copper branch-circuit wiring in residential electrical systems due to the sudden escalating price of copper. The price difference between aluminum and copper wire is amazing in the US, $30 extra for 1Kg copper. After a decade of use by homeowners and electricians, inherent weaknesses were discovered in the metal that lead to its disuse as a branch wiring material. Look at the receptacle wiring. And it is also a soft and pliable metal that is easily fashioned into a wire. While aluminum may initially seem appealing due to its lighter weight and lower cost, copper is the better option.

Re: Advantage of Aluminum wiring vs Copper wiring in power tools I do believe it is a cost cutting measure, but the insulation most likely would break down before the wire it self regardless if it Aluminum or copper, for most instances I doubt if the consumer will see any difference in the operation of the machine, However, it also offers many other advantages . The homeowner may choose to replace the solid aluminum wire with copper wiring. The main difference between Aluminum Wire and Copper Wire is that both have different properties, and this is because of their respective metal. While it may seem like a sound alternative at first thought, it was quickly discovered that aluminum wiring was by no means comparable to copper. 12.9 If you run aluminum you would have to run approximately one size larger aluminum wire that you would if it was copper, because of the increased resistance. Aluminum Vs. Copper Wiring - Bryant Electric Service. Between approximately 1965 and 1973, single-strand (solid) aluminum wiring was sometimes substituted for copper branch-circuit wiring in residential electrical systems due to the sudden escalating price of copper.
