When it comes to house wiring, definitely, the copper wire and cable would be a better choice and it is not because of illegal concerns or matters. Because aluminum wiring was less expensive than copper wiring at the time, it was used in the construction of many homes in the late 1960s and early 1970s. The most significant issue that can arise with aluminum wiring is the metal's tendency to swell when it's heated and then contract after it's cooled down. These changes in size have the potential to cause wires to become disconnected. When they escape their confinement, they have the potential to produce a spark or an arc, which can subsequently lead to the beginning of a fire. Things You Need to Consider Before Purchasing a Home That Has Aluminum Wiring 
IRI Before you purchase the home, it is highly recommended that you take the following precautions: In addition to having a standard house inspector take a look at everything, you should hire an electrician to perform an inspection of the entire system to ensure that there are not any significant problems with the wiring at this time. You should ask the electrician for an estimate of how much it would cost to switch all of the wiring in the house over to copper. You might be able to utilize this information to your advantage while negotiating the price of your house. If the electrician suggests a less expensive alternative, you should receive a price for that alternative, and you should factor that choice into your decision regarding whether or not to purchase the home. Check to see that there is not an excessive load being carried by a single wire that is exiting the panel. For instance, there should not be a single wire supplying power to one half of the house or to both the kitchen and the washing room at the same time. At this point, an aluminum wire may begin to overheat, causing you to experience a variety of difficulties. Call an agency that specializes in homeowner's insurance and inquire about the cost of insuring the house if it has aluminum wiring. There is a possibility that you will have trouble obtaining insurance, which will prevent you from purchasing the home. 
I recently tried to shop around for different homeowner's insurance providers and was successful in finding a lower premium. However, after learning that our home is wired with aluminum, the agent informed us that they will not be able to insure the property. If you intend to use FHA financing, check to see that the house will meet the requirements to be approved by the FHA. How to Ensure the Security of Your Home When Using Aluminum Wiring You recently discovered that the house you are interested in purchasing has aluminum wiring, and at this point, you are not sure whether or not you want to forward with the purchase. The following is a list of steps that can be taken to make your home safer if it contains aluminum wire, beginning with the least expensive and working up to the most expensive. Install plugs and sockets that are resistant to corrosion from aluminum wiring. There are some electricians in the world who do not think this is the greatest way because it is possible that you may still have issues in the long run. On the other hand, these receptacles are a significant improvement over those designed specifically for copper wire. Connect a wire made of aluminum to one made of copper using a pigtail. To accomplish this, you would essentially need to twist a unique purple wire nut over both of the wires. 
A substance that prevents oxidation and, consequently, the buildup of heat at the connecting points is contained within the wire nut and may be found on its interior. You should mentally prepare yourself for the possibility that potential purchasers of your property will be concerned about the aluminum wiring that is now installed in it. The truth of the matter is that this will either set you back some money right off the bat or set you back during the process of negotiating the sale of your house. First and foremost, I strongly suggest that you consult with a licensed electrician about the possibility of rewiring your home with copper. Gather as many estimates as you can and keep the one that's the lowest. You already have an estimate in your hand that may be used as the cost basis in the event that potential customers in the future are seeking for a price reduction to deal with the aluminum wire. In lieu of having the wiring redone, inquire with the electricians about other alternatives, and get estimates for both of them. Pig tailing can be a solution that the purchasers are willing to compromise on. 
Do not lose a sale because of a problem with the wiring. The majority of purchasers are likely to have issues with aluminum wire. Therefore, it is important to just realize it and know in advance what you are willing to do in terms of the negotiation, as this will help you the most. If you are buying or selling an older home that has aluminum wiring, the home inspector will be obliged to look for aluminum wiring and provide a report if single-strand aluminum wiring is found in the home. This is the case regardless of whether you are buying or selling the property. The inspector will also check to see if any corrective actions have been taken to eliminate or reduce the risk of any potential danger. The following are examples of some of these treatments: Crimping an aluminum wire onto a copper wire using a tool and sleeve that have been specifically created for the purpose is what is known as the copalum crimping procedure. This procedure costs roughly $50 for each outlet or switch that needs to be installed. Pigtailing is a method that, despite being less desirable, is less expensive and can be used to effectively combine aluminum and copper wires into a single conductor. This is something that the house inspector will look for as a potential solution. The inspector will check to see if you are utilizing CO/ALR switches and outlets, as these are the types of outlets that are the most suitable with aluminum wiring. 
You should anticipate seeing some notation and advice from the home inspector if the home has not undergone any process to make the home safe from aluminum wire. If this is the case, the home has not been safe from aluminum wiring. If you are planning to sell your home, you should consider getting a pre-listing home inspection to determine whether or not there are any repairs or improvements that need to be made before placing the home on the market. Although aluminum wire is not against the law, it is not compliant with current building standards, and as a result, copper wiring is used in all newly constructed homes. If you are considering purchasing or selling a home that has aluminum wiring, you do not need to worry if you follow the directions on how to deal with it because you will not be affected by it in any way.
