The problem with aluminum wiring (common 1965-1975) is not the wire itself but the connections. Aluminum oxidizes, creating resistance. Per CPSC guidelines, use CO/ALR-rated devices, Alumiconn connectors, or COPALUM crimps for aluminum-to-copper transitions. Never use wire nuts alone for AL/CU connections. A qualified electrician can make aluminum wiring safe for the life of the home.
