Aluminum conductors are larger than copper conductors for the same ampacity, and code sizing, compatible terminals, installation conditions, and labor all affect the decision. The reviewed sources establish no universal installed-cost winner. For legacy aluminum branch-circuit wiring in a home, consult a qualified electrician rather than inspecting or repairing it yourself.
How copper and aluminum compare
| Factor | Copper | Aluminum |
|---|---|---|
| Electrical conductivity by equal volume | 101% IACS at 20°C in a historical property table reproduced by the National Bureau of Standards in 1974 and attributed to a 1968 source. | 62% IACS at 20°C in the same historical property table. |
| Conductor size for the same ampacity | Smaller than aluminum, according to UL Solutions. | Larger than copper, according to UL Solutions. |
| Installed cost | No current apples-to-apples installed-cost figure established by the reviewed sources. | No current apples-to-apples installed-cost figure established by the reviewed sources. |
The conductivity figures compare typical material properties per equal volume; they are not ampacity ratings and do not tell you which wire size a particular installation permits. The historical table appears in the [National Bureau of Standards’ 1974 summary report].
Conductivity does not determine wire size by itself
For the same ampacity, aluminum conductors are physically larger than copper conductors, as UL Solutions explains in its Panelboard Application Guide. Do not treat equal AWG copper and aluminum conductors as interchangeable or infer an allowable wire size from conductivity alone.
Ampacity and permitted conductor size depend on the conductor material, insulation and temperature ratings, installation conditions, connected equipment, and the electrical code adopted by the local jurisdiction. As one dated model-code example, the 2018 International Residential Code gives minimum sizes of 14 AWG copper and 12 AWG aluminum for feeders and branch circuits. That is not a complete sizing calculation or a statement of what a particular jurisdiction currently enforces; local adoption and amendments control.

- Exact Gauge And Length You Can Plan Around: This copper wire spool holds 100ft / 30.48 m of 24 AWG copper wire measuring 0.02inch/ 0.5mm in diameter. Remember the higher the gauge number, the thinner the wire — if this thickness is not the one your project needs, the size menu above covers 16 gauges from heavy 4 AWG to fine 34 AWG so you can pick by load instead of guessing
- Made For Wire Wrapping And Jewelry Making: A practical length of copper wire for jewelry making, this gauge threads through most beads and bends into tight coils by hand Use it for wire wrapping, jump rings, ear wires, beaded bracelets, pendant frames and chain links. Fine enough to loop repeatedly without fighting the wire, so it suits both first projects and detailed copper jewelry wire designs
- 99.9% Pure Bare Copper, No Coating To Strip: Made of 99.9% pure copper wire with no insulation, so you can cut and shape it straight off the spool with regular pliers instead of stripping a jacket first. As uncoated bare copper wire it conducts well and gradually darkens into a natural patina with air exposure — a normal property of raw copper rather than a defect, and a tone many makers keep on finished pieces
- One Spool For Craft, Garden And Hobby Projects: Beyond copper jewelry making supplies, this soft copper wire works for electroculture garden antennas, plant and bonsai shaping, floral arranging, model and sculpture armatures, holiday DIY decor, weaving and low-voltage hobby circuit connections. Pair it with a thicker or thinner gauge from the same size menu when a project needs both a frame wire and a detail wire
- Easy To Bend, Store And Handle: The wire bends readily and holds the shape you set, and it ships on its own spool so the wire stays untangled on a bench and travels easily in a craft bag. Spool style may vary, wire length is the same either way. Safety note: this is uninsulated bare wire and cut ends can be sharp — wear gloves or handle cut pieces carefully
Terminals and connectors must match the conductors
Do not assume a terminal that accepts copper will also accept aluminum. UL Solutions says equipment wiring diagrams or nameplates must indicate whether aluminum wire may be used when aluminum is connected to the equipment. Check the actual equipment markings and follow the manufacturer’s instructions.
NEMA’s discussion of the 2020 National Electrical Code describes separate ampacity columns for copper-clad aluminum and aluminum conductors versus copper. It also explains that dissimilar metals should not be intermixed in a terminal or splicing connector unless the device is identified for that purpose and the conditions of use are met. See NEMA’s explanation of copper-clad aluminum conductor requirements. Confirm the currently adopted local code and the equipment instructions for an actual installation.

Which material is cheaper to install?
The reviewed sources do not establish current installed-cost figures or a universal price winner. A fair comparison must use quotes for the same project scope and required load, not simply compare the price of equal lengths or equal AWG sizes.
Ask each contractor to account for the required conductor size and type, compatible equipment and terminals, local material prices, labor, installation environment, and any code-required changes. Aluminum’s larger size for the same ampacity can affect what equipment and connections are suitable; the project details determine whether either material costs less overall.

Is aluminum wiring safe in a home?
“Aluminum wiring” covers different applications and eras. The Consumer Product Safety Commission’s 1974 warning concerned reported overheating connections and fires involving older residential branch-circuit wiring. It is not a finding that every modern aluminum conductor application is unsafe. The CPSC estimated in 1974 that two million homes and mobile homes had been constructed using aluminum wiring since 1965; that historical estimate is not a count of homes that currently contain it. See the CPSC’s 1974 safety notice.
The CPSC advised consumers without thorough electrical training not to inspect or repair home wiring where aluminum wiring may be present, and to seek expert advice. If you suspect legacy aluminum branch-circuit wiring, arrange an assessment with a qualified electrician. Do not open devices, inspect wiring, or attempt repairs yourself.

How to compare options for a real project
- Define the load and installation. Have the required ampacity, wiring route, environment, and applicable local code requirements established for the project.
- Compare the specified conductors. Check material, conductor size, insulation and temperature ratings, and listing; do not compare equal AWG copper and aluminum as though their ampacity were identical.
- Verify connection compatibility. Confirm that equipment terminals and any splicing connectors are identified for the conductor material, sizes, and conditions of use.
- Compare complete, same-scope quotes. Include conductor, compatible equipment and connectors, labor, and required upgrades, rather than judging by conductor price alone.
- For suspected older home wiring, involve a qualified electrician. Use professional assessment rather than a do-it-yourself inspection or repair.
