Aluminium wire and conductor: alloy, temper and what it is worth
Aluminium arrives in two economies. Building wire in AA-8000 alloy sits on a storehouse shelf, and overhead conductor sits on a timber reel in a utility yard with the steel core showing at the end.
- AA-8000 building wire
- ACSR and 1350-H19
- Not priced as copper
The alloy question comes first. Aluminium building wire must be an AA-8000 series alloy to be listed for the purpose, and that is what any modern XHHW-2 or SER aluminium conductor will be. Older aluminium building wire from before that requirement is a different material with a different history, and a buyer needs to know which one is in front of them before any number is discussed. The print on the jacket settles it wherever the print survives.
Overhead conductor is a separate market. 1350-H19 is the hard-drawn electrical conductor aluminium used in AAC and as the outer strands of ACSR, where a galvanised steel or aluminium-clad steel core carries the tension. ACAR and AAAC sit alongside for utilities that want more strength or a different sag characteristic. None of it is insulated, and all of it is priced against the aluminium market rather than the copper one.
We buy both, along with aluminium SER and SEU from service work, aluminium URD and USE-2, and compact stranded feeder in the larger sizes. What we will not do is talk about aluminium as though it were copper in a different colour. It is a different market, a different weight per foot, and a different set of terminations. Two markets, two sets of buyers, and one conversation that has to be honest.
What we buy in this family
Condition and documentation decide the basis, not the family alone. These are the forms this material usually arrives in.
- AA-8000 aluminium building wire
- Aluminium XHHW-2 and SER
- ACSR and AAC overhead conductor
- 1350-H19 bare aluminium conductor
- Compact and stranded aluminium feeder
- Aluminium URD and USE-2
- Mixed aluminium with alloy marking
AA-8000, 1350 and the alloys that came before
AA-8000 is a family of alloys formulated for building wire, with the creep and termination behaviour that made aluminium acceptable again after the difficulties of the 1960s and 1970s. 1350 is a different animal: electrical conductor aluminium chosen for conductivity and drawn to H19 temper so it can carry tension between structures. Both are aluminium, and neither substitutes for the other.
The practical consequence is that a reel of building wire and a reel of ACSR are reviewed by different people for different reasons. One is judged on insulation, alloy series and footage. The other on stranding, core condition, diameter and length, where the jacket, if any, is irrelevant.
Why the weight is not the answer
A seller who has moved copper before often assumes an aluminium pallet will carry a similar number. It will not, and not only because the metal is worth less per pound. Aluminium conducts at roughly six tenths of copper for the same cross-section, so equivalent ampacity needs a larger conductor, which changes which sizes sit in a lot.
The honest version of this conversation is short. We say what the material is, what it will be compared against, and that a copper-based expectation will not be met. Sellers who hear that before loading tend to send the material.
Corrosion, steel cores and what storage does
Bare aluminium forms a thin oxide immediately and that is protective. What damages it is the white powdery corrosion from sitting wet against another metal, and galvanic contact between aluminium strands and a steel core in a wet reel end. ACSR that has stood outdoors with an open end will show rust bleeding out of the core at the cut.
Insulated aluminium has its own storage problem. Water that enters a cut end travels under the insulation along the strands, and the conductor corrodes where nobody can see it. A reel with a sun-cracked jacket and open ends is worth less than the same reel stored under cover.
Where this cable turns up in the two states
Overhead aluminium is the dominant conductor in rural parts of both states. The electric cooperatives and Duke Energy string ACSR and AAC across the coastal plain and the Piedmont because spans are long and load is spread out, and every line rebuild leaves conductor on reels in a yard. Some of those reels have stood outside for a decade and the outer layers show every year of it.
Inside the fence, aluminium building wire turns up at the large end of industrial distribution, at Upstate automotive plants and Columbia manufacturers where the service is big enough for the weight saving to matter, and in the feeders of speculative warehouse construction along the interstate corridors. Solar collection systems on the coastal plain add another strand.

Aluminium wire and conductor questions
Is aluminium wire worth the same as copper?
No. It is a different metal with a different market, and value per pound reflects that rather than the price per foot of an equivalent ampacity. A reel of aluminium XHHW-2 doing the same job as a copper reel carries far less metal value. We will say what the material is rather than let a seller assume parity and be disappointed.
How can I tell AA-8000 from older aluminium wire?
The print on the insulation is the best evidence, and modern building wire usually states the alloy series. Age is the other clue: aluminium building wire from the 1960s and early 1970s predates the alloy requirement. Where the print is gone, the safe assumption is that it is not a listed building wire alloy, and it is reviewed on that basis.
Do you buy ACSR?
Yes, as conductor. We look at stranding, conductor diameter, the condition of the steel core and the length on the reel. ACSR that has been strung and recovered is a different review from new surplus, because the outer strands carry handling marks and the core may have started to corrode wherever the end was left open to weather.
What happens to aluminium terminations in a surplus lot?
They travel with the wire when they are still attached, and they are worth having, because a listed aluminium or dual-rated lug is part of what makes the conductor usable. Loose lugs of unknown rating are scrap. We separate the two rather than letting them disappear into the weight of the pallet.
