What is 8177?
8177 is an Al-Fe-Ni conductor alloy in the AA 8000-series family (A98177, AlFeNi), with iron and nickel added to improve creep resistance at mechanical connectors while retaining 61.8% IACS conductivity and 232 W/m·K thermal conductivity. It is supplied as continuously cast rod and drawn wire for insulated building wire and connector-terminated cable in F, O, H1x, H2x and H19 tempers. Strength is low (38 MPa yield, 95 MPa tensile, HB 23) and the listed service ceiling is 90 °C, matching insulated wire ratings rather than structural use. 8030 is the closest alternative in the same conductor group. 8177 has a density of 2.71 g/cm³ (0.0979 lb/in³), heavier than 51% of aluminum grades. It melts at 645°C (1,193 °F). 8177 has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 95 MPa (13.8 ksi) — weaker than 96% of aluminum grades. Elongation at break is 28% and the elastic modulus is 69 GPa (10 Msi).

Working with 8177
Is 8177 easy to machine?
Soft and gummy — use sharp polished high-rake carbide, high speed and flood coolant; rarely machined since product form is wire.
Can 8177 be welded?
Readily joined by resistance/friction and by GTAW with 1100 or 4043 filler, but electrical joints are normally made by compression or AL-rated mechanical connectors rather than welding.
Can 8177 be formed, bent or molded?
Excellent cold drawability from continuous-cast rod down to fine wire; interanneal to restore ductility, and use O/H2x tempers where tight bending in junction boxes is required.

What surface finishes work on 8177?
Usually left bare under extruded PVC/XLPE insulation; if bare, oxide film gives adequate protection — anodizing is possible but Fe constituents give a grey tone, and copper-to-aluminium terminations need plated connectors plus oxide-inhibiting compound.

8177 — frequently asked
What is 8177 used for?
8177 is typically used for insulated electrical wire, connector-terminated cable and building wire. In short: creep-resistant conductor alloy; 61.8% IACS with 232 W/m·K; wire-only product form.
What is the yield strength of 8177?
8177 has a typical yield strength of 38 MPa (5.51 ksi) and a tensile strength of 95 MPa (13.8 ksi) — weaker than 96% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 8177 easy to machine?
Not especially — machinability is rated poor (28/100, worse than 94% of aluminum grades). Soft and gummy — use sharp polished high-rake carbide, high speed and flood coolant; rarely machined since product form is wire.
Can 8177 be welded?
Yes — weldability is rated very good (80/100). Readily joined by resistance/friction and by GTAW with 1100 or 4043 filler, but electrical joints are normally made by compression or AL-rated mechanical connectors rather than welding.
What surface finishes work on 8177?

Can 8177 be formed, bent or molded?
Excellent cold drawability from continuous-cast rod down to fine wire; interanneal to restore ductility, and use O/H2x tempers where tight bending in junction boxes is required.
What is the maximum service temperature of 8177?
8177 is rated for continuous use to about 90°C (194 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 8177-O and 8177-H19?
O is the default condition — standard condition for flexible building-wire conductor and stranded cable requiring easy bending and stable connector performance. H19: fully cold-drawn hard wire for stranded conductors and where maximum tensile strength is needed before final annealing. Yield strength is 38 MPa in O versus 160 MPa in H19.
