Working with 8017-H14
Is 8017 easy to machine?
Soft and gummy — use polished high-rake carbide, high speed, flood coolant to avoid built-up edge; rarely machined since the alloy is sold as wire.
Can 8017 be welded?
Readily weldable by GTAW/GMAW with 1100 or 4043 filler and by resistance/compression welding; HAZ anneals to O-temper strength but conductivity is unaffected.
Can 8017 be formed, bent or molded?
Excellent cold drawability from continuous-cast rod down to fine wire; bends and compression-terminates without cracking in O/H2x tempers, interanneal for heavy reductions.
What surface finishes work on 8017?
Normally supplied bare or extruded-insulated; anodizing gives only a dull grey functional film; tin or nickel plating on lug contact surfaces prevents galvanic problems with copper hardware.

8017-H14 — frequently asked
What is 8017-H14 used for?
8017-H14 is typically used for electrical wire, cable conductors and bus bar. In short: 61 % IACS conductor alloy; stronger than 1350 wire; very high cold drawability.
What is the yield strength of 8017-H14?
8017-H14 has a typical yield strength of 115 MPa (16.7 ksi) and a tensile strength of 130 MPa (18.9 ksi) — weaker than 79% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 8017-H14 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 89% of aluminum grades). Soft and gummy — use polished high-rake carbide, high speed, flood coolant to avoid built-up edge; rarely machined since the alloy is sold as wire.
Can 8017-H14 be welded?
Yes — weldability is rated excellent (85/100). Readily weldable by GTAW/GMAW with 1100 or 4043 filler and by resistance/compression welding; HAZ anneals to O-temper strength but conductivity is unaffected.
What surface finishes work on 8017-H14?
Normally supplied bare or extruded-insulated; anodizing gives only a dull grey functional film; tin or nickel plating on lug contact surfaces prevents galvanic problems with copper hardware.
Can 8017-H14 be formed, bent or molded?
Excellent cold drawability from continuous-cast rod down to fine wire; bends and compression-terminates without cracking in O/H2x tempers, interanneal for heavy reductions.
What is the maximum service temperature of 8017-H14?
8017-H14 is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 8017-H12 and 8017-O?
H12 is the default condition — the standard stocked intermediate temper for AA-8000 building-wire and cable conductors — strength enough to handle and pull, still soft enough to compress-terminate. O: choose for maximum flexibility and highest conductivity, e.g. flexible building-wire conductors and terminations that must not relax. Yield strength is 95 MPa in H12 versus 35 MPa in O.
