Working with 8030-H19
Is 8030 easy to machine?
Very soft and gummy — use sharp polished high-rake carbide, high speed and flood lubricant; rarely machined since the alloy is sold as rod, wire and cable.
Can 8030 be welded?
Readily joined by TIG/MIG (1100 or 4043 filler), friction and cold-pressure welding; in service, conductors are compression- or set-screw-terminated with AL/CU-rated connectors and joint compound rather than welded.
Can 8030 be formed, bent or molded?
Excellent drawability from continuously cast rod to fine wire with intermediate or final anneals; compacts and strands well with low spring-back in O/H2x tempers.
What surface finishes work on 8030?
Normally supplied bare or insulated (THHN/XHHW/XLPE); tin plating is used on lugs and terminations, anodizing is only fair because of Fe/Cu intermetallics.

8030-H19 is typically used for electrical building wire, conductor rod and cable. In short: creep-resistant conductor aluminum; 61.8% IACS building wire; very high formability, low strength.
What is the yield strength of 8030-H19?
8030-H19 has a typical yield strength of 150 MPa (21.8 ksi) and a tensile strength of 170 MPa (24.7 ksi) — weaker than 65% of aluminum grades. Strength varies by condition: see the 8 listed tempers.
Is 8030-H19 easy to machine?
Not especially — machinability is rated fair (38/100, worse than 84% of aluminum grades). Very soft and gummy — use sharp polished high-rake carbide, high speed and flood lubricant; rarely machined since the alloy is sold as rod, wire and cable.
Can 8030-H19 be welded?
Yes — weldability is rated excellent (85/100). Readily joined by TIG/MIG (1100 or 4043 filler), friction and cold-pressure welding; in service, conductors are compression- or set-screw-terminated with AL/CU-rated connectors and joint compound rather than welded.
What surface finishes work on 8030-H19?
Normally supplied bare or insulated (THHN/XHHW/XLPE); tin plating is used on lugs and terminations, anodizing is only fair because of Fe/Cu intermetallics.
Can 8030-H19 be formed, bent or molded?
Excellent drawability from continuously cast rod to fine wire with intermediate or final anneals; compacts and strands well with low spring-back in O/H2x tempers.
What is the maximum service temperature of 8030-H19?
8030-H19 is rated for continuous use to about 100°C (212 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 8030-O and 8030-H19?
O is the default condition — default for AA-8000 building wire and flexible cable: maximum elongation and conductivity, lowest connection creep. H19: as-drawn hard wire, used mainly as an intermediate stage or where maximum tensile is required before final anneal. Yield strength is 35 MPa in O versus 150 MPa in H19.
