A hexagon bar that measures 0.1 mm over on the across-flats dimension will not seat in the nut it was meant to drive, and a bar that misses its conductivity spec lets a busbar run hot under full load. Those are the two failures that actually stop a production line - not the alloy's modest strength, which is expected for pure aluminum.

What is 1060 Aluminum Hexagonal Bar

1060 is a commercially pure wrought aluminum in the 1xxx series, with a minimum aluminum content of 99.6%. A hexagonal bar is a six-sided long product - most often extruded, sometimes cold-drawn - whose flat faces give a wrench a positive grip without the need for a separate nut blank. That shape makes it the natural starting stock for machined fasteners, wrench fittings, and any part that gets turned or milled on a hexagonal blank.

You choose 1060 when conductivity, corrosion resistance, and formability matter more than load-bearing strength. It carries about 62% IACS electrical conductivity, resists atmospheric and many chemical environments through its self-forming oxide film, and bends or stamps in the O temper without cracking. It is not a structural alloy - for beams or high-stress brackets you would move to 6061 or 5052. Because 1060 is non-heat-treatable, every bit of its strength comes from cold work, so the temper you pick sets both the strength and the remaining ductility.

Chemical Composition

Values follow the Aluminum Association composition limits for AA 1060. Lower residual content (Fe, Si, V) directly improves electrical conductivity and anodized appearance, which is why high-purity 1060 is preferred for busbar and decorative use over dirtier tempers.

Mechanical Properties

Typical values for extruded and cold-finished bar per the Aluminum Association designation system. Actual results vary with product form and temper and are reported on the mill test certificate for each lot. Yield is the 0.2% offset proof stress. H18 gives the highest strength but the least ductility, so it suits turned parts rather than formed ones; O gives the lowest strength and the best formability.

Physical & Thermal Properties

The 62% IACS volume conductivity is the reason 1060 appears in busbars and transformer windings: it moves current almost as well as copper by weight, at far lower mass and cost. The thermal conductivity close to 234 W/m·K also makes it a practical heat-sink and cooling-fin stock.

Heat Treatment & Temper Guide

1060 is non-heat-treatable. The solution-treatment-and-age cycle used for 6xxx alloys (around 530 °C solution plus an artificial age) does not apply and will not raise its strength. All strength comes from strain hardening - cold working after extrusion.

O (annealed): full anneal at roughly 343–413 °C (650–775 °F), air cooled. Maximum ductility for deep drawing and bending.

H12 (¼ hard): about 21% cold reduction. A small strength gain with most ductility kept.

H14 (½ hard): about 40% cold reduction. The common general-purpose temper for busbar and formed parts.

H16 (¾ hard): about 60% cold reduction. Higher strength, lower formability.

H18 (full hard): about 75% cold reduction. Highest strength, lowest elongation; best for turned fasteners.

H112: hot-worked or extruded condition, no special thermal cycle; used for bar and thick shapes.

In production the billet is extruded at roughly 480–540 °C, then drawn or rolled to the target temper. Hot working is practical in the 482–260 °C (900–500 °F) range. Because temper is set by deformation, not by furnace, the same chemistry can ship in any temper you specify.

Equivalent Designations

Use these cross-references when your purchaser specifies a national standard different from the one on our quotation. The underlying metal is identical; only the calling standard changes.

Corrosion Resistance

Atmospheric: Excellent. The surface oxide film repairs itself in air, so 1060 performs well in rural, urban, and most industrial atmospheres. Industrial sulfur exposure raises the rate slightly but stays serviceable for decades.

Marine: Good in open seawater spray and topside exposure. Pitting is possible in stagnant, trapped seawater, and 1060 is less resistant than the 5xxx marine alloys. Design for drainage and avoid crevices.

Galvanic: 1060 is anodic to copper, steel, and stainless steel. In an electrolyte it corrodes first, so isolate it with dielectric spacers or coat the joint when mating to nobler metals.

Stress-corrosion cracking (SCC): Not susceptible. Pure aluminum at low strength and high ductility does not show SCC in the environments where it is used.

With finish: Mill finish is adequate for most atmospheric and indoor uses. Anodizing adds a harder, more uniform, and more decorative surface that also improves wear and stain resistance.

Fabrication

Welding. 1060 welds readily by GTAW (TIG) and GMAW (MIG) with no pre- or post-heat. Use ER4043 filler for the best fluidity and the lowest hot-crack risk on pure aluminum, or ER5356 when you want slightly higher joint strength and a closer color match after anodizing. Remove the oxide layer mechanically or chemically before welding, and shield the root on open-root joints.

Machining. Fair. Pure aluminum is soft and tends to gum the tool, so use sharp high-speed-steel or carbide cutters, high surface speed, low feed, and generous rake angle. H14 and H18 machine more cleanly than O because the cold work raises hardness. Diamond-like (DLC) or TiB₂ coatings help chip breakage on production runs.

Formability. Excellent, especially in O temper. You can bend, stamp, and deep-draw 1060 without intermediate annealing for most operations, then select the final temper by the amount of cold work applied.

Surface Finishes

Anodizing takes well on 1060 because of its low alloy content, giving a cleaner, more uniform film than on the higher-alloy grades.

Applications

Electrical & power distribution - busbars, conductors, transformer windings, cable lugs. Why 1060: 62% IACS conductivity at about 48% of copper's weight lets you size up cross-section and cut mass and cost.

Fasteners & hardware - hex nuts, bolts, rivets, wrench fittings. Why 1060: the hex blank gives flats for tooling and machines cleanly in H14/H18.

Chemical processing - tanks, piping, lab apparatus. Why 1060: corrosion resistance and high purity keep process streams clean and non-contaminating.

Heat exchangers & cooling - fins, heat-sink bases, cooling plates. Why 1060: ~234 W/m·K thermal conductivity moves heat efficiently.

Architectural & decorative - trim, handles, nameplates. Why 1060: formability plus a uniform anodized surface.

Food & pharmaceutical equipment - frames, trays, housings. Why 1060: corrosion resistance, easy cleaning, and non-toxic surface.

Automotive & EV - charging terminals, low-voltage distribution busbars. Why 1060: light weight and conductivity suit high-current, weight-sensitive links.

General fabrication - brackets, welded frames, fixtures. Why 1060: weldable, formable, and low cost for non-structural parts.

Quality Inspection

Risk. A hex bar that drifts out of its flat-to-flat tolerance jams in the nut or the CNC collet, and a bar whose chemistry slips loses the conductivity and anodize quality you bought it for. Both failures show up only after the stock reaches your floor.

Action. Every lot is gauge-checked for across-flats, flat-to-flat, corner radius, and straightness against the ASTM B221 extruded-bar table, and the surface is inspected for seams, cracks, and deep scratches. One tensile sample per heat is pulled to verify UTS, yield, and elongation, and chemistry is confirmed by spectrometric analysis before the lot is released.

Standard. Dimensional control follows ASTM B221; each lot ships with an EN 10204 3.1 mill test certificate. Where conductivity is grade-critical, we check it against the 62% IACS typical so the busbar will not run hot.

Result. Any bar that fails flat-to-flat, chemistry, or tensile at final inspection is quarantined and replaced before packing. The MTC travels with the lot, so you can trace every dimension and property back to the heat and the gauge record.

1060 vs Other Aluminum Alloy Comparison

1060 leads this group on conductivity and sits at the low end on strength. Pick it when current-carrying or forming dominates; move to 3003 for more strength at modest cost, or to 6061/5052 when the part must carry structural load.

Other pure and low-alloy hexagon bar grades we cover include 1050, 1100, 3003, 5052, and 6061 - each carries its own specification page.

Why Choose GNEE

GNEE is an aluminum manufacturer with 18 years of export experience, supplying extruded and cold-finished bars to distributors, fabricators, and equipment builders across Asia, the Middle East, Europe, and the Americas.

Material traceability. Every lot ships with an EN 10204 3.1 mill test certificate recording chemistry, temper, and mechanical results, and we keep the heat and gauge records on file so a later claim can be checked against the original production batch.

Tempers and sizes on demand. We stock and produce 1060 hex bar from O through H18, across-flats 5–150 mm, in standard 1000–6000 mm lengths or cut to your dimension - so you are not forced into a stock size that wastes material.

Cutting and machining. Saw cutting, CNC turning, chamfering, and centerless grinding are done in-house, which shortens the supply chain between our bar and your finished part.

Export packing. Bars are packed seaworthy: wooden crate or pallet, edge protection, and a moisture barrier, so they arrive without corner damage or corrosion staining from transit.

Delivery you can plan around. After you confirm the drawing and temper, we schedule extrusion and cold-finishing, then inspect every lot against ASTM B221 and issue the MTC before packing. Standard lead time is 15–30 days; we flag any across-flats size outside our tool range at the quotation stage, so there are no surprises after order. If a lot fails flat-to-flat or conductivity at final inspection, it is quarantined and replaced at our cost - your shipment date does not move because of a non-conforming bar.

FAQ

Q1: Is 1060 aluminum hexagonal bar heat-treatable?
No. 1060 is non-heat-treatable; its strength comes only from cold work (H12–H18 tempers). We anneal to O when your part needs maximum formability, and cold-finish to H14 or H18 when you need strength for machining.

Q2: What filler wire should I use to weld 1060 hex bar?
Use ER4043 for the best fluidity and the lowest hot-crack risk on pure aluminum, or ER5356 when you want slightly higher joint strength and a closer anodized color match. Neither needs pre- or post-heat.

Q3: Can you supply a specific across-flats size not in your stock list?
Yes. We extrude and cold-draw to customer drawings. Send the across-flats, length, and tolerance, and we confirm tooling availability and lead time before you order.

Q4: What documentation comes with the order?
A mill test certificate (EN 10204 3.1) showing chemistry and mechanical results, plus we accept third-party inspection (SGS, BV, or your nominated surveyor) on request.

Q5: How does 1060 compare with copper for busbars?
1060 gives about 62% IACS conductivity at roughly half the density and a much lower material cost; you size the cross-section up to carry the same current. For distribution and EV links where weight and budget matter, that trade is usually worth taking.
