Why Choose 1060 Precision-Ground Aluminum Rod?
1060 is a 1xxx-series commercially pure aluminum; trace copper improves machinability. Its properties directly address pain points in low-voltage power distribution and EV slow-charging components.
Leading electrical & thermal performance (62% IACS, ~210 W/m·K), reducing temperature rise in high-current busbars and charging terminals.
Excellent formability and weldability—deep drawing, stamping, and TIG/MIG welding without cracking.
Low density (2.70 g/cm³), ≥48% lighter than copper, lowering transport and installation costs.
Uniform grain structure and consistent anodized appearance, suitable for visible parts.
Precision Control (for CNC & Swiss-type)
Accuracy up to 0.02 mm — compatible with guide-bushing mode on Swiss-type lathes.
Straightness < 0.2 mm/m — stable with no vibration above 8,000 rpm.
Double-end chamfer — smooth, jam-free automatic bar feeding.
Turned bar head — pre-turned OD to fit limited-capacity collets/chucks.
Coarse-grain ring < 0.5 mm — prevents white spots/snowflake banding.
Improved machinability — optimized microstructure promotes chip breaking and boosts yield.
Chemical Composition

Processing & Manufacturing
Centerless Grinding Parameters
- Wheel surface speed: 40–60 m/s (white fused alumina / SiC)
- Workpiece speed: 100–200 m/min
- Feed: 0.04–0.07 mm/rev
- Grinding depth: 0.01–0.05 mm per pass; light, stepwise grinding to prevent burn
- Coolant: water-based emulsion + 2% oil; optional nano TiO₂ additive to reduce friction
Turning & Milling (1060 Aluminum Machining Data)
| Tool | Cutting speed (m/min) | Feed f (mm/rev) | Depth of cut ap (mm) | Recommended coating |
| HSS | 150–200 | 0.1 | 0.5 | — |
| Carbide | 250–350 | 0.15 | 1 | TiB₂ / DLC |
| DLC end mill | 350–500 | 0.05 per tooth | 1–3 | DLC |
Drilling: for Ø ≤ 10 mm use 40 m/min; for Ø ≥ 10 mm reduce to 20 m/min. Use a 135° point and evacuate chips regularly.
Surface Finishing
- Anodizing: current density 1.2 A/dm², film thickness 15 µm; bright silver or black anodize with high reflectivity.
- Mirror polishing: Ra < 0.2 µm, suitable for LED reflectors.
Typical Applications
EV charging infrastructure
Parts: charging handle/housing, charging terminals
Value: 62% IACS conductivity lowers contact resistance & temperature rise; good outdoor corrosion resistance
EV slow-charging systems
Parts: harness/busbars
Value: ≥ 48% weight reduction vs. copper, excellent formability & cost performance
Low-voltage power distribution
Parts: busbars, connector tabs
Value: adequate conductivity for low-voltage duty; lower hardness eases stamping to improve assembly efficiency
For scenarios requiring higher strength or fast-charging conditions, consider heat-treatable alloys such as 6061-T6 or 6101-T6. For low-voltage, slow-charging, and terminal components, 1060 remains a first choice thanks to its high conductivity, machinability, and low cost.
Frequently Asked Questions (FAQ)
Q: What are the differences among 1060, 1050, and 1070? A: Their minimum aluminum contents are 99.5%, 99.6%, and 99.7%, respectively. Higher purity yields higher electrical conductivity but slightly lower strength.
Q: Can 1060 precision-ground aluminum rods be used long-term in seawater? A: Yes. They have lower susceptibility to chloride-ion pitting than Al–Cu alloys and can be used directly in seawater heat-exchangers; anodizing with pore sealing is recommended to further enhance corrosion resistance.
Q: Can you provide SGS / RoHS / REACH documentation? A: Each batch ships with a COA. Upon request, we can arrange third-party testing by SGS, TÜV, or BV, and provide RoHS/REACH compliance statements.
Q: Can you deliver CNC-finished parts? A: Chalco offers one-stop services—cutting, drilling, mill-turn machining, and anodizing—for turnkey delivery.
