What Is 1070 Aluminum?
1070 aluminum is a commercially pure wrought aluminum grade containing at least 99.70% aluminum. Its main advantages are conductivity, corrosion resistance and formability.
It is a non-heat-treatable grade: strength is controlled principally through cold working and annealing, rather than precipitation-hardening treatments. Select it where these characteristics fit the component's requirements; high-load structural parts need a separate material assessment.
1070 Aluminum Product Forms and Ordering Details
| Product form | Information to specify | Critical purchasing checks |
|---|---|---|
| Sheet | Thickness × width × length; temper; quantity | Thickness tolerance, flatness, squareness and surface condition |
| Plate | Thickness × width × length; cutting requirements | Thickness variation, flatness and machining allowance |
| Coil | Thickness × width; inside diameter; maximum outside diameter; coil weight | Compatibility with the decoiler, winding condition and surface protection |
| Strip | Thickness × slit width; inside diameter; coil weight | Width tolerance, camber, burr limit and edge profile |
| Foil, bar or rod inquiry | Product form, dimensions, manufacturing route and application | Separate review of supply availability, temper and governing specification |
Dimensions may be submitted in millimeters or inches. State the controlling unit system and tolerance basis on the drawing or purchase specification.
Available size combinations depend on product form, temper, processing route and order quantity. Confirm these together when requesting a quotation.
Specify the Correct Grade and Product Standard
A complete order should identify both the material grade and the product specification. A chemical designation alone does not define dimensional tolerances, mechanical properties or inspection requirements.
| Reference | Role in the purchase specification |
|---|---|
| AA 1070 | Identifies the registered alloy composition |
| ASTM B209/B209M | A sheet and plate product specification; verify coverage of the requested alloy, temper and dimensions before specifying compliance |
| EN 573-3 | Defines chemical composition and product-form information for European wrought aluminum designations |
| EN 485 series | Addresses sheet, strip and plate requirements, including mechanical properties and dimensional tolerances |
| ASTM B221 / B221M | Applies to qualifying extruded products; it is not the specification for rolled sheet or coil |
1070 Aluminum Chemical Composition
| Element | Limit, wt.% |
|---|---|
| Aluminum, Al | ≥99.70 |
| Silicon, Si | ≤0.20 |
| Iron, Fe | ≤0.25 |
| Copper, Cu | ≤0.04 |
| Manganese, Mn | ≤0.03 |
| Magnesium, Mg | ≤0.03 |
| Zinc, Zn | ≤0.04 |
| Titanium, Ti | ≤0.03 |
| Vanadium, V | ≤0.05 |
| Other elements, each | ≤0.03 |
1070 and 1070A require separate identification. Although both have a minimum aluminum content of 99.70%, their registered impurity limits differ. For example, 1070A specifies Cu ≤0.03% and Zn ≤0.07%. Confirm the exact designation required by the drawing and inspection document before accepting a substitution.
Choosing the Right Temper
| Temper | Condition | Selection guidance |
|---|---|---|
| O | Annealed | A starting point for demanding forming operations; confirm the finished component's strength requirements |
| H12 | Strain-hardened, quarter-hard | Consider where some additional strength is required while retaining forming capability |
| H14 | Strain-hardened, half-hard | Consider for moderate forming requirements with higher strength than annealed material |
| H16 | Strain-hardened, three-quarter-hard | Check bend geometry and required elongation carefully |
| H18 | Strain-hardened, full-hard | Consider where strength within the 1070 grade is prioritized and forming is limited |
The temper definitions describe processing condition; they do not establish one universal tensile strength or elongation value for every thickness. alumeco.com
For bending or drawing applications, send the finished-part drawing, bend radius, material thickness and forming direction. For repeat production, agree on a sample evaluation when the forming operation is critical.
Mechanical Properties and Electrical Requirements
Define acceptance criteria against the ordered product, rather than using a broad property range covering several tempers.
| Property | What to agree before ordering |
|---|---|
| Tensile strength | Minimum/maximum values for the specified grade, temper and thickness |
| Yield strength | Applicable requirement and test basis |
| Elongation | Minimum value, specimen orientation and gauge length |
| Electrical conductivity | Required minimum, reference temperature, method and reporting units |
| Thickness and width | Nominal dimensions, tolerances and measurement method |
| Surface and edges | Permissible scratches, residual oil, burrs and other application-specific limits |
For electrical strip buyers: Include the minimum conductivity or maximum resistivity, edge requirements and allowable coil joints in your inquiry. These requirements should be agreed explicitly instead of being inferred from the alloy name.
Theoretical Weight for Purchasing Estimates
Using a nominal density of 2,700 kg/m³, theoretical flat-sheet weight can be estimated as:
Weight (kg) = Thickness (mm) × Width (m) × Length (m) × 2.70
For example, a nominal 1.0 × 1,000 × 2,000 mm sheet has a calculated weight of approximately 5.40 kg. This is a calculation example, not a stock-size declaration; actual shipment weight reflects dimensional variation and packing.
1070 vs 1050, 1060 and 1070A
| Grade | Minimum aluminum content | Procurement guidance |
|---|---|---|
| 1050 | 99.50% | Retain this designation when required by the approved specification |
| 1060 | 99.60% | Compare the complete requirements before proposing a change to 1070 |
| 1070 | 99.70% | Specify the required temper, product standard and functional properties |
| 1070A | 99.70% | Check its separate composition limits; do not assume automatic equivalence to 1070 |
The purity values distinguish these designations, but purity alone is not a complete acceptance specification. aluminum.org
If a project specifies a dedicated conductor grade or another approved alloy, submit the specification for review before requesting an alternative.
Processing and Surface Requirements
Dongmeng Group supports inquiries for the following processing options:
Cut-to-length: Sheets and blanks prepared to the required dimensions.
Coil slitting: Widths and coil configurations matched to the receiving production line.
Protective film: Surface protection selected for handling and subsequent processing.
Surface finishing: Polishing, anodizing or coating requirements reviewed against the intended use.
Drawing-based preparation: Cutting and machining requests evaluated with the part geometry and tolerance requirements.
For strip orders, define the required edge condition. If the material passes near insulation or other sensitive components, specify a measurable burr limit and edge profile.
For appearance-sensitive parts, provide an approved finish sample or measurable acceptance criteria. Terms such as "bright" or "scratch-free" should be clarified before production.
Application Guide
1070 can be considered for electrical conductors, transformer components, heat-transfer products and reflective applications, subject to the component specification.
| Application | Information that improves material selection |
|---|---|
| Transformer winding strip | Conductivity, thickness tolerance, burr limits, coil dimensions and joint allowance |
| Conductive components | Electrical requirements, section dimensions, connection design and mechanical loads |
| Heat-transfer parts | Geometry, joining process, surface condition and operating environment |
| Formed housings and covers | Draw depth, bend radius, surface requirements and temper |
| Reflectors and decorative parts | Finish sample, appearance limits and subsequent surface treatment |
| Chemical-contact components | Medium, concentration, temperature and equipment design requirements |
For chemical-contact or load-bearing components, material suitability should be assessed against the actual service conditions.

Frequently Asked Questions
1. Are 1070 and 1070A the same material?
They share the same minimum aluminum content but have different registered composition limits. Order the exact designation required by the drawing or specification. Any proposed substitution should be reviewed before purchase.
2. Which temper should I choose for forming?
O temper is a useful starting point for demanding forming operations. H12 or H14 may be considered where the part also needs additional strength. Final selection depends on thickness, geometry and the forming process.
3. What dimensions can you supply?
Send the required thickness, width and length, or the full coil configuration. We review the available combination of dimensions, temper, tolerances and quantity before confirming the quotation.
4. Is a particular electrical conductivity guaranteed by the 1070 designation?
State your required minimum conductivity or maximum resistivity separately. The acceptance value, reference temperature, test method and reporting requirement should be agreed for the ordered product.
5. Can 1070 aluminum be supplied in T6 temper?
1070 is not a precipitation-hardening alloy, so T6 is not an appropriate temper choice. If the drawing requires T6, check whether it specifies a different aluminum grade. Hydro
