Chemical Composition (ASTM B209)
For precision-slit 6061 aluminum strips, the chemical composition per ASTM B209 and EN 573-3 must ensure uniform hardness and edge quality throughout the slitting process. Since strips are produced by slitting wider coil stock, the composition must be homogeneous across the full coil width to guarantee consistent properties in every slit strand.
| Element | Min (%) | Max (%) |
|---|---|---|
| Silicon (Si) | 0.40 | 0.80 |
| Iron (Fe) | – | 0.70 |
| Copper (Cu) | 0.15 | 0.40 |
| Manganese (Mn) | – | 0.15 |
| Magnesium (Mg) | 0.80 | 1.20 |
| Chromium (Cr) | 0.04 | 0.35 |
| Zinc (Zn) | – | 0.25 |
| Titanium (Ti) | – | 0.15 |
| Others (each) | – | 0.05 |
| Aluminum (Al) | – | Remainder |
Composition notes for strips: Silicon and magnesium are controlled at the mid-range of specification to balance strength with slitting edge quality: too much Mg2Si precipitation can create edge hardening during slitting, causing micro-cracks. Iron content below 0.50% ensures clean slit edges without burr-inducing intermetallic particles. For strips intended for electronic and connector applications, copper is kept at the lower end (0.15-0.25%) to optimize electrical conductivity while maintaining adequate strength.
Mechanical Properties of 6061 Aluminum Strip
The mechanical properties of 6061 aluminum strips, tested per ASTM B209 and ASTM B557, are inherited from the parent coil and verified on slit samples. Strip mechanical properties are critical for stamping and forming applications where consistent yield strength ensures predictable spring-back behavior.
| Property | T6 Temper | T651 Temper | O Temper |
|---|---|---|---|
| Ultimate Tensile Strength (MPa) | 290 | 290 | 150 |
| Yield Strength (MPa) | 240 | 240 | 83 |
| Elongation in 50mm (%) | 10 | 12 | 18 |
| Hardness (Brinell) | 95 | 95 | 30 |
| Elastic Modulus (GPa) | 68.9 | 68.9 | 68.9 |
| Fatigue Strength (MPa) | 96 | 96 | 62 |
Strip-specific mechanical considerations:
- Spring-back control: In T6 temper, strips exhibit 5-8 degrees of spring-back per 90 degree bend. O temper strips show minimal spring-back (1-2 degrees), enabling precise formed shapes.
- Edge hardness: Slitting increases edge micro-hardness by 10-15 HB. For critical forming applications, edge-annealed strips can be supplied to restore uniform ductility at the edges.
- Camber tolerance: Precision slit strips achieve camber of less than 1mm per 1000mm length, essential for automated feeding in progressive stamping dies.

Frequently Asked Questions
What is the minimum width for 6061 aluminum strips?
HXM Aluminum can slit 6061 aluminum strips to a minimum width of 10mm. For widths below 20mm, precision slitting with +/-0.05mm tolerance is recommended. The minimum practical width depends on thickness: thinner strips (0.1-0.5mm) can be slit narrower than thicker strips (2-4mm).
What width tolerance can you achieve for aluminum strips?
Standard slitting tolerance is +/-0.1mm for most widths and thicknesses. Precision slitting tolerance of +/-0.05mm is available for critical applications. The achievable tolerance depends on strip thickness, width, and alloy temper. Contact us with your specific requirements for confirmation.
What is the difference between 6061 aluminum strip and coil?
Strip is a narrow-width product (typically under 500mm) slit from wider coil stock, while coil refers to full-width rolled product (up to 2000mm). Strips are produced by slitting coils to precise widths. See our 6061 aluminum coils page for full-width coil specifications.
Can 6061 aluminum strips be anodized?
Yes, 6061 aluminum strips have excellent anodizing response. We offer clear anodizing, colored anodizing (bronze, black, champagne), and hard anodizing in strip form. Anodizing thickness ranges from 5 to 25 microns. Anodized strips are commonly used for architectural trim and decorative applications.
What is spring-back and how does it affect strip forming?
Spring-back is the elastic recovery that occurs when bent strip returns partially toward its original shape after the forming force is removed. In 6061-T6 temper, strips exhibit 5-8 degrees of spring-back per 90 degree bend. In O temper, spring-back reduces to 1-2 degrees. For precision formed parts, we recommend O temper forming followed by heat treatment to T6, or compensating for spring-back in die design.
How are 6061 aluminum strips packaged?
Strips are supplied in coil form on ID cores (300mm, 400mm, 508mm, or 610mm) or as cut-to-length pieces. Coils are wrapped with moisture-proof material, secured with steel straps, and packed on pallets or in wooden cases for export. Each package is labeled with alloy, temper, dimensions, and heat number.
What is the difference between T4, T6, and T651 tempers?
T4 is solution heat-treated and naturally aged — provides good formability with moderate strength. T6 is solution heat-treated and artificially aged — offers maximum strength (290 MPa UTS). T651 is stress-relieved by stretching after solution treatment — provides the same strength as T6 but with improved dimensional stability for machining. Choose based on your mechanical performance and processing needs.
Can you provide custom sizes for 6061 aluminum strips?
Yes, we offer fully custom sizes — any thickness from 0.1mm to 4mm, any width from 10mm to 500mm, in coil or cut-to-length form. We also provide custom surface finishes, edge treatments, and packaging. Please contact us with your detailed specifications for a personalized quote.
Can I get 6061 aluminum strips with deburred edges?
Yes, all slit strips are mechanically deburred to remove sharp edges and burrs from the slitting process. This is essential for automated feeding applications and safety handling. Additional edge finishing options include rounded edges and chamfered edges for specialized requirements.
