Haomei Aluminum supplies 1060 aluminum strip and coil for pharmaceutical vial-seal manufacturing. Material specifications can be defined by alloy temper, thickness, slit width, surface finish, coil core ID and packing requirements.
Our supply covers semi-finished aluminum material for downstream stamping, forming and closure conversion, rather than assembled vial seals or complete sterile closure systems.
For a broader overview of material options and selection, see our aluminum for pharmaceutical vial seals page.

1060 is a commercially pure aluminum grade with a minimum aluminum content of 99.6% under the applicable composition specification. It is considered for applications where material purity, ductility and forming behavior are important.
In vial-seal production, aluminum strip is converted into closure components through operations such as stamping, forming and subsequent finishing. The required temper and thickness depend on the cap design, tooling, forming depth, crimping requirements and production conditions.
Haomei supplies the aluminum stock used in these operations. For a wider range of bottle-cap materials, visit our Aluminum Closure Stock for Bottle Caps.

Surface Finish Options for 1060 Aluminum Vial-Seal Stock
Plain Mill Finish
Uncoated stock for customers who apply their own finish or require a mill-finish surface. Specify surface cleanliness and appearance limits, including any restrictions on residual rolling oil.
DOS Oil-Lubricated Finish
DOS oil provides lubrication to help control friction during forming. Agree on the lubricant specification and application level, particularly if the stock will be cleaned, printed or lacquered later.
Chromate Conversion Coating
Where a chromate conversion coating is specified, confirm the exact chemistry before ordering. Acceptance depends on customer requirements, the intended closure design and restrictions in the destination market; "chromate" alone is not a complete coating specification.
Colored Lacquer on One Side
A colored lacquer on one face, paired with a clear protective lacquer or another agreed finish on the reverse. Gold, white, red, blue and black may be available. Confirm the shade, gloss and forming requirements against an approved sample.
Clear Lacquer on Both Sides
Clear lacquer covers both faces while retaining the metallic appearance of the aluminum. Specify the coating system and required performance after forming, including adhesion and resistance to cracking.
Custom Surface Treatments
For anodizing or a finish not listed here, send Haomei the closure drawing and surface specification for review. Feasibility depends on the treatment, forming sequence and intended use; confirm availability before placing an order.
Vial Seals 1060 Aluminum Strip Properties
- Corrosion Resistance: Naturally resistant to oxidation and chemical degradation, which is critical to maintaining drug integrity
- Formability: Excellent ductility allows for deep drawing into complex seal shapes like flip-off or pull-off caps without cracking
- Sterilization Compatibility: Withstands autoclaving, gamma radiation, and mercuric chloride tests without compromising mechanical properties
- Non-toxic: Compliant with FDA and EU directives for contact with food, pharmaceuticals, and cosmetics
- High Purity: 1060 aluminum alloy contains more than 99.6% aluminum, ensuring extremely high purity. This high-purity aluminum offers excellent corrosion resistance and effectively resists chemical components in drugs, preventing contaminants from entering the vial and preserving the effectiveness and stability of the medication.
- Workability: 1060 aluminum alloy has good ductility, enabling consistent formability in high-speed stamping processes without cracking or tearing. This is especially advantageous for mass production of complex cap designs.

Slitting Quality Control for Vial-Seal Strip
We check slit vial-seal strip against the order specification before release. Inspection covers strip dimensions, slit edges, surface condition and coil winding, with batch identification checked against the shipment documents.
- Thickness and width: We measure strip thickness and slit width to verify compliance with the tolerances specified for your order.
- Slit edges and camber: We inspect edge condition and check burrs and camber against the specified acceptance limits.
- Surface condition: We inspect for scratches, stains and lubricant residues. For coated strip, we also check coating appearance against the approved surface requirements.
- Coil condition and packing dimensions: We check core inside diameter, coil dimensions, winding condition and net weight against the order requirements before packing.
- Batch identification and traceability: We verify that coil labels and the required shipment documents identify the alloy, temper, strip dimensions and batch reference.
Coil Packaging and Quality Checks for 1060 Aluminum Strip for Vial Seals
Haomei Aluminum prepares 1060 aluminum strip for vial seals with protective packaging and pre-shipment checks to help maintain coil condition during storage, handling and export transportation. Each shipment is packed and identified according to the confirmed order specifications and agreed delivery requirements.

FAQ – 1060 Aluminum Strip for Vial Seals
Which temper is suitable for vial-seal production?
O temper may be considered when high formability is required. The final choice depends on the closure geometry, forming operation, tooling and acceptance requirements. Other tempers should be evaluated against the specific application.
Can Haomei supply colored or lacquered aluminum strip?
Haomei can review specified surface-finish requirements, including colored lacquer and clear lacquer options. Please provide the required color, coated side, coating specification and downstream processing conditions for technical confirmation.
Can 1060 aluminum strip be supplied with custom slit widths?
Custom slit widths can be specified according to the required dimensions and confirmed production capability. The order should also define width tolerance, edge quality and any required camber or burr limits.
Is 1060 O temper always the best choice for vial seals?
No. O temper may be suitable for demanding forming operations, but another temper may provide a more appropriate balance between ductility and shell stiffness. The final selection should be based on the seal design and production requirements.
Can I specify different finishes on the two sides of the aluminum strip?
Yes. A two-side finish specification can be submitted for review, such as colored lacquer on the exterior and protective lacquer on the reverse. The coating system and supply feasibility must be confirmed before ordering.
What information is needed for an accurate quotation?
Please provide the alloy, temper, thickness, slit width, dimensional tolerances, surface finish for each side, coil inside diameter, maximum outside diameter or coil weight, order quantity and destination. A vial-seal drawing or existing material specification can also help clarify technical requirements.
