Muka Sublimation Aluminium Blanks 100pcs Small Circular Discs — 1″–3″ Assortment, 0.02″ White-Coated

Muka 100Pcs sublimation aluminium blanks are small, prepped circular metal discs made for heat-transfer images and DIY accessories.

These compact aluminium boards come in five popular diameters and a uniform 0.02-inch thickness, sold as a 100-piece assortment so crafters can produce consistent, durable photo-transfer projects. Each disc features a smooth, white-coated face ready for sublimation printing and a polished reverse suitable for adhesive mounting. They’re designed for hobbyists and small-business makers who want lightweight, printable components for keychains, pendants, badge reels and other personalised items.

What sizes are included and how thick are these blanks?

The set contains 100 circular aluminium blanks offered in five diameter options: 1", 1.5", 2", 2.5" and 3", all with a consistent 0.02" thickness. This selection covers the most common dimensions used for jewellery-style and small promotional products, allowing you to pick the best scale for each project.

• 100 pieces total across the five size choices
• Uniform 0.02-inch (approx. 0.5 mm) thickness for stability
• Multiple diameters fit pendants, keychains, and badge reels

How do I transfer an image onto the aluminium discs?

Prepare a sublimation print on transfer paper, align it on the coated face of the disc, then apply heat and pressure per your heat-press instructions. After cooling, remove the protective release film from the printed side; the reverse is ready for mounting with double-sided tape or epoxy.

• Use a sublimation printer and compatible inks with your standard temperature and time settings
• Peel off the front release film after pressing to reveal the finished image
• Attach with double-sided adhesive tape or a glue suited for metal backing

What projects suit these small aluminium boards?

These blanks are ideal for small-format, high-detail personalisation: custom keyrings, photo charms, zipper pulls, and badge inserts. Their light weight and printable face make them a natural choice for keepsakes, event giveaways, and small-batch merch.

• Keychains and pendants with full-colour photos or logos
• Phone stand insets, retractable badge faces, and jewellery accents
• Craft fairs and on-demand personalisation businesses

Are any extra supplies required to finish projects?

Yes — you’ll need sublimation ink, suitable transfer paper, and access to a heat press or mug/flat press. The package does not include double-sided tape or fasteners, so plan to buy adhesive mounting strips, jump rings, or keychain hardware separately.

• Double-sided tape or glue for mounting (sold separately)
• Sublimation-compatible printer, ink, and transfer paper
• Heat press or platen press set to recommended sublimation settings

Who is this for: Creators and small-business owners who offer personalised accessories, hobby crafters exploring sublimation, and event planners producing custom giveaway items. If you need consistent, small-format metal blanks ready for heat-transfer printing and easy mounting, this 100-piece Muka set provides a versatile, cost-effective stock of printable aluminium discs.
