Aluminum sublimation sheets are widely used for photo printing, signage, decoration, gifts, and personalized products. These sheets have a special coating that allows images to transfer onto the aluminum surface through heat and pressure.
Among many thickness options, 1mm and 1.15mm aluminum sublimation sheets are two of the most popular choices.
Both thicknesses are suitable for high-definition printing, but they have different advantages in strength, flatness, durability, and application.
Choosing the right thickness can help improve print quality and reduce production cost.
What Is an Aluminum Sublimation Sheet?
An aluminum sublimation sheet is a coated aluminum panel designed for dye sublimation printing.
The image is transferred onto the coated surface using:
- Sublimation ink
- Transfer paper
- Heat press machine
The final image becomes part of the coating layer instead of sitting on the surface.
Main Features
| Feature | Description |
|---|---|
| Lightweight | Easy to handle |
| Waterproof | Good moisture resistance |
| Bright Surface | High image clarity |
| Long Life | Fade-resistant |
| Smooth Finish | Professional appearance |
Difference Between 1mm and 1.15mm Aluminum Sublimation Sheets
The main difference is thickness, but thickness also affects rigidity, weight, durability, and installation.
Basic Thickness Comparison
| Specification | 1mm Sheet | 1.15mm Sheet |

Comparison of Technical Specifications
Before you buy, you should compare the physical numbers. This helps you understand what you are paying for.
| Feature | 1mm Aluminum Sheets | 1.15mm Aluminum Sheets |
|---|---|---|
| Thickness | 1.0mm (0.040″) | 1.15mm (0.045″) |
| Weight | Lighter (2.7kg/m2) | Heavier (3.1kg/m2) |
| Rigidity | Moderate (Flexible) | High (Very Stiff) |
| Heat Absorption | Heats up quickly | Takes longer to heat |
| Price Point | Economy / Mid-range | Premium / High-end |
| Edge Finish | Sharp / Standard | Usually Rounded / Smooth |
Alloy Types and Metal States
The type of aluminum used inside the sheet matters just as much as the coating. Most manufacturers use the 1000 or 3003 series.
1000 Series (Pure Aluminum)
Alloys like 1050 or 1100 are almost pure aluminum. They are very soft. These are often used for 1mm aluminum sublimation sheets because they are easy to cut into small shapes like keychains or business cards.
3003 Series (Manganese Alloy)
The 3003 alloy is stronger. It contains manganese. This is the preferred choice for 1.15mm aluminum sublimation sheets. The added strength prevents the metal from warping (bending) when it is inside the hot heat press.
Temper and State
The state of the metal is usually H14 or H18.
- H14 (Half-hard): This is the best balance. It is stiff enough to stay flat but not so brittle that it cracks.
- H18 (Full-hard): This is very stiff. It is used for large wall panels that must stay perfectly flat over long periods.
Coating Types and Surface Finishes
The coating is the most important part of sublimation metal blanks. Without a good coating, the colors will look dull.
| Finish Type | Visual Look | Best Use |
|---|---|---|
| White Gloss | Bright, Shiny, Vivid | Professional Photography |
| White Matte | Soft, No Reflection | Portraits, Art Gallery Displays |
| Clear/Silver Gloss | Metallic, See-through | Black and White Photos, Tech Signs |
| Brushed Silver | Textured, Industrial | Modern Office Signage, Trophies |
| Gold Gloss | Luxury, Yellow-tone | Awards, Wedding Invitations |
Why Choose 1mm Aluminum Sublimation Sheets?
1mm aluminum sublimation sheets are excellent for specific projects. They are the “workhorse” of the small gift industry.
- Lightweight: Because they are thinner, they are cheaper to ship. This is great for e-commerce sellers.
- Easy to Fabricate: You can cut them more easily with standard metal shears or small CNC machines.
- Fast Production: They reach the required sublimation temperature faster than thicker plates. This saves time in the workshop.
Why Choose 1.15mm Aluminum Sublimation Sheets?
If you are selling to professional photographers or interior designers, 1.15mm aluminum sublimation sheets are the best choice.
- Premium Feel: The extra thickness makes the product feel expensive and high-quality in the customer’s hand.
- Warpage Resistance: When you heat a metal plate to 200 degrees Celsius, it wants to bend. The 1.15mm thickness resists this better than thinner sheets.
- Durability: They are much harder to dent or bend during shipping or when hanging on a wall.
Application Fields for Sublimation Metal Blanks
Professional Photo Panels
This is the biggest market for 1.15mm aluminum sublimation sheets. High-end landscape and wedding photos look amazing on these panels. They provide a “3D” depth that paper cannot match.
Awards and Trophies
Custom trophies often use 1mm aluminum sublimation sheets. They are easy to mount onto wooden bases. They provide a shiny, metallic finish for “Employee of the Month” or sports awards.
Signage and Branding
Office signs, nameplates, and direction signs use both thicknesses.
- 1mm is used for indoor door signs.
- 1.15mm is used for larger wall-mounted branding in lobbies.
Personalized Gifts
- Keychains: Usually thinner (0.5mm to 1mm).
- Business Cards: Metal business cards are usually very thin (0.2mm to 0.5mm).
- License Plates: These usually require 1mm thickness for durability on the car.
Heat Press Settings for Different Thicknesses
When you switch between 1mm vs 1.15mm, you must adjust your machine.
- For 1mm Sheets: Usually, you press at 190−200 degrees Celsius (375−400 °F) for about 60 seconds.
- For 1.15mm Sheets: You may need to increase the time to 75−90 seconds. The thicker metal acts like a “heat sink” and takes longer to reach the temperature where the ink turns into gas.
Product Types by Dimension
