Aluminum Alloys and Temper States
Selecting the correct aluminum alloy and temper ensures proper structural strength, corrosion resistance, and flatness during heat press cycles.
Key Alloy Options
Alloy 3003
Aluminum 3003 is an aluminum-manganese alloy. It offers good mechanical strength, high corrosion resistance, and excellent surface smoothness. It remains flat during high-temperature printing, making it the most popular choice for metal sublimation blanks.
Alloy 5052
Aluminum 5052 contains magnesium. It provides higher tensile strength and extra resistance to saltwater corrosion. This alloy works best for heavy-duty mini license plates, outdoor signage, and marine applications.
Alloy 1050 / 1100
Aluminum 1050 and 1100 are pure aluminum alloys with high thermal conductivity and low cost. They are soft, easy to cut or stamp, and ideal for light indoor promotional items.
Temper Configurations
H14 Temper
Strain-hardened and half-hard. It provides good rigidity while maintaining basic ductility for mild shaping or corner rounding.
H24 Temper
Strain-hardened and partially annealed. It balances strength and flexibility, helping prevent sheet bending during heat sublimation.
H32 Temper
Strain-hardened and stabilized. Standard for 5052 alloy, providing long-term structural stability under variable temperatures.
Alloy and Temper Comparison Table
| Alloy Grade | Tensile Strength (MPa) | Corrosion Resistance | Formability | Best Used For |
|---|---|---|---|---|
| 3003-H14 | 140−180 | Very High | Excellent | Indoor/outdoor photo plates, signs |
| 5052-H32 | 210−260 | Superior (Marine) | Good | Mini license plates, outdoor plaques |
| 1100-H14 | 110−145 | High | Superior | Low-cost crafts, indoor nameplates |
Surface Coatings and Coating Finishes
The sublimation coating layer determines color brightness, gloss level, and image sharpness.
White Gloss Coating
The white gloss coating has high light reflection and vivid color output. The opaque white base layer yields accurate skin tones and bright graphics.
White Matte Coating
The matte coating reduces surface reflection and glare. It provides a non-reflective finish suitable for indoor signage, office wall labels, and vintage photo prints.
Clear Metallic Silver Coating
The clear coating reveals the natural brushed metal surface beneath the ink. Transparent sublimation inks allow the metallic grain to show through, creating a unique metallic shimmer.
Coating Spec Summary Table
| Finish Style | Reflection Level | Color Reproduction | Best Printing Application |
|---|---|---|---|
| White High Gloss | High (>85% Gloss) | Maximum contrast and saturation | High-resolution photography, logos |
| White Matte | Low (<15% Gloss) | Soft tone, glare-free | Office signs, indoor art panels |
| Clear Metallic | Medium/Metallic | Semi-transparent metallic finish | Modern metallic art, specialty badges |

Frequently Asked Questions
What heat press temperature works best for a 4″×8″ aluminum blank?
The standard temperature setting is 385∘F to 400∘F (196∘C to 204∘C). Thinner blanks (0.020″) heat faster and need around 50 seconds, while thicker blanks (0.040″) require 75−85 seconds.
Why choose 3003 alloy over 1100 alloy for metal sublimation blanks?
Alloy 3003 contains added manganese, which offers greater tensile strength and structural rigidity. It stays flat during high-heat pressing, whereas pure 1100 aluminum can soften and bend under heavy pressure.
Do these aluminum blanks come with a protective film on both sides?
Single-sided coated blanks feature a protective film on the printable side. Double-sided coated blanks include protective films on both sides to preserve both printable surfaces during shipping.
Can I drill extra holes or trim these blanks after printing?
Yes. Aluminum alloys such as 3003 and 1100 are easy to cut and drill. Use standard metal drill bits or corner rounder punches without cracking the transfer coating.
What is the difference between white gloss and clear metallic aluminum sheets?
White gloss blanks have a solid white base layer under the coating for vivid, color-accurate prints. Clear metallic sheets omit the white layer, allowing the raw metallic aluminum grain to shine through the ink.
How do I prevent warpage when heat pressing thin metal sheets?
Use medium pressure (40 PSI) and ensure even heat distribution across the press platter. After pressing, place the hot sheet under a flat heavy object while it cools down.
