Alloy Grades and Tempers

Aluminum is available in various chemical compositions called alloys. Each alloy behaves differently when subjected to the high heat and pressure of a sublimation press.

Alloy and Temper Specifications

Alloy Grade	Common Temper	Relative Strength	Formability	Typical Sublimation Product
Alloy 1050	H14 (Half Hard)	Low	Excellent	Pet tags, small luggage tags, business cards
Alloy 3003	H14 (Half Hard)	Medium	Good	Car vanity plates, standard indoor signs
Alloy 5052	H32 (Stabilized)	High	Fair	Heavy-duty industrial labels, marine signs

Evaluating Thickness Options for Different Uses

The thickness of your sublimation aluminum sheets is represented by the variable t. Selecting the correct thickness ensures your prints remain flat and rigid without adding unnecessary weight and shipping costs.

Ultra-Thin Sheets

These sheets range from t=0.22 mm to t=0.35 mm.

Because they are so thin, they heat up very quickly in a press, usually requiring only 40 seconds to 50 seconds of heating. They are highly flexible and can even be wrapped around slightly curved surfaces. These are standard for metal business cards, thin labels, and decorative box inserts.

Standard Thickness Sheets

These sheets range from t=0.45 mm to t=0.70 mm.

This is the standard range for the sublimation industry. These sheets are rigid enough to hang flat on walls but thin enough to cut easily with simple manual metal shears. This thickness is ideal for indoor promotional signs, standard office nameplates, and small-format photo prints.

Heavy-Duty Sheets

These sheets range from t=0.80 mm to t=1.15 mm.

These plates offer high structural integrity. They require longer pressing times—typically 70 seconds to 90 seconds—to allow the heat to penetrate the thicker metal. This thickness is used for car license plates, high-end photographic wall panels, and directories.

Structural Grade Boards

These boards range from t=1.50 mm to t=2.00 mm or thicker.

These are extremely stiff and heavy plates. They are designed for self-supporting outdoor signs and heavy machinery tags. They require professional CNC routing or laser cutting equipment to shape.

Thickness Selection Guide

Thickness (t)	Weight Class	Rigidity Class	Pressing Time (190∘C)	Common Print Products
0.22 mm−0.35 mm	Ultra Light	Low (Flexible)	40−50 seconds	Business cards, curved trim, trophy plates
0.45 mm−0.70 mm	Light	Moderate	50−70 seconds	Small signs, desk plates, indoor decorations
0.80 mm−1.15 mm	Medium	High	70−95 seconds	Custom license plates, photo panels, outdoor tags
1.50 mm−2.00 mm	Heavy	Extremely High	100−130 seconds	Large hanging signs, industrial panels

Different Product Types to Match Your Business

We offer sublimation aluminum sheets in many configurations. This variety helps you meet the demands of different retail and industrial markets.

Bulk Sheet Stocks

We supply full-size sheets, typically measuring 600 mm×1200 mm or 1200 mm×2400 mm.

If you own a workshop with metal shearing machines or a CNC router, buying bulk sheets is highly cost-effective. You can cut the exact sizes you need for each order, minimizing scrap material.

Pre-Cut Sublimation Blanks

If you want to save time and reduce labor costs, pre-cut blanks are the ideal choice.

These blanks are cut to standard commercial dimensions. They have perfectly straight edges and smooth, rounded corners that prevent injuries during shipping and handling.

Custom Cut-to-Size Blanks

If you have a unique product design, we can manufacture custom blanks to your exact specifications.

Using precision laser cutters and hydraulic punches, we can cut custom lengths (l), widths (w), and shapes. We can also add pre-drilled holes in any diameter, slots for mounting straps, or custom corner curves.

Common Mistakes When Choosing Sublimation Aluminum

Choosing Based Only on Price

Lower-cost products may have inconsistent coating quality.

Ignoring Surface Finish

Different finishes produce completely different visual effects.

Using Indoor Products Outdoors

Outdoor projects require stronger alloys and higher-quality coatings.

Choosing the Wrong Thickness

Very thin panels may bend during installation.

Ignoring Customer Expectations

Photo customers usually prefer gloss surfaces, while signage customers often prefer matte finishes.

Direct Comparisons: Making the Final Choice

To help you make your final purchasing decision, we have created side-by-side comparisons of key specifications.

Alloy Performance Comparison

When choosing your alloy, compare these crucial environmental and mechanical properties.

• Alloy 1050: Low strength, very high flexibility, excellent thermal conductivity, low relative cost. Best for indoor tags.
• Alloy 3003: Medium strength, good flexibility, good thermal conductivity, moderate relative cost. Best for street signs and license plates.
• Alloy 5052: High strength, low flexibility, moderate thermal conductivity, high relative cost. Best for industrial panels and marine environments.

Feature Comparison	Alloy 1050	Alloy 3003	Alloy 5052
Tensile Strength	105−145 MPa	140−180 MPa	210−260 MPa
Bending Ease	Very Easy	Moderate	Difficult (Requires tools)
Marine Salt Resistance	Good	Very Good	Outstanding
Relative Material Cost	Low (\)	Medium (\$$)	High (\$$$$)

Coating Grade Comparison: Indoor vs. Outdoor

The chemistry of the polyester coating determines how long your print will last under different lighting conditions.

• Standard Indoor Coating: Designed for maximum gloss and color vibrance. It is highly affordable but can fade within 6 to 12 months if exposed to direct sunlight. Use this for family photos, indoor awards, and office signs.
• Outdoor UV-Resistant Coating: Formulated with special chemical UV blockers. This coating protects the underlying ink from ultraviolet radiation, keeping colors vibrant for up to 3 to 5 years outdoors. Use this for exterior signs, parking boards, and vehicle license plates.

Performance Metric	Indoor Standard Coating	Outdoor UV-Resistant Coating
UV Resistance	Low	High
Color Depth	Maximum	Good
Gloss Level	Highly Glossy (≥90% reflection)	Semi-Glossy to Glossy (80%−85%)
Price Point	Budget-Friendly	Premium
Outdoor Lifespan	Less than 1 year	3−5 years (Varies by sunlight)

Key Factors to Keep in Mind When Ordering

Before you place an order with a manufacturer, pay close attention to these technical and quality standards.

Dimensional and Flatness Tolerances

During the manufacturing of aluminum sheets, cold rolling can introduce slight thickness variations.

Make sure your supplier guarantees a tight thickness tolerance, such as ±0.02 mm. If the sheet thickness varies too much across its surface, your heat press will not apply even pressure, resulting in faded or blurry areas on your print.

Similarly, the sheet must be completely flat. Any slight warp or curl will prevent proper contact with your transfer paper, causing “ghosting” defects.

PE Protective Film Quality

Sublimation coatings are delicate before they are heated. To prevent scratches, dirt, and fingerprints during handling and shipping, a high-quality polyethylene (PE) protective film must be applied to the coated side of the sheet.

• The film should adhere firmly to the edges so it does not peel off accidentally during cutting.
• It must peel off cleanly in one piece without leaving any sticky adhesive residue on the sublimation coating.
• Always ensure you remove this film immediately before printing.

Packaging for Safe Transit

Aluminum is a soft metal, and its corners can bend easily during shipping.

When ordering in bulk, ensure your supplier uses robust packaging. This includes thick cardboard corner protectors, moisture-resistant plastic wrapping, and heavy-duty wooden crates or pallets. Safe packaging ensures that every single sheet arrives in perfect, ready-to-print condition.
