1050, 1050A, 1060, 1070 Photopolymer Plate Aluminum Substrates

1-Series photopolymer plate aluminum substrates are made from 1050, 1050A, 1060, and 1070 aluminum sheets as the supporting material for photopolymer plates (such as PS plates and CTP plates). These substrates provide the necessary mechanical strength and physical stability to ensure that the plate does not deform or shift during the printing process. Aluminum substrates have high aluminum content, excellent corrosion resistance, and good machinability.

Aluminum Substrate Material:

1050, 1060, and 1070 are industrial pure aluminum (aluminum content ≥ 99.5%), characterized by high ductility, low impurity content (Fe/Si ≤ 0.4%), and excellent chemical corrosion resistance, making them suitable for photopolymer plates (PS/CTP) as substrates.

These substrates are often used in the H18 cold-rolled hardened state (tensile strength ≥ 120MPa), balancing strength and surface flatness (tolerance ≤ ±0.005mm).

Performance Advantages of Photopolymer Plate Substrates:

1.Corrosion Resistance: Aluminum naturally resists corrosion, and after anodizing, it forms an oxide layer that extends the service life, reduces replacement frequency, and lowers production costs.

2.Thermal Conductivity: Excellent heat conduction prevents heat buildup, ensuring print quality. Suitable for hot stamping and high-temperature printing.

3.Mechanical Strength & Stability: High strength of aluminum alloys ensures resistance to deformation under pressure, maintaining stability during high-strength printing processes.

4.Smooth Surface: Precision machining results in a smooth surface that ensures even coating of the photopolymer material, improving print image quality.

5.Light Weight & Easy to Process: Aluminum is lightweight, making it easy to install, transport, and fabricate into complex shapes to meet the needs of different printing machines.

6.Environmental Friendliness: Aluminum is recyclable, reducing environmental pollution, and meets sustainable development standards. Additionally, fewer harmful substances are generated during the printing process.

7.Improved Photopolymer Effect: The anodized aluminum surface is smooth, enhancing the adhesion of the photopolymer material and ensuring high-quality exposure patterns.

8.Lower Production Costs: Aluminum substrates are relatively inexpensive, easy to process, suitable for large-scale production, and reduce plate-making and transportation costs.

9.Long-Term Stable Printing Effect: Aluminum substrates are not easily affected by temperature or humidity, ensuring stable print quality over extended periods, making them ideal for high-volume production.

10.Recyclable: Aluminum substrates have a recycling rate of ≥95%, meeting green printing standards and reducing waste pollution.
