1070 Aluminum Foil (Light Tight)

1070 Aluminum Foil (Light Tight) combines the ultra-high purity of 1070 aluminum with enhanced surface characteristics that block light penetration, making it ideal for applications requiring light shielding, thermal stability, and electrical integrity. The alloy’s fine-tuned composition and microstructure provide excellent corrosion resistance, mechanical flexibility, and tensile strength above 210 MPa, with elongation exceeding 2.5%. This makes it suitable for lithium-ion battery casings, aerospace fluid containment, protective shielding, and thermal packaging. It is especially effective in explosion-proof fuel systems, battery pouch laminates, and sensor housings where light exposure must be minimized. The foil’s grain-refined structure, resistance to pinholing, and low reflectivity are critical for vacuum environments, EMI shielding, and cryogenic applications. In research and innovation, it is deployed in photonic device isolation, dark-chamber sample protection, and radiation-sensitive material encapsulation. Its synthesis allows for both mechanical integrity and optical opacity, positioning it as a core material in high-tech and energy-critical environments.
