6-4 Plate Titanium Foil (Light Tight)

6-4 Plate Titanium Foil (Light Tight) is engineered for use in aerospace thermal shielding, laser enclosures, and vacuum chambers requiring a high level of material integrity and consistency. Its high tensile strength, low density, and corrosion resistance make it suitable for structural applications in controlled environments. Commonly used in photonic systems, beamline experiments, and sensitive optical testing setups and laboratories, this foil maintains integrity under thermal and mechanical stress. This material supports precise outcomes in research fields demanding light-tight barriers and reliable material performance. It is also applied in cryogenic sensor housings and synchrotron beamline masking, where minimal outgassing and dimensional stability are essential
