1050 Aluminum Disk

1050 Aluminum Disk is manufactured from a high-purity aluminum alloy (99.5% Al) with excellent electrical conductivity (~59% IACS), corrosion resistance, and superior cold formability. Its low-to-moderate strength (typical UTS ~105 MPa) is offset by exceptional elongation and thermal stability, particularly in cryogenic environments. Primary applications include electrical conductors, food-processing vessels, lighting reflectors, and thermal shielding components. Specific use cases range from cryogenic container linings to deformable calibration plates and corrosion test substrates. Research shows 1050 aluminum exhibits increased ductility and tensile strength as temperature decreases, making it ideal for precision environments like liquefied gas storage and superconducting test beds. With its high purity and reliable thermal response, 1050 disks are a critical material in thermal management studies, cryo-mechanical evaluations, and process control for aluminum-based systems.
