ALT5083plus aluminium precision milled plate product is characterized by an excellent dimensional stability. By adopting and extended thermal heat treatment the material becomes homogenized and thermally stress relieved. This high stability leads to cost saving on extra operations such as rough-milling, finishing or re-works. Each plate is inspected for thickness, flatness, surface roughness and any other defects and finally covered with PVC foil for protection.
