ALT5083 aluminium cast blocks sawn plate product is produced by an excellent flatness
stability. By adopting and extended thermal heat treatment the material becomes
homogenized and thermally stress relieved. Offered in a extraordinary range of
sizes, which are readily available along with superior mechanical and physical
properties which add to further major advantages of using alt 5083.
