ALCA5® cast precision plate's main advantage is its dimensional stability. The low level of internal stress, reduces considerably the possibilty of plate deformation during and after machining. This high stability leads to some cost savings by avoiding extra operations such as rough-milling, finishing or re-works. Typical applications are reference plates, molds, jigs, machine parts and construction equipments.
