This material produced from alloy EN AW 7021 (AlZn5.5Mg1.5) in a vertical continuous casting process closes the gap between medium and high-strength aluminium materials, the latter of which are often overqualified. G.AL® C330 is characterised by a very fine and homogenous structure, very low microporosity, excellent machinability and very high strength. G.AL® C330 is manufactured in material temper T79, which is reflected in the low-stress properties and dimensional stability unique in this strength class.
The excellent flatness of G.AL® C330 allows for inexpensive production of tool holders, the high level of hardness reduces abrasion and ensures a long lifetime of the components.
Base and ground plates often have a variety of openings and pockets, meaning the risk of component distortion when using rolling plates is high. The extremely low residual stresses of G.AL® C330 significantly minimises this risk.
Due to the good technical anodising and hard anodising properties, the use of high- or ultra-high-strength rolled plates prone to warping can be avoided with the use of G.AL® C330, even at higher loads.
Higher-stressed transfer plates, swivel devices, clamping devices, etc. can be quickly and conveniently implemented due to the high strength and narrow tolerances of G.AL® C330.
Handling and robotic technology
Whether for gripping, clamping, or holding devices in handling machines and industrial robots: the high strength, very good machinability and dimensional stability of G.AL® C330 enables fast production of even intricate components.
Mechanical engineering and special machine engineering
In this demanding segment, precision plate G.AL® C330 is used for centring, mounting and pressing devices because of the good wear characteristics, among others.
Higher-strength precision plate G.AL® C330 can be used in over 70% of all applications to replace high- or ultra-high-strength rolled plates, thus saving time and money. We are happy to advise you regarding replacement of rolled plates with our G.AL® products.
