G.AL® C330

Higher Strength Precision Milled Plate G.AL® C330

Alloy EN AW 7021 [AlZn5,5Mg1,5]
Type of Alloy heat-treatable
Temper solution heat treated, quenched, artifically aged, T79
Surface two surfaces precision milled, roughness Ra 0.4 µm, foiled on both sides

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.

Special features

  • Very high strength
  • Very uniform flatness
  • Very good machinability

Applications

G.AL C330 höherfeste Präzisionsgussplatten für Anwendungen im Werkzeugbau

Toolmaking

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.

G.AL C330 höherfeste Präzisionsgussplatten für Anwendungen in der Montagetechnik

Installation technology

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.

G.AL C330 precision machined aluminium cast plate for applications of the printing industry

Printing industry

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.

G.AL C330 precision machined aluminium cast plate for applications in automation technology

Automation technology

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.

G.AL C330 höherfeste Präzisionsgussplatten für Anwendungen in der Handlings-und Robotertechnik

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.

G.AL C330 precision machined aluminium cast plate for applications in special machine engineering

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.

Expert tip

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.
