The short-chip alloy EN AW-7075 at a glance

EN AW-7075 is mainly used in the aerospace industry for all types of semi-finished products as well as for voltage-compatible plates in mold making and stamping tools.

The properties of WL 3.4364 at a glance

  • Very high strength (core strength decreases from a thickness of 80mm)
  • Hardenable alloy – strength can be increased enormously through heat treatment (solution annealing and subsequent hot storage)
  • Very good machinability in hardened condition
  • Very high fatigue strength
  • High-strength surface suitable for structural etching
  • Excellent polishability

Restrictions for EN AW-7075

  • Low resistance to weathering as well as sea water
  • Not anodizable (exception: protective anodizing)
  • Not solderable and weldable (exception: resistance welding)

For constructions with desired high corrosion resistance and weldability, we can provide you with alternate materials such as EN AW-6061 – please contact us.

WL 3.4364 & more at robemetall – suitable aluminum alloy and semi-finished products for every design

The standard WL 3.4364 is recognized by both the German Federal Office of Defense Technology and the German Federal Office of Aviation. For your constructions we keep the aluminum alloy EN AW-7075 in stock in various delivery forms.

  • Aluminum blank
  • Aluminum sheet
  • Aluminum round blank
  • L-profile, U-profile, T-profile as well as angle section
  • WL 3.4364 round rods in all common diameters

We are also able to meet individual customer requirements at short notice, for example:

  • Aluminum plates in special cuts
  • Round rods manufactured according to your specifications (water jet cut or sawing)

With the help of the selected heat treatment, different temper states and thus different properties can be achieved for the aluminum alloy. At robemetall you can obtain the following T-stages:

  • EN AW-7075-T0 or WL 3.4364-T0
  • EN AW-7075-T6 resp. WL 3.4364-T6
  • EN AW-7075-T7351 resp. WL 3.4364-T7351
  • EN AW-7075-T73511 resp. WL 3.4364-T73511

In addition to the EN AW-7075 aluminum alloy, we also keep other alloys and semi-finished products in stock as sheets, plates as well as round rods. Thanks to our modern sawing center, we are able to supply you with these in any shape and dimension on request.
