Magnesium Profile AZ31 / AZ31B magnesium extrusions / AZ31B-F profile Magnesium
The process for extruding magnesium wrought material is almost the
same as the process for extruding aluminium materials. Most common
is direct extrusion without a lubricant.
Cylindrical ingots are heated to 300-400 degrees Celsius (depending
on the used alloy) and pressed through dies with manifold cross-
sections. This procedure ensures a clean metallic surface and
non-porous microstructures that are really important for high-tech
materials and special requirements.
The maximum extrusion speed depends on the alloy that’s been used
and defines the price. The alloy AZ 31 is easier for extrusion, and
the most difficult alloys are for example AZ 80 and ZK 60 The
extrusion speed is sometimes more than ten times slower for these
alloys.
The special shapes and cross-sections of the magnesium extrusions
can be designed with considerable freedom. Extruded shapes are
separated into solid and hollow profiles according to the
complexity factors and the cross-sections. Full rods, flat bars and
shapes without embedded planes belong to the first type, while
hollow profiles include one or more completely enclosed cavity or
bay region.
The minimum wall thickness is determined by the alloy and form of
the profile. For small or medium size profiles in alloy AZ31 the
minimum wall thickness is about 1 mm. Wall thickness in multiple
walls with bosses, flanges, ribs, slits and indentations can be
incorporated into a new designed product to maximize the mechanical
properties.
With some of the alloys it’s possible to extrude magnesium on the
standard dies that are normally used for aluminium extrusions with
a small correction to the die. Because of this there is a wide
range of standard profiles (for example flat/angle/rectangular
–square and round tubes/ U-shape/H-shape etcetera) that can be
extruded without big investments in new dies. The second added
value for the customer is that for new designed profiles, he only
needs to invest in one single die for extruding profiles in
aluminium and magnesium.
After extrusion there are several steps necessary before the
extruded profile can be used for constructional components with the
required strength for example stretching and special heat
treatment.
XYCM’s capacity for the extrusion:
Bar: Max. Diameter: 300mm;
Tube: Max. OD: 600mm x thickness 125mm
Flat bar: 920 x 160mm
U-Shape: 800 x 300mm
Rectangular: 700 x 200mm
Square tube: 430 x 430mm
Max. Length for the above items: 30meter/each
We also can extrude special shape profiles according to customer’s drawings, and we have good machining capabilities.
Applications of our extruded products:
The special characteristics of magnesium such as its light weight
and damping capacity make it therefore, a material that is readily
used in several different applications.
