    Magnesium Profile AZ31 / AZ31B magnesium extrusions / AZ31B-F profile Magnesium

    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.
