Xi’an Yuechen Metal Products Co., Ltd. (XYMCO) is one of the fastest growing magnesium alloy materials manufacturer in China. Our expertise and state-of-the-art equipments are focused on high valued magnesium alloy materials including magnesium alloy plate, magnesium tooling plate, AZ31B-TP tooling plate, magnesium alloy sheet, Magnesium CNC engraving plate, Magnesium CNC engraving sheet, Forged magnesium block, Magnesium tooling sheet, Magnesium extrusion, Cast magnesium tooling plate, magnesium alloy rod, magnesium alloy billet, magnesium alloy bar, magnesium welding rod, magnesium welding wire, magnesium flat bar, magnesium alloy ingot, Mg-RE (magnesium rare earth) alloy ingot, MgLi (magnesium lithium alloy) alloys, etc.

Established in 1995, XYMCO started as a new comer of magnesium alloy materials, but now we are a leading manufacturer, stockiest and specialist in this field. At the beginning, XYMCO only process the production if order is with enough quantities, but now, with our big quantities stock of differing kinds of magnesium materials, we can process orders both large and small, and we are able to offer quality magnesium materials at a competitive price, just-on-time delivery and quality guarantee, as well as providing value-added services to meet our customers’ most demanding needs.

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.
