Magnesium Extruded Parts

Magnesium Extruded Parts


During extrusion, a manufacturer compels metal to pass through an open cross-sectional die and assume the shape of the die cavity. Many companies produce metal tubes, bars, pipes, molding and rebar using this production method. Extrusions occur using either hot, warmed or cold metal and metal alloys. The manufacturer may produce extrusions intermittently or continuously along an assembly line. The most widely extruded metals include aluminum, brass, tin, copper and steel. Magnesium is used in some aluminum alloys.


Magnesium Extrusion Process

Today researchers around the world strive to develop a commercially viable process for hot magnesium alloy extrusion containing high percentages of magnesium. This process usually occurs at the comparatively low temperature of 650 to 850 degrees Fahrenheit. A few manufacturers reportedly extrude some magnesium alloys for use in specialized components.

Many physical properties of magnesium closely resemble aluminum: this malleable metal offers light weight, coupled with strength and good corrosion resistance. Magnesium also supplies ductility and an attractive silvery-white color. However, magnesium will burn readily, emitting a brilliant white light; while manufacturers do indeed hot work magnesium alloys, these metals require careful handling to cast, weld and form.

Manufacturers have implemented automated machinery to permit the successful cutting and cold stretching of heat treated magnesium extrusions following die casting. The use of lasers facilitates the cutting of high percentage magnesium alloys to generate uniform parts. Additionally, some manufacturers report successfully utilizing rotary frictional forces to help weld magnesium powders and/or fragments. Manufacturers have witnessed marked improvements in the tolerances of extruded magnesium alloys produced using these methods.


Applications For Magnesium Extrusions

While many potential uses exist in the commercial marketplace for this exciting technology, price factors have not yet resulted in the extensive adoption of powdered magnesium alloys in the general marketplace. The use of magnesium alloys remains a rich topic for metallurgical research and development.

Meanwhile, research continues into the feasibility of high percentage magnesium alloys for use in hot extruded manufacturing processes. Progress has occurred recently in the area of cold magnesium extrusion, allowing the production of some high magnesium content parts. Potentially, a host of applications exist for these alloys in industries as varied as aerospace, defense, agriculture, biomedical science, transportation, heavy industry, and consumer goods. However, hot working magnesium still holds many challenges for manufacturing enterprises engaged in high volume production.


Custom Magnesium Extruded Parts

The development of custom magnesium alloy extruded parts offers the prospect of lightweight, very strong mechanical assembly components. While the field of magnesium extrusions at this point still possesses enormous growth potential, researchers continue to propose new ways to generate magnesium alloy extrusions in order to create in-demand custom parts for a variety of industries. Custom magnesium extruded parts would contain a higher percentage of magnesium than cast components, offering great strength coupled with light weight.

Extruded Magnesium Rod

An extruded magnesium rod permits the generation of many useful products for the consumer marketplace. From the development of very lightweight automotive parts to the creation tough corrosion resistant outdoor furniture, the commercial marketplace holds numerous potential applications for competitively priced extruded magnesium alloy rods.

Extruded Magnesium Cylinder

Today strong hot aluminum alloy extrusions contain magnesium. Engineers would surely find many uses for hot extruded magnesium alloy cylinders with higher magnesium percentage levels, since these alloys would offer the advantages of lighter weight and potentially even better corrosion resistance than comparable aluminum items. Research in this field continues to generate widespread interest. Comparatively recently, cold extruded magnesium has reportedly found applications in some high tech industries.

Extruded Magnesium Tube

Recently the development of cold extrusion technology reportedly allowed the generation of some magnesium tubes for use in industries such as computerized weaving machines. When hot extruded magnesium tubes containing high percentages of magnesium become more widely available in the commercial marketplace, we anticipate this development will interest many of BuntyLLC’s customers.
