Extruded Shapes

extruded magnesium shapes
Mag Specialties has experience extruding over 9000 shapes in over 20 different magnesium alloys. We offer magnesium extrusions in a variety of standard alloys and forms as well as many special shapes tailored to fit a customer's requirement.

Typical benefits of magnesium extruded products include:
Lightest Structural Metal
Extruded magnesium is the lightest structural metal weighing 33% lighter than aluminum
High specific strength and stiffness
Magnesium extrusions are up to 25% lighter than aluminum on an equal strength or stiffness basis
Superior Machineability
Magnesium requires 45% less power to machine than aluminum
Complex shapes and tight tolerances
Magnesium can be extruded into complex shapes with tight tolerances
High shock absorption and dent resistance
Magnesium is ideal for applications requiring shock absorption and dent resistance
Good thermal conductivity and thermal stability
Extruded magnesium conducts heat well and has good thermal stability
Low tooling cost
Extrusions have low tooling cost and allow fast prototype development

Extruded Anodes

extruded anodes
The use of extruded anodes for cathodic protection of residential and commercial glass-lined water heaters is a common practice. Mag Specialties supplies customers with both magnesium and aluminum anodes. Our magnesium anodes consist of our standard Galvorod™ (AZ31B) for regular application or Galvomag™ (M1C) for high-current output applications. Both magnesium and aluminum anodes (A420 & A8020) can be supplied in a variety of sizes and finishes.

Some of the benefits of our anodes are listed below:
Guaranteed highest quality
We supply the highest quality anodes verified by independent labs
High anode efficiency
Extruded anodes typically have a 54% anode efficiency or higher per ASTM G97 test ensuring they will last over extended periods of time
NSF/ANSI 61 Certification
MAG is NSF/ANSI 61 certified, ensuring our anodes have been tested for trace elements that may be harmful
Our Galvoline™ product line, also an M1C alloy, is primarily used for underground applications with high current output requirements. Galvoline™, unlike individual anodes, produces an efficient and even current distribution along a pipeline. This product line is typically sold in coils and delivered on pallets.

Cast Anodes

magnesium cast anodes
Mag Specialties provides the cathodic protection industry with high quality cast anodes in both Galvomag™ (M1C) and H1 (AZ63-B). Our Galvomag™ alloy is typically used in applications that require a higher current output. We provide D-Type, S-Type and Aqueous Series cast anodes. All our cast anode grades are tested by independent labs to meet or exceed 50% current efficiency per ASTM G97 test.


magnesium concrete tool
Mag Specialties produces concrete tool magnesium extrusions for some of the largest concrete tool manufacturers in North America. Since we don’t produce finished concrete tools, we leave that task for our valued customers. We’ve supplied some of these companies for over 30 years and we value the relationships that have been developed with our company. Some of the extrusions we produce are:
Magnesium Bullboats
Magnesium Screeds
Magnesium Handfloats
Magnesium Channel floats
Magnesium Lutes

Extrusion Benefits

Magnesium concrete tools are 33% lighter than aluminum
Magnesium is alkali resistant and lasts longer than aluminum, and is more durable than wood
dimentional tolerance
Magnesium concrete tools have excellent dimensional tolerance – especially flatness
A Better finish
Magnesium concrete tools typically give a better surface finish on concrete
Mag Specialties is a North American producer providing shorter delivery lead-times

Forging Billets

magnesium forging billets
Mag Specialties produces the highest quality magnesium forging billets in our industry. Leveraging our long history in magnesium production, we’ve developed a process to produce magnesium forging stock that meets the stringent requirements of our customers. The use of our forging billets in the production of forged race car wheels for the Formula One circuit is a testament to our quality. We can supply:
Good Forgeability, Medium Strength
Higher Strength than AZ31B
Higher Strength than AZ61B and heat treatable
Highest guaranteed minimum strength and higher ductility than AZ80

Benefits of Forging Grade Billets

Guaranteed quality
We verify quality by microstructure testing
Full traceability
We maintain full traceability and certify for chemistry
Pre-ex Capability
We can pre-extrude forging billets to improve forgeability
Ultrasonic testing
We use UT certified personnel to test per customer’s specification


specialty magnesium alloys
Magnesium is a key ingredient in many pharmaceutical and chemical/metallurgical applications. Mag Specialties produces a variety of alloys and forms for these industries:
A magnesium-calcium alloy used in the lead industry for de-bismuthizing
A calcium-magnesium alloy used for the lead battery alloying
Magnesium granules and turningS
For the pharmaceutical and agrochemical industries

Benefits of our Specialty Metals

Consistent chemistry and sizing of our turnings and granules enable reliable and high yield Grignard reactions.
Mag-Cal and Cal-Al reduce plant fugitive emissions, improve workplace environment and can be added at lower temperature.
Mag-Cal results in consistently higher recovery of both magnesium and calcium in the lead bath; minimizing reagent additions and enabling more accurate predictions of final bismuth levels.
Cal-Al’s uniform chemistry and high-quality leads to more consistent battery grids and improved battery performance.
