            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

            Specialty Metals

            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.
