Commonly supplied today: EM-112, EM-111 and EM-110 covering 0.5 to 6 in bar, and EM-300 at 25% minimum elongation. Grade datasheets and the full grade list are available on request.
Values are minimums across the grade range on longitudinal extruded bar; individual grades are specified on their datasheet. Dissolution figures are laboratory reference values by static immersion, reported at 93 °C in 3% KCl as standard; a grade can be tested at a condition you specify, and some current datasheets report at a customer-specified 38 °C in 3% KCl. Service temperature classes are the mill’s classification of its catalogue grades, with the working window confirmed for your conditions; the grades named above are specified on their own datasheets and can fall outside these ranges. Compressive strength depends on finished-part geometry and is not specified on raw bar.

Frequently Asked
Questions
What grades of dissolvable magnesium alloy rod do you supply?
More than twenty production grades across three service temperature families. Tensile strength runs from 110 to 450 MPa minimum and elongation from 3 to 40% minimum, depending on grade. Commonly supplied today are EM-112, EM-111 and EM-110 covering 0.5 to 6 inch bar, and EM-300 at 25% minimum elongation. Chemistry can also be adjusted to a target you specify.
How fast do the dissolvable magnesium rods dissolve?
It depends on grade, temperature and fluid. Across the full grade range, reference rates run from 0.4 to 800 mg/cm²·h under the stated laboratory conditions, measured by static immersion. These are laboratory reference values, and the rate should be validated at your own service temperature and fluid chemistry.
Can dissolution rate and mechanical strength be customised?
Yes. The alloy chemistry is adjustable, so dissolution rate and mechanical properties can be tuned to your downhole temperature, pressure and required dwell time. Send us your conditions and we will engineer the chemistry to match.
What are dissolvable magnesium alloy rods used for?
They are machined into dissolvable downhole tools such as frac plugs, frac balls and sleeves. The tool holds pressure during the completion stage and then dissolves in the wellbore fluid, which removes the need for a milling run to clear it.
What are cast sacrificial magnesium anodes used for?
They provide cathodic protection for buried and submerged steel structures, including pipelines, storage tanks and marine structures. The magnesium anode corrodes preferentially so the protected steel does not.
What is the chemical composition of your magnesium anodes?
They are high-potential Mg-Mn alloy. Manganese runs 0.5% to 1.3%. Silicon and aluminium are each held below 0.008%, and iron below 0.03%, because those impurities reduce current efficiency.
How do I read an anode specification code such as 32D5?
The code is weight, shape, then length. 32D5 is a 32 kg D-type anode that is 5 feet long. Shapes are R for round, D for D-shaped and S for square. Round anodes run 2-12 inches in diameter, D-shaped 3-8 inches wide, and square from 2x2 to 6x6 inches. Custom dimensions are available on request.
Why do you export bare anodes instead of pre-packaged ones?
A pre-packaged anode carries roughly 20 kg of backfill per unit across the ocean. Exporting bare anodes to North America removes that weight from the freight bill, and the backfill is sourced locally instead.
Do you publish compressive strength?
Not on raw bar. Compressive performance depends on the geometry of the finished part, so it is confirmed on the machined tool. Tensile strength, yield strength and elongation are specified for every grade.
Do you ship to both the United States and Canada?
Yes. We deliver duty paid (DDP) to both countries and act as importer of record, so you see one price at your dock. Air or ocean freight depending on urgency and volume.
