H1 Alloy

Alloy H1 anodes are acceptable, in place of very expensive high potential alloys, for most applications where magnesium is required. MAG+(plus)™ anodes are produced to high standards of core wire, anode weight, and packaging. MAG+(plus)™ H1 anodes are formulated from an alloy of the correct chemistry and electrochemical properties that clients have come to expect from magnesium anodes: you get a high-potential, high efficiency anode at a fitting price.

The typical open circuit potential of MAG+(plus)™ H1 using ASTM standard G97, is 1.57-1.60 volts with respect to a saturated Cu/CuS04 reference cell. The inherent potential of MAG+(plus)™ H1 is the reason that these anodes have a current output equivalent to similarly sized high potential anodes. These anodes have high current capacities, typically delivering 500-550 amperes hour per pound in the ASTM Standard G97-89 test.
