Our anodes are manufactured to strict quality standards as per ISO
9001 Quality Management System, and ASTM-G97 . In addition,
eachalloy is guaranteed to be manufactured to the latest US
Military Alloy Specification and is chemically tested regularly in
our in-house labs to ensure consistency. Poorly manufactured anodes
may contain high levels of impurities such as iron, which will
leave your investment unprotected.
Magnesium anodes is available with all shapes and sizes. The
magnesium in a packaged anode weighs from 1 pound to 50 pounds. The
most commonly used anode is a 17 pounds anode. With 28 pounds of
powdered backfill packed around the magnesium, a packaged 17 pound
anode weighs about 45 pounds. It comes with 10 feet or 15 feet of
#12, insulated solid copper wire.
The backfill consists of 75% powdered gypsum, 20% powdered
bentonite clay and 5% sodium sulfate. This mixture is a low cost,
nonhazardous, electrically conductive earth backfill.
A cotton bag holds the backfill around the inner metal bar. It
decomposes over time in the ground. The anode is shipped in an
outer disposable, plastic or paper bag to protect it from rain or
snow. It is recommended that 5 gallons of water be poured on the
anode after it is placed in the earth to wet the backfill. This
lowers the resistance between the magnesium and the earth causing
more electric current to flow. This provides more protective
current than would be possible in dry soil.
