	Galvanic Anodes:
	Magnesium Anode
	Magnesium anodes are used to protect most buried metallic structures found in a range of highly receptive soil, magnesium has a greater driving potential than any other galvanic material. These anodes can produce high working driving potential of -1.77 to 1.82 volts (respect Cu/CuSo4); their current efficiency is over 51%. Our anodes are furnished in 3, 5, 9, 17, 32, and 48 pound sizes. Backfill materials for anodes consist of 75% gypsum, 20% bentonite and 5% sodium sulfate. Anodes are available bared and packaged with or without leads as per customer's request. With ELEMENTS INDUSTRIAL's line of high potential anodes, our customers will have the most powerful protection available today. Magnesium Alloy bears the characteristics of small gravity, high intensity, good shock strength, easy cutting and corrosion resistance; it is mainly used in aerospace, aviation, automobile, tractor, motorcycle, nuclear industry, light industry, chemical industry, metallurgical industry, electronics industry, etc.


	Extruded Magnesium Anode
	Extruded magnesium anodes are normally used in water heaters, storage tanks, and in-ground installations. We supply full line of extruded anodes which include both ribbon and rod forms. A solid steel core runs horizontally through all our rods and ribbon anodes for better efficient electrical discharge.
	Aluminum Anode
	We supply a full line of aluminum anodes to protect steel structures in marine environment. This includes vessels, ballast tanks, crude oil tanks, submerged ducts and pipelines in the earth's soil. We have different alloy series to meet customer's specifications.
	Extruded Aluminum Anodes
	Zinc Anode
	Zinc anodes are typically used for protecting of steel construction from corrosion in seawater or saline mud which includes heat exchangers, ballast tanks and submarine pipelines. ELEMENTS INDUSTRIAL'S cast zinc anodes are produced in a variety of weights and are designed for use in low resistivity soil environments. Zinc anodes have a driving voltage which is lower than magnesium; therefore, they are most effective on well-coated steel structures that demand less current output Zinc anodes are widely adopted for protecting of steel construction from corrosion in seawater and saline mud. The alloy chemical composition of the anode are covered by US MIL-A-18001H and the ASTM-B418 type I standard.

	Extruded Zinc Anodes
	The extruded ribbon anode is commonly used in both buried applications of fresh or salt water environments. Cast and extruded zinc anodes should not be used in environments that consist of extremely alkaline (above 9.2 pH), acidic (below 5 pH), or high temperature (above 1400F) electrolytes.
