Product Description Product DescriptionMagnesium is electrochemically the most active metal employed in common structural alloys of iron and aluminum. Mg is widely used as a sacrificial anode to provide cathodic protection of underground and undersea metallic structures, ships, submarines, bridges, decks, aircraft and ground transportation systems. Following the same principle of utilizing Mg characteristics in engineering advantages in a decade-long successful R&D effort, Mg powder is now employed in organic coatings (termed as Mg-rich primers) as a sacrificial anode pigment to protect aerospace grade aluminum alloys against corrosion. Magnesium alloy sacrificial anodes are used in oil pipeline, natural gas pipeline, underground oil tank, oil platform, water heater, etc., which use the negative potential of magnesium, which is lower than that of steel. Magnesium alloy sacrificial anode features: good protection performance, easy installation, automatic operation after installation, no maintenance, no external current, low engineering cost, easy replacement, etc. Magnesium alloy anode is an ideal cathodic protection method.According to the application requirements, produce high strength, heat resistant rare earth-Magnesium alloy extruded bars, tubes, wire rods, Welding wire and profiles set by national standard, ASTM, EN standard and autonomous development.
