1. Introduction I use magnesium sacrificial anode with a high-quality high-purity magnesium production, product line ASTM97-98 standards, using special extrusion process, with magnesium sacrificial anode (abbreviation: magnesium ribbon anode) with excellent electrochemical properties , magnesium ribbon anode flat shape, the length can be adjusted easily bent. This product is used for high resistivity environment, protect the casing pipe, pipeline cathodic protection temporarily, tank and pipe network protection, anti-strong grounding electrical interference with the chemical composition of the gate 2. Magnesium: Grades Al Zn Mn Fe Ni Cu Si Mg Mg-Mn <0.010 - 0.5-1.30 <0.03 <0.001 <0.02 - the balance of pure magnesium <0.010 <0.010 <0.030 <0.002 <0.001 <0.001 <0.010> 99.95 3. magnesium anode with a standard serial magnesium ribbon core specification ( mm).
