1.Product introduction
The high potential magnesium alloy sacrificial anode our company produce (For short:high potential magnesium anode) according to ASTM97-98.It produce with high purity magnesium material and specific technology.Magnesium alloy sacrificial anode have good electrochemical performance.During cathodic protection, magnesium alloy sacrificial anode consume equably,so it have longer service life.During actual use,actual measurement work potential between -1.8v to -1.85v,protective results are obvious.When resistivity are more 8000 Ω.cm in soil,it should use high potential magnesium alloy sacrificial anode.
