Magnesium sacrificial anode is the core anti-corrosion material for cathodic protection. It provides long-lasting and reliable corrosion protection for buried and submerged metal structures through preferential electrochemical corrosion. Featuring negative potential, high driving voltage and stable current output, it is widely used in high-resistivity soil, fresh water, storage tanks, pipelines, ships and steel structures. We supply cast anodes (ingot type, D type, bracelet type) and pre-packaged anodes with cotton bag and backfill.
- No external power required
- Easy installation, maintenance-free
- Long service life (10–20 years typical)
- Stable current output in high-resistivity soil
- ASTM B843 / GB/T 17731 certified
