Purity 95% AZ31B Magnesium Anodes Cathodic Protection JIS GB DIN
Factory Supply Magnesium-based Sacrificial Anode AZ31B for Cathodic Protection
Product Description
The magnesium anode has high driving voltage, low current efficiency, and high cost. Depending on the shape and electrode potential (open circuit potential), magnesium anodes can be used in soil or freshwater environments with a resistivity of 15 ohm·m to 150 ohm·m. Generally, it should not be used in environments where the soil resistivity is less than 10 ohm·m. The potential of the high-potential magnesium anode is -1.75V CSE and the driving voltage is 0.85V; the potential of the low-potential magnesium anode is -1.55V CSE and the driving voltage is 0.7V. The use temperature can reach 100°C. When the remaining amount of the sacrificial anode is 15% of the initial weight, the anode is considered to be invalid. Therefore, the anode utilization rate is generally 85%.
The pre-packaged magnesium alloy sacrificial anode body is mainly composed of a magnesium alloy sacrificial anode, a special heat shrinkable sleeve, and a cable. The anode body adopts a packing material with the required composition installed around the magnesium anode body. The pre-packaged magnesium alloy sacrificial anode was developed to simplify the rapid on-site construction procedure. The original operation on the construction site is completed in the factory, which effectively guarantees the construction and installation quality of the magnesium anode bed.
The distance between the sacrificial anode (magnesium anode) groups on the pipeline is 1 to 2 groups/km for long-distance pipelines, and 200 to 300 groups are appropriate for urban pipelines and internal pipeline networks.

Aplication
1. Transportation
Seat frame, armrest, small table panel, pedal, in-built profiles, driving frame, sleeper frame work, dashboard frame work etc.
2. Electronics
Magnesium alloys have excellent thin wall casting performance. They wall thickness of magnesium alloy die castings can reach 0.6-1.0mm, and the die castings can remain certain strength, stiffness and impact resistance. These performances are very consistent with development demand of lightweight, thin short and small for laptop. Mobile phone, digital camera, that makes the application of magnesium alloy grow sustainably.
