ASTM Magnesium Extruded Rod Anode Anti Corrosion Mg Mn
55% Current Efficiency Extruded Magnesium Anode For Cathodic Protection
Introduction:
Extruded magnesium anodes have a high surface to length ratio in relation to cross-sectional size. This allows these anodes to deliver higher current per weight than standard cast magnesium anodes. By delivering more current, extruded anodes can provide effective protection for structures buried in high-resistivity soils.
Features:
The extruded magnesium alloy anode rod adopts a continuous drawing production process. The surface of the product is smooth, without pores and slag inclusions, the potential is greater than 1.48V, the efficiency is greater than 55%, and the bar yield is over 98%.

Process flow:
1. Ore smelting (crude magnesium)
2. During the refining process of crude magnesium refining (magnesium ingot), the components are tested by the spectrometer in order to meet the national standard. The samples are reserved for two years for quality tracing.
3. Magnesium ingot casting rod (in the casting rod process, use the spectrometer to test the composition again, and record the heat number. For subsequent quality tracking)
4. Extrusion (the composition of the extrusion process remains unchanged)
5. Cut
6. Packaging
7. Shipping
Application:
Extruded magnesium anode rods are used in a variety of applications due to their different functions. These rods are very flexible and play a critical role in diverting corrosive fluids away from the main module. They can be used for low ceilings and compact spaces.
