Cathodic Protection AZ61 Magnesium-base Alloy Sacrificial Anode
Product Description
The use of magnesium sacrificial anodes for cathodic protection is an effective method to prevent metal corrosion. Magnesium alloy sacrificial anodes have the following characteristics: good corrosion resistance, no external DC power supply, automatic operation after installation, no maintenance, and less floor space , The project cost is low, and there is no interference with the external environment. Magnesium sacrificial anodes are widely used in petroleum pipelines, natural gas, gas pipelines and storage tanks; ports, ships, subsea pipelines, drilling platforms; airports, parking lots, bridges, power plants, municipal construction, water treatment plants, petrochemical plants, smelters , Corrosion protection of gas stations, water heaters, heat exchangers, evaporators, boilers and other equipment.
Magnesium alloy sacrificial anodes are used in oil pipelines, natural gas pipelines, underground oil tanks, oil platforms, water heaters, etc., which use the negative potential of magnesium, which is lower than that of steel. Magnesium alloy sacrificial anode features: good protection performance, easy installation, automatic operation after installation, no maintenance, no external current, low engineering cost, easy replacement, etc. Magnesium alloy anode is an ideal cathodic protection method.

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.
3. Aerospace industry
Engine shell, parts. Skin and cabin, frame, holder, wingtip,
aileron, fuel tank, gearbox, airscrew, seat, undercarriage, all
kinds of shell, siding, clapboard etc.
4. Military industry
Panzer tank vehicle, torpedo, guided missile, aircraft /
spacecraft, military electronic equipment, military statellite.
5. Medical industry
Medical device and implant material.
Our Advantages
Corrosion protection
