Magnesium Battery Sheet and Strip
Magnesium Battery Sheet and Strip

Minimum Order: 0
Quality/Safety Certification: 0.00


a range of magnesium alloys to meet all seawater
battery applications. These include the traditional commercial materials AZ31

AZ31 and AZ61 are high performance alloys which are more

electrochemically reactive and generate much higher cell voltages. This results

in rapid activation and short voltage transience on switching between loads,

making them more suitable for the high demands required for military

applications. The chemical and metallurgical conditions of all these alloys are

carefully controlled to provide optimum properties.

 

CONDITION

AZ31 and AZ61 sheet is annealed and rolled flattened.

AZ31 and AZ61 coiled strip is available as-fabricated or annealed at the user’s

option.

 

PACKING

AZ31 and AZ61 coils are packed horizontally (eye to the sky) in sealed steel

drums with silica gel dessicant bags. Drums are palletized for ease in handling.

 

PRODUCT AVAILABILITY

AZ31 and AZ61 are available as flat sheet or coiled strip. Special shapes may

be blanked in sheet form in accordance with customers’requirements.
