Noalox Anti-oxidant joint compound is used for aluminium-aluminium and aluminium-copper connections.
It is ideal for use with LiFePO4 batteries which have copper and aluminium terminal posts.
If the terminals are cleaned thoroughly then coated with Noalox prior to jointing it will protect the metal and prevent reoxidization.
Especially useful with copper interconnects. The grease by itself is non conducting but contains a high proportion of fine metallic zinc powder. When in contact with a joint it promotes good conduction and excludes air.
