1199 aluminium alloy
1199 aluminium alloy is an aluminium-based alloy in the "commercially pure" wrought family (1000 or 1xxx series). With a minimum of 99.99% aluminum, it is the purest and least alloyed of the commercial aluminium alloys. It is soft and unsuitable for machining. At the same time, it possesses excellent corrosion resistance, electrical conductivity, and thermal conductivity. Commercially pure aluminium alloys are used in applications such as conductors, capacitors, heat exchangers, packaging foil and chemical equipment.[1]

gollark: You could easily store the directory entry bits as an SQLite table.
gollark: This is an excellent use case for SQLite, which would allow quick lookups in the metadata bit and not require coming up with a fiddly custom binary format.
gollark: As you can see from the file format docs (https://wiki.openzim.org/wiki/ZIM_file_format), it's basically big compressed blobs plus directory entry metadata and stuff.
gollark: It's designed for offline viewing of wiki/web content.
gollark: Not as compressed as it theoretically *could* be if they didn't have random access goals.
