Aluminum Location in The Planet Crafter (Map)

852 Aluminum pins in all, on 4 of the 5 planets. Aqualis has none. Each link opens that planet's map with only this layer switched on.

The game files give coordinates but no biome or area names for ore, so I cut each planet's map picture into nine equal parts (north-west to south-east, north at the top) and counted the pins in each. The parts are my grid, not names from the game. The last column is the middle of the pins in a planet's busiest part, in the world units the map popups show.

The picture is lopsided: Prime's busiest part (centre) holds 160 of its 265 pins, and Selenea's busiest part (west) holds 132 of 262.

Every Aluminum pin in the files reads "Mining speed x1.0", the same as every other ore pin, so no pin is slower or faster to mine than another. Go to a pin and mine it. 19 of the 852 pins are marked as spawn points instead: 19 on Humble read "spawns here with 50 % chance". I read that as a pin which may be empty in a given save, so count on the others first.

The ore extractor is the other way in: the game's text for the T2 Ore Extractor reads "Extracts rarer ores from the ground", and the T1 reads "Extracts ores from the ground depending on where it's placed". The files do not list which ore each tier gives; the ore extractor guide has what they do state.

The map also has a separate Veins layer with 2 "Aluminum vein" pins (Prime 1, Toxicity 1): Aluminum vein layer. The files do not say how a vein differs from an ore pin, so I keep the two apart.

42 recipes in the files list Aluminum as an ingredient: 16 items and 26 buildings. The first ones are below; the rest are folded. Amounts are per craft as the files store them. Add any of them to the crafting calculator to see how much ore a build takes.
