The Iron Material is an object that appears in the Sonic the Hedgehog series. It is a type of Material which is used for building and/or upgrading vessels.

Description

Iron Material (Sonic Rush Adventure sprite)

In Sonic Rush Adventure, Iron Materials appear as lumpy chunks of grey metallic rocks (possibly iron, hence the name). In Sonic Lost World, they are lumps in the form of several small black and gray pebbles. Despite the substance's apparent consistency, it is very versatile in building a number of devices.

In gameplay, the iron Materials are used in conjunction with other Materials to build and/or upgrade various machines such as vessels or RC Vehicles.
