Bronze Tank is the entry-level fluid storage block from IndustrialCraft 2, holding 32,000 mB (32 buckets) of any fluid such as water, lava, or biomass. Players craft one Bronze Tank from four Bronze placed in the corners and four Universal Fluid Cells on the edges of a crafting grid, with the center slot left empty, yielding one tank per recipe. Bronze itself is an alloy of three copper dust and one tin dust, so Bronze Tank production chains back through the macerator and furnace. Bronze Tank accepts fluids from adjacent pipes, pumps, or machines equipped with fluid ejector upgrades, and releases fluid through pipes or fluid-pulling upgrades on the same principle.

Bronze Tank works as the standard buffer for early IndustrialCraft 2 fluid systems such as fermented biomass lines, lava generators, and coolant loops. Players break a Bronze Tank with a wrench — the tank's listed tool — and drain the stored fluid first, so 32 buckets of lava survive relocation without losses. Bronze Tank is outclassed by the Steel Tank at 128,000 mB and the Iridium Tank at 1,024,000 mB, but the 32,000 mB capacity covers most early and mid-game fluid needs at a fraction of the material cost. Builders typically place a Bronze Tank next to a Geothermal Generator or Fermenter and forget about refills for long stretches.
