			==== Concrete ====

			The cast concrete alternate recipe is unique in that the base recipe it is replacing doesn't use metal plates at all, but instead raw [[iron ore]]. Thus, in this case, the inherent +50% productivity bonus of the foundry ''does'' matter, since there is no way to integrate a foundry into the production chain while using the normal recipe. This inherent bonus (which applies twice, once when melting the ore and again when casting the concrete) more than makes up for the cast concrete recipe's inherent efficiency of only 50%.

			Additionally, the cast concrete recipe is considered an intermediate product and thus accepts productivity modules, while the normal recipe is considered a finished product and does not, allowing additional productivity bonuses. The ore melting step is also an intermediate product accepting productivity modules.

			Finally, concrete requires non-metal ingredients as well: [[stone brick]] and [[water]]. While the cast concrete recipe has an inherent efficiency of only 50% with respect to iron ore, its inherent efficiency with respect to the other ingredients is exactly 100%. Using the foundry allows these ingredients to benefit from its inherent +50% productivity bonus, as well as any productivity modules used.

			Thus it is always preferable to make concrete in the foundry if possible.

	Initially, it seems like the electric furnace, with just 2 module slots, cannot make up for the 67% inherent efficiency boost from the cast-steel recipe. However, steel production also has an [[Steel_plate_productivity_(research)\|infinite research]] which adds a productivity bonus; while this bonus applies to both casting steel and smelting steel (and ''doesn't'' apply to casting iron plates in order to smelt them into steel), the 50% inherent productivity and more module slots of the foundry give it a higher bonus to start with, meaning that the same ''absolute'' bonus makes for a larger ''relative increase'' in the electric furnace. For example, with no productivity modules, researching 5 levels of the technology will take the foundry from 50% productivity to ~~100~~% productivity, boosting its output by a third. By contrast, the furnace will go from 0% productivity to 50% productivity, boosting its output by a half. With the right combination of high-quality [[productivity module 3]]s and steel plate productivity research, it is possible to make the electric furnace production chain more efficient.

By contrast, the furnace will go from 100% total productivity to 150% productivity, boosting its output by a half. With the right combination of high-quality [[productivity module 3]]s and steel plate productivity research, it is possible to make the electric furnace production chain more efficient.

	For example, a foundry with 4 legendary productivity module 3s (+25% productivity each) casting iron plates feeding an electric furnace with 2 legendary productivity module 3s and a +50% steel plate productivity has exactly the same overall efficiency as a foundry with 4 legendary productivity module 3s and the same +50% steel plate productivity casting steel plates directly, with both producing exactly 1 steel plate per 10 units of molten iron. Any additional research past that point will make the electric furnace production chain strictly better. If using mere rare productivity module 3s (+16% productivity each) instead, the changeover happens somewhere between +150% and +160% research.

Any additional research past that point will make the electric furnace production chain strictly better. If using mere rare productivity module 3s (+16% productivity each) instead, the changeover happens somewhere between +150% and +160% research.

	Additionally, with enough levels of steel plate productivity research, it is possible to reach the hard cap of 300% productivity. Thus the absolute maximum efficiency possible for casting steel is 4/3 steel plates per 10 units of molten iron, while the electric furnace production chain can reach 2 steel plates per 10 units of molten iron.

	Unlike all the other items with alternate production chains here, [[pipe\|pipes]] and [[pipe to ground\|pipes to ground]] are not intermediate products.

	==== Copper cables ====		==== Copper cables ====

	Much like iron gears, copper cables have a 200% efficient casting recipe and no researchable productivity bonus, thus it is not possible to produce them more efficiently using an assembler. However, copper cables can also be produced in the [[electromagnetic plant]], which has ''5'' module slots and an inherent +50% productivity boost of its own. So long as the electromagnetic plant's ~~total~~ productivity is greater than 100%, this production chain is more efficient than casting directly. 5 productivity 3s of common quality (+10% productivity each) will give a ~~total~~ productivity of exactly 100%; any better quality modules, or productivity 2s of epic quality or better, will make them more efficient.

	Note that making low density structures is subject to its own [[Low_density_structure_productivity_(research)\|productivity research]], and both that, and the use of productivity modules of any kind, will make the use of the alternate production chain more attractive: the efficiency gain for iron and copper will increase, while the efficiency loss in plastic, while not entirely negated, will shrink. For example, with no efficiency boosts, the alternative production chain is 33% more efficient in iron, 25% more efficient in copper, and 33% less efficient in plastic, but with +100% productivity from research, the alternative production chain is 60% more efficient in iron, 50% more efficient in copper, and only 20% less efficient in plastic.
