Current Neutronium properties and usage are quite deceptive, given the amount of effort and energy required.
At the technology advancement stage, you are able to produce Neutronium, there is no Neutronium tool you need
First, as an end-game ultimate material, anything built out of Neutronium deserve ultimate statistics and infinite durability.
The sacrilege and funny disinterest for valuable stuffs that is, to craft a Neutronium Hoe, could trigger an achievement.
On a more serious note about Neutronium usage:
- Infinite durability tools and tool-heads,
- infinite durability turbine rotors,
- All machines available in MAX tier, with 1 second processing time, that process recipes at their base EU/t (no over-clock penalty)
- No loss wires (I think superconductors should be no-loss already though)
Here is a detail of how much material and energy you need for 144 l (1 ingot/dust) of Neutronium:
By fusion:
- 144l Molten Neutronium is made of 2,304 l of Molten Naquadria (NqX) and 2,304 l of Molten Americium
- Fusion process consume 117,964,800 EU × 144 l = 16,986,931,200 EU / Ingot (+ Batch start-up cost of 600,000,000 EU)
- 2,304 l of Americium made by fusion 4,718,592 EU × 2,304 l = 10,871,635,968 EU
- Made of 2,304 l of Molten Lutetium and 2,304 l of Molten Chrome
- 2,304 l of Molten Lutetium are made of melting 16 Lutetium Ingots for 1,488 EU × 16 = 23,808 EU
- 16 Lutetium Ingots are made by vacuum freezing 16 Hot Lutetium Ingots for 62,640 EU × 16 = 1,002,240 EU
- 16 Hot Lutetium Ingots are made of Electric Blast Furnace smelting 16 Lutetium Dusts for 924,000 EU * 16 = 14,784,000 EU
- 16 Lutetium Ingots are made of Thermal - Centrifuge processing 2 × 16 = 32 Depleted Thorium Fuel Rods for 16 × ??? EU = ??? EU
- Melting 2,304 l of Chrome requires 16 × 1,584 = 2,5344 EU
- 2,304 l of Molten Naquadria requires melting 16 Naquadria Ingots for 1,848 EU × 16 = 29,568 EU
- 16 Naquadria Ingots requires vaccum freezing 16 Hot Naquadria Ingots for 35,280 EU × 16 = 564,480 EU
- 16 Hot Naquadria Ingots requires Electric Blast Furnace smelting 16 Naquadria Dusts for 720,000 EU × 16 = 11,520,000 EU
- 16 Naquadria Dusts requires centrifugating 90 × 16 = 1440 Naquadah Dusts for 1,024,000 EU × 1440 = 1,474,560,000 EU
or
- centrifugating 20 Enriched Naquadah Dusts for 4,096,000 EU × 20 = 81,920,000 EU
- obtained from centrifugating 8 × 90 = 720 Naquadah Dusts for 1,024,000 EU × 720 = 737,280,000 EU
In the best possible scenario excluding start-up costs, mining and processing ores;
Production of 1 Neutronium Ingot cost:
1,000,000,000 EU average, in Naquadria Dust processing
+ 11,520,000 EU smelting Hot Naquadria
+ 564,480 EU freezing Naquadria
+ 29,568 EU melting Naquadria
+ 10,871,635,968 EU fusioning Americium
+ ??? EU processing Depleted Thorium cells
+ 14,784,000 EU smelting Lutetium
+ 23,808 EU melting Lutetium
+ 1,002,240 EU freezing Lutetium
+ 2,5344 EU melting Chrome
+ 16,986,931,200 EU fusioning Neutronium

Producing 1 Neutronium Ingot by replication:
- Replicator 100,000 l of UU-Matter with 1,638,400,000 EU
- 100,000 l of UU-Matter mass fabricated for 32,000 EU × 100,000 = 3,200,000,000 EU
Total cost of replication:
1,638,400,000 EU
+ 3,200,000,000 EU
= 4,838,400,000 EU
