Brevven!

its Great to see another Great Mod! It's Extreamly fun to see all of these new metals that you add to the game. They really help expand the early and mid parts of the game.

Out of Curiousity, What are your current plans for future mods and current mods updates?

I've mentioned it before but I'd love to see even more raw metals added to the game.

Gold and Silver,

Used for red/blue circuits, solar power, heat cable for nucular power, rocket controlers and satelites. Maybe a ingot/plate form for Multiplayer trade use?

Phosphorous,

Used in incendiary artilery (Not a vanilla item) and weapons and pretty much anything that uses fire. It's also used in LED's (althogh Gallium is the main element)
This one is a bit of a streach but i'll through some Ideas out there and see if it inspires you in any way.

Glad you're continuing to enjoy :)

I have a "backburner" list of possibilities. Previously, Tungsten was near the bottom of the list, but your ideas really helped with that one.
Other things on the list right now (very rough order) include Zirconium (for ceramics), Carbon (eg. Graphite/Diamond), Aluminum, Platinum, Palladium, Silver, Gold, Zinc, Tin, Magnesium, Boron, and Mercury.

When it comes to Platinum/Palladium/Silver/Gold they have a lot of overlap in their broad categories of use, so I think if I did one, it would be a long time until I could make the next distinct, so it would probably be only one of those, and I'm leaning toward Platinum. Any thoughts are appreciated.

I'll add Phosphorous to the list and look into it more! (and might investigate Gallium....)

The big challenge is always making it fit decently into Vanilla Factorio, which is the primary goal of each of these mods. K2 and Space Exploration are basically requirements at this point as well, but Vanilla is the most important. There are a lot of interesting metals whose primary use is in alloys, and alloys don't play too well in vanilla factorio due to the 1-ingredient limitation on furnaces.

I'm Glad you find Vanilla important, I'm a Vanilla+ player and your mods fit right it.

as for your Platinum, Palladium, Silver, Gold issue. My only input is you should pick two and use one of them in red Circuits and and the other in Blue Cicuits. Yes there is over lap, but they can be relegated to their specific teir.

Additional thoughts:

Tungstun Carbide should require Coal (Carbon) in it's recipe. Even when cooked in the electric furnace. (Maybe 1 Tung plate + 4 Coal = 2 tung carb?)
Steel should be the same I feel. So maybe a "Realistic Steel" Mod where 1 Iron + 1 Coal = 1 steel? (Additional coal needed for burning)

Stainless Steel / Galvanized Steel (These would take up the same space)

Galvanized Steel: This could be a use for Zinc, replace all the Late game Steel with Galvanized steel (Steel Coated with Zinc for anti-rusting) This process is normally done by disolving Zinc in a liquid then using chemistry and a electrical current to plate the Steel. This can also be done with Nickle in stead of zinc.

Stainless Steel: an Alloy of Steel and Chromium (with other aditives.) an alternitive idea to Galvanized.

Alluminum: Yes, it fills a lot of the same design space as Titanium. But Honestly. Maybe thats ok. The reason we love these types of mods is because we like how it expands the early and mid game. Having Low desity structure require Titanium, Aluminum and Plastic could be fine. But Maybe I'm wrong.
You could use aluminum in power armor stuff, and Titanium in buildings. You could also seperate them by what color of the Science tree they fall on.

Making a New Teir of Gear:

Iron Gears Used for Yellow belts and Assembling machines (Iron Age)
Steel Gears Used for Red belts and Assembling machine 2 (The Steel Age)
Titanium Gears Used for Blue belts and Assembling Machine 3 (Super Alloy Age)

Creating or supporting mods that add additional Teirs of Drills and Belts would be fun too.
(Advanced Drills by Neomore is the one I personally use, I'm yet to find a good "Belts" mod I like)

Good stuff :) Will take all of these suggestions into consideration.

Tungsten Carbide should require Coal (Carbon) in it's recipe. Even when cooked in the electric furnace. (Maybe 1 Tung plate + 4 Coal = 2 tung carb?)
Steel should be the same I feel. So maybe a "Realistic Steel" Mod where 1 Iron + 1 Coal = 1 steel? (Additional coal needed for burning)

For the current mod, the 1-ingredient limitation of furnaces means we can't do this. So I've made tungsten carbide only craftable in stone or steel furnaces, so that some form of carbon is used. If Krastorio 2 is enabled, Tungsten Carbide requires Coke.

What I might do in the future is make a mod that gives Vanilla furnaces the "Krastorio 2" treatment, so they act like assemblers and can take more than 1 ingredient. That would open up various alloys and compounds. Not sure if/when I'll do that.

Titanium gears is a nice idea for an optional intermediate for that mod. I'll think on this and other possibilities.

Hey brevven!

Thanks for another addition! I really appreciate how considerate and focused you've been towards compatibility. I play a heavily modded SE based playthrough..I can't imagine playing without lead at the very least :)

Regarding the above conversation.. I'd love to see gold for advanced circuits and heatshielding. I understand obviosuly that adding gold, silver and many other similar stuffz can get unnecessarily complicated and difficult to differentiate..especially difficult as well (I would assume) to have them all be compatible but not interdependent.

I would suggest keeping copper for the green circuits and adding gold for advanced and beyond. You could also (as another mod has done I believe, I adore the idea) have the option of using gold for green circuits with increased output or efficiency.

Only suggestions, you seem to know what you're about- Keep it coming!

Thanks for the supportive words, and the suggestions!

I'll definitely keep all this in mind. It looks like a conductive metal is a popular request :)

I have a possible suggestion that goes a little against the theme of your mods

One bigger "precious metals" mod that adds platinum, gold, and silver?

A little off the one mod one material part, but you could have a sister Jewels and Gems mod if that was something you'd want.
