eh, can't really confirm your tungsten hypothesis, but wolfram would be perfect for this.

I was thinking of making a weapon out of it

>>4752729
Everyone knows tungsten is for railguns.
OP, you silly goose.

>>4752740
No like a sword. You silly goose.

>>4752749
>density of tungsten: 15.8 g/cm^3
have fun figuring out how to carry that mofo

>>4752755
Exercise like a badass. No but, if there is an alloy or element that is conductive, can be put into a sword, I'd like to know.

I understand that this topic seems silly and childish, but just for knowledge's sake, would anyone know?

Hi OP. Material Science grad here. What kind of strength, hardness, and conductivity are we talking here? If you'd like to find out on your own look up a program called CES edupack.

define each of those terms for me. Because strength and hardness seems to be the same for me.

Also, I have to go for now, but within the next 12 hours I'll respond again. So I haven't given up.

>>4752799
I've returned with answers to your question. I'd like for the weapon to be slightly curved, so this calls for it being malleable at higher temperatures, yet stiff at lower temperatures. I'd like the weapon to also be conductive enough were if the object were to touch something the current would travel into the following objects, but at the same time I'd like the weapon to have a look as if it is not electrified. Also, having the weapon last a long time would also benefit. But I am not familiar with how metals reactive physically when current is run through them.

Weeaboo assberger detected. I'm out.

This is now a Katana vs Claymore thread.

>>4752676
try graphene:
conducts electricity the best. glad wrap thick sheet is bulletproof, plastic.

>>4753996

>>4752749
A sword railgun?

Which is more suitable for firing out of a railgun, a tungsten claymore or a tungsten katana?

What about a tungsten katana rail claymore mine?

FRONT
TOWARD ENEMY

>>4754006
>>4753996
What if it's neither and your just making butthurt assumptions?

>>4753998
Plastic conducter?

>>4753996
What if you're just butthurt with assumptions?

>>4753998
Since when is plastic conductive?

tungsten doesnt conduct electricity well, that's why it's used in incandescent bulb filaments. steel is a good conductor, strong (in tension, compression etc.) and is not brittle. so go with steel.

>>4754043
I'm making an assumption based on the evidence that ANYTIME a kid asks a question online about making a sword, it's because he's a weeaboo assberger furry and he wants to be just like his favorite anime character.

>>4754044
Any specific steel in mind?

>>4753996
As a historical fencer (shut up), I feel that the German long sword is a much more appropriate European equivalent of the Japanese sword - Given that the fighting styles used with them were nearly identical, and their sizes and weights are much closer than between the claymore and katana.

See how similarly their use the langschwert is to kendo? First half of the video he's half-swording, which the Japanese didn't particularly do, but if you skip to about 3 minutes in you'll see the similarities.

>>4754044
Tungsten isn't a bad conductor. It's only about 1/3 as conductive as copper, but it's still about 20 times as conductive as nichrome, which is typically used for heating elements.

It's used in incandescent bulb filaments mainly because of its tolerance of high temperatures. There aren't a lot of materials that stand up so well to being white hot.

>>4754056
I once read a long post about why european swordfighters versus (say) samurai would probably win handily, statistically speaking, due to the strength of 1) euro armor and 2) euro swords. He made the point that asian swordfighting was based on a model where killing strikes were in any way realistic, rather than incapacitation or wounding in the european model. As I recall, there was much weeaboo raging at the thought that their beloved might fall against a silly dark age knight but that's fucking life deal with it.

>>4754050
5Cr-Mo-V

the specific alloy can only be determined by knowing how it's going to be used and what loads it will endure, the desired workability, corrosion requirements etc. this means you need to calculate shit and figure out how it's going to be manufactured.

conductivity can be achieved in other ways besides having the base material itself conduct, e.g. a conductive plated edge and a copper mesh through the material.

>>4754068
Yeah, that's certainly true. I would suggest that the Europeans were much better trained fighters all around, but usually that causes a great deal of rage. There's no arguing about the quality of the equipment though, the Japanese simply didn't have access to the same quality metals.

>>4754080
Thank you so much. Say, can this metal be conducted to a point where the heat can break other steel objects? Like let's says go through metal?

>>4754130
Are you trying to make a fucking electrified sword or something?

>>4754159
Well, you guessed it, I'll give ya that. No but before assumptions start flying of being a weaboo or any other terms, I'd first like to say that if I make a sword that is electrified, it'll have it's our design, but it will be inspired from multiple swords, indifferent of its' country's origins.

>>4754171
How the hell do you intend on doing that without killing yourself? You're going to have to carry a backpack with a big fucking battery in it wired to your sword or something. You're probably going to kill yourself. Going to work now, but will keep this open for later.

>>4754178
Well, I plan to have an on/off button. And my only form of power that I can get at the moment would be a car battery, but that won't last me long. Another alternative is solar power, but I don't know how long that will last.

>>4754183
>I want to make a solar-powered electric sword.
I want to throw you through a window.

>>4754196
The panels aren't on the sword idiot. And that was just an idea, I never said I would actually do it, but if I did, I would place a panel on a body part while allowing the energy flow into the sword.

>>4754183
>Another alternative is solar power, but I don't know how long that will last.
5 billion years.

also
>tungsten sword
It will be heavy.
also, tungsten is not flexible like steel, it's brittle. there goes that idea.

Use an induction oven and a normal cheap dagger or shortsword if you want magic fire weapons, a sword would fold under it's own weight.

>eh, can't really confirm your tungsten hypothesis, but wolfram would be perfect for this.
Spoilers: tungsten is wolfram in english.

in before confused swedes.

>>4754207
What good is a brittle sword?

>>4754207
By I don't know how that will last I meant, does it supply me quickly enough with power, even while I use it often?

>>4754068
The samurai would win in actuality due to his main weapon being a bow.

Furthermore, judging the quality of swordsmanship on the quality of armor is silly. Assume both combatants are near-naked if you want to judge the swording ability, otherwise you're just making arbitrary conditions.

>>4754252
Any 100°c+ metal will bleed heat like a headless horse. You'll need a fire with bellows or a ~10kW powersource. No matter how you cut it.

If you're doing a movie where you need a short scene with the magic firesword this is a viable idea. Otherwise it's entirely unfeasible, you'd need a futuristic powersource.

>>4754268
>The samurai would win in actuality due to his main weapon being a bow.

The Euro's had pretty good archers too you know...

>Furthermore, judging the quality of swordsmanship on the quality of armor is silly. Assume both combatants are near-naked if you want to judge the swording ability, otherwise you're just making arbitrary conditions.

Its much more reasonable to judge the quality of their swordsmanship naked and with bows, just like a real sword fight! The Euro's were much better swordsmen anyway, their martial arts were a great deal more refined.

>>4754279
It's supposed to be electrified. Nothing should be on fire.

>>4754303
It's just supposed to be electrified?
You realize it won't shoot sparks or anything. At best you'll get some st.elmos fire or whatever.

A plain old steel sword is conductive enough. Other than that, well bronze, being a copper alloy and pre-iron weapon material should work.

>>4754320
This video is gonna make me look like a complete weaboo, but this is the closet example I could find. Go to 1 minute to 1:05,
watch?v=AtM3PGyiQUc

> Furthermore, judging the quality of swordsmanship on the quality of armor is silly. Assume both combatants are near-naked if you want to judge the swording ability, otherwise you're just making arbitrary conditions.
They weren't arbitrary. They were real warrior classes that really existed.

Any more ideas? Besides what metal to use, anybody got any ideas for a power source?

Use copper wire. Why would you need something to conduct electricity and bear a load?

Copper.

>>4752760
What's copper?

What are copper alloys such as brass and bronze?

What's weapons used for thousands of years?

>>4754635
You're not OP. I am you idiot.

>>4754621
I want something of a mix of a sword and a taser. I would like to be able to conduct enough electricity to be able to cut through metal, yet it does not melt on itself.
