Alloys: Types and Examples

We know that liquids and gases can form mixtures, but did you know that solids can, too? Even metals! Mixtures of metals are called alloys, and they have tremendous technological application. What is the structure of an alloy? Are there different types? What are their properties and what do we use them for? Let's take a look now!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

And exactly how they are made is another fascinating subject. Steel, besides having so many variations in composition, can be made to vary a lot just by how it is heated and cooled. Tempering, hot quenching, hot-working and cold-working are some examples. A whole career can be made studying just 'steel'.

Some of the most famous alloys: stainless steel, brass, and pewter! Excellent discussion on lattices, Professor Dave. The engineer and materials scientist in me was glowing!

Minor point, electrical wiring tends to be as pure copper as realistic for the application as alloys typically have higher resistance

My HS teacher gave us a trick to figure out brass and bronze. You know one has zinc and one has tin. But which one? Well, bronze has "nz" in its name which stands for "no zinc". Then I go to college and realize there are countless alloys of brass and bronze.

Yep, there are literally thousands of alloy compositions which is part of the reason why metallurgy is such a complex subject. Sadly a dying pure discipline compared to 30+ years ago when I studied it.

If only steel manufacturers would code alloys in such a simple and intuitive manner... A few days ago I spent almost 2 hours browsing the differences between a bunch of tool steel types, found out there are multiple coding systems for pretty much the same thing depending on country and manufacturer and some of those are mindbogglingly convoluted and counterintuitive, I got the distinct feeling they do that on purpose to confuse people who want to find out more about the quality of a certain product.

What I'm wondering is how does the alloying process work? Is it instant? Do you need to stir the molten metals to dissolve it? (like sugar in tea) I'm thinking maybe its like soldering, where the lead is pulled towards the copper wire, maybe as soon as the metal melts, it self distributes. Or, if you don't stir the metal, will it result in a unevenly mixed alloy?

hello.thanks sir.
is general chemistry playlist finished now?

[mawada-juux]

big thank to you Professor Dave this play list save my time to remember the basic, I prepare now to master test wish me luck

[fourk_]

Thank you for still making these videos despite your conspiracy debunking videos getting 100x the views


We really appreciate it

[yigitcan]

Professor I have a quesiton, what's the differences between cast iron and steel rather than %C content?.Both of them ferrous alloys and iron is the main component in them

[hamedhaidari]

loved that, I was looking for this. thanks

[sciencenerd]

procrastinating my real homework (writing a paper about vocabulary interventions) so I could watch this

[anythingbutordinary]

sir what actually do we mean by zeroeth, first, second order reaction in chemical kinetics

[kontiimanalatit]

Can you make a playlist about materials science?

[XanderisMLG]

how the hell are you making it to MY recommended??? my science teacher watched 2 of your videos and now im getting your videos in recommended

I am trying to science my enchanted metals for the science fantasy I am writing. Magic is essentially a consciousness-changing reality but some metals "conduct" this better than others. Aluminum will be the "super-conductor" that would be top tier mage-metal. I was thinking that mercury could be "quicksilver" but gallium looks better. I am thinking that would be some sort of alloy but not sure what would be a good alloy with gallium or mercury that would make "quicksilver". Then I would use "Nordic gold" as a magic metal, but I would rename it to "High Bronze" and if gold was added it would be "True Gold". I am thinking that "True Sliver" would be a Sliver alloy of tin, platinum, and Aluminum. I think that "True Gold" is a possible alloy but don't know about the others. Any resource that I could use that would help me with this?

The Superconductors are Aluminum and Gallium. The normal metals that are enchantable are iron, cobalt, nickel, and copper, they have plausible enchantablity, and the good but not perfect would be the platinum group metals, Rhodium, Palladium, Silver, Iridium, Platinum, and Gold.
Brass and Bronze are enchantable and are good for certain things but zinc and tin do nothing on their own. Brass of course is good for the sound type of enchantments and allows the "Deus Machina" to talk. "Deus Machina" will be the term I will use that would have machines that use magic and magic spells to operate. Magic on its own would be a technology in this world. And gems with Aluminium or with the other mentioned metals would be either mana stones, they are magic batteries, or they will hold spells and convert magic into the desired spell. So the "Deus Machina" will be themed with Brass, Bronze, Gold, and gem elements for them to function. Spell work would be like a programming language when written to scrollwork or gem "grimoire". If you have any possible resources on alloys that work and I can make magical, or gems of certain types of chemistries that would be a big help.

U are better then my science teacher 😂, thanks 😊

[planetearth]

More Dave is always good for our brains.

[mawashiyomiradio]

Very nice. Good clip. thanks for sharing.
