Copper, Brass & Bronze alloys explained

[@darthvader5300]

Typo-mistake correction: It is not 50% copper and 50% copper. It is 50% copper and 50% nickel. This is what they taught us at mechanical engineering school in the 1950s concerning copper alloys, especially the bronzes. 1. silicon bronze: 1% silicon and 99% copper. 2. phosphor bronze: 1% phosphor and 99% copper. 3. aluminum bronze: 1% aluminum and 99% copper. 4. monel: 50% copper and 50% nickel. 5. tin bronze: 10% tin and 90%copper. 6. molybdenum bronze: 40% molybdenum and 60% copper. 7. tungsten bronze: 30% tungsten and 70% copper. 8. manganese bronze: 50% manganese and 50% copper. Additions: 2% vanadium, 3% chromium, 3% misch metal alloy, 1% iron, 1% magnesium. The advent of mechanical alloying wherein you melt different alloys separately and mix them together in a single crucible with an induction stirrer-melter.

4. Monel - you said 50% copper plus 50% copper. Isn't that just 100% copper?

[@darthvader5300]

@@SoulDelSol That is a typo mistake, I mean 50% copper and 50% nickel. Monel naturally came from ordinary monel ores already mixed with nickel and some small amounts of iron, manganese, and others.

@@darthvader5300 thank you for the great information!

[@desertm44]

1% AL & 99% CU? Which Aluminum Bronze alloy are your referring to? I make my own Aluminum Bronze alloys and I never heard of that one.

[@darthvader5300]

@@desertm44 That alloy was developed way back in the years 1960 to 1966 as an architectural exterior material, when I was a young engineer in the early 2000s I saw a building outer exterior paneling made out of that material and I made inquiries and they told me it is 1% aluminum and 99% copper. That building has been standing since the early 1950s and exposed to coastal tropical conditions in Asia for the coast is just several blocks away.

whoa, found me another rabbit hole! thanks, more than I thought to ask! eventually I will find my way back to the previous rabbit hole, which is guns and ammo, which led to wondering about ammo cases, which led me to this. love me some rabbit holes

Wonderful comprehensive presentation

[@benjigray8690]

I came straight here, when I wanted to find out what sorta metal we were cutting up, it looks like what my boss and I both call "gun metal". I am employed in the recycling business, and I've bin interested in metals for a lotta years , some time ago I watched, and then re watched your video about all the different types of stainless steel. Our firm sells the various scrap metals that we process, sorting them accurately is very important. I have found your videos very informative and helpful, Thank you.

[@reprocessors]

Where u from bro?? WhatsApp me at [phone] I m too from scrap metal recycling industry

[@frankcoit7102]

Exactly the info needed thanks guys.

[@pukhraj1988]

Wonderfully explained; very useful

[@stephensu4371]

Pukhraj Sahu yes i agree with you，i can see all the spec. for each type of copper alloy

[@alvaroakatico9188]

We needed a voice tho

[@pauls5745]

very nicely shown to give a rundown of copper alloys tho the common alloy number systems have changed, i.e. C110, C360, C932 and C954

[@paulmarais4988]

For some reason this particular video has no sound for me?

[@Tag-Traeumer]

It says here that copper-nickel has a very high strength (4:53) and beryllium copper has a high strength (2:46). But it's true the other way around: Beryllium copper has the highest hardness and strength of all copper alloys.

[@disarmyouwitha]

extremely helpful, thank you!

[@archangel20031]

Where is the sound?

[@Stoney47]

Why do some bronze have a magnetic pull to them. They look like bronze.

[@sherrys.2259]

Oh God, thank you for the explanation!

How about brass and copper when exposed to heat, will they expand, sir?

[@oksomkar3107]

anyone tell which bronze verity gives ringing sound when hard metal hits?

[@Nittyb123]

Thank you. Just what I was looking for in regards to the C101 copper.

[@timrauscher3965]

Good video with good content. I enjoyed the education. The only thing I can suggest is that it be slowed down a little as I don't read fast enough.

[@HsmwireIntl]

stop the video

[@alvaroakatico9188]

HSM WIRE INTERNATIONAL THE LITZ PEOPLE ok, so we figured it out, just pause the video, great! I can’t believe I didn’t think of doing that. What about a voice? That would help tremendously and it should be a sexy female voice with an accent.

[@gustavoargumanis1863]

Of all the alloys, which ones was the bronze used for warfare in the bronze age? And some people say that brass can be even better than bronze. How is that?

[@georgebelev1900]

So basically everything comes from copper

[@Sierra-tc6yq]

So how can i turn t hat s hit info rolas tuyas the qwestion

[@ajmetalcasting791]

Which phosphorus use black or red ?

[@copperlemon1]

I don't think elemental phosphorous is used in the process. More likely that more readily available and less expensive phosphate compounds are used. Heated in a furnace the phosphorous will be liberated from the bearing material and dissolve into the copper.

[@Sierra-tc6yq]

Can i hope mix with brass

Which alloy of copper has the deepest red color.

[@topgearIQ]

Mg-Cu or Cu-Mg correct coper alloy formala.

[@stevehowe9677]

That would make a Great Wall chart - are any available?

[@Keletho]

Can someone explain why it gives them these properties and what is responsible for these properties

[@gratefuldude941]

Probably.

[@skeeterburke]

i'm not a metallurgist (just have a masters degree in physics, aka 'enough rope to hang myself'), but a lot of the properties of an alloy depend on the crystal structure - such as face centered cubic (fcc), body centered cubic (bcc), and so forth. you can make an educated guess based on the periodic table, the properties of the elements present, and their proportions, but a lot of it comes from handed down experience / observation, or having a phd in metallurgy.

[@Lord_RavnFar_Tannerwise]

all i wanna know is if i mold an iron skillet and smelt down and pour a casting of that skillet in aluminum bronze is it safe to use as intended for food or will it be toxic and unusable!?

[@xGrOsFiRex]

James Smallwood would be probs okay can’t see why u would want to make it from ali bronze tho they normally use that for things like boat propellers or big industrial valves cuz of its corrosion resistance why not just use pure copper to be sure aha

[@bernarddaveau8725]

Présentation générale intéressante. Quelques précisions sur les applications des bronzes au manganèse et au béryllium auraient été les bienvenues

[@bill4639]

Tungsten copper and silver copper are missing. This is a decent video, but I am sure there are even more alloys.

[@MichSignMan]

This vid really helped confuse me!!!, I mean fill my head with more un-needed knowledge :)

[@808zhu]

Very nice. Thanks!

[@sosalish441]

how would one separate the 5% zinc from the copper of an older penny?

[@scottmalchow3428]

Sell it to a coin collector. If you melt and centrifuge while still melted you can separate them, mostly. To recap; Face value is lowest, followed by scrap price and highest by collector's price. Unless you deal in large volume you wont get more than close to collector's price. (very rare and auction)
