My question is about the tv picture tube tail on the back of the screen. I know the yoke with copper windings is there,but has anyone ever busted the tail off the picture tube and got the little bit of metal out of it? I have and some of it is non-magnetic...I would like to know what type of metal this is and is it worth breaking open the glass tail to get it out, thanks...junkdude1959
I would say it's not worth busting for the metal. There is a good video on Youtube about "scrapping a TV".
People may laugh at me, but that's ok. I laugh all the way to the bank.
yeah i watched that and theres no info as to what kind of metal it is,but thanks for the reply...keep on scrappin'''
hi, i went on google to try and find out a little about the non-magnetic parts your talking about. what i found is a good direction but no real answer to your question. the parts in the back of the tube make up whats called an inline electron gun. the gun is made of heat deflecting material but thats all they say! i went onto madehow.com and used the search terms what material is a inline electron gun made of, and searched from there. i hope this helps and please share what you find. ill look more into it my self as ive wondered what they are my self thanks for the challange questions like this need to be asked so we all can be a little better at our jobs.
The film on the inside of the CRT tube is a Phosphor coating. See here: Parts of a Cathode Ray Tube
Then look here on wiki: Phosphor and there is a sections that says what is. Not sure if you can scrap it or not (assume you can), but you would have to vacuum A LOT of tubes in order to get enough to make it worth while. It is a very very thin film!
Hope it helps!
thanks,i was just wondering about the non magnetic metal in the tail end of the tube,what type it is and if it was valuable
Im still wondering what to do with the tube when i am done.
Dluback is one place. I think you have to send in pallets and pay for shipping, but I believe they actually pay for the tubes! If you want, look for other "Glass-to-Glass Recyclers" to get of the tubes, or melt them down and separate the lead out if you can. (with proper safety precautions of course)
To answer your question, the metal you are speaking of is stainless, and the little bit that is there is hardly worth the problems of breaking open the CRT tube.
According to the EPA, if a CRT tube is left intact, it is considered a "commodity", BUT the moment it gets broke, it is then "Toxic Waste".
CRT glass is coated with lead and very few "glass companies" are even taking it now. The company mentioned above, " Dlubak" is one of a few that will process this type of glass.
They will charge you to take the tubes from you, plus you also pay for freight.
Unless you are getting into E-Waste recycling in a big way, I would back off from it, as more and more States are passing Legislation concerning E-Waste.
This is a "Good Time" to get into it, BUT, be advised that each state has different laws concerning it and it is a very specialized market, so if you are just doing a few here and there, well, there are a lot of things that you can make a LOT more money on.
Good Luck !!

i work for a e-waste company and we deal with dlubak to take the glass tubes and what i was told that not many take tubes.we ship out a full transport trailer of tubes every day or two.It is not hard to dismantle a t.v but to make money of the tubes alone it is not worth it if u r a small operation or doing it in your back yard plus the safety steps and regulations r strict
I find my TV's and CRT's in the trash, so when I'm done with teardown, they go back in the trash....just with a little less cream filling
I was reading an article in National Geographic once about pollution and they were showing people in China and Africa crushing the tubes and heating the broken glass (in the same pans they eat out of!) to recover the lead.
The article said that this is what happens to many of the CRTs that get donated to non profit thrift stores and it's a big ecological problem.
Many municipalites take TVs and monitors as part of their recycling programs. I'm not really sure what happens to them after that but I suspect they sell them to some enterprise that gets the lead out of them in a safe manner. My city will take them after I've looted the copper out of them. I have to take them to the collection station but at least I can feel like I got rid of them properly.
The metal is made of cesium alloy, the filament is made from tungsten. See http://wiki.answers.com/Q/What_metal..._gun_made_from and http://www.enotes.com/how-products-e...thode-ray-tube for related answers
Welcome to the Forum 21.
Thanks for that second link, I like that site, makes for good reading.

I feel it's all up to you . The bottom line is if you collect a bucket of non ferrous metal regardless of type, in time you will have a filled 5 gal bucket worth some good money as they will pay you for SS or AL at the very least . even if it is cesium alloy you need the yard to except it as such.My yards would look at me and say WHAT !!
So if your there already taken it apart you can put the thing in a 5 gal bucket
