Good presentation. Im 50 yrs old and I learned something new.

now that was weird. I am almost 50 too and for a moment i thought "wow an old man" but then i realized i am in the same age.....

Anyone trying to identify an aluminum vs stainless beer keg for making a moonshine still should watch this. Incredibly valuable knowledge. Thank you!

Nice tips for quick identification. Thanks for that!

These tips are So valuable when fabricating.

A very nice intro to materials for anyone doing metal work, machining or welding. Would also like to see some basic visual and destructive tests that can be used on samples of these materials to help in choosing the best welding procedures, fillers and pre/post treatments for welding them. Thank you.

thanks for teaching

Titanium do sparks even if it is non-ferrous material because in contact with oxygen it will burn before melting.

Figured that's why sparks were bright

Unfortunately, There are numerous variables in detecting the type of aluminum alloy. Say for instance, we can eliminate a few of the aluminums by bending..... 3003 and 1100 series will bend and shape nicely.... 6061 -t6 has great tensile strength but will not form well in to a tight radius without cracking. You will need higher dollar instrumentation to realize a specific aluminum and temper. Good luck Mister Tig

Thank you!

Thanks for this information

I love the video but it is a shame that variety of samples wasnt broades, I'd like to see magnesium too, I know for certain that it is unnoticeably lighter than aluminum and probably produces sparks, since it is quite known for sparks, besides looks a lot like aluminum aside some differences in chemical activities... What else... Inconel maybe? Besides cast iron has some variety to it.

An excellent project

wa woo~😲😲😲😲😲 so nice thank you Mr Tig & Bob .

Thanks for the info!!!!

Thanks!

Great thanks

I currently deliver a course that includes identifying metals via a spark test. Very interesting.

Thanks for this good knowledge. How can we differentiate lead and zinc . Waiting for a comment.

Hi 4 year old comment. A simple answer is weight and softness. Lead will be about 1.5 times heavier than zinc and much softer and easily bent unless it’s heavily alloyed with antimony. It also will be much duller and grayer in color where zinc will be a lighter gray with a barely noticeable bluish tint to it

Wow great video .. most important thing I learned , don’t grind aluminum without using special mediums , also I did not know some stainless is magnetic. Definitely saw the bluish white titanium sparks and distinctive mild steel sparks.

Good practical stuff here.

Great Video....Thanks Don M.

I wish there were a couple high carbon examples, all were low carbon or alloys..

Cast iron is high carbon

@chrisplayz253

High carbon will hardly give off any sparks at all because it's so hard at a more orangey colour

@11:28 next test: zinc and nickel and their alloys including copper + nickel + zinc

Amazing vídeo. Thanks a lot

The following is more a reference than anything else. How do you tell the difference between aluminum series? As an example AW 1050 to AW6060 as a current example, is there a basic way of differentiating? On a side note the unobtainable alloy was obtained today at 13:30 hours

1xxx series aluminum is a minimum of 99% aluminum and the next 3 numbers help determine the exact percentage and impurities in it. 6xxx has magnesium and silicon in it. What makes you so interested in it are you planning on being a mechanist or a welder. It is a great skill to know all the deferent types of metal I personal am an aluminum boat welder.

+Ethan Schulz This I am kind of aware of, why I am interested is because I am currently working on some aluminum which I would like to know precisely which series it is, and I know is either AW 1050 or AW 6060 or something close.The 1xxx should be softer and more bendable compared to a 6xxx right? Are there any more ways to determine which series one has, I would like to know as I am welding. Thanks

Very interesting. Superb video. I would suggest trying a file next time. I watch your videos all the time and have learnt a lot.

Thank you for that great info.

Didn't know that about grinding aluminum with a regular grinding wheel. I wonder how many times I have cheated death? (:-D

@AntaresSQ01

they don't just straight up explode but die to the softness and low melting point of aluminium it "gunks up" the grinding wheel and your issues stem from that

Titanium is flammable so that should explain the sparks.

Iron is also flammable, which can be seen by steel wool being lit on fire

Mr Tig, can we get a NDT video?

what would you use to weld the titanium?

@joshp6061

ERTi-5 filler wire rods

Is there anyway I could estimate the type of metal I have without having to grind it or mess with it? Like maybe colouring or texture ? Or even feel.

VZY FLAME if you are talking about non destructive methods, there is a method using XRF (xray fluoresent) scanner. It can tell you the chemical composition of your metal. But those machines are expensive.

Woh amazing

magnesium would be good (wheels)

That cast iron is hard, thus no sparks (grinding wheel just glide on it)

Who can buy Titaninum purhase

👍🏾👍🏾

i think alloy is never produce spark.

These guys Both wanna Talk.......lol

Really need to look up the word magnetize you are using it improperly. You provide no close-ups of anything that you talk about like you supposed to take your word about the differences in grain?!

Hi ,at 0:30 you correctly said material, however later you said metal. Now of course you guys know what you have in front of you, but at 0:43...... you should say MATERIAL, not METAL. We all occasionally fall into the trap of speaking in a generic, but nevertheless misleading manner.Better to say material .The moment you introduce non ferrous materials the EXPLANATION becomes very,very different. You know I am correct ,as you say, for the "benefit of the STUDENTS".
