Great video. Well clear.

answer to all your P/M questions can be found in the 7th Volume of the ASM Handbook, 0871703874. The entire 1146 page book is devoted to powder metallurgy

Thanks batman.

[marek0086]

very informative!

great vid batman =)

CPM 10v, very tough, holds an edge great

[Ace7388]

Good video, short and sweet.

[terence20001]

Great instruction. Enjoyed.

GOODM VIDEO WELL EXPLAINED

The majority of parts we make are mainly copper. We manufacture metallic brake pads and clutch facings. Most parts are sintered under pressure in bell furnaces, but there are some belt sintered ones. 24 years experience.

Lastly, I neglected to mention one added benefit of making something from powdered metal. Because it is porous, it will naturally retain lubricants, inhibiting corrosion and add valuable lubricating qualities. When the part heats up, the lubricant will tend to bleed out of the part to the surface. As it cools down again, the lubricant is drawn back in. In fact there is a line of self lubricating bronze and copper steel bearings readily available.

[marmaladekamikaze]

Sounds great but what are the disadvantages? lower tensile strength? more brittle?

[Cstrife234]

@marmaladekamikaze I suppose that has a lot to do with the specific application using specific blends (alloy) and the heat treatment that goes along with it.

[nturn65]

datzfast - yes, some magnets are made from powdered metal. Most people have seen powdered metal parts before and never even realized they were made this way.

[nturn65]

And another advantage... the material can be brazed with the use of pressed brazing pellets. This allows bonding of mating components in the sintering process, further adding to the complexity of shapes achievable.

[nturn65]

The alloys get their properties during sintering. Nickel or copper in the mix melt sooner but can't go anywhere easily because the iron is still quite close to solid. Infiltration of copper involves placing a pressed copper wafer on the part. Because the part is naturally porous, the copper melts long before the iron reaches the "critical" temperature and gets sucked into the part through capillary action. Copper infiltration increases density, hardness, tensile strength & improves machinability

[nturn65]

desertblbluesman - been working in the industry for 24 years now, mfg. automotive and non-automotive parts. The material is always an alloy, and it is only called powder metallurgy. Its advantages are: 1. Complex shapes at a lower cost. 2. Tight tolerances can easily be achieved with machining or burnishing. 3. Material can be hardened or tempered. 4 Material can be copper infiltrated to increase hardness, tensile strength and improve machinability.

[datzfast]

is this how neo magnets are made?

[fordieform]

good q!

[desertblbuesman]

could one call this particulate brazing? Are fluxes used? Is the metal formed considered an alloy or a particle mix?

[desertblbuesman]

in what ways Is this method advantageous to smelting and casting alloys? And i am a bit confused as how alloys are made with different solidous and liquidus temps using this method? love this series of videos and thanks to the producers.

[Patrickszasza]

can someone give me a site where can i find surgical tools made by powder metallurgy?need picture's and characteristic's whit surgical tool's.thank's

[BlakCr0w]

I don't think this type of metal is adequate for surgical purposes...Not as good as stainless steel anyways.

[CharlesM479]

Surgical tools are made in PM all the time.

Sintering can be done with induction or microwaves. Not your microwaves but microwave furnaces.

Your not seeing atoms. You are seeing fine grain powder. Its about like sugar or salt.

[Faizan127]

yeah i was reading foundation but it's cool here

[seneca67]

I wonder if sinterring can be done with induction, or microwaves?

[boatoflol]

HAhah, you´ll see. Just put a spoon or some other matal thing into your microwave and put it on.

Induction may be a solution.

[seneca67]

ty, i have seen some amazing thing recently with induction, and microwaves. This could turn into a new cottage industry. :)

[boatoflol]

I dont know if its efficient enough. Some should do experiments.

[mraheem2004]

thanx

Now I can understand the book of Randell German ((Powder Metallurgy))

[JustMakingComments]

First time seeing atoms balls fusing together...

[DrMetan]

what you see is no fusing of single atoms. The animated spheres are metal powder consisting of millions of atoms (metal structure).

Reading the book is much easier now. thanks!
