Has anyone used Tungsten Disulphide (WS2) it looks promising for the lubrication for my flash steamer.


Moly and graphite solid lubricants have been used with moderate success but this looks an interesting alternative for the highly stressed components.

Any practical advice welcomed.

It might solve a few problems on your boat Paul, also looks like a good cutting lubricant. Ian S C

Try it and report, Paul!

I am interested in this (for another purpose) and wanted to make an order. But I was very p...d off when I saw that they send it with Fedex. Value of good £ 11.21 (without VAT); Fedex Economy £ 34.04, Fedex Priority £ 27.37 (!!!) . Delivery time difference is 2 days...
What's economy for them? What would Royal Mail ask for a 500 g parcel?
Well I have to admit it would be almost the same amount (£27 i mean) in the other directtion.

Greetings, Hansrudolf

I evaluated tungsten disulphide as a dry lubricant for steel textile machine parts some 40 years ago - in these circumstances it was about as good as flake graphite - but there was a disadvantage - possibly due to a problem in manufacture , it was quite corrosive towards steel - due, it seems to some free sulphur compound. It would be a terrible cutting tool lubricant - no coolant effect at all but a very good lube for sliding parts ie steel on steel or bronze. It can be "claggy" - I'd prefer graphite. I still have a few hundred grams lying about. I have used it to lubricate a Robinson engine -OK not great.

I don't have any history with this product but I haveused the chemical element on firearms when using them in very ccold weather hunting. I can verify it keeps the gun operating just fine at -20F ( I think the fox walked in to us as a method of suicide that night ). It didn't pickup dirt like oil and grease will and I still have a small stache around for cold weather shooting.

I think it's in Pauls link, they give the tool life extension of 500%, possibly used in conjuction with a coolant. Ian S C

Ian sc ,

I Googled the name and found the manufacturer in the USA , they will post to Australia so i would guess that NZ is likewise .
They wanted an address so they could Quote postage maybe they could use USPS and be a bit cheaper than FEDEX ?

Sources for WS2.

Archoil AR2400 sounds like a suspension of WS2 in oil . The stuff which I used years ago was solid ie 100% WS2 powder (about 300 mesh) . I vaguely remember that it was bought from Murex - a firm that sold/ made welding consumables based in London.

If you want a suspension there used to be - a long time ago - Acheson Colloids of Plymouth who sold graphite/ MoS2 etc as suspensions in water and/ or oil. They had a large range of similar products and perhaps WS2 also.
