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

**LINK**

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.
