Tungsten & Tungsten Carbide Alternatives 4

[blueandwhiteg3]

Can anybody suggest alternative metals/alloys with properties in terms of hardness, impact resistance, stiffness, abrasion resistance, etc. in the range of tungsten and tungsten carbide?

I'm specifically looking for a metal or alloy here, not a ceramic or composite. Cost is not a major issue. Lower density would be nice.

Molybdenum runs a bit soft for my tastes.

TVP is absolutely right with his comments. No single alloy in the world has it all. With every single alloy there is always a balancing act between a number of competing and mutually exclusive properties and characteristics. Depending on a particular application, as well as cost restrains, we chose an alloy that is optimal for the application at hand.

Something no one has mentioned is the Manganese Steels, in this case Manganal, for whatever the end product is. These steels are readily available and can be easily repaired by welding.

unclesyd,star to you for this gentle reminder. How could I betray this material which provided me all the business once.

This is really interesting, although I would really like to see If I can get into alloys with a liquidus of 2330° F or less.

Look at the bottom of the page in the referenced link in my last post. It concerns TC embedded hammers. Depending on the configuration of your part this might also be a way to approach the problem.

There are others that embed TC into weld metal on a very small scale.

Still shooting in the dark, not enough information is given to open up more avenues of approaching the problem.

Combining the postings by TVP and calphad and if the component is amenable one might like to look at the Ferro-Tic line of TiC materials.

There are other possibilities available if a little more information was available.
