Thanks for the update. This is strictly a view from manufacturing: Tungsten, at these prices, will start to see a push back. There are some metals that are just too abrasive and Tungsten Carbide is necessary for cutting. However, there are a lot of other cases that Tungsten Carbide is preferred, but not necessary. There are some edge cases where it may make sense to do an entirely different (grinding, water jet, etc.) process than cutting.

McMaster Carr sells .375” diameter with .375” shank Carbide endmills for $43.49 each. McMaster Carr sells that same end mill, in Cobalt Steel, for $22.54. That price difference is enough that the shortened life of Cobalt Steel is tolerable.

The other end of pricing is Cubic Boron or TiSiN. Tungsten is moving up in price enough that the economics of Carbide becomes questionable versus CB or TiSiN tool inserts.

All metal cutting tools wear and eventually become unusable due to the very high temperatures at the cutting edge. Simply slowing the cutting speed down reduces tool wear. Using better (more expensive) coolant is also a way to prolong tool life. Both of these choices reduce productivity, but it is worth it when Carbide reaches a certain price point.

Well summarized mate, I have come to the same conclusions as you and staying long and strong. This has the smell of ultimate price spike in the air ("what uranium should have been or will be one day"), with no meaningful inventories left and a large mismatch between supply (nothing meaningful coming online at short notice) and demand (panic buying from manufacturers, almost no demand destruction via substitution & huge defense spending + now middle east conflict escalating). Wouldn't be surprised if we see $5,000/MTU down the track.

Am here for the EQR re-rate and if we halfway close the gap to the Almonty valuation + EQR keeps executing + tungsten price keeps rising, then there is still a fair bit of meat on this bone left.

Glad you joined the ride in a very timely manner.
