They're not going to work in every single valve system out there—the hardness is actually a double-edged sword if you're dealing with extreme impact loads that could chip the edge, but for most high-wear appliction these cemented carbide components hold up way better than steel alternatives.
So the main thing is the hardness rating of 87 HRA or higher, which is pretty much standard for this class, and that translates directly to the valve seats and balls lasting longer against abrasive particles or corrosive fluids that would eat through regular metal in weeks.
It basically handles up to 800°C without losing its structrual integrity, though we usually tell buyers to confirm their specific temperature range with the COA since the grain size (anywhere from micro fine to coarse) affects performance at the extremes.
The diameters range from 15.88mm to 57.15mm with tolerances from ±0.025mm to ±1.27mm depending on whether you need a polished surfce finish or just a blank for further machining—most buyers go with the polished option for sealing applications since it reduces operating torque noticeably.
Custom orders are possible with a negotiable MOQ of 10 pieces, but don't expect perfect stock on every odd size right away; we keep the 20mm and 30mm blanks in regular rotation, while custom diameters usually add 15-20 days or so to lead time.
Anyway, WC content at 85-94% with cobalt binder gives you better bend strength than straight tungsten carbide—typically 1400 N/mm² or higher—so it's a solid choice for mechanical transmission or precision instruments, just not ideal for applicaions with repeated point loading.
Our standard MOQ is 10 pieces, but we can negotiate if you need a smaller batch for prototyping or testing. Just let us know your needs.
Yes, we can supply a material test report showing ≥87 HRA hardness and ≥1400 N/mm² bend strength for each batch upon request. It's included in our quality documentation.
We hold tolerances from ±0.025mm for precision fits up to ±1.27mm for more general use. The exact tolerance depends on the size and your application—just specify when ordering.
We do—our standard polishing, blank, or coating options can be applied. The coating can enhance wear resistance at high temps, and we can tailor it based on your valve system's operating conditions.
We pack them in foam-lined boxes or sturdy cartons with individual slots to avoid scratching or chipping. For large orders, we use wooden crates to ensure safe transit.
