Sintered Porous Stainless Steel & Titanium Plates
Sintered porous plates and sheets in 316L SS or Pure Ti. Flat format for sparger plates, electrode substrates, flow distribution, and filter media blanks.
SS / Ti Porous Plates
Titanium plates up to 600 × 400 mm; SS plates up to 300 × 300 mm; thickness 0.5–20 mm (Ti) or 0.5–10 mm (SS). Plates can be cut to precise shapes — round, rectangular, or irregular — by wire-EDM, laser cutting, or milling, with hole patterns, slots, or custom profiles machined after sintering.
For PEM electrolyzer applications, porous titanium plates require cell-specific evaluation of porosity, pore size, electrical contact and surface finish. Sintering alone does not establish resistance to hydrogen embrittlement under cathodic charging. Confirm electrode potential, electrolyte, temperature, coating requirements and acceptance tests before selection.
For electrocatalysis research, plates are available with a ruthenium-iridium oxide (Ru-Ir, MMO) coating or platinum coating — typically 8–12 µm on a 100 × 100 mm format — for bifunctional oxygen and hydrogen evolution catalyst studies. Coating is applied on customer request and is quoted separately.

What Sets These Porous Plates Apart
Ti Plates for PEM Electrolyzer
For PEM electrolyzer applications, porous titanium plates require cell-specific evaluation of porosity, pore size, electrical contact and surface finish. Sintering alone does not establish resistance to hydrogen embrittlement under cathodic charging. Confirm electrode potential, electrolyte, temperature, coating requirements and acceptance tests before selection.
Precision Cut to Drawing
Waterjet and wire-EDM cutting to complex shapes, with hole patterns, slots, and machined profiles. Tolerances to ±0.1 mm.
Large-Format Ti Plates
Titanium plates up to 600 × 400 mm — significantly larger than SS plates — available in single-piece format without joins.
Porosity and Surface Records
Porosity measurement and Ra surface finish records available on request for PEM-grade titanium plates.
Catalyst-Coated Plates (On Request)
Ru-Ir oxide (MMO) or platinum coating available on titanium plates for electrocatalysis research. Specified and quoted separately on customer request.
Full Material Documentation
Mill test reports, chemical composition, and CoC available for every batch. Dimensions and porosity inspection records on request.
