FAQ
Frequently Asked Questions
Which substrate grade should I select — Grade 1 or Grade 2?
Grade 1 is selected where forming or drawability is required. Grade 2 is selected where structural rigidity is the controlling criterion. Substrate form is ASTM B265 strip or plate for formed substrates, and ASTM B348 bar for rod and stem substrates. Final grade selection is confirmed at DFM review.
Which coating should I select for chlorine evolution?
RuO2-based coatings are used for chlorine-evolution environments. Final coating selection depends on your electrolyte chemistry, current density profile and expected service life, all of which are reviewed at DFM.
Which coating should I select for oxygen evolution?
IrO2-based coatings are used for oxygen-evolution environments. Where inertness is required, platinum coating is an alternative. Final coating selection is reviewed against your electrolyte and operating parameters at DFM.
Do you attach lead wires or tabs to the anode?
Yes. Lead wires or tabs are attached by joint method selected per service environment, with seal method and insulation applied per electrolyte chemistry and current load. Wire material, cross-section, insulation type and seal method are confirmed at DFM.
Can you re-coat an existing titanium anode?
Existing titanium anode substrates can be stripped and re-coated, subject to substrate condition at intake. Stripping method is selected per substrate condition and coating chemistry; intake inspection is performed before re-coating is scheduled.
What documentation is issued with the finished anode?
A material test certificate (EN 10204 3.1), dimensional report, coating record and lot trace are issued with each lot. Additional documentation scope is confirmed per PO.
Standards note. Material specifications (ASTM B265, ASTM B348) cover raw stock scope. Finished-part acceptance criteria are governed by your drawing and PO.
