What it is and what it does. Sodium cyanide is the complexant of the cyanide copper, zinc, brass and silver baths. It dissolves the metal anode and keeps the deposit bright and well levelled on complex die-cast shapes.
- White crystalline briquettes; extremely toxic by ingestion and by inhalation of dust, and it releases hydrogen cyanide on contact with any acid.
- The free-cyanide to metal ratio is the main control parameter in every cyanide bath.
- Strictly segregated storage from acids, with an alkaline hypochlorite spill kit at the point of use.
Typical Use in a Plating / Finishing Line
| Item | Typical guidance |
|---|---|
| Cyanide copper bath | 60-90 g/L NaCN with the copper salt, free cyanide 7-15 g/L |
| Cyanide zinc bath | 40-90 g/L NaCN |
| Control | Free cyanide by silver nitrate titration; metal by titration |
| Safety | Never acidify. Never mix cyanide waste with acid waste |
Safety, Handling & Storage
| Item | Requirement |
|---|---|
| Hazard classification | Acute toxicity (GHS06) + aquatic hazard — releases hydrogen cyanide with acids |
| Personal protective equipment | Full-face respirator with appropriate cartridge, nitrile gloves, coverall; work only with ventilation and never alone |
| Spill / first aid | Never acidify. Contain with alkaline hypochlorite solution under trained supervision, then treat as hazardous waste |
| Storage | Locked, dry, ventilated store, strictly segregated from ALL acids; cyanide and acid must never share a store or a spill tray |
| Transport | Classified and packed according to IATA/IMDG for the hazard class; UN number and packing group stated on the shipping documents |

Specifying Sodium Cyanide for your line
Chemical fit is decided by the bath, not by the label. Send these four items and we confirm the operating window before you buy.
- Current bath: supplier, TDS and working concentration.
- Process: rack or barrel, temperature, current density.
- Substrate: zinc alloy, steel, brass or ABS.
- Complaint: the defect you are trying to solve, with photos.
| What you send | What you get back |
|---|---|
| Part drawing or sample | Compatibility check and recommended settings |
| Output target per shift | Capacity, tank or rack count, manpower |
| Finish spec with tolerance | Control points and acceptance tests |
| Site conditions (power, water, space) | Layout proposal and utility requirements |
Buying questions we answer most
Is the SDS available before we order?
Yes. SDS and COA are issued per lot. Tell us the destination country so the SDS is supplied in the required format and language.
Can we get a trial quantity first?
Yes. Trial packs are quoted separately and shipped with the analytical method, so your lab can verify the material against the current bath before switching.
What packing and shelf life should we expect?
Standard export packing in drums or jerry cans with inner liner. Shelf life depends on the product - typically 12 months in a closed container, stored away from heat and direct sunlight.
How is it shipped - is it dangerous goods?
Some products are classed as dangerous goods and need the correct UN packing and documentation. We confirm the classification and the shipping route before quoting freight.
Can you match a competitor's additive?
Send the TDS and a bath sample. We compare the operating window and analytical method, then run a Hull cell panel before recommending a replacement.
