Selection / quote / sample ↗Selection questions
Can one passivation product treat all metals?
Do not assume interchangeability. Match separate models to die-cast aluminium, stainless steel and magnesium, with trials against alloy, finish and corrosion criteria.
Is cleaning required before passivation?
Assess oils, polishing wax and surface condition, then establish pretreatment, rinsing and drying against the selected model. Confirm conditions separately for each metal and passivation system.
What should I provide for sample evaluation?
Share alloy grade, contamination, equipment, available temperature, downstream requirements and component photos, together with finish and acceptance criteria.
Can website trial parameters be used directly in production?
Website conditions support initial selection. Obtain model-specific TDS and SDS and validate actual components, equipment, water quality and downstream requirements before production. Do not interchange model parameters.
