Frequently Asked Questions

Technical FAQ

What materials can be coated?
Steel, stainless steel (304/316), aluminium alloys, copper, brass and titanium. The optimum coating method is recommended based on the substrate.
How is coating thickness determined?
Coating thickness is agreed with the customer based on operating conditions, corrosion class, wear expectations and aesthetic requirements. Standard: nickel 5–50 µm, hard chrome 20–200 µm.
What standards apply to the coatings?
DIN EN ISO 4527 (electroless nickel), DIN EN ISO 6158 (hard chrome), DIN EN ISO 1456 (decorative chrome), MIL-DTL-5541 (alodine). Customer-specific standards are also accommodated.
Is surface preparation required before coating?
Yes. Mechanical polishing, chemical cleaning and activation are applied before coating for optimum adhesion. All services are provided under one roof at Innox-Engineering.
Is there a minimum order quantity?
Prototype and R&D orders are accepted from 1 piece. For series production 50+ pieces are recommended. Individual conditions can be agreed directly with Özgür Kılıč.
