A new era for sustainable corrosion protection
Hiron is a cyanide-free zinc iron electrolyte that does not contain nickel. When combined with tried and tested Atotech post-treatments, this zinc iron coating provides outstanding corrosion protection, performing excellently in the most stringent corrosion tests, such as PV1209 cyclic corrosion, neutral salt spray, and Ehra-Lessin corrosion tests.
Hiron’s alloy range can be adjusted between 12 and 15% iron content to fit customized performance specifications. It is heat resistant and creates a silver appearance on par with zinc nickel. With an iron content of 15%, Hiron exhibits a hardness of 500 HV.
Hiron is suitable for silver and black coatings, and offers an even thickness distribution. Hiron is also an excellent adhesion promoter for organic top coats or e-coatings. It passes the crosshatch test with flying colors and delivers a creepage superior to zinc nickel or other electrolytic zinc solutions.
Hiron and zinc nickel deposits have comparable friction windows due to their similar hardness range. When applied in combination with Atotech sealers, also used for zinc nickel applications, Hiron electrolytes achieve friction results identical to those of zinc nickel.
What inspires us
Why we developed Hiron
Due to regulations such as RoHS, ELV, WEEE or REACH, the need for sustainable surface finishing is continuously growing. The formal classification of nickel as a toxic substance has compelled many industries to seek safe and effective substitutes for nickel-based coatings.
The Hiron zinc iron electrolyte is free of nickel and cyanide. Due to its comparable deposition properties to zinc nickel coatings, Hiron can substitute zinc nickel electrolytes and significantly improve product sustainability. The zinc iron electrolyte already meets the requirements laid out by many industries requiring high corrosion resistance.
