Making sure the metal components of our products are able to resist corrosion has always been one of our highest priorities at Anthony Innovations. Unfortunately, the method traditionally used by the industry to do this – Hexavalent chromium plating – has been called into question over the last decade, with research showing there are health, safety and environmental issues that stem from its use.
This research has led to new restrictions on the use of Hexavalent chromium in many countries and is on the horizon for many more. Because of this we are transitioning the plating of all our metal components to the more environmentally friendly Trivalent Chromium process.
Why is Hexavalent Chromium being phased out?
While the use of Hexavalent Chromium plating has been a staple for the metal finishing industry for many years, in the past decade, there has been compelling research that questions the health, safety and environmental effects of using this type of chromium.
It produces several by-products which are considered hazardous waste, including lead chromates and barium sulphate. This has led to governments in Europe, China, and the U.S. to begin tightening regulations around its use, and many industries – especially the automotive industry – phasing out use altogether.
Can Trivalent Chromium perform?
Our 3rd party independent testing has shown that this plating can meet the AAMA 907 Corrosion testing standard. On top of this, our engineering team have run accelerated corrosion tests that show comparative results between the two processes.
Will I notice the difference?
There’s only one real difference you’ll notice: the colour. The new Trivalent Chromium has a clear finish rather than the yellow finish of the Hexavalent Chromium. Other than that, nothing else will be different. Our metal components will perform just as well and there will be no change in our pricing.
When does the transition start?
Specific dates are still being finalised, but expect to see the new plating appearing in your components before the end of the year.
