At the beginning of June 2007, the European Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) came into force.

We have evaluated all of our products and concluded that at present, no parts that we process or chemicals that we purchase, contain any substances that require REACH registration.

As a company concerned about our environment, we are active in limiting our use of chemicals. We work closely with our chemical suppliers to track our Material Safety Data Sheets and to ensure that our chemical usage and other materials conform to all regulations.

If, in the future our monitoring indicates a change in REACH status for any product we supply to customers, we will inform those customers accordingly and register that chemical with REACH. In addition, we can confirm that all products supplied by us do not contain any SVHC’s (Substances of Very High Concern). Apart from and classed as special processes *

Namely :-

Alocrom 1200*

Hexavalent Yellow passivation for Zinc Plating*

We do offer alternatives to Alocrom1200, namely Surtec 650V and Iridite NCP . We can offer historic performance data by request if required for assessment.

Hexavalent Chromate passivation used within our Zinc plating process is still in use (Reducing), however, our alternative trivalent passivation systems have been in use for some years now. We are working towards removing the Hexavalent passivation systems over the next 12-24  months intending to further educate and clarify the confusion that our customers are experiencing through the transition.

Further information regarding REACH can be found here.


The following letter was sent to all our customers advising them about the ELV, WEEE and RoHS directives.

11″ April 2005
Electroplating/Metal Finishing Legislative changes which affect your companyIncorporating :-
1. Automotive Industry (E.L.V.) End of life vehicles Directive
2. Electrical and Electronic (W.E.E.E) Waste Electrical and Electronic
Equipment Directive.
3. (R.O.H.S) Restriction of use of certain hazardous substancesDear Customer,The above legislation comes into force in July 2006. Wc are hearing rumours that some of the major Electronics industries are enforcing the (W.E.E.E) directive as are some of the Automotive sectors (E.L.V) both of July 2005 just 8 weeks away. With this in mind, I would kindly ask you to obtain the necessary information from your own customers to understand their requirements ready for the full changes as and when necessary.In short, our connection in this matter is to supply you Electroplated parts, which conform to all of your customers requirements.Finishes which will be effected from Diamond Metal Finishing’s point of view will be directly linked to Passivation. As we supply Zinc Plating, Zinc -Cobalt plating on steel and Alocrom conversion coatings on Aluminium products to you, there have been changes in the type of passivation wc will be allowed to supply. This will change from Chromium VI (Hexavalent) Passivate to Chromium III.(Trivalcnt) Passivate, as will the aesthetic appearance. There are three categories (colours) used at DMF which will be affected.Wc will continue to offer Hexavalent Passivation along side the new Trivalent until such time when all industry sectors have to conform to full legislation or demand falls to a none commercial basis.

I hope this has helped you regards to the respective changes which will directly affect your business. Careful thought must be taken when specifying the correct passivation as the new “Yellow” trivalent is 20 times more expensive to process as the present process, which could mean a potential 10% increase per unit and visually is very pale in colour as opposed to the deep gold/yellow you are presently used to. We would suggest for commercial parts that conventional Clear Trivalent be used as opposed to the “Yellow” where possible. Lacquers/Seals can be offered to increase the corrosion protection aspect.

Please feel free to contact me directly to discuss your requirements on 07973 380548 at any time. I will be pleased to advise accordingly.

Further information can be obtained from your local Environmental office or from their website.

Yours Sincerely

Steve Pendleton (Managing Director)
