Antenna Spring

Antenna Spring

Antenna Spring

(OP)
We are manufacturing a antenna spring made of music wire per astm a228.  The customer is asking for a coating to be placed over the material.  The spring will be used on a clock and will only be used in doors.  Does any one have any ideas of a plating or coating to use?  I have attached a drawing of the spring in question

Thanks in advance
 

RE: Antenna Spring

Why does the customer want a coating?  Corrosion resistance?  Apearance?  Other?  That will have a large influence on the coating selection.

Cory

RE: Antenna Spring

If it can be a metallic coating, how about coated wire before spring making?  Several suppliers provide zinc coated wire, and Bekaert makes Benzinal (Zn + Al) and Benzalplast (Zn + Al + PET plastic).  Or, you could coat the finished springs with a coating like Magni 565 or one of the Doerken Delta series coatings.  Colors are available with some of these also.
