Solenoid armature design

Solenoid armature design

(OP)
Hello,

I would like to design a specific armature to replace the external housing of a solenoid used in a pull configuration.
I heard that the magnetic properties of the material is very important to keep the original magnetic force.
Can someone help me in the choice of material, and the associated heat treatment.
Thanks in advance.

RE: Solenoid armature design

There are many alloys used for solonide applications such as 430, 430F, 430FR, and a variety of other ferritic grades such as Ugiperm 12FM (a 12% Cr ferritic free machining alloy)and IMRY (an 18% Cr ferritic alloy).  Each alloy has their own unique magnetic properties and annealing temps for magnetic properties.  

You may want to check out www.uginestainless.com.  There are a couple of data sheets discussing some of these alloys.  You may want to call 800-523-3321 for additional information and availability.

RE: Solenoid armature design

I work for a solenoid manufacturer.  We typically use 12L14 steel for our armatures with no heat treatment.  It has great magnetic properties and is relatively cost effect.  If lead is not allowed in the application, you can try fully annealed 1215.  Due to the lead removal, we have been forced to replace the 12L14 in many of our applications, and I have found the annealed 1215 to be a valid substitute.  If those don't provide you with enough force, I would pursue the Carpenter Stainless suggested (430FR is the best I've found, but costly).
