Selection of the material

[hubihubi2]

Dear All,

I would like to ask you kindly for the advice in the material selection for the jig that is under construction. The requirements for the material are as follows:
- it has to be magnetic (the more the better),
- non-corrosive,
- machinable (milling operation),
- low-abrasive (this requirement could be fulfilled by covering working surfaces of the jig with protection film).

The jig will not be loaded with significant force. It will be working in ~20C temperature.

I hope for your help.

Thank you.

Regards,

Hubert

Magnetic (a magnet) or ferromagnetic (sticks to a magnet)?

How hard/strong does it need to be?

Without knowing more about your specific needs, a simple recommendation is 17/4 PH steel or 400 series .

Thank you all for your replies.

@1gibson - material would need be attracted by magnet (not magnetic itself).

@EdStainless - The jig will not be loaded with any significant force. It will be working in room temperature (~20degC). From material strength point of view only the regular mild steel would do as the material for the jig. The jig overall size will be approx. 300mm x 100mm x 60mm.

@arunmrao - thank you for your answer and advice .
