Difference between nickel chrome plating and electroless nickel plating



We were using a metal part for an indoor application with nickel chrome plating but due to capacity constrain at our vendor place we are forced to get electroless nickel plated. Can you tell me the effect of this can you also let me know the differences between them and the process difference in this two different type of plating

I haven't checked this website in a while, but was wondering if you got an answer to your question. If not, I can provide some help for you on this. Is the application for something decorative, or "functional?" How thick was the nickel/chrome coating? The e'nickel process is auto-catalytic and requires solution temps. in the 180-190F range. No rectifier is used. Nickel/chrome is an electroplating process. In our industry, we use functional chrome and when nickel/chrome is needed, it's usually for thick applications (greater than 0.010 inch). Electroless nickel is usually applied much thinner than this (from 0.0005 to 0.002 inch). We use mid to high phosphorous e'nickel and the coating can be heat treated to make it harder than as-deposited.

Dear Mr Mohamad,

Both platings will meet your requirement for corrosion protection, but EN may offer you an advantage with uniform plating thickness, if your part is intricately shaped and cannot be successfully Nickel Chrome plated, or the finish of EN is acceptable even though your spec says NC. If youre still looking for a Vendor with spare capacity to do either of the platings, please oblige and get in touch with us by clicking on the link below.
