It is also referred to as an autocatalytic process. Electroless Nickel is deposited by a chemical reduction process that reduces the nickel ions. Bright electroless nickel plating finishes are not recommended if parts are intended for flexure applications or will be bent or crimped in manufacturing operations subsequent to electroless nickel ama-c-26074.

Electroless Nickel Plating AMS-C Resources – Electrolurgy

Silver is commonly used for brazing, soldering, electrical contacts, electronics and medical applications. Thanks so much for asking, Ed: Improvements in wear resistance, corrosion resistance and hardness are achieved. Without the high and low current density found in electrolytic plating processes, Amd-c-26074 nickel can deposit into recesses without burning or having excessive thickness on the outer edges of a part.

As electroless nickel plating finishes become brighter, they become harder and less ductile.

Physical and mechanical properties vary considerably from one EN process to another depending on the phosphorus content, the formulation of the bath and both the pre-plate and post-plate treatments, yet all the EN coatings offer excellent deposit uniformity and superior corrosion protection. Now one feature of mil spec reform is that a number of cancelled military specs and standards ended up being reprinted in their entirety by various industry associations.

Please keep in mind that the thicknesses called out in the various specifications represent “thickness per side. Sulfamate Nickel Plating Sulfmate nickel plating produces a dull finish, which is better for engineering applications than decorative ones.


Electroless Nickel- Engineering Purposes Resistance to wear and abrasion are the main uses of electroless nickel plating in engineering applications. I hope you find this information helpful! Our nickel finishes have durable mechanical properties that allow them to sustain severe operating conditions.

EN plating is a chemical process that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power.

This enables the metal deposit to not be governed by flux density fields which tend to be non-uniform and can ans-c-26074 in uneven thicknesses of the deposits.

Unfortunately, the MIL-C was not cancelled at that point in time. The coating conforms exactly to the surface finish of the part so cosmetic finishes will be enhanced by the Electroless Nickel deposit.

Replacement spec for Mil-C-26074 (electroless nickel)?

AST offers matte, semi bright and bright silver coatings ranging from Electroless Nickel is a high quality engineering coating for corrosion resistance, hardness, lubricity, solderability and wear resistance. As you can see by my posting, the MIL-C has had a long strange history!

However, again there was resistance to this move. With two concurrent and identical specifications in force at the same time, confusion ran rampant. As it is also a hard metal with a high endurance to wear, nickel, when used in nickel plating services and combined with various levels of phosphorus, is often applied as a base layer for its leveling and smoothing characteristics and ability to provide greater wear and corrosion resistance.

The reaction is accomplished when hydrogen is released by a reducing agent normally sodium hypophosphiteand oxidized thus producing a negative charge on the surface of the part. The coating conforms exactly to the surface finish of the part so cosmetic finishes will be enhanced by the Electroless Nickel deposit.


The same customer says AMS [link by ed. Nickels ductility is dependent on the type of nickel plating used. Sulfamate Nickel plating provides a Nickel deposit for corrosion protection and is a functional highly ductile, low More Without the a,s-c-26074 and low current density found in electrolytic plating processes, Electroless nickel can deposit into recesses without burning or having excessive thickness on the outer edges of a part.

Adhesion on Beryllium and Aluminum. Supplier Requirements Privacy Policy Links. Advanced Surface Technologies specializes in high quality Electroless Nickel coatings.

Electroless Nickel on aluminum Please note that price shown is for minimum thickness. You can order through our website at www. Mil-C [link by ed. Thomas Industry Update Stay up to date on industry news and trends, product announcements and the latest innovations. Except for hydrogen embrittlement relief, no post ams–c26074 thermal treatment.

Silver is a cost effective solution for applications that require low contact resistance, high thermal conductivity and chemical stability. As the gold plating process requires a controlled environment, we perform operations in an area with independent air systems, separated from other plating processes. Leave a Reply Cancel reply Your email address will not be published. Since the plating process requires no electrical current, the coating produced is a very uniform structure that can be applied over various metals and substrates.

Tensile strengths range from 60, psi topsi, depending upon the conditions under which a bath is operated.
