Will sandblasting remove nickel plating?
Sandblasting can improve the quality of the surface prior to gold, silver, copper, bright nickel, or electroless nickel plating. Instead of using chemicals sandblasting uses high-pressure air to pull an abrasive media through an air gun to shoot it at the metal surface.
Does acetone dissolve nickel?

How do you remove chrome plating from aluminum?
Use hydrochloric acid (muriatic acid). Hydrochloric, or muriatic, acid, is a strong, corrosive acid. In high concentrations, it can be used to remove chrome plating from metal objects. For removing chrome, an acid solution of about 30-40% concentration should suffice.
Can you paint over nickel plate?
Before the nickel plating will accept paint, it requires pre-treatment with a special acidic primer, formulated with the ability to etch durable metallic surfaces. Once you've properly conditioned the nickel-plated metal, it can be painted.
How to remove nickel from aluminum?
A. 50% tech grade sulfuric acid (66 degree sulfuric acid) and 50% water using electric will take off your nickel without hurting your aluminum. You can use a battery charger [affil. link to info/product on Amazon] as a rectifier. If the part has copper on it depending how much build is on the part it should remove it also. Nitric acid will do the job the same way without electric, make sure you don't put steel in nitric acid, bad* chem reaction. good luck
What acid to use to remove nickel from aluminum?
A. 50% tech grade sulfuric acid (66 degree sulfuric acid) and 50% water using electric will take off your nickel without hurting your aluminum. You can use a battery charger [affil. link to info/product on Amazon] as a rectifier.
Is plating more expensive than scrapping?
While this technique can salvage mismachined parts and thus be less expensive than scrapping them (plating may cost less than starting over), the plating would not be consistent enough in thickness nor inexpensive enough to achieve what you wish -- trying to plate to finished dimension will only increase costs, not decrease them.
Can nitric acid destroy alloys?
A. Concentrated nitric acid will do it without destroying the alloy in most cases. You will need proper protective equipment and good air flow as it will emit NOx! For small areas, try a swab. It will last for a minute or so and then you will need another swab. Properly dispose of your refuse. It is hazardous.
Can you sand blast finish off?
You can also sand blast, grind or sand the finish off.

Inaddition, you need to remove all nickel deposit before replating.
Why nickel plating aluminum?
Maybe you don’t have to because Nickel plating can significantly improve the properties of your aluminum parts. Some compelling benefits of nickel plating your aluminum parts are as follows, It improves the corrosion resistance. Gives an aesthetic look to your parts.
How is nickel electroplating done?
Nickel Electroplating is done by the reduction of cations by passing a current through an electrolyte solution of nickel. This deposits a thin layer of nickel over metals. But electroplating requires both the coating and the part to be metals.
What is the buffering agent for nickel plating?
In an all-sulfate nickel plating, only Nickel sulfate salt is used for preparing the electrolyte, and Boric acid is used as the buffering agent. Such type of coating is used when the anode is insoluble in the solution.
How is electroless nickel plating formed?
Electroless nickel plating is formed by an autocatalytic reaction. So, the coating is more uniform since there is no factor of uneven current density caused by the geometry of the part. The process for electroless nickel plating is described below.
What is nickel plating?
Nickel plating is the process of applying a nickel coating over metal parts by chemical reduction or electrolytic processes. Nickel Plating is an excellent surface finishing technique for both decorative and engineering purposes. Nickel plating aluminum parts is particularly popular among manufactures for its multitudes of benefits.
How does anodization work?
But they work a little differently. Anodization is done by passing a direct current through an electrolytic solution, which ads an oxide layer on top of the aluminum part.
What is the role of nickel in electroplating?
It removes impurities such as dirt, defect, or corrosion and protects the parts during electroplating. Then immerse the metal part into an electrolyte solution with nickel dissolved in it. Here the metal acts as the cathode, and the dissolved nickel acts as the anode.
How to get a plating off of a metal?
Brush the surface of the object vigorously with the toothbrush. Continue dipping and scrubbing with the toothbrush until the plating comes completely off.
What is chrome plating?
Chrome plating creates a shiny, reflective finish when in prime condition. Many antique items have been coated with chrome or nickel plating, and the owner may wish to restore it to the original finish through a plate stripping process.
What to put in a metal pot?
Put on proper safety gear such as respirator, splash goggles and protective gloves. Pour either acetone, ammonia or bleach into the large metal bowl or pot. Only use one of these chemicals; do not mix them.
How to remove plating from metal?
We have to de-plate and re-plate more often then we wish to remember. We send it back to the platers. They in turn use proprietary mixes to selectively attack the plating while leaving the base metal alone. Reverse plating is also another option. Proprietary plating removers are mixtures of acids, highly buffered, with selective chemicals to focus the acids on the platings and leave the parent materials alone. More than that, I cannot help, except to point you to some references. I remember several that covered stripping, but it was not my focus and I took no notes:
How to strip nickel?
Another very easy and quick way to strip nickel is using 100% nitric acid with 10% of acetic acid as inhibitor. The pieces should be baked to eliminate any trace of humidity to submerge them in the solution without to move it neither to take out it until it is stripped. Note, the pieces should be hung.
What is a proprietary plating remover?
Proprietary plating removers are mixtures of acids, highly buffered, with selective chemicals to focus the acids on the platings and leave the parent materials alone.
Is nickel round anode?
A. S Nickel Rounds are an anode material, so that indicates that your vendor electroplated nickel rather than electroless nickel. One relatively safe chemical option for stripping would be Metal-X B-9+.
