Quality Metal Finishing & Nadcap Chemical Processing
Below is a short list of process specifications performed at ElectroLab. There are many customer specific specifications that are not included in this list. Please inquire here regarding other specifications. An asterisk indicates processes within the scope of our Nadcap accreditation.
MIL-A-8625, TYPE II, CLASS 1 & 2
AMS 2471
AMS 2472
Anodizing converts the surface of aluminum to a durable porous structure and provides good corrosion resistance. The porous structure readily absorbs dyes, allowing for a multitude of colors for the finished product. Primary colors available are black, red and blue. ElectroLab offers a wide variety of other colors. Inquire here for more information.
MIL-DTL-13924, CLASS 1 & 4
AMS 2485
MIL-F-495
Black Oxide coatings can be applied to steel, stainless steel and copper.
ASTM B633
QQ-Z-325
ASTM F1941
AMS 2402
Zinc plating is an inexpensive corrosion resistant coating. Chromates are applied to extend that resistance even further. These can be clear (silver), yellow, olive drab or black. Hexavalent chromates are not RoHS compliant. ElectroLab offers a clear RoHS compliant conversion coating for those applications which require such compliance.
ASTM B545
MIL-T-10727
Tin electroplating is typically used for electrical connectors and buss bars to add corrosion resistance, while maintaining good electrical conductivity.
MIL-DTL-26074
AMS-C-26074
ASTM B733
AMS 2404
Electroless nickel is a functional coating to provide good corrosion resistance. Because electroless nickel is deposited using chemical rather than electrical means, complex shapes can be plated evenly. This coating can also be baked to increase the hardness to nearly that of hard chrome.
QQ-P-416
AMS-QQ-P-416
AMS 2402
Cadmium plating is still used extensively in military and aerospace applications for its excellent corrosion resistance. A limitation of cadmium plating is hydrogen embrittlement of high-strength steels from the electroplating process. A post-plating bake is required to remove this hydrogen, and bring the material back to its original condition.
MIL-DTL-5541
AMS 2473
AMS 2474
ASTM B449
Aluminum conversion coatings are used to add corrosion resistance. It is also useful as a base for paint, improving both corrosion resistance and adhesion.
ASTM A967
ASTM B912
Electropolishing is an electrochemical method for polishing stainless steel and aluminum to a very bright finish. Highly decorative!
AMS 2700, METHOD 1
QQ-P-35
AMS-QQ-P-35
ASTM A967
ASTM A380
MIL-DTL-5002
Passivation is a method to remove free iron from a stainless steel surface (usually residual from machining tools) and create a thin chromic oxide layer on the surface of the material.
MIL-DTL-16232, TYPE Z
Zinc phosphate is used for corrosion resistance on steel parts. It also provides an excellent base for paint, improving corrosion resistance and adhesion.
AMS 2418
Copper plating commonly used as an undercoat in situations where enhanced adhesion for additional coatings of other materials is desirable, as it provides smooth and uniform coverage. Copper electroplating is sometimes used as a heat treat stop-off for masking, as it allows for selective heat-treating when needed.
