thickness (0.0003 inch). Unless otherwise specified in the contract or order, cadmium coatings
shall be post-treated with the conversion coating required by the cadmium coating specification.
3.6.1.1 Cadmium coatings shall not be used for the following applications:
a. Parts that may be in contact with hydraulic fluids, fuels, lubricating oil, and other
petroleum based fluids.
b. Parts in frictional contact where gouging or binding may be a detrimental factor.
c. In confined spaces, in the presence of organic materials that give off corrosive or
damaging vapors.
d. On titanium parts or fasteners. In addition, cadmium plated parts, including
interference-fit fasteners and press-fit bushings, shall not be used in contact with
titanium. Under certain conditions, titanium can be embrittled by contacting
cadmium components. Embrittlement has been determined to occur in cadmium
plated titanium parts at temperatures as low as 150° F.
e. Parts that will be subsequently soldered.
f. Components that will come into contact with graphite composites.
g. Parts that will be exposed to temperatures above 450° F (232° C).
3.6.1.2 Parts containing recesses or entrapments. Parts containing recesses or entrapments
that may retain cleaning and plating fluids shall be vacuum cadmium plated in accordance with
SAE AMS-C-8837. Additional protection, such as an organic coating system, may be required
for recesses that cannot be coated by these methods.
3.6.2 Cadmium-titanium plating. Cadmium-titanium plating shall be in accordance with
MIL-STD-1500.
3.6.3 Nickel-cadmium plating. Nickel-cadmium plating shall be in accordance with
SAE AMS2416.
3.6.4 Tin-cadmium coatings. Electrodeposited tin-cadmium shall be in accordance with
MIL-P-23408. Other tin-cadmium coatings shall be in accordance with SAE AMS-C-81562.
3.6.5 Tin and tin-lead plating. A plating of tin or tin-lead may be used on parts that are
subsequently soldered. Tin plating shall be applied in accordance with ASTM B545 and tin-lead
plating shall be in accordance with SAE AMS-P-81728.
3.6.6 Aluminum coating. Aluminum and aluminum alloy coatings shall be used where the
properties of these materials present distinct protective advantages in comparison with other
coatings and platings at temperatures greater than 450° F. Aluminum and aluminum alloy
