Now approved for MIL-DTL-38999 and MIL- DTL-83513, Glenair’s Nickel-PTFE meets the need for a barrier plating cadmium replacement with excellent conductivity,
Hardcoat anodized aluminum offers greater wear resistance and better corrosion resistance compared to conventional anodizing. Typically employed when
Black anodized aluminum is an option for electrical connectors and accessories that do not require conductivity. Black anodized aluminum offers a modicum of corrosion
wear resistance and corrosion protection. This extremely durable finish is gun-metal gray. A proprietary preliminary undercoat is followed with a composite coating of electroless nickel phosphorus and polytetra- fluoroethylene (PTFE). Ni-PTFE is approved for the Joint Strike Fighter and offers excellent lubricity.
conductivity is not required, hardcoat aluminum offers good corrosion protection for marine and tactical applications. The resulting finish is a matte greenish-gray color. Hardcoat anodizing is an electrolytic process that creates aluminum oxide films by oxidizing the base metal in a sulfuric acid solution. The parts are immersed in a high-concentration sulfuric acid solution at 35°C. After anodizing, the parts can be dyed black (code GB).
protection and is relatively inexpensive. Anodizing is an electrolytic process that creates aluminum oxide films by oxidizing the base metal. While the resulting coating is neither harder nor denser than natural oxidation, it may be preferred due to its uniform color qualities. The parts are immersed in a sulfuric acid solution at room temperature. After anodizing, the parts are dyed black.

Plated composite connectors and accessories provide unsurpassed corrosion protection and excellent conductivity. Glass-reinforced or carbon-reinforcced thermoplastic is
If conductivity and EMI shielding are not required, unplated composites provide the best solution to corrosion protection. Glenair’s composite connector accessories are
Stainless steel offers unbeatable strength and protection from environmental stress if durability and corrosion resistance are more important than cost and weight. Typically
metallized and plated with electroless nickel (olive drab cadmium is another popular finish). Plated composite connectors and accessories have become the first choice for aerospace programs seeking to increase corrosion resistance and reduce weight.
ideally suited for use in harsh environments where even stainless steel parts can be attacked by corrosive fluids. Available in black (code XB) and brown (code XO).
found on aircraft engines, landing gear, geophysical equipment, armored vehicles and marine applications, passivated stainless steel is widely specified in throughout the interconnect industry. Also offered with nickel and cadmium plating for improved conductivity, stainless steel is an obvious alternative to cadmium if cost and weight are not an issue.
