Mast Finishes

Mast Finishes

Will-Burt offers a variety of finishes for aluminum and composite masts. These advanced finishes are designed to prolong the life of the mast and reduce maintenance. They have been field proven around the world from the high temperatures and dust conditions of the harshest desert regions to the constant rain and salt exposure of the coasts. Custom finishes and colors can also be created to meet specific program requirements. Disclaimer: The below color chart is for reference only and is not to be used for final color matching.

Black Anodize w/ Electrolytic Color		AN08	Black anodize is an economical color option that provides the same level of protection as the standard commercial clear anodize aluminum mast finish and meets MIL-A-8625, Type II with Electrolytic Color, a two-step process.	N/A
Chromate Convert		CH01	MIL-DTL-5541, Type I, Class 1A provides maximum protection against corrosion, whether painted or unpainted. This is a relatively thick coating has higher electrical resistance and is used as a final finish or pre-treatment to paint or powder coating and covers chemical conversion coatings formed by the reaction of chemical conversion materials with the surfaces of aluminum and aluminum alloys. The specification is approved for use by all departments and agencies of the United States Department of Defense (DoD) but is not RoHS compliant.	N/A
Chromate Convert		CH02	MIL-DTL-5541, Type II, Class 3 provides good protection against corrosion, whether painted or unpainted. This is a thinner coating has lower electrical resistance and is used as a final finish or pre-treatment to paint or powder coating and covers chemical conversion coatings formed by the reaction of chemical conversion materials with the surfaces of aluminum and aluminum alloys. This coating is RoHS, ELV and WEEE compliant.	N/A
Electrodeposited Cadmium Plating		PL01	Electrodeposited Cadmium Plating serves as a great paint base while improving aesthetic value and prolonging the life of the base metal due to an increase in corrosion resistance. The Type II classification specifies plating with supplementary chromate treatment to increase corrosion resistance and Class 1 specifies a minimum thickness of 0.0005”. SAE-AMS-QQ-P-416 is the federal standard for Electrodeposited Cadmium Plating and it is best used in harsh environments and aerospace applications.	N/A
Black Oxide		PL02	Black oxide meets MIL-DTL-13924 specification and is a conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder used to add mild corrosion resistance, for appearance and to minimize light reflection. One of its advantages over other coatings is its minimal buildup.	N/A
Electroless Nickel Plate		PL03	Electroless Nickel Plating, measuring 0.0005" thick can be plated over a wide variety of metals including aluminum, titanium, mild steels, stainless steel, hardened steel, copper, brass, and zinc diecast. Electroless nickel provides a hard, wear resistant surface and improves resistance to galling.	N/A
Passivate		PL04	ASTM-A967 is the standard specification for chemical passivation treatments for stainless steel. The passivate process removes foreign metals and oils, usually from machining from the surface of stainless steel. Passivation purifies the surface of a machined part, therefore improving corrosion resistance without changing the dimensions or overall appearance of the part.	N/A

Application Examples
Part number 5176401 defines a part with drawing number 51764. The part number 5176401 potentially defines multiple finish variations when a suffix is added to the part number.
A part number of “5176401-AN01” means the part is to be clear anodized per Table 1.
A part number of “5176401-AN02” means the part is to be black anodized per Table 1.
The finish suffix can be applied to top level assembly part numbers. This defines the finish on all appropriate sub-component parts within the assembly.
A part number of “710390690-AN05” means the part is to be black hardcoated per Table 1.
