Aluminum (typically .003”, .005”, .020”, .032”, 063” in thickness with a anodized mill surface finish) is the most common choice for most commercial and mil-spec applications. Reflective and other surface textures are also available, as are a broad range of anodized colors. When the square feet of aluminum required in a job is substantial, non-anodized material can result in important cost savings. Of course non anodized material will “weather” where not printed, etched, or covered with a gloss or matte clear coat. Aluminum material is also available with a thick white painted surface. This option is a particularly good choice where bright graphics are desired on a metal plate since the white surface allows colors to really “pop”.
Stainless Steel (typically .003”, .006”, .008”, .018”, .029”, .048” in thickness and 301 or 304 alloy; 2b finish) are the most common stainless steel options. Stainless steel is preferred in food machinery or other applications where caustic cleaners or other chemicals with PH>7 come in contact with the nameplate. Anodized aluminum is a poor choice in these environments as caustic materials immediately attack the aluminum.
Brass (typically .032”). Etched brass is commonly used in marine applications (if marine grade stainless is not) because of it’s strong resistance to salt water. Brass also is selected for architectural, vehicle and other applications because of it’s appearance, and it’s perceived association with the highest quality construction.
