Architectural Alloy Color Kits are available free to qualified users from MAC Metals. The kits include samples of up to three alloys in both polished and natural, mill finish that users or specifiers can use for new projects, or as a reference. Because MAC Metals extrusions are combined with other forms of copper alloys, the kits provide color matching confirmation. Color matching has been a complicated choice due to the metallurgy (cast vs. wrought) and available forms (extrusions vs. sheet, strip and plate). Since MAC manufactures these alloys with very tight chemistries, a perfect color match is assured bar to bar, and heat to heat. Alloy samples are available for any of alloys manufactured by MAC Metals including Architectural Bronze, Free Cutting Brass, Muntz Metal, Naval Brass, Nickel Silver, Brown Nickel Silver and Manganese Bronze, as well as proprietary Commercial Redd Metal and Rose Redd Metal. Brass, bronze and nickel silver extrusions combine natural colors with a host of performance properties that architects, contractors, manufacturers and fabricators acknowledge as they seek these architectural metals.
