Description
CopperPlus is composed of a 10% thickness of copper metallurigically bonded at the atomic level to an 80% core of Type 430 stainless steel. It is fully annealed. CopperPlus has a 25 1/2-year warranty, but is designed to offer more than 60 years of service in even the most hostile environments. Installation
CopperPlus is designed to be installed in accordance with recognized construction sheet metal practices. It can be cut, formed, soldered, welded, riveted, and nailed, using conventional sheet metal methods.
Forming
Fully annealed CopperPlus forms in similar fashion to other soft construction metals. It can be bent flat on itself (180 degree bend - zero radius) at all standard gauges.
Soldering
CopperPlus is readily soft soldered using 50-50 or higher tin content solder. Mild fluxes for soldering copper are used. Smaller cooler irons can be used, resulting in faster soldering speeds.
Cutting
Conventional hand and power tools are used. For best results, cutting edges should be kept sharp and shears should be closely aligned.
Mechanical Fasteners
All mechanical fasteners (nails, screws, bolts, rivets, etc.) used should be made of copper, stainless steel, brass, or bronze.

Sizes
CopperPlus is available in thicknesses of .003" to .060" in coils or cut-to-length sheets up to 24" wide.
Maintenance
Final cleaning is not normally required except to remove solder flux residues, which form a premature green patina in affected areas. When desirable, final cleaning usually can be accomplished with a detergent and water. In the case of heavy deposits, a mild abrasive cleanser is recommended. No routine maintenance is required.
Specifying CopperPlus
CopperPlus is a superior product for any concealed, exposed, or special application where metal is indicated or required by the design. Simply indicate the location and configuration in the usual manner and identify the material as CopperPlus.

Design Compatibility
CopperPlus is compatible with most building material. Contact with aluminum or carbon steel should be avoided because deterioration may occur when these materials come into contact with copper.
