General Information:
Pressure sensitive adhesive (peel and stick) on one side of the material permits quick and easy prototype and shield fabrication by hand. The material exhibits an aesthetically clean and bright metallic surface. The annealing process leaves the alloy "dead soft" so it should be protected from denting and scratches. Bending is possible, but gently rounded bends are favorable to sharp creases and acute angles. Great care should be taken to avoid heating this material above 400C since heating will affect the grain size and deteriorate shielding properties. Unfinished edges may be sharp so care should be taken during handling, and proper finishing of edges is required to protect end user.

Maintenance:
Because of its high nickel content, this alloy is highly corrosion resistant. Cleaning is simple with a soft cloth, or you can use mild soapy water (be sure to rinse well and dry). If required for cosmetic purposes, this material can be spray painted or adhesive veneers may be applied.
