This is based on Alcoa free draw mini-die test. The free draw is designed to allow metal movement under limited constraints. Production tooling should generally yield lower earing results depending on clearances, standoffs, gaps or draw reductions. SURFACE Supplied as mill finish, with appropriate reoils, and as such is not degreased.

Consult your Alcoa representative to determine which product is suitable for your intended use. • All RPD packaging materials comply with the requirements of the CONEG model legislation [and the applicable provisions of European Council Directive 94/62/EC], regarding the presence of lead, mercury, hexavalent chromium and cadmium. Specifically: – None of the four metals are added intentionally. – The total concentration of incidental amounts of the four metals is below 100 parts per million (ppm). • Based on our present knowledge, these products do not contain materials known to the State of California to be carcinogenic or reproductive hazards at levels which would warrant labeling under California's Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). • Epoxy Coatings on RPD end stock for food contact comply with 2002/16/EC • Commercially available spectrochemical standards, traceable to the National Institute of Standards and Technology (NIST) and appropriate to the alloy supplied, are used to standardize and verify the accuracy of compositional analysis.
