Note: ASTM properties based on 1/16″ sheet thickness except ASTM F38, which is based on 1/32″ sheet thickness. This is a general guide only and should not be the sole means of accepting or rejecting this material. The data listed here falls within the normal range of product properties but should not be used to establish specification limits nor used alone as the basis of design.
