ASTM B169 specification establishes the requirements for UNS Alloy Nos. C61300 and C61400 aluminum bronze sheet, strip and rolled bar.
The products made to this specification are commonly used for drawing, forming, stamping and bending applications and are not intended for electrical applications.
ASTM B169 specification is the companion to SI Specification B 169M; therefore, no metric equivalents are presented in this specification.
NOTE 1-The products produced under this general specification may be used in many applications where the individual requirements may be too specific to be determined by normal physical or mechanical testing. Therefore it may be advisable for the purchaser to submit samples or drawings to the manufacturer in order to be assured that the product furnished is suitable for the intended application.
NOTE 2-Refer to Specification B171 for plate product.
