5、003-10 Reaffirmed 2014-04 Superseding AMS4611G Brass, Naval, Bars and Rods 60.5Cu - 38.7Zn - 0.8Sn Half Hard (H02) (Composition similar to UNS C46400) RATIONALE AMS4611H has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE: 1.1 Form: This specification covers a copper alloy (
6、naval brass) in the form of bars and rods. 1.2 Applications: These products have been used typically for automatic screw machine parts, but usage is not limited to such applications. These products have better corrosion resistance than AMS 4610 but are less readily machinable. 2. APPLICABLE DOCUMENT
7、S: The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been can
8、celled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications: Available from SAE, 400 Commonwealth Drive, Warrendale, PA 15096-0001 or www.sae.org.
