7、on. This list is maintained by the Technical Committee on Product Standards of The Aluminum Association. The designations of these compositions were assigned in conformance with the system adopted by The Aluminum Association in 1954 and approved by the American Standards Association (now American Na

8、tional Standards Institute Incorporated) as an American Standard in 1957 (see American National Standard Alloy and Temper Designation Systems for Aluminum ANSI H35.1/H35.1(M). Additions may be made as required, and alloys will be deleted when no longer in commercial use (see table of inactive alloys

9、 printed on page 13). This registration record is not intended to address all regulatory requirements that may be imposed by local, national or international governing bodies. Regulatory requirements, which vary by region and end use, can further restrict the chemical composition within the register

10、ed limits. When applicable, inclusion of such requirements in the sales agreement is advised. Effective July/2015, the practice of registering experimental alloys has been discontinued and new experimental alloy designations shall not be granted. Some of the registered alloys may be the subject of p

11、atent or patent applications, and their listing herein is not to be construed in any way as the granting of a license under such patent rights.iCHEMICAL COMPOSITION LIMITS1,2 Only composition limits which are identical to those listed herein or are registered with The Aluminum Association should be

12、designated as “AA“ alloys. REGISTERED ALLOYS IN THE FORM OF xxx.0 CASTINGS, xxx.1 INGOT AND xxx.2 INGOT. DESIGNATION OTHERS12 Al Min.

Note 2“Others“ includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not specified in the registrat

Should any analysis by the producer or the purchaser establish that an “Others“ element exceeds the limit of “Each“ or that the aggregate of several “Others“ elements exceeds the limit of “

35、Total“, the material shall be considered non-conforming. Note 3Aluminum is specified as minimum for unalloyed aluminum, and as a remainder for aluminum alloys. 4. The term “original“ alloy as used in the Registration Record is defined based on the following guidelines: (a) Only one alloy set (xxx.0,

36、 xxx.1, xxx.2) in any alloy family is considered the “original“ alloy, and it is always used as the basis for registration of a modification. (b) All active and inactive alloys with no letter preceding the numerical digits are considered the “original“ alloys for each specific alloy family. (c) No d

37、esignation changes are made to any and all of the currently registered original alloys whether active or inactive. 5. The aluminum content for unalloyed aluminum made by a refining process is the difference between 100.00 percent and the sum of all other metallic elements together with silicon prese

38、nt in amounts of 0.0010 percent or more, each, expressed to the third decimal before determining the sum, which is rounded to the second decimal before subtracting; for unalloyed aluminum not made by a refining process it is the difference between 100.00 percent and the sum of all other analyzed met

39、allic elements together with silicon present in amounts of 0.010 percent or more, each, expressed to the second decimal before determining the sum. For unalloyed aluminum made by a refining process, when the specified maximum limit is 0.0XX, an observed value or a calculated value greater than 0.000

40、5 but less than 0.0010 percent is rounded off and shown as “less than 0.001“. For alloys and unalloyed aluminum not made by a refining process, when the specified maximum limit is 0.XX, an observed value or a calculated value greater than 0.005 but less than 0.010 percent is rounded off and shown as

41、 “less than 0.01“. 6. Applicable only if magnesium is an alloying element (i.e. has a registered minimum and maximum percentage). 17APPENDIX A USE AND ASSIGNMENT OF DESIGNATIONS USE OF DESIGNATIONS A.1 Alloy designations used in accordance with this Recommendation shall have chemical composition lim

42、its identical to the registered limits of that designation. A.2 Designations that could be mistaken for a designation described in the Recommendation (shown on page 16) shall not be used for unregistered aluminum alloys in the form of castings and ingot. A.3 Aluminum alloys in the form of castings a

43、nd ingot having chemical composition limits that differ from registered designations should be submitted for the assignment of a designation. ASSIGNMENT OF DESIGNATIONS A.4 Designations for a new alloy registration shall be assigned in the following order of precedence: A.4.1 Any proposed alloy havi

44、ng chemical composition limits that are identical to a registered designation shall use the registered designation. A.4.2 If a proposed alloy qualifies to be a modification of an original alloy, a designation for an alloy modification shall be assigned. A.4.3. A new original designation shall be ass

45、igned only for an alloy having different chemical composition limits which do not meet the requirements to qualify as a modification of any registered alloy. A.5 In considering requests for designation of a new alloy, the following criteria also apply: A.5.1 The complete chemical composition limits

46、shall be disclosed and judged to be reasonable and technically correct by the Technical Committee on Products and Standards. A.5.2 Any request for the registration of Ingot composition limits shall be accompanied with a request for registration of casting composition limits of the same designation,

47、with the exception of rotor and aluminizing ingot for which only ingot composition limits are required. A.5.3 The product (Sand, Permanent Mold, Die, Investment Casting, or any variation of these processes) shall be shown at the time of registration. Other products may pertain even when not listed.

48、APPENDIX B DEACTIVATION OF REGISTERED ALLOYS B.1 Designations in accordance with this Recommendation should be reviewed, at least once in every five years, to see if these alloys are still commercially active. If not, alloys should be proposed for deactivation. Any inactive alloy can still be reactivated when such need arises. APPENDIX C REQUIREMENTS FOR “SALE OF ALLOY“ AND “COMMERCIAL QUANTITY“ FOR PURPOSES OF REGISTERING ALUMINUM ALLOYS IN THE FORM OF CASTINGS AND INGOT C.1 Sale of Alloy The aluminum or aluminum alloy shall be offered for sale current
