Although the Association believes that its compilation procedures are reliable, it does not warrant, either expressly or impliedly, the accuracy or completeness of this information. The Aluminum Association assumes no responsibility or liability for the use of the information here

4、 the interim between publication and proposed use. i FOREWORD This is the third edition of The Aluminum Associations Registration Record for Components of Clad Aluminum Alloy Products. The compositions of certain specific clad products are also covered in the Associations publication, “Aluminum Stan
5、dards and Data”. This Record will be maintained by the Associations Technical Committee on Product Standards and it will contain all clad products registered with the Association, as well as a list of those that have been deactivated. Additions will be made as required and clad products will be inac
6、tivated (see list of inactive clad products) when no longer in commercial use. Proposals for additions, inactivations or reactivations by any company will be considered by the Technical Committee on Product Standards. Some of the alloys or clad products may be the subject of a patent or patent appli
7、cation, and their listing in this Registration Record is not to be construed in any way as the granting of a license under such patent rights. ii DESIGNATIONS FOR CLAD PRODUCTS Clad products described in this Registration Record are composite wrought aluminum alloy products having a metallurgically
8、bonded aluminum or aluminum alloy coating which is applied for purposes such as: corrosion protection, enhanced finishing response, or brazing. The basic description of a clad product includes the designation “Clad“ or “Alclad“, prior to the core alloy designation and the product form. The term “Alc
9、lad“ specifically refers to clad products where the cladding alloy is anodic to the core and, as a result, provides corrosion protection for the core alloy. The term “Clad“ is applied where cladding is used for a functional reason other than corrosion resistance. *Exception: In some cases, most nota
10、bly with brazing sheet products, clad products are assigned arbitrary numeric or alpha-numeric designations. Example: No. 21 Brazing Sheet In these cases, each designation identifies a unique combination and configuration of cladding and core alloys. Odd and even numbered designations indicate one s
11、ide clad and two side clad products respectively. The following information describes a clad product and is necessary to complete the clad product registration record: 1. Product form 2. Component alloys core alloy cladding alloy 3. Cladding location sheet and plate: both sides (assumed unless other
12、wise indicated) or one side tube: inside, outside, or both 4. Cladding thickness, nominal and average cladding thickness by location for each range of total product thickness, expressed as a percentage of the total composite thickness or cross-sectional area. sheet and plate: percent of total thickn
13、ess on a side tube: percent of total wall thickness wire: percent of total cross-sectional area The first clad product registration, for a given core alloy and product form, shall be designated as the original clad product registration and identified as: Clad “Core Alloy“ and “Product Form“, or Alcl
14、ad “Core Alloy“ and “Product Form“. Examples: Clad 1100 Reflector Sheet Alclad 2024 Sheet Alclad 3003 Tube iii DESIGNATIONS FOR CLAD PRODUCTS (Continued) Additional clad product registrations and descriptions will be assigned for a given core alloy and product form on the basis of variations in the
15、cladding alloy, cladding location, cladding thickness, or a combination, as illustrated in the following: Cladding alloy Example: Alclad 7050 Sheet and Plate (original clad product registration) 7108 Alclad 7050 Sheet and Plate (modified clad product registration) Cladding location Example: Alclad 7

17、clad product registration) iv REQUIREMENTS FOR REGISTRATION OF CLAD PRODUCTS 1. Any company may submit a proposal for registration, inactivation, or reactivation of a clad product to The Aluminum Associations Technical Committee on Product Standards for consideration. 2. The chemical composition lim
18、its for cladding and core alloys must be registered with The Aluminum Association. 3. The clad product shall be offered for sale currently and shall have been sold within the 12 months immediately preceding the date of registration request, in both cases in commercial quantitiesa-d. Such sales shall
19、 have been made to external users/customers (i.e., internal use and/or transfer of a clad product within a company does not meet the stated criteria). a. The clad product has undergone bona fide mill production and is NOT a “laboratory“ scale volume used for evaluations or experimental purposes. b.
20、The clad product is cast and fabricated in standard production facilities and is NOT a one-time production. c. There is an expected and ongoing commercial demand and/or need for the clad product d. The clad product must be purchased and sold in a standard business context which indicates that the pr
21、oduct is actually “sold“ and not “given away“ for uses such as promotional evaluations. 4. Sufficient information must be submitted to designate the product in accordance with existing practices. 1 COMPONENTS OF CLAD PRODUCTS Component Total Thickness Cladding Thickness per Side Alloys of Composite
