5、d 2010-11 Revised 2016-06 Superseding AMS3410J Flux, Silver Brazing RATIONALE AMS3410K revises 3.2.7 to specify a braze filler for flow testing that does not contain Cd and is a Five Year Review and update of this specification. 1. SCOPE 1.1 Form This specification covers a silver-brazing flux in th

6、e form of a paste. 1.2 Application This flux has been used typically for silver brazing nonferrous metals, excluding aluminum, magnesium, and zinc alloys, and ferrous metals including austenitic steels, at temperatures in the range 1150 to 1600 F (621 to 871 C), but usage is not limited to such appl

7、ications. 1.3 Safety - Hazardous Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibil

8、ity of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase ord

9、er 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 cancelled and no superseding document has been specified, the last published issue o

13、al Data for Hazardous Materials Furnished to Government Activities 3. TECHNICAL REQUIREMENTS 3.1 Material The flux shall be a blended mixture of uniform consistency containing not more than 35% water by weight. It shall not separate in the container to an extent that it cannot be restored to uniform

14、 consistency by stirring. 3.2 Properties The flux shall conform to the following requirements: 3.2.1 The flux, diluted with water as required, shall have acceptable fusibility and acceptable application and fluxing characteristics, and shall produce satisfactory brazed joints, of any type, on copper

15、 alloys, nickel alloys, and all types of steel, including corrosion-resistant alloys when used in conjunction with silver brazing filler metal. 3.2.2 During heating to 1,600 F (871 C), flux shall fuse at 1,150 F (621 C) or lower; when cooled from 1,600 F (871 C), flux shall remain in the liquid stat

16、e until temperature drops to 1,150 F (621 C) or lower. 3.2.3 Flux, placed on a U.S. Standard 40 mesh (425 m) sieve conforming to ASTM E11 and worked lightly with a brush, shall pass completely through the sieve. If the flux has partially agglomerated in the container, the flux may, before conducting

17、 the test, be warmed over a water bath until it has returned to its normal consistency. 3.2.4 Flux shall not produce, during use, a flame or smoke of sufficient intensity to obscure the work. 3.2.5 Flux shall be soluble in water at 175 F (79 C) or lower after being subjected to normal brazing operat

18、ions. 3.2.6 Flux shall have a shelf life of not less than six months; not more than thorough mixing shall be required to restore flux for use during that time. 3.2.7 When applied to AMS5510 corrosion-resistant steel, using AMS4763 filler metal and heated in air to 1300 to 1350 F (704 to 732 C), flux

19、 shall cause braze filler metal to flow with no evidence of balling or dewetting. SAE INTERNATIONAL AMS3410K Page 3 of 5 3.3 Quality Flux, as received by purchaser, shall be uniformly blended, free from contaminants and from foreign materials detrimental to the usage of the flux. 4. QUALITY ASSURANC

20、E PROVISIONS 4.1 Responsibility for Inspection The vendor of flux shall supply all samples for vendors tests and shall be responsible for performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the flux conform

21、s to the specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Tests for all technical requirements, except shelf life (3.2.6), are acceptance tests and shall be performed on each lot. 4.2.2 Periodic Tests Tests for shelf life (3.2.6) are periodic tests and shall be performed at

22、 a frequency selected by the vendor unless frequency of testing is specified by purchaser. 4.3 Sampling and Testing At least one randomly selected sample of flux shall be randomly selected from each lot. A lot shall be all flux in an identifiable quantity produced in a single run from the same batch

23、es of raw materials and presented for vendors inspection at one time. 4.4 Reports The vendor of flux shall furnish with each shipment a report stating that the flux conforms to all technical requirements. This report shall include the purchase order number, lot number, AMS3410K, date of manufacture,

24、 identification and quantity. 4.4.1 A material safety data sheet in accordance with FED-STD-313, or equivalent, shall be supplied to each purchaser, prior to, or concurrent with the first shipment of flux for production use. Each request for modification of flux formulation shall be accompanied by a

25、 revised data sheet for the proposed formulation. 4.5 Resampling and Retesting If any sample used in the above tests fails to meet the specified requirements, disposition of the flux may be based on the results of testing three additional samples for each original nonconforming sample. Failure of an

26、y retest sample to meet the specified requirements shall be cause for rejection of the flux represented. Results of all tests shall be reported. SAE INTERNATIONAL AMS3410K Page 4 of 5 5.
