TECHNICAL REQUIREMENTS 3.1 Material The flux shall be a uniformly blende

13、d mixture, primarily metallic chlorides with the addition of metallic fluorides. Other metallic salts of alkaline metals are permitted as required to assist in fluxing ability. 3.1.1 The flux, used in accordance with AMS2673, shall produce satisfactory brazed joints acceptable to purchaser. 3.2 Prop

14、erties Flux shall conform to the following requirements: 3.2.1 Flux shall be fully molten at 1030 F (554 C). The liquidus of the flux shall be 1030 F (554 C) or lower. 3.2.2 Flux shall not etch parent metal to an extent greater than indicated by the following test: 3.2.2.1 A coupon of aluminum alloy

15、 1100 or 3003, nominally 0.025 u 1 u 6 inches (0.64 u 25 u 152 mm), immersed for two minutes 0.2 minutes in a bath of dehydrated molten flux at 1120 F 10 F (604 C 6 C), shall not be reduced more than 0.001 inch (0.025 mm) in thickness. 3.2.3 Flux adhering to brazed assemblies shall be removable by e

16、ither: 1) water at 190 F (88 C) or hotter or 2) by the hot water followed by immersion for not more than 15 minutes in a 10% (approximately) solution of nitric acid to which 0.25% (approximately) hydrofluoric acid is added, at a solution temperature not higher than 100 F (38 C). 3.2.4 The flux shall

17、 not contain more than 5% by weight water as determined by the water content test in accordance with AWS A5.31. 3.2.5 Flux shall pass the fluidity test in accordance with AWS A5.31. 3.2.6 Flux shall pass the flow test in accordance with AWS A5.31.
