Aluminum brazing flux

Aluminum brazing flux is a fluoride brazing flux ,which is without corrsion,better activity under higher temperature and low residue after soldering.It's easy to clean,and widely used in the trade of diators and dishware. The main performance: 1. Brazing temperature:590-620 degree. 2. No corrosion and not absorbing humidity. 3. Low residue and easy to clean. The main physical and chemistry performance: 1. Melting Point: 556+/-5 degree. 2. Apperance: white powder. 3. Main Chemical position: K: 30.6%-31.0% Al: 17.2-17.7% F: 51.3%-52.3% Others: 0.5%-1.0% The main purpose: 1. Used in the trade of aerospace, auto,train,chemical,electronic and dishware. 2. The brazing of aliminum evaporator,radiator,condensator and condenser. 3.The brazing of bottom of stainless boilder under the heating of high frequency
