China Supplier Fa-225/Fa-240 Surfactant for Aluminum

1.Product Description
Aluminum flux is a white powdery mixture of potassium krypton aluminate (non-corrosive and non-hygroscopic). This fiber agent is a high-quality and high-purity product, which has passed an extremely strict production process and quality control process.
The melting point of the aluminum fiber agent ranges from 550 to 574, which is the melting point of the low-kilo aluminum-silicon fiber welding alloy. The particle size distribution ranges from 0.1 μm to 50 μm, and the particle size distribution range of this product is different according to the difference of the use process. At present, there are mainly two methods of using the process, one is the spraying or brushing and soaking process dispersed with water, and the other is the process of using electrostatic spraying dry powder. In the process of aluminum fiber welding, the aluminum injection can dissolve the oxides on the surface of the aluminum material (mainly remove the AL203 on the surface of the aluminum material), and make the solder layer on the metal surface flow capillary and flow freely into the welding place. The residue after cooling is a thin film The form is attached to the surface and is non-corrosive and non-hygroscopic, and the welding area does not need to be cleaned after brazing.
