Machining 4047 Aluminum Coil Strip
4047 aluminum coil strip has good wettability, fluidity, corrosion resistance and workability, and is the most widely used aluminum-based solder. AA4047 is a eutectic solder. Its fluidity is too strong and difficult to control at the recommended brazing temperature. It has a higher dissolution tendency than other solders. It is generally used for flame brazing.
