Product Description

3003 aluminum strip coil foil for Charge Air cooler

Of all the methods available for metal joining, brazing may be the most versatile. Brazed joints have great tensile strength - they are often stronger than the two metals being bonded together. Brazed joints repel gas and liquid, withstand vibration and shock and are unaffected by normal changes in temperature. Because the metals being joined are not themselves melted, they are not warped or otherwise distorted and retain their original metallurgical characteristics.

*Various kinds of specification for fin

*Excellent collapse resistance during brazing

*4343 can be replaced by 4045/4047/4104/4004etc, according to customer's requirement. *Alloy,specification and mechanical property can be customized according to different requirement.

3003 Aluminum is one of the most widely used of all aluminum alloys. It is a general purpose aluminum, with moderate strength, good workability and weldability, and excellent corrosion resistance. 3003 is a nonheat treatable grade, and it may be deep drawn, or spun, welded, or brazed.
 
*Excellent collapse resistance and strength after brazing 
 
*Good mechanical property and surface condition 
 
*Various specifications for soldering sheet
