Product Description

4343/3003/4045 aluminum sheet plate for Evaporator fin 

Although brazing, soldering and welding are similar in many respects, there are important differences. Soldering generally can be done at lower temperatures (below 450°C), but does not produce as strong a joint. Welding, a higher-temperature process in which the two metals to be joined are actually melted and fused together, requires the most heat energy. Welded and brazed joints are usually at least as strong as the metals being joined. The welding process is ideal for applications which benefit from highly localized, pinpoint heating. But it is more difficult to apply to linear joining, not as easy to automate, and not easily adaptable for joining metals with different melting points.

*Perfect property for fine stamping 
 
*Good consistency for any fin mill 
 
*Excellent collapse resistance and strength after brazing
