Product Description

4343/3003/4343 aluminum strip coil foil for Parallel Condenser fin

The most common filler metals used in brazing include:
• Aluminum-silicon
• Copper
• Copper-phosphorus
• Magnesium
• Silver
• Nickel alloys
Each of these flow at specific temperatures and are available as wire, foil, paste, powders, and preforms. Filler metals typically have chalcoficantly different compositions from the materials being joined, for this reason their selection is critical to successful brazing.

*Various kinds of specification for fin

*Excellent collapse resistance during brazing
