Product Description

4343/3003/7072 Aluminum strip coil for tubes

Brazing is the process of uniting two or more metals of similar or dissimilar type with the help of an alloy in the form of spelter and flux, like borax, ash etc. these are used in tanks, radiators, carbide tips on tool holder etc

The most common filler metals used in brazing include:
• Aluminum-silicon
• Copper
• Copper-phosphorus
• Magnesium
• Silver
• Nickel alloys


*Various specifications for B-TUBES,ratio-frequency welded tubes and other tubes

*Good surface condition and slitting precision

*Excellent collapse resistance during brazing

*Perfect corrosion resistance and long life
