Project Description
COPPER BRAZING ALLOY
These copper brazing alloys have excellent corrosion resistance and high eletrical and thermal copper conductivity. One of the most widely-used alloy is the Copper-Phosphorous alloy,
which have outstanding brazing properties and wide capabilities. Phosporous acts as a reducing agent for copper and also deoxidizes silver.
Available Shapes : Wire, Rod, Flat, Square, Spool, Ring, Paste/Powder
