Features
Flast A
33.4
Necessary
Applicable to materials difficult to solder. With broad soldering temperature range of 130 to 450℃. The spreading rate is 95% for cupper, 95% for brass,90% for nickel,88% for stainless steel, and 90% for steel.
Flast S
0.0
Necessary
Especially for stainless steel,but applicable to copper,nickel and steel as well. Capable of soldering at relatively low temperature(about 250℃). Dissolves above 350℃,making soldering impossible. Umit soldering temperature to below 300℃. The spreading rate is 92% for copper,92% for brass,90% for nickel,90% for stainless steel, and 91% for steel.
Flast D
0.36
Unnecessary
For terminating copper wire;non-corrosive. To terminate wires,apply flux,then dip the wires in a 350~450℃ solder bath. The spreading rate is 92% for copper
