ONE: Operation Introduction  The
tin-lead filler metals are mainly made up of tin and lead two elements
with a little other element .They have low melting point and resistivity
, good corrosion-resisting , good wettability to copper , copper alloy
, steel and stainless steel . The tin-lead filler metals whose tin
content are over 50% are mainly used in electric , electronics industry
and tableware etc . The tin-lead filler metals whose tin content are
less than 40% are mainly used in light bulb , heat-converter , automobile
water box and lead tube .The kind of solder needs to use a flux .The cadmium-base filler metals' melting temperature is between 250¡æ to 360¡æ . The working temperature with the joint can reach over 200¡æ . They are usually used to solder copper ,copper alloy , steel and aluminum etc. In the process of solderng , a suitable flux must be used together . The vapor of cadmium is poisonous , so the working place must wind . |
