Like many other solder materials, the low-mid temperature alloy solder is used for soldering aluminum metal and alloys, and to some lesser extent steel and zinc. It is a lead free solder whose principal element is SN. Its mechanical soldering is similar to a low temperature brazing operation, in that the mechanical characteristics of the joint are reasonably good. Besides, this alloy solder can be used for structural repairs of those materials.
1. Low-mid temperature alloy solder has good brazing effect and great fluidity.
2. The mechanical performance is perfect.
3. After welding, this lead free solder has high reliability and fine thermal fatigue property.
4. The low-mid temperature alloy solder can be compatible with all copper-based radiator solder alloys and lead solders.
5. With this solder, repairs are stronger than original joint and have a higher melting point than original joint. It is excellent for radiator repair.
Low-mid temperature alloy solder has two subclasses as follows.
(1) Sn91Zn9 Alloy Solder Bar (Tin Zinc Alloy Solder Bar)
(2) Sn89ZnBi3 Solder Bar (Tin Zinc Bismuth Alloy Solder Bar)
Different alloys have different solidus and liquidus melting points. Please refer to the following pictures.

Using a vacuum induction furnace. Good brazing process for transition joints for brazing copper and aluminum, stable mechanical properties of brazed joints, good electrical properties, used in electronics, electrical appliances, such as televisions, radios, radio transponders, instruments and calculators, etc.
And lead, three low-temperature solder alloy of tin, there AgPbSn36-60, AgPbSn70-27 and AgPbSn97-1.5 and other brands. Good Brazability than ordinary tin solder has good corrosion resistance and heat resistance. Smelting and manufacturing pressure processing method. Used for welding copper and copper alloy parts, there is a good impact toughness and corrosion resistance, strength of welded joints.
TV sets, computers, radios, and so on. Factors, such as melting point, plastic range, wetting speed, wetting ability, soldering methods, etc.Factors, such as melting point, plastic range, wetting speed, wetting ability, soldering methods, etc. must be considered when electing the proper lead-free solder alloy.
This heat gun is widely used in advertising cloth, tarpaulin, water-proof film, impermeable liner, water-proof membrane, pipe, electronic components, car bumper, sports floor, electroplating tank, plastic pipe, PP/PE/PVC and other sheet. The hot air gun is also suitable for membrane structure welding, geomembrane local welding and repair.
A low temperature solder of bismuth, indium, cadmium in the formation of solder in the solder alloy, mainly for microelectronic sensor assembly of parts with low heat resistance, good wettability and solderability, solder full, uniform welding excellent results, without requiring high temperatures and pressures may be used to seal solder metal welding.
