Sn95.5Ag3.8Cu0.7 Solder

The biggest advantage is its copper solder easily reduced oxides of copper, nickel and other metals have good wettability, in vacuum or protective atmosphere brazing carbon steel, low alloy steel, stainless steel, nickel, copper-nickel alloy , tungsten and molybdenum. In a reducing atmosphere brazing, the brazing material should be used, or oxygen-free copper deoxidized copper brazing.

It is mainly filled into the weld line, cladding layer or brazing seam. Generally, the aluminum solder includes welding wire, rod and welding ring.

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.

When using solder as arc welding, the temperature often exceeds the base metal and solder itself many, no hard and soft points; while solder hard solder, such as copper and zinc materials (copper-zinc alloy), silver solder (silver-copper alloy ) of the solder joint strength was largely higher connection strength requirements for metal member, and a smaller solder as solder (tin-lead-based alloy) welded joint strength, but is mainly used to connect the required strength of small joints, such as electronic equipment, instrumen
