Sn Cu Lead Free Solder Bar

Force a tin tin lead solder wire is made ​​from pure and high purity tin ingot 1 # lead ingots. Application of stable performance, low melting point, good fluidity, shrinkage is small. Fine grain, good toughness, suitable for hard and soft, smooth surface, no sand holes, no defects, no cracks, good polishing and plating effect. Suitable for decoration, high plasticity.

This tin silver copper alloy solder wire/bar/rod (Sn99Ag0.3Cu0.7) is also known as SAC0307 lead-free solder. It is applicable for precise LED, mobile phone chips, PCBs, etc. in many hi-tech wave soldering machines and small-sized tin furnaces.

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.

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

As a filler metal wire or both as a conductive wire welding materials used. When gas welding and gas tungsten arc welding, welding filler metals used; in submerged arc welding, electroslag welding and other time MIG arc welding, welding filler metals both, but also conductive electrodes. Surface oxidation coated wire is no.
