Silver solder

Silver solder products such as solder wire/solder bar. RoHs complaint solder products. Different specifications accepted.

  

TC lead-free solder wires:

Spec	Melting point	Tensile strength	Extensibility	Rate of spread	Usage
Sn99.95	232	20	43	70	Electroplating anode bar
Sn-Cu0.7	227	30	45	70	Lower cost, high melting point, poor wetting, low caplillarity, poor fatigue property, can be used for low requirements soldering.
Sn-Ag3.5	222	38	54	75	Higher cost,
Sn-Ag3.0-Cu0.5	217	40	58	78	Higer cost, good performance, first choice by most of factories.
Sn-Ag0.3-Cu0.5
Sn-Ag3.5-Cu0.7

Recommendation: Sn-Cu0.7, Sn-Ag3.0-Cu0.5, Sn-Ag0.3-Cu0.5

Types of Lead-free solder bars:

Common lead-free solder bar:

The most common solder bar in the lead-free solder bar series, and it will take the place of welding accessories in daily use. With stable quality and property, good solder ability and low cost.

Wave-soldering lead-free solder bar:

It was developed for wave-soldering. Added with agel exo element in the recipe, high brightness, minimum oxide residue. It is better to add Nitrogen while using wave solder pot, so as to reduce the waste from air oxidation.

High temperiture lead-free solder bars:

It is suitable for high temperature soldering place, temperature up to 400-550. The recipe is with special metallic elements which are with powerful high temperature and oxidation capacity, so the cost is much higher.
