Lead-free welding wire with different specification available. Sn-Ag3.0-Cu0.5 Sn-Ag0.3-Cu0.7 Sn-Ag3.5-Cu0.5
TC lead-free welding 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-Cu0.7 | |||||
