This solder alloy from ASAHI
SCS7 is a lead-free tin-copper (Sn-Cu) solder alloy supplied by ASAHI, developed as a direct replacement for SnCu0.7 in high-temperature wave soldering. The description below is based on the manufacturer's official information.
Product Description
SCS7 has a documented melting point of 227°C and is specified as an improved tin-copper alloy with increased mechanical strength and ductility compared to previous SnCu variants. The manufacturer states low drossing and good wetting properties as characteristics of the material. SCS7 is offered in both bar and solid wire form and in several core wire diameters.
Documentation
Further technical information and product information are described by the manufacturer: Manufacturer's product page.
Typical Applications
- Recommended as a direct replacement for SnCu0.7 in high-temperature wave soldering.
- Used for wave soldering and dipping processes, according to the manufacturer's information.
- Can be used for manual and automated soldering, as well as for touch-up of solder joints with solder wire.
Material Properties
Information from ASAHI indicates that SCS7 has improved mechanical strength at both ambient and higher temperatures, and that its fatigue resistance approaches that of tin-lead alloy. For core flux, ASAHI recommends CLF5023, classified as ROL0 and specified as halogen-free, as compatible with SCS7 and SnCu0.7.
