Sn Cu0.7 without Tin is Copper-based binary alloy of tin lead-free solder,This section of the solder has been applied for many years in the industry, the performance has been achieved recognition. Our high purity raw materials and refined through the use of technology and the introduction of high antioxidant elements, better wetting and brazing strength in welding and slag less. Widely used in wave soldering, hot dip soldering electronic products welding process. The products are divided into high-temperature oxidation, low temperature anti-oxidation two products for customers to choose.
