Product Introduction
Our lead solder wire alloy is composed of Sn25%Pb75% and is made of high purity electrolytic Yunnan tin metal raw material. This alloy has the following characteristics:
01 Fast diffusion speed: The lead solder wire alloy has a fast diffusion speed during the welding process, which can quickly melt and mix with the welding material to form a uniform weld. This helps to improve welding efficiency and welding quality.
02 Good continuous weldability: Lead solder wire alloy has good continuous weldability and can maintain stable welding performance in the continuous welding process. Whether in the automatic soldering machine welding or manual welding process, it can provide stable welding results.

Our lead solder wire products undergo strict quality control to ensure accurate and stable alloy composition. It has good welding performance and can provide high quality welding results. Whether in the automated production line or manual operation, we can meet the needs of customers.
We are committed to providing customers with high-quality lead solder wire products, as well as perfect pre-sales consultation and after-sales service. We will continue to improve and innovate, and work with customers to develop together.
The company manufactures lead solder wire items by utilizing pure tin metal sourced from Yunnan, China. The production process involves stringent quality control measures, vacuum deoxygenation treatment, and the use of advanced automated equipment for extrusion production. These methods effectively manage the level of oxidation and the presence of impurities in both metallic and non-metallic forms.

Service Capability


Hey, let’s talk about high-temp solder wire—you know, the stuff that doesn’t melt when things get hot? Regular solder wires melt too easy, right? Like that common 8812 one, it only handles 250-280°C. But when you’re packaging chips, you gotta bake ’em multiple times at high temps. Conventional lead-
During wave soldering, dip soldering, and other soldering processes, excessive dross on the solder pot surface not only increases solder bar consumption costs but also leads to solder joint inclusions, cold joints, poor soldering quality, and even reduced overall production line efficiency.
