In the intricate world of electronics manufacturing and repair, the integrity of every solder joint is paramount. The choice of solder wire directly influences the electrical conductivity, mechanical strength, and long-term reliability of your products. For professionals who demand proven performance and consistent results, the specific alloy composition is a critical decision. XF Solder, a leading manufacturer and exporter from China, is proud to present our flagship product: Electrical Grade Tin Lead Solder Wire Sn35 Pb65. This comprehensive guide delves into the features, benefits, and applications of this exceptional tin lead solder wire, specifically our popular solder wire Sn35 Pb65 35 65 variant packaged in a convenient tin lead solder wire 500g reel with a standard 1mm diameter.
Tin lead solder wire Sn35 Pb65 refers to a solder alloy composed of 35% Tin (Sn) and 65% Lead (Pb). This specific ratio, often denoted as tin lead solder wire 35 65, has been a cornerstone in the electronics industry for decades. Unlike higher tin-content alloys, the Sn35 Pb65 formulation offers a unique set of physical properties that make it exceptionally suitable for a wide range of electrical soldering tasks. It represents a classic, high-performance choice where the operational requirements align with its characteristics, providing a reliable and cost-effective solution for countless engineers and technicians worldwide.
The tin lead solder wire Sn35 Pb65 from XF Solder is engineered for excellence. Its primary characteristics include:
Optimal Melting Point: With a melting range of approximately 183°C to 247°C, it provides a sufficient working window for both manual and wave soldering processes.
Excellent Wettability: The alloy flows smoothly and efficiently over copper and other common surfaces, creating strong, concave fillets that are visually inspectable.
Superior Solderability: It ensures robust bonding, reducing the risk of cold joints or dry joints, which are common failure points in electronic assemblies.
Reliable Mechanical Strength: Solder joints created with tin lead solder wire 35 65 exhibit excellent shear and tensile strength, ensuring components remain securely fastened even under vibration or thermal cycling.

As a dedicated tin lead solder wire from China manufacturer, XF Solder controls the entire production process, from raw material sourcing to final packaging. We utilize high-purity virgin metals to create our solder wire Sn35 Pb65, ensuring a consistent alloy composition free from impurities that could cause oxidation or poor performance. Every batch undergoes rigorous quality control checks to guarantee it meets international standards, providing you with a product you can trust for your most critical applications.
A great solder alloy is only as good as its flux core. Our Electrical Grade Tin Lead Solder Wire is equipped with a meticulously formulated rosin-based flux. The flux is evenly distributed and cored within the wire, providing:
Effective De-oxidation: It quickly removes oxides from the metal surfaces to be joined, enabling perfect metallurgical bonding.
Enhanced Flow: The flux reduces the surface tension of the molten solder, allowing it to wick into tight spaces and create perfect joints.
Minimal Residue: Our flux is designed to leave a relatively clean, non-corrosive, and non-conductive residue that typically does not require cleaning, streamlining your production process.
We understand the needs of both large-scale production floors and busy repair workshops. That's why we offer our high-quality tin lead solder wire for sale in a practical and economical tin lead solder wire 500g reel. This size is ideal for continuous use without being too bulky, making it a perfect inventory item that reduces the frequency of changeovers and maintains a steady workflow. The robust reel packaging also protects the wire from tangling and damage during storage and transport.
