20/50/100g Low Temperature Easy Melt Solder Wire Stainless Steel Metal Weld Cored Aluminum Copper Iron Welding Soldering Rod Welding Tool

Material: tin lead alloy+plastic. Category: Solder wire. Size: The diameter of 20g model is about 4.5cm, The diameter of the 50g model and the 100g model is about 5.5cm. Package includes: 1 roll of solder wire. Description: 1. High purity raw materials: Our soldering wire is made of high-quality and high-purity soldering raw materials, adding 2.2 special flux to ordinary tin alloy. During the welding process, high-purity materials help slow down oxidation, thereby accelerating the tin flow rate and minimizing residual impurities2. Durable and sturdy: Ensure sufficient quantity of solder wire per roll. The tin wire will not tangle, and the rosin inside the tin wire is evenly distributed, ensuring good continuity. When you use our soldering wire, you will find it sturdy and durable. It has good extensibility, melting, conductivity, and thermal conductivity. 3. Green and fresh odor: Made of environmentally friendly materials, without irritating odor, fresh and natural. Designed specifical
