🔥 HIGH PURITY RAW MATERIAL
Our lighter solder wire is made with 2.2% special flux added based on common tin alloy. Its outer ring alloy composition is tin-lead, special lead-free flux is evenly infused into the middle part of the tin alloy, and there is no flux breakage in the tin core. During soldering, the high purity material helps to slow down oxidation, resulting in faster tin flow and minimal residual impurities.
