Como SOLDAR ALUMÍNIO e COBRE com Estanho: O Segredo da Gota Mágica! 🛠️

In this video, I'll share a valuable tip for those who enjoy recycling transformer wires and building their own electronics projects. Since copper wire is becoming increasingly expensive, many new transformers come with aluminum wires, and the big challenge is: how to solder aluminum with regular tin? I'll present the "Magic Drop" soldering flux from DNI. I'll demonstrate in practice how it allows for a perfect connection between aluminum and copper wires, guaranteeing total electrical contact and mechanical resistance. It's the ideal solution for those who want to save money without sacrificing quality. 🔗 Links mentioned in the video: Product technical information: https://dni.com.br/pt/hyb9999-fluxo-p...
