When buying solder wire (tin) for your projects, you've probably come across spools of different colors. Is it just for looks? Does it have a meaning? And which one should I choose? I hope to answer these and other questions in this video. And if you need to buy solder wire, or any equipment for your bench, whether for soldering, measuring or projects, don't forget: RAISA. Store: https://www.raisa.com.br Solder Wire (tin): https://www.raisa.com.br/soldagem-ele... Tin (Sn): This is the main component in most solder mixtures. It is used for its electrical conductivity and corrosion resistance properties. Lead (Pb): Lead is added to reduce the melting point of the solder and improve its fluidity. However, due to environmental concerns, many types of solder are now “lead-free”. Flux: Flux is a substance that promotes the cleaning of the metals to be soldered and the formation of a good solder joint. It is classified according to its activity (or aggressiveness) and can be resinous, organic, or inorganic. Flux can be added to the core of the solder wire or applied separately. Explaining how mixtures influence the properties of tin The proportion of these elements in the solder tin mixture can significantly affect its properties and performance. For example, a high tin content will result in a solder with greater corrosion resistance but a higher melting point. A higher proportion of lead will reduce the melting point, while the addition of silver can improve thermal conductivity. Ultimately, the ideal solder tin mixture will depend on your specific soldering needs, including the nature of the components to be soldered, the type of application (e.g. consumer electronics vs. military), and the environmental conditions in which the soldering will be performed. Understanding these factors and knowing how to select the right mixture is an essential part of the soldering process. Raisa is here to help you find the best option for your needs, offering a wide range of solder tins from market-leading brands Best and Cobix. The 63x37 is an aesthetic alloy, that is, it changes from solid to liquid state without undergoing physical changes.
