Why the material of the soldering iron tips must be copper
The soldering iron tip (soldering iron tip) is mainly composed of five metal materials: copper, iron, nickel, chromium and tin.
The main body is copper, copper is preferably red (purple) copper, copper - as a heat conductor, is the main component of the soldering iron tip (soldering iron tip). Accounting for about 85% of the material of the soldering iron tip, copper has good thermal conductivity, which is conducive to the rapid heating of the soldering iron tip. Good soldering iron tips are made of copper. At present, some manufacturers use brass or even iron directly for profit. The cost is reduced, and the heat conduction effect of the soldering iron tip is also reduced.
