Cord Master Engineering provides lead tinning services. By applying tin to some materials the solderability can be improved so that soldering is possible. Tin plating then becomes a step in the hot solder dipping process.
“Some materials are easier to solder than others. Copper, silver, and gold are easy to solder. Iron and Nickel are a little more difficult. Titanium, magnesium, cast irons, steels, ceramics, and graphites are hard to solder. However, if they are first plated they are more easily soldered. An example of this is tin-plating, in which a steel is sheet coated with tin so that it can be soldered more easily.”
