Tin-Lead Plating
Tin-Lead – 60/40 & 90/10 Alloy composition
Alloys of tin and lead, containing between 10 and 40 percent tin by weight, are used in electroplating to protect the base metal from oxidation and to enhance its solderability. The main advantage of these tin-lead alloy compositions is their ability to retain solderability while reducing the likelihood of spontaneous metallic whiskers, which is vital for safety and mission-critical applications.
Benefits of Tin-Lead Plating
 | Tin-lead alloys have a low melting point, facilitating their use in various applications. |
| Tin- lead can be soldered easily by a wide variety of methods. |
| They exhibit a notable resistance to corrosion, enhancing their durability. |
| The alloys possess excellent electrical conductivity, making them suitable for electronic applications. |
| Their ductility allows for further processing, such as stamping, without compromising their integrity. |
