Puralloy® Grade F 50/50 is a leaded solder alloy incorporating lead and tin, with a melting range of between 183-212°C. This leaded alloy is used in a variety of industrial soldering applications including general engineering work on copper, brass & zinc. This alloy can also be used within Stained Glass Manufacture for both leaded and copper foiled applications. Incorporating a lower tin content than other leaded industrial alloys, Grade F offers a more cost-effective option for soldering. Garde F solder has similar physical properties as the other leaded alloys, including a pasty range which allows for movement and re-alignment before returning to solid. Grade F has a duller finish, which can sometimes be an advantage when again compared to higher tin materials.
