Puralloy® Grade D 30/70 is a leaded solder alloy incorporating lead and tin, with a melting range of between 183-257°C. This leaded alloy is used in a variety of industrial soldering applications, from plumbing to vehicle restoration, particularly within the process of Lead Loading. Many Vehicle Restoration Engineers show preference for using Grade D for lead loading, over the more modern two pack Resin systems, due to its greater durability, malleable nature, and suitability for deeper filling. Grade D’s wide operating temperature further gives the engineer the possibility to wipe and form the solder joint before solidification. Incorporating a lower tin content than other leaded industrial alloys, Grade D offers a more cost-effective option for soldering. For soldering to brass or copper alloys, Bakers Soldering Fluid should be considered.
