ALPHA® Solder Preform Sleeves

Solder sleeves are the work house solder material for all aerospace, marine, military and some automotive wire harness applications.  Alpha is the world leader in solder sleeve production, and the industry’s innovation giant.  Alpha offers a wide variety of standard solder sleeve alloys, and sizes.

Alpha also offers a number of value added features for solder sleeves to ensure the highest assembly integrity possible.  Alpha’s thermal indicator materials can be added to the flux coating of solder sleeves, providing a color change at a temperature above the melt point of the solder.  This ensures that an adequate temperature is achieved, ensuring a robust solder connection.

Alpha also offers dual alloy solder sleeve solutions.  Dual alloy solder sleeves consist of a solder sleeve of a base alloy, and a thin outer band, which is build with an alloy of a higher melting temperature.  Once sufficient heat and temperature is applied to melt the outer band, this ensures that the base alloy has received adequate temperature to guarantee a robust solder connection.
