Where We Come From
Kapp Alloy & Wire was founded by Mr. Donald Black in 1945, beginning with his very first invention — Alumite™ — a powerful solder still used today for cast alloy repairs. Through the 1960s and 1970s, our solder was a component of virtually every microwave and telephone manufactured in the United States. Our legacy of precision even extends beyond this world — Kapp Alloy solder traveled to the moon and back, used in instrumentation aboard the historic US Apollo missions.
For nearly eight decades, that same spirit of innovation and excellence has driven everything we do.
