Where We Come From

Kapp Alloy & Wire was founded by Mr. Donald Black in 1945, to sell his first invention - Alumite™ - a strong solder still used today for casted alloy repairs. During the 1960s and 1970s, our solder was part of every microwave and telephone made in the USA. Kapp Alloy solder even went to the moon and back in instrumentation aboard the US Apollo missions!
