Kapp Alloy & Wire was founded by Mr. Donald Black in 1945, to sell his first invention - ALUMITE™ - an extremely strong & easy to use solder for Aluminum and white metals. Alumite™ is still used today around the world for casted alloy repairs. Since its humble beginning in Don's garage, Kapp Alloy has focused on product quality and innovation. Throughout our history, our solder has been found in the latest technology. Kapp Alloy solder was part of every telephone Western Electric and AT&T made, and was part of every microwave made in the USA. Kapp solder even went to the moon and back in instrumentation aboard the US Apollo missions!
