Lucas-Milhaupt, Inc. was founded in 1942 as a tool manufacturer, but soon turned to the production of silver alloy brazing preforms for the joining of metals. The use of preforms was a new technology that accelerated greatly due to the demand of World War II. In 1967, Lucas-Milhaupt was acquired by Handy & Harman, a widely diversified industrial manufacturer with a rich history of product and process innovation.
Handy & Harman began in 1867 as a trader of precious metals but soon became precious metal fabricators, refiners and processors. The development of a major new product line, brazing filler metals and fluxes for joining metals, enabled the growth path toward industry leadership in brazing technology. As early as 1905, Handy & Harman began supplying customers with small quantities of customized “silver solders” used to join or repair silver articles. These solders gradually found application beyond the arts industry and were increasingly used by general industry to join all types of metals with strong, leak-tight bonds. These materials became known as Easy-Flo®, Sil-Fos® and Handy Flux® and have been synonymous with brazing excellence for over 75 years.
Over the years, Handy & Harman technicians continued to develop several groundbreaking new product families including: the Braze™ family of alloys for cadmium-free metal joining, Trimet®, a tri-metal clad metal strip for joining mining and cutting tools, and Premabraze®, high purity vacuum tube grade filler metals for electrical/electronic applications.
