Over the past quarter century, Nuclead Co. Inc. and Sharp Manufacturing have partnered to provide lead and shielding solutions for research and industry. As full service, ISO-9001:2000 certified manufacturers and fabricators, we carry a diverse product line – from basic sheet lead products and lead castings to sophisticated CNC machined items and assemblies constructed of lead and other metals.
Nuclead Co. Inc.

Established near Boston at the turn of the 20th century as the Cambridge Smelting Company, this family business provided quality lead products for the housing and plumbing industry for decades. As industry changed, and the demand for lead products diversified and became more sophisticated, so did the company. In 1981 the Nuclead Company incorporated, later partnering with Sharp Manufacturing to extend its product line into high technology markets. The integration of the two companies has allowed us to become an unparalleled source of lead and metal machined value-added products.

To handle business demand, a modern, climate controlled Nuclead warehouse was built in West Bridgewater, MA, while lead manufacturing continues at the original Cambridge plant
