HOW WE BONDPROCESS & CAPABILITIES

Polymet clads long coils of dissimilar metals together using roll bonding with extreme pressure and heat as needed to optimize bond strength and integrity.

To assure the best possible bond, our hot bond process is performed in a controlled atmosphere that prevents oxidation or the introduction of impurities at the bond interface. Cold bonding is utilized for materials best clad without heat.

Finished thicknesses from 0.004” to 0.218”. Widths up to 3.7”. Longest coils in the market.
