CUSTOMER SERVICE

Our original mission was to provide our customers with specialty clad metal products made to the highest level of bond integrity in the industry. That legacy survives today with our emphasis on total customer satisfaction. From simple overlays to complex multi-gauge clads, parts or assemblies our Customer Service Team is prepared to work with you to develop a clad metal system that satisfies your specific need.

QUALITY ASSURANCE

NN’s Quality Management System is registered to ISO 9001:2000. We are certified suppliers to many leading companies around the world. Continuous improvement is one of our core principals, requiring us to involve our entire Team at all levels of the process and to provide them with the training and tools they need to achieve their maximum potential. Unique process specifications are rigorously maintained for every item we manufacture assuring lot to lot consistency and traceability.

ENGINEERING

Controlled Atmosphere Bonding is the key to NN’s success. This unique capability, developed and refined in-house, provides a clad product that is ideally suited to the needs of high-reliability applications. Whether your requirements call for consistent thermal performance from part to part and year-to-year or exceptional electrical performance in either arcing applications or light duty connector usage, our CA Bonded clad metal products will do the job to your complete satisfaction.

COMMITMENT

Our technology and extensive cladding experience are your assurance of our commitment to reliability. That commitment translates into consistent product quality, on-time delivery performance, competitive pricing and our entire Team’s determination to earn your confidence with each and every order.

CONTROLLED ATMOSPHERE (CA) BONDING PROCESS

NN’s clad metal technology combines the desirable characteristics of two or more materials into one. The result is a composite material system with an intermetallic bond that is configured to meet your exact specifications and quality requirements. Benefits of using clad metals include improved product performance, reduced material costs, simplified production processes, and reliable metal consistency.

To assure the best possible bond, the process is performed in a controlled atmosphere that prevents oxidation or the introduction of impurities at the bond interface. The result is a clad metal system with thicknesses ranging from 0.002” to 0.250” and widths up to 4.00”, with individual components as thin as 0.000025”.

NN uses both conventional and proprietary bonding techniques to produce metals of superior bond integrity and quality. Our multiple state-of-the-art bonding lines are designed to provide our customers with long continuous coils of material that consistently meet and exceed end user production requirements. Time and time again.

PRODUCT

NN produces standard thermostat metal and custom clad metal products in the broadest range of combinations, configurations, and dimensions in the industry. Virtually any ductile material can be bonded to produce a material system with the exact characteristics that your application requires. By precisely selecting materials, we produce composites that effectively enhance strength, conductivity, appearance, heat dissipation, expansion coefficients and anti-welding ability, while reducing product and process costs.

NN’s clad metal products give design engineers complete freedom to create the specific characteristics they need, rather than adapt their designs to an inferior mono-metal. Our engineers are always available to discuss your desired clad metal applications.

Consistently high material quality is assured through a series of state-of-the-art technical quality control processes. But, more importantly, it is assured by a management and employee commitment to the highest standards of clad metal excellence.

THERMOSTAT METALS

NN manufactures all of the ASTM standard thermostat metals as
well as special types specifically engineered to customer’s requirements. If one of our 62 types of thermostat metals is not suitable for your application, our engineering team can tailor a custom thermostat metal system specifically for your application.

NN’s proprietary Controlled Atmosphere bonding process is capable of producing the thickest thermostat metals available worldwide and assures you the best bond and largest coils of consistent quality. Complete test facilities monitor key parameters such as flexivity, resistivity and hardness. NN’s thermostat metals are available in thicknesses ranging from 0.004” to 0.150”.
