Arnold Magnetic Technologies Member Spotlight

Arnold Magnetic Technologies, headquartered in Rochester, N.Y., is a global manufacturer of high performance magnets, precision magnetic assemblies and thin metals.  Arnold serves a variety of markets from consumer, industrial, and medical to military, aerospace, and telecommunications.  Its magnets, metals and systems are used in high-efficiency motors/generators, sensors, and batteries.

The Arnold Magnetic Technologies Precision Thin Metals (PTM) division, rebranded in 2014 from the former Rolled Products division, is dedicated to the development and manufacture of rolled thin and ultra-thin magnetic and non-magnetic specialty alloys, with continuous development of products to support emerging technologies. The Precision Thin Metals business is ISO 9001, AS9100 and Nadcap certified, and many of its alloys are DFARS compliant. The Precision Thin Metals business of Arnold Magnetic Technologies produces thin and ultra-thin alloys that improve the power density of motors, transformers, batteries and many other applications in automotive, aerospace, energy exploration, industrial and medical markets.   PTM's BESThin line of materials was launched at the end of 2014.  The product line includes nickel, aluminum and copper and enables thinner substrates to be used in battery and energy storage technologies.  They are available in thickness as low as 1/5 of industry standards.  As the push for new battery performance materials increases, titanium and stainless steel are also being considered. These thin substrates improve storage capacity by allowing for greater energy density in a smaller system.  PTM’s precision rolled thin and ultra-thin materials have applications in battery separators, cathodes, anodes, super capacitors, and fuel cells.

In addition to thin gauge, Arnold is able to improve material performance through fine-tuned grain size and grain structure and uniform surface roughness. These optimizations allow for precise deposition of electrode materials onto the substrate. Advances in battery technology hold particular promise for the automotive and transportation industries. Smaller, lighter, and more power dense designs will enable vehicles to meet stricter energy standards. Other applications that benefit from thin metal substrates include mobile devices, advanced fuel cells, and photovoltaic (PV) solar cells.

"Thin and ultra-thin metals play an important role in today's battery and supercapacitor technologies," said Ted Baker, General Manager of Arnold's Precision Thin Metals (PTM) division. "We're working with customers to overcome the challenges and limitations of each technology, in order to achieve more efficient electrification of their machines."

Arnold is an active member of NY-BEST and its nickel and aluminum materials for both lithium ion batteries and supercapacitors offer an important capability for New York’s industry supply chain.  The company is in the development stage with customers in this space and expects to be in production of these new products in 2016.
