The Precision Thin Metals (PTM) division 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.
For example, our Silicon Steels improve the power density of motors and transformers, our ultra-thin Ni, Al and Cu are facilitating the development of tomorrow’s batteries, while our thin Titanium strip is both strengthening and lightening components used in the aerospace industry.
Thinness is a relative term and we’re often asked how we categorize the end-product’s thinness or gauge. We define thin and ultra-thin this way:
0.060″ to 0.0005″
1.524mm to 0.013mm
Ultra-Thin / Foil
0.00049″ to 0.000069″
0.01245mm to 0.00175mm
