component but also technology for producing newly sintered
products such as for motor companies requiring specific
magnet shapes and performances, designed and engineered to meet their specs including machining and coating." Magnetic performance of the company's products can
be tailored according to customer goals and requirements.
"For a couple years, we have been prototyping our output
for a customer base in automotive, aerospace, defense and
control automation," reports Dunn. "We have also been prototyping bonded magnets with electric motors particularly as
a target application." Currently, these operations have been
taking place at the company's development site
in Austin where they conduct manufacturing,
quality control and research of their materials
and products.

"Most important now are the risks entailed in
scaling up at the new facility and selecting the
right customers, particularly motor manufacturers, as we allocate our finite initial production
capacity," replied Dunn when asked about the
steps ahead most critical to the company's success.
Two technical papers published recently report
on some of Urban Mining's work to date. According to Zakotnik, CTO, and Davide Prosperi, chief
quality engineer, the work establishes some
important findings about the company's recycled
magnets.
Among the key findings in one report are that
use of its recycled NdFeB magnets in a motor
has shown the capability to perform as well as
virgin magnets; that its recycled magnets have
temperature coefficients for Br (flux density,
residual induction) and Hcj (resistance to demagnetization) respectively 24% lower and 16%
higher than virgin magnets; and that measured
values of flux linkage and torque are around
7% higher for a motor equipped with recycled
magnets.

Laboratorio Elettrofisico is a global company
specializing in engineering, design and manufacturing
of magnetizing and magnetic measuring equipment.

In another study, key findings they cite include
that their M2M and GBE magnets offer a green
and technically viable production option, that
the recycled magnet exhibits similar or better
temperature stability to conventional magnets,
and that oxygen and carbon contamination are
similar in recycled and conventional magnets.
Along its way, Urban Mining has been increasingly recognized for its efforts toward both
recycling and creating a domestic supply of
rare-earth magnets. In August, it was named
by Fortune Magazine to its "2019 Change the
World List: Companies to Watch".
