VACUUMSCHMELZE GMBH & CO. KG
ADVANCED MATERIALS – THE KEY
TO PROGRESS
VACUUMSCHMELZE is a global company
with more than 4000 employees and
production locations as well as sales of-
fices in more than 40 countries. As one
of the leading companies VACUUM-
SCHMELZE develops, produces and mar-
kets magnetic materials and products
derived of them.
HIGH PERFORMANCE MATERIALS
All our materials are manufactured in our
own vacuum furnaces or rapid solidifica-
tion casting equipments.
•
Soft magnetic NiFe or CoFe materials
•
Amorphous and nano-crystalline
rapidly solidified alloys
•
Magnetic, semi-hard formable materials
•
Alloys with special physical character-
istics
•
Brazing alloy foils of rapidly solidified
materials
These materials are the basis for a wide
variety of products. We supply alloys in
the form of tapes, strips, round rods or
wires. Many are also available as lamina-
tion packages, stamped and bent parts
as well as magnetic shieldings.
TAPE WOUND CORES AND CUT CORES
Highest permeabilities and flux densities
as well as minimal losses of our materi-
als allow the design of advanced magnet-
ic cores. Many of these are based on the
latest generation of soft magnetic materi-
als, the nanocrystalline alloy VITROPERM
®
INDUCTIVE COMPONENTS
Our knowledge of cost effective design
and quality manufacturing, our own ma-
terial base and our experience with inter-
national markets lead to innovative com-
ponents of extreme reliability.
•
Current sensors with a minimal offset
and the lowest possible temperature
drift, e.g. for variable frequency drives
or for photovoltaic inverters
•
Compact power transformers with
high efficiency in the several 10th of
kilowatt range based on our nano-
crystalline cores, e.g. for welding, trac-
tion or renewable energy applications
•
Reliable and safe trigger transformers
for power semiconductors
•
EMC components with nano-crystalline
cores are smaller and more efficient
•
Precision current transformers with
amorphous and nano-crystalline cores
for long-term stable electronic energy
metering
•
Differential current transformers for
highly sensitive residual current circuit
breakers.
RARE-EARTH PERMANENT MAGNETS
As a leading supplier of permanent mag-
nets we use our experience in applica-
tion and development to offer the best in
product quality.
•
Specific process engineering combined
with alloy competence
•
Reliable performance at the highest
standards also in mass production
quantities
•
Processes for optimised corrosion
resistance developed by VAC
•
VACODYM
®
Nd-Fe-B rare earth
magnets rank among the most power-
ful magnets in the world. Nowadays
electrical heavy-duty machines are
operated with VAC magnets far into
the MW power range; for instance
as propulsion systems in ships or as
generators in wind turbines.
Besides permanent magnets we also
manufacture complete magnet systems
of every required size and complexity
for a wide variety of applications.
