SOLUTION PROVIDER MEDICAL ALLOYS
For decades now, the companies of the Zapp Group have
been supplying semi-finished metal products made of
stainless steel, titanium and titanium alloys, nickel and
cobalt-based alloys, as well as a large number of special
materials. Building on this experience with a view to
becoming a specialist in medical technology needs, the
alignment of MEDICAL ALLOYS’ organization is unique
to the steel industry: it concentrates exclusively on your
metal semi-finished product requirements. Our staff
provides you with expert support to help you select the
ideal material for your specific application. Across the
complete spectrum of product forms – from wires, bars,
profiles, strips and sheets to tubes – we offer a compre-
hensive, continuously expanding range of material
solutions comprising our own products as well as trade
activities.
YOUR PURCHASING DEPARTMENT BENEFITS
Along with our extremely broad product portfolio we are
able to offer you the technical service and development
capabilities of an established manufacturer, saving you the
time and expense of a long search for the right partner.
Joint developments to address special requirements are
part of our everyday business. Take advantage of our
expertise:
_ Comprehensive application engineering support from
the initial idea right through to serial production
_ Special material variants created by combining material-
specific product characteristics and sophisticated pro-
cess engineering to induce particular mechanical/tech-
nological properties
_ A sales team trained in commercial technology to sup-
port your product selection process

LOGISTICS
The comprehensive distribution and logistics network of
the entire Zapp Group is your worldwide guarantee of
outstanding service and of the availability of our semi-
finished products. From America to Scandinavia to
China, in production facilities, service centers and sales
offices around the globe, our own staff and affiliated
partners are at your service to respond as quickly as
possible to your delivery requests. We overcome time-
consuming logistical obstacles through the continuous
expansion of our distribution network and service
centers. Selected partners ensure reliable transport over
land, air and sea to deliver our materials to your location
on-time. Express delivery services are also available for
direct delivery of samples and small lots to meet short-
term needs. We offer a wide range of packaging options
specifically designed to facilitate transport and protect
quality from the shipping department to the final
destination.
QUALITY
Products made to satisfy the highest quality demands form
the core of our corporate philosophy. It takes raw materi-
als from qualified production sources to manufacture safe
and reliable products for the medical and dental industry.
Zapp guarantees documented product traceability from
the original melt right through to the final semi-finished
product. The systematic archiving of documentation and
retention samples enables us to assure you unequivocally
of the quality of our products, even decades later.
And, thanks to our expert staff’s many years of experience
in research, development and manufacturing, we offer un-
surpassed product reliability that satisfies the extremely
sensitive demands placed on medical semi-finished pro-
ducts. We combine validated manufacturing processes
with integrated test technology and continuous monitor-
ing by our own trained team of specialists to maintain
these high material quality standards. Our products are
clearly designed to meet your specifications and comply
with qualitative requirements from the relevant standards
for medical semi-finished products. Beyond regulatory
requirements, the highest quality levels are achieved
through specifically targeted chemical compositions in
combination with highly specialized process engineering
technology.
