Standard Alloys for Writing Instruments
Lebronze alloys Germany Precision Drawn Wire, Rod, Blanks, and Profiles
Lebronze alloys Germany manufactures specialty copper alloys with unparalleled precision, reliability, and the strongest productline.
Lebronze alloys Germany has achieved a worldwide reputation as a leading supplier to the writing instrument industry.
Product range
Lebronze alloys Germany’s product range includes:
•
•
•
•
•
•
wire and rod in brass and nickel silver for the production of ballpoint pen tips;
blanks in brass and nickel silver for the production of ballpoint pen tips;
new alloy NSA for cost reduction and “best writing pleasure” replacement of stainless steel ball point pen tips;
brass rods for machined barrels of pens;
brass rods for mechanisms (mechanical movement components);
profiles for drafting and drawing instruments.
Pay-off/De-coiler Systems
The wire is usually supplied in standard coils or in drums of about 250 to 400 kg. (500 to 800 lbs.) Our large packing with pay-off
de-coiling systems enables our customers to increase productivity by allowing higher feed speeds, longer run times, and reduce setup times.

Next Generation Cu-based Alloys
for Writing Instruments
Lebronze alloys Germany Innovation of High Strength & Ductility Nickel
Silver Alloys and Environmental-Friendly Products
Lebronze alloys Germany Research and Development Department releases patent pending new innovative alloy solutions, which show
improved properties suitable for various demands of writing instrument applications, including anti-corrosion alloys made for gel-ink
applications, high strength alloys suited for finest dimension of wires < 1.6 mm Ø, nickel silver alloy grades sustaining very high deformability suited for cold heading applications and environmental friendly alloys free of lead, bismuth, or beryllium.
Innovation Products
Lebronze alloys Germany’s R&D department focus lies in products that are:
•
•
•
•
high strength Next Generation Nickel Silver Alloy;
high formability New Nickel Silver Alloy (NSA) for cold-heading applications;
environmental-friendly Pb-free brasses (EnviB1) and Pb-free Nickel Silver (EnviN1) alloys conform with new legislation restricting the use of hazardous metals, such as Pb, Bi, or Be;
corrosion resistant pen tips suitable for water-based gel-ink applications;

High Strength & High Ductility Next Generation Nickel Silver

Eng. Strain [%]
The right choice of material combinations
The performance of pen tips is largely dependent on the right choice of materials combination: the ink, the ball material and the tip
material. Classically we differentiate the choice of combinations based on the type of ink: water-based gel inks with corrosion resistant
WC-balls and steel tips, or oil-based inks with common WC-balls and brass or nickel silver. Lebronze alloys Germany efforts in the
development of corrosion resistant nickel silver alloys suitable for oil-based and gel-based ink applications combined with the good
machinability and/or cold-headability will result in a higher added-value for the customer.
L
ebronze alloys group was born from the integration of
different companies specializing mainly in copper alloys but
also aluminium alloys and specialty steels.
Thanks to a multidisciplinary know- how, the group is today at
the heart of heavy industries such as Aerospace, Oil& Gas, Power,
Railway but also in sectors manufacturing smaller equipment and
products.
One of the group’s major strengths is based upon its
fully integrated production processes. All its products are
manufactured in 10 complementary facilities which all offer
industrial technologies (foundry, extrusion, forging, hot
stamping, wire drawing, machining, centrifugal casting). This
particularity guarantees a complete traceability and thus a
perfect control of quality.
With a task force of 1,100 persons, a turnover of € 220 million
(90% exports), over 150 alloys, more than 30,000 tons of foundry
capacity, 20,000 tons extrusion capacity, more than 100 machining
centers and dedicated Innovation & Research departments,
Lebronze alloys supports its customer from conception through to
fabrication of any kind of parts.
