Metals used
General: All metals oxidize when exposed to air. The metals we use form different passive layers, which protect the underlying metal layers from further environmental influences. Frequent use of the writing instruments promotes the formation of a passive layer. Individual hand perspiration plays a role that should not be underestimated. Once the passive layer has formed, this condition is generally maintained. If the passive layer is damaged, e.g. by scratches, a new layer forms at the corresponding point.
Most ballpoint pen parts are polished. Aluminum is also often glass bead blasted. The surface becomes matt and has a more tactile texture. This surface treatment is often used for engraved pieces, making the engravings stand out more clearly. In some cases, blasted base materials are used and the other components are polished for contrast.
Stainless steel
gets an inconspicuous, thin oxide layer (= passive layer) and also retains its typical metallic appearance for a long time; it is slightly darker than aluminum. In contrast to bronze, this material retains its shine for a long time.
Properties:
- Weakly magnetic
- Conditionally suitable for seawater
- The materials are chromium-nickel steels with approx. 18% chromium and approx. 9% nickel. This corresponds to the nickel and chromium content of household items such as cutlery and stainless steel pans.
- Very durable
- Metallic gray coloring
- High strength
Nickel silver
can also acquire a delicate patina with frequent use. However, this takes a long time due to its high corrosion resistance. Nickel silver is somewhere between the other materials in terms of appearance. With frequent use, it does not appear quite as metallic as stainless steel and aluminum, but does not have the soft tone of bronze.
Properties:
- Nickel silver is the name for a copper-nickel-zinc alloy with high corrosion resistance, strength and a silver-like appearance.
- Nickel silver is also known as alpaca or argentan. The first metal goods came to Europe from China as early as the 17th century.
- Yellowish, golden coloration
- Non-magnetic
Bronze
Even when exposed to air, a passive layer will form relatively quickly. An individual and natural patina will also develop over time as a result of use. The polished bronze darkens to varying degrees, giving it its unique character. This gives the bronze its typical soft and warm hue, making the writing instrument more and more unique over the years.
Properties:
- Tin bronze with 92% copper and 8% tin content
- High strength and good spring properties
- The alloy is wear-resistant and has very good corrosion resistance. Bronze is resistant to: Sea air, drinking and process water, sea water.
- Known for approx. 6000 years = Bronze Age
- Non-magnetic and nickel-free
- Reddish, noble coloration
- Bronze is considered one of the best antibacterial metals due to its high copper content. Germs die more quickly due to the copper ions released.
Aluminum
quickly coats itself with a very resistant and protective oxide layer (= passive layer) and then retains its bright metallic appearance for a long time. Of all the metals used, writing instruments made of aluminum are real lightweights
Properties:
- Low susceptibility to corrosion
- Good strength properties
- Non-magnetic
- Nickel-free
- The low density results in very light writing instruments.
- Metallic gray coloring
Anodizing
Anodizing is an electrochemical process that creates a protective oxide layer on aluminium. This improves the corrosion resistance, hardness and wear resistance of the material. The porous layer can also be colored to achieve aesthetic effects.
Anodizing is a surface treatment for metals. It forms a protective oxide layer that makes the material more resistant to corrosion and wear, while at the same time allowing decorative colors.
silver
Silver is a precious metal that impresses with its excellent workability and high shine. It has a long tradition in the manufacture of high-quality writing instruments and gives every pen an elegant touch. Over time, silver develops a characteristic patina that emphasizes the individual charm of the material.
Properties:
- High corrosion resistance
- Antimicrobial properties
- Robust and durable surface
- Elegant, shiny appearance that develops a beautiful patina over time
Brass
Brass is an alloy of copper and zinc that is known for its high strength and excellent workability. It not only offers a beautiful, gold-like color, but also good resistance to corrosion. Brass writing instruments are robust and ideal for everyday use.
Properties:
- High strength and formability
- Good corrosion resistance
- Pleasant feel and warm colors
- Can be polished or patinated to achieve different looks
- Non-magnetic and nickel-free
Titanium
Titanium is an extremely strong and lightweight metal known for its exceptional strength and corrosion resistance. Commonly used in aerospace and medical applications, this material is perfect for writing instruments that combine durability and style. Titanium has a matt, elegant finish and offers a modern, industrial look.
Properties:
- Extremely high strength with low weight
- High corrosion resistance and durable
- Hypoallergenic and nickel-free
- Matt, elegant surface finish
- Very high temperature resistance
