THE VARIETY OF MATERIALS AND THEIR QUALITIES IN AERONAUTICAL LABELS AND PLATES
INTRODUCTION
In the world of aeronautics, every detail matters. From the majestic design of an aircraft to the discreet yet fundamental labels and plates marking each component, precision and safety are paramount. This article explores the importance of various materials used in the manufacture of aeronautical labels and plates, highlighting their essential qualities to ensure the safety, efficiency, and durability of aircraft.
MATERIALS USED IN AERONAUTICAL LABELS AND PLATES
ALUMINUM
Aluminum is one of the most widely used materials in the aeronautical industry due to its lightness and corrosion resistance. Particularly in the form of Metalphoto®, a photosensitive anodized aluminum, this material offers high durability and resistance to chemicals and abrasives, essential for tooling identification labels and structural components.
- Printing Type: Laser, screen printing, and intaglio.
- Colors: Laser allows one color, screen printing and intaglio allow all colors.
- Available Thicknesses: From 0.01 mm to 5 mm.
- Technical Characteristics: High tensile strength and temperature resistance.
STEEL
Known for its strength and durability, steel is used in areas requiring high tensile strength and wear resistance, such as landing gear and engine components.
- Printing Type: Laser, screen printing, and intaglio.
- Colors: Similar to aluminum, laser printing on steel allows one color, while screen printing and intaglio allow a wide range of colors.
- Available Thicknesses: From 0.01 mm to 5 mm
- Technical Characteristics: Excellent tensile, temperature, and radiation resistance.
TITANIUM
Titanium combines the lightness of aluminum with the strength of steel, along with excellent corrosion resistance, making it ideal for components subjected to high temperatures and stresses.
- Printing Type: Laser.
- Colors: Black, yellow, blue, red.
- Available Thicknesses: From 0.01 mm to 5 mm.
- Technical Characteristics: High temperature, radiation, and tensile strength.
VINYL AND POLYCARBONATE
Primarily used in aircraft interiors, these plastic materials offer flexibility and resistance to varying temperature and humidity conditions.
- Printing Type: Screen printing and thermal transfer.
- Colors: All colors.
- Available Thicknesses: Vinyl: From 0.1 mm to 0.8 mm; Polycarbonate: Variable.
- Technical Characteristics: Good temperature, radiation, and tensile resistance.
NECESSARY CHARACTERISTICS OF AERONAUTICAL LABELS
- Temperature Resistance: Labels must maintain their properties at extreme temperatures.
- Radiation Resistance: Especially UV radiation.
- Tensile and Abrasion Resistance: Essential in high-friction areas.
- Chemical Resistance: Must be chemically resistant to avoid deterioration.
OTHER MATERIALS AND TECHNOLOGIES
In addition to the materials mentioned, there are other options and technologies that complement safety and functionality in aeronautics:
- Polycarbonate: Impact and scratch-resistant, ideal for areas near passengers.
- Photoluminescent Labels: Visible in the dark, essential for safety in low light conditions.
- Tamper-Proof Labels: Prevent fraud by being irreparable once removed.
- Laser and Mechanical Engraving: For precise and durable identification.
CONCLUSION
The selection of appropriate materials for labels and plates in aeronautics is crucial for operational safety and efficiency. Each material, from aluminum to titanium, offers unique properties that ensure each aircraft component is clearly identified and protected against various environmental and mechanical conditions.
