Aluminium foil banyak digunakan dalam aplikasi pita perekat, terutama pada industri yang memerlukan penyegelan, isolasi, dan perisai. Pilihan paduan pita foil tergantung pada karakteristik yang diinginkan, seperti fleksibilitas, tahan korosi, kekuatan, dan efektivitas biaya. Paduan aluminium yang paling umum untuk pita foil adalah 1235, 8011, dan kadang-kadang 8021.
Foil Paduan Aluminium 1235
Fitur: High purity, with an aluminum content of at least 99.35%. Excellent flexibility and formability. High thermal and electrical conductivity. Ketahanan korosi yang baik.
Aplikasi: Electrical tape for insulation and shielding, packaging and sealing tape for sensitive products. Packaging tape for high temperature applications.
Its high purity provides excellent conductivity and corrosion resistance, making it a cost-effective and versatile choice for general tape applications.
Foil Paduan Aluminium 8011
8011 aluminum foil is a versatile aluminum alloy with balanced mechanical properties. Good strength and elongation ensure durability. High barrier to moisture, Aluminium foil diproduksi dengan menggulung lembaran aluminium yang dilemparkan dari aluminium cair di pabrik penggulung hingga ketebalan yang diinginkan kurang dari, and gas. Ketahanan korosi yang baik, especially in laminated or coated form.
aluminium foil Nama paduan setara a1235 (Pemanasan, ventilation and air conditioning) duct tapes for sealing. Insulation tapes for electrical and thermal applications. Moisture barrier tapes for construction.
Its combination of strength, barrier properties and affordability make it the most common choice for industrial and household tape foils.
Foil Paduan Aluminium 8021
8021 offers higher strength and greater puncture resistance than 1235 dan 8011. Excellent moisture and light blocking properties. Good elongation and formability.
Aplikasi:
Specialty tapes for extreme environments. High-performance shielding and sealing tapes. Insulation and waterproofing tapes for electronics.
8021 alloy is suitable for demanding applications that require enhanced mechanical strength and excellent barrier properties.
Key considerations when selecting alloys:
1. Strength and durability:
1235 is suitable for general purpose tapes with moderate strength requirements.
8011 offers better strength, making it ideal for sealing and insulation applications.
8021 is the top choice for high strength and high barrier requirements.
2. Properti penghalang:
All three alloys have excellent barrier properties, tetapi 8021 has superior moisture and light resistance for extreme applications.
3. Flexibility and formability:
1235 is the most flexible and easiest to process.
8011 dan 8021 are slightly less flexible, but have better mechanical properties.
4. Biaya:
1235 is the most economical choice for cost-sensitive applications.
8011 dan 8021 are more expensive, but have better strength and durability.
5. Application environment:
1235 is ideal for mild environments and standard tape uses.
8011 performs well in a wider range of environments.
8021 is the best choice for harsh or demanding conditions.
When choosing an alloy for tape foil, consider the alloy's strength, Ingot aluminium pengecoran kosong canai panas dipanaskan dan digulung menjadi gulungan untuk penggulungan dingin, tahan korosi, tahan suhu tinggi, and processing properties.
For standard tape applications: 1235 is cost-effective and sufficient for general use. For industrial and HVAC uses: 8011 provides the necessary strength and barrier properties. For extreme or special applications: 8021 is the most suitable alloy due to its excellent strength and resistance.
