Aluminum foil is widely used in tape applications, especially in industries that require sealing, vật liệu cách nhiệt, and shielding. The choice of tape foil alloy depends on the desired characteristics, such as flexibility, chống ăn mòn, sức mạnh, và hiệu quả chi phí. The most common aluminum alloys for tape foil are 1235, 8011, and occasionally 8021.
Lá hợp kim nhôm 1235
Đặc trưng: High purity, with an aluminum content of at least 99.35%. Excellent flexibility and formability. High thermal and electrical conductivity. Chống ăn mòn tốt.
Các ứng dụng: 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.
Lá hợp kim nhôm 8011
8011 aluminum foil is a versatile aluminum alloy with balanced mechanical properties. Good strength and elongation ensure durability. High barrier to moisture, nhẹ, and gas. Chống ăn mòn tốt, especially in laminated or coated form.
en1235 lớp vv Temper Soft HO (đồng nhất ủ nhiệt thời gian giữ 440C, 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.
Lá hợp kim nhôm 8021
8021 offers higher strength and greater puncture resistance than 1235 và 8011. Excellent moisture and light blocking properties. Good elongation and formability.
Các ứng dụng:
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. thuộc tính rào cản:
All three alloys have excellent barrier properties, nhưng 8021 has superior moisture and light resistance for extreme applications.
3. Flexibility and formability:
1235 is the most flexible and easiest to process.
8011 và 8021 are slightly less flexible, but have better mechanical properties.
4. Trị giá:
1235 is the most economical choice for cost-sensitive applications.
8011 và 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, Thỏi nhôm đúc trống cán nóng được làm nóng và cán thành cuộn để cán nguội, chống ăn mòn, khả năng chịu nhiệt độ cao, 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.
