1100 Kepingan Aluminium untuk Dijual: Gred, Saiz dan Panduan Pembeli
Pengenalan
1100 aluminum sheet is one of the most practical commercially pure aluminum plates you can buy: with a minimum 99.0% aluminum content and a small copper addition, it is slightly stronger than 1050/1060 while keeping excellent formability, rintangan kakisan, weldability and thermal conductivity.
It is the default sheet for chemical equipment, cookware and deep-drawn parts, sink haba, signs and general fabrication that do not need high strength.
Offered factory-direct, 1100 sheet can be supplied in standard 4×8 ft and metric sizes or cut to your dimensions, with the temper and surface finish the product needs.
This guide covers the composition, sifat, sizes and weights, aplikasi, fabrikasi, bagaimana ia dibandingkan dengan 1050, 1060 dan 3003, dan cara nak order.
Apa Itu 1100 Lembaran Aluminium?
1100 is a non-heat-treatable 1xxx-series alloy strengthened only by cold work and softened by annealing. Sheet generally runs about 0.2–6 mm thick (thicker material is plate), supplied flat or cut to length. Kelebihan cirinya ialah:
- Kemuluran yang sangat baik untuk lenturan, setem, berputar dan lukisan dalam, terutamanya dalam perangai O.
- Very good atmospheric and chemical corrosion resistance from the self-healing oxide film.
- Kekuatan yang lebih tinggi sedikit daripada 1050/1060 thanks to a controlled 0.05–0.20% copper addition.
- High thermal and electrical conductivity, plus excellent weldability and easy machining.
- Cahaya (kira-kira 2.71 g/cm³), rust-free and lower cost than alloyed grades; anodizes to a good film.
- The trade-off is modest strength; load-bearing or wear parts should use 3003, 5052 atau 6061.
Komposisi Kimia dan Sifat Mekanikal
Kimia terkawal (per ASTM B209 / GB/T. 3190) keeps silicon plus iron and copper within tight limits so forming, welding and corrosion performance stay high:
| unsur | Al | Dan + Fe | Cu | Mn | Zn |
| 1100 | ≥99.0 | ≤0.95 | 0.05–0.20 | ≤0.05 | ≤0.10 |
Mechanical properties change with temper, jadi sama 1100 helaian boleh dibekalkan lembut dan boleh ditarik dalam atau keras dan tegar (typical Rm values):
| perangai | Tegangan (MPa) | Perwatakan |
| O (Annealed) | lebih kurang. 75-110 | Paling lembut; lukisan dalam, berputar, kebolehbentukan maksimum |
| H12 / H22 | lebih kurang. 95–125 | Suku keras; pembentukan cahaya |
| H14 / H24 | lebih kurang. 110-150 | Separuh keras; common general-purpose temper |
| H16 / H26 | lebih kurang. 135–170 | Tiga suku keras; panel yang lebih keras |
| H18 | lebih kurang. 150–200 | Penuh-keras; tegar, pembentukan terhad |
Nilai berbeza sedikit dengan ketebalan dan standard; confirm tensile and yield on the mill certificate for your gauge.
The small copper addition is what distinguishes 1100 in service.
It gives a modest but useful gain in strength without sacrificing the pure-aluminum forming that lets the sheet be drawn into deep pots and liners, and the metal still anodizes into a uniform, protective film used on trim and nameplates.
1100 thus occupies a deliberate middle ground—not as soft and conductive as 1060, but not as alloyed as 3003, which is why it appears so often in cookware, chemical and general-purpose stock.

Aplikasi biasa
- Peralatan proses kimia, tangki simpanan, kapal, pipes and fittings that need corrosion resistance and weldability.
- Alat memasak, cooking utensils and deep-drawn or spun parts, plus aluminum circles for pots and pans.
- Tenggelam haba, pemantul lampu, stok penutup botol, printing plates and food packaging components.
- Tanda-tanda, nameplates and decorative or anodized architectural trim, and general stamped or bent parts.
Fabrication and Surface Treatment
1100 cuts, shears, bends and forms readily and can be laser, plasma or water-jet cut, dicap, spun and drilled; it welds cleanly by common processes and takes anodizing, memberus gigi, polishing and coating well.
Use O temper for the deepest draws and harder tempers where the finished part must hold shape; generous bend radii and clean, oil-free surfaces help on high-speed lines.
1100 lwn 1050, 1060 dan 3003
| Gred | Min. Al / aloi | Kekuatan | Paling sesuai |
| 1050 | 99.50% Al | Rendah | Most economical general sheet and cladding |
| 1060 | 99.60% Al | Rendah | Best conductivity/reflectivity; signs and electrical parts |
| 1100 | 99.00% Al, sedikit Cu | Rendah-sederhana | Lebih kuat sedikit; membentuk, mengimpal, kimia, alat memasak |
| 3003 | Al + Mn (kira-kira 1.2%) | Medium | Mengenai 20% lebih kuat; lantai, tread, tougher cladding |
Pilih 1100 when you need a little more strength and weldability than 1050/1060 with the same pure-aluminum forming and corrosion; melangkah ke 3003 for real added strength.
Kawalan kualiti, Pricing and How to Order
QC covers thickness and flatness, toleransi lebar/panjang dan pepenjuru, surface quality and tensile/yield by temper and chemistry on the MTC; ISO 9001 mills support SGS/BV inspection.
Sheet is interleaved with protective film and packed on pallets or in cases with moisture-proof wrapping for export. Harga mengikut asas jongkong aluminium serta bayaran pemprosesan, with thinner/wider gauge, pemotongan tersuai, rawatan permukaan dan kuantiti yang kecil menambah kos;
compare per ton and per finished blank on identical specs under FOB/CFR/CIF (lazimnya 30% deposit, baki terhadap bil muatan). Untuk memetik, hantar aloi/temper (1100), ketebalan, lembaran atau dimensi kosong, permukaan, kuantiti, aplikasi dan pelabuhan destinasi.
Verify new material on production-gauge samples rather than photos: run the sheet through your forming, welding or cutting line at normal speed, mengukur ketebalan merentasi lebar, inspect the surface and, for food or chemical use, confirm the compliance paperwork matches the lot.
A signed pre-production sample then becomes the receiving standard, and an integrated mill that rolls and finishes in-house will hold that standard more reliably across repeat orders than spot resellers.
