Co to jest aluminium 1100?
1100 aluminum is a commercially pure aluminum alloy with excellent formability and corrosion resistance. It is commonly used in chemical and food processing, and in applications where ductility matters more than strength. Being ductile and weldable, it appears in heat exchangers, cooking utensils, and reflectors.
Skład pierwiastkowy stopu Alloy 1100
Alloy 1100 is at least 99.0% aluminum, which gives it the lightweight and corrosion-resistant character typical of pure aluminum. Trace iron and silicon are present from production, while a small copper content adds a modest strength benefit.
This composition yields an alloy that machines acceptably, welds well, and resists corrosion, making it a common choice across industrial sectors.

Porównanie stopu 1100 z innymi stopami aluminium
Understanding how 1100 compares with other grades helps you select the right material. The comparisons below highlight where 1100 excels and where another alloy may fit better.
Stop aluminium 1100 vs. 1050
| Cecha | 1100 Stop aluminium | Stop aluminium 1050 |
|---|---|---|
| Makijaż główny | 99% Aluminum + small copper | 99.5% Aluminium (czystsze) |
| Siła | ~90–120 MPa | ~75–110 MPa |
| Odporność na korozję | Doskonały | Doskonały |
| Przewodność elektryczna | 59–62% IACS | 61–63% IACS |
| Wykonalność | Easy to bend and shape | Easy to bend and shape |
| Typowe zastosowanie | Wire, foil, light parts | Patelnie do gotowania, reflektory |
1100 i 1050 Aluminium are both near-pure aluminum grades with excellent formability. 1100 carries a small copper content that gives slightly higher strength (90–120 MPa vs 75–110 MPa), while 1050 is purer (99.5%) and marginally more conductive (61–63% IACS vs 59–62%). Both resist corrosion well. Choose 1100 for wire or foil where a bit more strength helps; choose 1050 for pans and reflectors where purity and conductivity matter.
Stop aluminium 1100 vs. 3003
| Cecha | 1100 Stop aluminium | Stop aluminium 3003 |
|---|---|---|
| Makijaż główny | 99% Aluminum + small copper | Al + 1% Mangan |
| Siła | ~90–120 MPa | ~110–145 MPa |
| Odporność na korozję | Doskonały | Bardzo dobry |
| Przewodność elektryczna | 59–62% IACS | 40–50% IACS |
| Wykonalność | Easy to bend, very formable | Łatwy do zginania, nieco sztywniejszy |
| Typowe zastosowanie | Wire, foil, light parts | Naczynia kuchenne, zbiorniki, bocznica |
1100 i Aluminium 3003 are both light and corrosion resistant. 1100 is purer (99%) and softer, with lower strength (90–120 MPa vs 110–145 MPa) than manganese-bearing 3003. 1100 conducts better (59–62% vs 40–50% IACS) and forms more easily. Use 1100 for conductive, flexible parts like wire and foil; use 3003 for cookware, tanks, and siding where more strength is needed.
1100 vs. stop aluminium 5052
| Cecha | 1100 Stop aluminium | Stop aluminium 5052 |
|---|---|---|
| Makijaż główny | 99% Aluminum + small copper | Al + 2,5% Magnez |
| Siła | ~90–120 MPa | ~190–260 MPa |
| Odporność na korozję | Doskonały | Excellent (good in saltwater) |
| Przewodność elektryczna | 59–62% IACS | 30–35% IACS |
| Wykonalność | Very easy to bend and shape | Dobre, ale sztywniejsze niż 1100 |
| Typowe zastosowanie | Wire, foil, light parts | Kadłuby łodzi, panele, mocniejsze części |
1100 i Aluminium 5052 serve different needs. 1100 is soft and light (90–120 MPa) and highly formable, with good conductivity (59–62% IACS). 5052, with magnesium, is much stronger (190–260 MPa) and performs well in saltwater, so it is common in marine and panel work. 1100 bends more easily; 5052 is stiffer but tougher. Pick 1100 for light, flexible, electrical parts; pick 5052 for stronger, heavy-duty components.
Kiedy wybrać stop aluminium 1100: Szybka lista kontrolna
| Czynnik | Dlaczego to ma znaczenie | Choose 1100 If… |
|---|---|---|
| Potrzeby w zakresie siły | Low strength limits load-bearing use. | You only need light strength (~90–120 MPa). |
| Wykonalność | Excellent cold formability. | You want to form complex shapes. |
| Odporność na korozję | Performs well in damp or outdoor use. | The part is exposed to weather or moisture. |
| Przewodność elektryczna | Good current-carrying capacity. | You need wire or conductors (59–62% IACS). |
| Transfer ciepła | Efficient thermal conduction. | You need heat sinks or radiators. |
| Koszt | Lower cost than stronger alloys. | You want to control material cost. |
| Waga | Low density, 2.71 g/cm³. | Low weight is a priority. |
Heads-Up: If your project needs high strength or toughness, such as structural or heavy-duty parts, skip 1100 and consider alloys like 5052 or 6061 instead.

Często zadawane pytania
Dlaczego stop Alloy 1100 jest preferowany do zastosowań w przemyśle spożywczym?
1100’s corrosion resistance helps prevent contamination, and the alloy is non-toxic, which makes it suitable for food-contact items such as cookware and packaging. Its formability also supports thin, easy-to-clean surfaces.
Czy Alloy 1100 może być używany na zewnątrz?
Yes. Its corrosion resistance and durability suit outdoor use, and it withstands normal weather conditions, which makes it reliable for external components and trim.
Jak wypada przewodność stopu Alloy 1100 w porównaniu z innymi stopami?
1100 has high electrical and thermal conductivity. Its electrical conductivity is 59–62% IACS (about 60% of copper), while its thermal conductivity of 218–225 W/m·K exceeds many other aluminum alloys, making it a cost-effective choice for efficient energy transfer.
Jakie techniki spawania są odpowiednie dla stopu Alloy 1100?
1100 has excellent weldability and joins easily with conventional methods such as TIG (GTAW) and MIG (GMAW). Its good workability and low strength make welding straightforward without special pre-treatment.
Czy istnieją jakieś ograniczenia w stosowaniu stopu Alloy 1100 w zastosowaniach morskich?
Although 1100 resists corrosion well, its lower tensile strength can limit use in structural marine parts that face high stress. For larger or load-bearing marine components, a stronger grade such as 5052 is usually better.
