Aluminum Strip 1100 3004
1100 Aluminum Strip
Aluminum strip 1100 belongs to the pure aluminum series, with an aluminum content exceeding 99.0% and extremely low impurity content. This determines its core characteristics:
Performance advantages: It is of excellent plasticity and easy to cold-process through stamping, bending, stretching, and other processes. Anodizing can also be used to enhance the surface aesthetics. It is highly corrosion-resistant and rust-resistant in dry or slightly humid environments. It has good electrical and thermal conductivity, slightly inferior to pure copper, but at a lower cost, offering excellent value. However, its strength is relatively low, with a tensile strength of approximately 95-120 MPa, making it unsuitable for heavy loads.
Main Applications:
Packaging: It is often used as a base material for food and pharmaceutical packaging, aluminum foil meets food safety standards due to its high purity and lack of harmful substance release. Examples include chewing gum packaging and capsule aluminum-plastic panels.
Electronic Heat Dissipation: It is used as heat sinks for low-voltage electrical appliances and small transformers. Its excellent thermal conductivity allows for rapid heat dissipation, ensuring stable operation.
Decorations and Daily Necessities: After anodizing, it can be made into lamp housings, furniture trims, and kitchen utensils (such as lightweight soup spoons and colanders), achieving both aesthetics and practicality.
3004 Aluminum Strip
Aluminum strip 3004 is an aluminum-manganese alloy (containing 1.0%-1.5% manganese). It is a rust-resistant aluminum alloy with a performance focus on a balance of strength and corrosion resistance:
Performance Advantages: Its strength is significantly higher than 1100 aluminum strip, with a tensile strength of 180-220 MPa. This strength can be further increased through cold rolling. It offers excellent corrosion resistance, particularly in humid and salt-spray environments, such as those found at the beach or outdoors. It also offers excellent processability, suitable for complex stamping and forming (such as deep drawing). It also exhibits excellent weldability, enabling strong bonding to other metals and itself. However, its ductility is slightly lower than that of 1100 aluminum strip, making it slightly more difficult to cold-work.
Main Applications:
Container Manufacturing: It is the core material for cans (such as cola cans and beer cans), capable of withstanding the pressure of filling and resisting acid and alkali corrosion from beverages. Its lightweight design reduces transportation costs.
HVAC and water treatment: It is used in evaporator fins in air conditioners and refrigerators, improving heat exchange efficiency through its excellent thermal conductivity and resistance to condensate corrosion. It can also be made into water tanks and sinks for household or industrial use, resisting rust caused by long-term immersion in water.
Outdoor and Transportation: It serves as substrates for outdoor billboards, decorative parts for car trunks, or lightweight components for small boats, resisting wind, rain, and saltwater corrosion, extending its service life.
1100 vs. 3004 alloy
The differences between the two are primarily concentrated in five dimensions: In terms of core composition, 1100 aluminum strip is pure aluminum with an aluminum content of over 99%, while 3004 aluminum strip is an aluminum-manganese alloy containing 1.0%-1.5% manganese.
In terms of strength, 1100 aluminum strip is relatively weak, with a tensile strength of approximately 95-120 MPa, while 3004 aluminum strip roll is stronger, reaching a tensile strength of 180-220 MPa.
In terms of corrosion resistance, 1100 aluminum strip performs well in dry or slightly humid environments, while 3004 aluminum strip is more advantageous in humid and salt spray environments.
1100 aluminum strip is characterized by high plasticity and is easily cold-worked, while 3004 aluminum strip emphasizes toughness and is more suitable for processing methods such as deep drawing and welding.
There are also clear distinctions in their application scenarios: 1100 aluminum strip is suitable for light-load, high-purity applications, such as packaging and electronic heat dissipation, while 3004 aluminum strip is more suitable for medium-load, weather-resistant applications, such as container manufacturing and outdoor applications.
