1000 series aluminum alloys are widely used basic materials, primarily including 1050, 1060, 1070, and 1100 al alloy grades. They all share the common 1000 series characteristics of low cost, easy processing, and corrosion resistance. Differences in purity or trace alloying elements enhance ductility, strength, electrical and thermal conductivity, and other properties, making them suitable for diverse applications.
High Purity
1000 series aluminum alloys have an extremely high aluminum content, typically exceeding 99% purity. This characteristic gives them several key properties:
Low Density: Their low weight makes them suitable for applications where weight is a concern.
Good Elongation: While not the highest in strength, they offer excellent flexibility, preventing brittle cracking during processing or use due to excessive hardness, meeting the flexibility requirements of some components.
Stable Fatigue Strength: They exhibit stable performance under repeated stress, making them suitable for components subjected to long-term stress, reducing the risk of failure and ensuring long-term operation.
Outstanding processability
Easy Forming: It can be easily formed into complex shapes through processes such as stamping, bending, and stretching.
Widely adaptable surface treatment: Suitable for a variety of surface treatment processes. Anodizing enhances surface hardness and corrosion resistance; brushing and sandblasting enhance surface texture to meet diverse design requirements.
Reliable Welding: Excellent welding performance facilitates joining with other metals. This ensures overall product quality and stability in applications such as joining building steel structures to aluminum alloy components and connecting electronic equipment components.
Excellent Corrosion Resistance
1000 series aluminum alloys exhibit the strongest corrosion resistance among aluminum alloys. This is due to the dense aluminum oxide film formed on the surface of the high-purity aluminum matrix.
Significant Cost Advantages
1000 series aluminum alloys contain no complex alloying elements, resulting in a simple production process and lower costs. Compared to aluminum alloys containing multiple alloying elements and requiring complex manufacturing processes, they offer significant price advantages.
1100 aluminum alloy
Aluminum purity: It is ≥99.00%, slightly lower, and contains trace amounts of copper (0.05%-0.20%). Aluminium 1100 is the only type in the 1000 series to contain copper.
Key Features: Its strength is 10%-15% higher than 1050 and 1060 aluminum alloys, while maintaining good formability and weldability, making it suitable for applications requiring slightly increased strength.
Typical applications: small compressed air storage tanks, heat exchange fins (moderate strength), industrial thick-walled aluminum tanks, outdoor aluminum alloy grilles, guardrails,etc.
