As a professional aluminum coil supplier, we bring you a detailed performance introduction of 1100 H14 aluminum coil to help you fully understand the advantages and characteristics of this product so that you can make wise decisions in purchasing and application.
1100 H14 aluminum coil belongs to the pure aluminum series. The aluminum content in its material composition is not less than 99.00%. It also contains a small amount of impurity elements such as iron and silicon. The content of these impurity elements is controlled within the standard range to ensure the stability of the material performance. H14 indicates the work hardening state of the aluminum coil, that is, it is incompletely annealed after work hardening (cold working) to give it medium strength and good formability. The density of this product is about 2.7g/cm³, the melting point is between 643-657℃, and it has good thermal conductivity and electrical conductivity. The thermal conductivity coefficient is about 237W/(m・K) and the electrical conductivity is about 61% IACS.
I. Mechanical properties
In terms of mechanical properties, 1100 H14 aluminum coil exhibits medium strength and good ductility. Its tensile strength (σb) is between 130-170MPa, its yield strength (σ0.2) is not less than 105MPa, and its elongation (δ) is ≥8% (gauge length 50mm). Such mechanical properties enable the aluminum coil to adapt to a certain degree of deformation while bearing a certain load, and it is not easy to break. It is suitable for a variety of occasions that require bending, stretching and other processing.
II. Processing performance
1. Formability
1100 H14 aluminum coil has good forming performance. Due to its incomplete annealing treatment, the material retains a certain work hardening effect and has good plasticity. During the cold processing process, it can withstand various forming processes such as bending, stamping, and spinning, and can be made into various parts with complex shapes. After forming, the dimensional stability is good, the surface quality is excellent, and it is not easy to produce defects such as cracks and wrinkles.
2. Weldability
The aluminum coil has good welding performance. The weldability of pure aluminum is excellent. When welding 1100 H14 aluminum coil, various welding methods such as gas welding, argon arc welding, and resistance welding can be used. During the welding process, as long as the appropriate welding materials and process parameters are selected, a good welded joint can be obtained. The joint strength can reach more than 80% of the parent material strength, and the corrosion resistance of the welding area is similar to that of the parent material.
3. Machinability
The machinability of 1100 H14 aluminum coil is medium. Due to the low hardness of pure aluminum, it is easy to produce tool sticking during the cutting process, resulting in a high roughness of the machined surface. However, by selecting appropriate tool materials (such as high-speed steel, cemented carbide), tool angles and cutting parameters (such as cutting speed, feed rate, and cutting depth), the cutting performance can be effectively improved and a more ideal machining surface quality can be obtained.
III. Corrosion resistance
1100 H14 aluminum coil has excellent corrosion resistance, which is mainly due to the fact that a dense aluminum oxide protective film (Al₂O₃) can be quickly formed on the surface of pure aluminum. The thickness of the film is about 0.01-0.1μm, which can effectively prevent oxygen, moisture and corrosive media in the air from contacting the aluminum substrate, thereby protecting the aluminum coil from corrosion. In the atmospheric environment, whether it is rural atmosphere, urban atmosphere or marine atmosphere, 1100 H14 aluminum coil shows good corrosion resistance and is not easy to rust after long-term use. In freshwater and seawater environments, the aluminum coil also has certain corrosion resistance, but in seawater environments, due to the presence of chloride ions, the corrosion rate will be slightly faster. However, by taking protective measures such as surface coating and anodizing, its corrosion resistance in harsh environments can be further improved. In addition, in some non-oxidizing acids (such as hydrochloric acid, dilute sulfuric acid) and alkaline solutions, 1100 H14 aluminum coil will corrode to a certain extent, but it has good corrosion resistance in oxidizing acids (such as nitric acid).
IV. Surface quality and dimensional accuracy
1. Surface quality
The surface of the 1100 H14 aluminum coil provided by BCM ALU is smooth and clean, without obvious scratches, pits, oil stains, oxidation spots and other defects. After strict production process control and surface treatment, the surface of the aluminum coil presents a uniform metallic luster, which can meet various application scenarios with high requirements for surface quality, such as architectural decoration, electronic and electrical housing, etc.
2. Dimensional accuracy
In terms of dimensional accuracy, the thickness tolerance of 1100 H14 aluminum coil is controlled at ±0.02mm (thickness ≤1.0mm) or ±0.03mm (thickness > 1.0mm), the width tolerance is ±1.0mm, and the length tolerance is ±5.0mm (when delivered in fixed length). The coil has good straightness, with a side curvature of no more than 3mm per meter and a longitudinal warping of no more than 10mm/m, ensuring the dimensional stability and installation convenience of the aluminum coil during subsequent processing and use.
In summary, 1100 H14 aluminum coil has good comprehensive performance, and performs well in mechanical properties, processing properties, corrosion resistance, surface quality and dimensional accuracy. It is suitable for many fields such as construction, electronics, packaging, machinery manufacturing, etc., and can be used to make aluminum veneers, aluminum profiles, cans, radiators, various parts, etc. As an aluminum coil supplier, we are always committed to providing high-quality 1100 H14 aluminum coils, and can provide customized products and services according to the specific needs of customers to ensure that your various application requirements are met.
