Aluminum Strip

Aluminum strips are used in industrial products. The raw materials of aluminum strips are pure aluminum or aluminum alloy cast aluminum coils, hot-rolled aluminum coils, which are cold-rolled on a rolling mill to produce thin aluminum coils of different thicknesses and widths, and then longitudinally slit into aluminum strips of different widths according to their applications.

Common alloy grades of aluminum strips include 1050, 1060, 3003, 5052, etc. According to the annealing state, they are divided into O state (soft) and H state (hard). The thickness usually ranges from 0.1 to 6 mm, and the width can be customized. They feature lightweight, corrosion resistance, and high conductivity, and are widely used in industrial, electronic, automotive, and construction fields.

Different alloys of aluminum strips (Aluminium strip) have differentiated properties. For example, 5052 alloy is suitable for vehicle components, 3003 alloy is mostly used for chemical equipment and heat exchangers, and O state aluminum strips are widely used due to their ease of processing. Haomei aluminum strip products cover pure aluminum strips, rust-resistant aluminum strips, and ultra-hard aluminum strips, with a thickness range of 0.1-6.0mm, a width of up to 2000mm, and support for customized slitting processing.

The raw materials for electronic products are no longer solely dependent on copper strips. Since aluminum’s conductivity is only slightly lower than copper, using aluminum strips as a replacement for copper strips is becoming a popular trend.

Classification by Temper State

According to the different annealing states of aluminum strips, they can be divided into fully soft (O state), half-hard (H24), and fully hard (H18). The most commonly used are the fully soft series because the O state is easier to stretch and bend.

Categories of aluminum alloy strips include: pure aluminum strips, transformer aluminum strips, ultra-hard aluminum strips, fully soft aluminum strips, half-hard aluminum strips, and rust-resistant aluminum strips.

Common Aluminum Strip Metal Temper

The common states of aluminum strips are O state and H state. O means soft state and H means hard state. O and H can be followed by numbers to indicate the degree of softness, hardness and annealing degree.

• O
• H24
• H18

According to the different annealing states of aluminum strips, aluminum strips can be divided into full soft (o state), semi-hard (H24) and full hard (h18). The most commonly used should belong to the full soft series, because the O state is easier to stretch and bend.

Common aluminum strip alloy grades include 1050, 1060, 1070, 1100, 3003, 3004, 5005, 5052, 8011, etc. Common states include O state and H state. O indicates soft, H indicates hard. Numbers following O or H indicate the degree of softness/hardness or annealing.

Common alloys include:

• 1060 (Pure Aluminum): Aluminum content ≥ 99.6%, excellent conductivity and corrosion resistance, commonly used for transformer windings, armored cables, and heat sinks.
• 3003 (Aluminum-Manganese Alloy): Strong corrosion resistance, good workability, suitable for chemical equipment, heat exchangers, and architectural decoration.
• 5052 (Aluminum-Magnesium Alloy): Higher strength, used for automobile fuel tanks, ship sheet metal parts, and structural components.
• 8011 (Aluminum-Silicon Alloy): High temperature resistance, commonly used for packaging foil and electronic components.

How to Choose Aluminum Strips?

• Clarify the Application: Determine the intended use of the aluminum strip and select the appropriate alloy and temper. For example, soft (O state) is needed for deep drawing, while half-hard or fully hard may be required for heat sinks.
• Determine Specifications: Accurately measure or calculate the required thickness, width, and length.
• Choose a Supplier: Look for reputable aluminum manufacturers or distributors to ensure stable material quality and accurate composition.
• Check Surface Quality: A good aluminum strip should have a smooth and flat surface, free of scratches, oil stains, oxidation spots, and roller marks.
• Request a Material Certificate: Standard products come with a Material Test Certificate (MTC) to ensure the material meets specifications.

Purchasing Recommendations: Performance Matching

• Conductivity: Prefer alloys 1060 or 1100, with conductivity ≥ 60% IACS.
• Corrosion Resistance: For coastal or high-humidity environments, 3004 or 5052 alloys are recommended, with salt spray test ≥ 1000 hours.
• Workability: For complex forming (e.g., deep drawing), O state material with hardness ≤ 50HV is recommended.

Aluminum strips are a fundamental yet powerful industrial material. From everyday pharmaceutical packaging to high-end audio equipment, as well as critical industrial manufacturing and power transmission, they are indispensable. Their specific properties entirely depend on the aluminum alloy grade, heat treatment state, and size specifications used.

How to identify the quality of aluminum strips?

One way is to look at the edges of the aluminum film to see if it reflects light. High-quality aluminum films will not peel off after being covered at high temperatures, while low-quality aluminum films will peel off easily due to insufficient viscosity. Compare the glossiness of several samples under light and choose the one with the best gloss.
