About 3mm 1050 h24 aluminium sheet

What is 1050-H24 aluminum alloy?

1050 aluminum is part of the 1xxx series, the highest-purity aluminum available commercially. It typically contains not less than 99.5% aluminum, with trace elements kept to a minimum.

The 1050 alloy is prized for its superb ductility, exceptional corrosion resistance, and ease of fabrication. The temper designation “H24” indicates a work-hardened state that has been partially annealed to achieve a balanced combination of strength and formability.

In practical terms, 1050-H24 offers more yield strength and hardness than fully annealed 1050 (O or F), while still maintaining excellent formability for bending, stamping, and shallow drawing.

Key takeaways:
– Material family: 1xxx series (high-purity aluminum)
– Typical composition: ~99.5% Al, residual elements in trace amounts
– Temper: H24 (strain-hardened and partially annealed)
– Thickness focus: 3 mm (0.118 inches) is a common industrial thickness for exterior, interior, and structural applications requiring a sturdy yet light sheet

Why the temper designation matters

The H-series temper designations reflect how much work hardening has been applied. H24 sits between fully annealed (O) and heavily work-hardened (H), offering:
– Reasonable yield strength and tensile strength
– Good elongation, allowing for bending radii and forming without cracking
– Strong surface finish potential and excellent corrosion resistance
– Superior weldability relative to some higher-strength aluminum alloys

For design teams, this translates into a material that is predictable to form into panels, enclosures, housings, and decorative elements without sacrificing mechanical integrity.

Typical chemical composition and what it means for corrosion and formability

While exact compositions can vary by supplier and production batch, a typical 1050 alloy composition looks like:
– Aluminum (Al): ~99.5% min
– Silicon, iron, copper, manganese, magnesium: trace or very low quantities
– Other elements: controlled to meet purity and performance standards

Because of this high aluminum content and low impurity level, 1050-H24 demonstrates excellent corrosion resistance in atmospheric and most mildly corrosive environments.

It forms protective oxide layers readily, which helps resist degradation in outdoor and indoor settings. The trade-off is that strength remains lower than many other alloys (especially those in the 2xxx, 6xxx, and 7xxx families), but the material’s ductility and surface compatibility often outweigh this for applications like enclosures, reflectors, heat exchangers with thin walls, and decorative panels.

3mm Aluminium Sheet Thickness Measurement

Material properties and data

Understanding the mechanical, physical, and thermal properties of 3mm 1050 h24 aluminium sheet helps you forecast performance in real-world scenarios.

The following properties are representative and should be treated as typical ranges that vary by supplier, processing, and finishing.

Mechanical properties (typical ranges for 1050-H24)

Yield strength (0.2% offset): roughly 40–60 MPa
Ultimate tensile strength (Rm): roughly 90–125 MPa
Elongation at break (A80/A50): 12–25% depending on thickness and forming
Hardness (HB or Vickers, varies by scale): commonly in the 40–60 HB range for H24 temper

Notes:
– Values vary with processing history and exact heat treatment. Your supplier’s data sheet is the best source for exact numbers for a given batch.
– The 3 mm aluminum sheet often yields slight improvements in overall stiffness per unit weight compared to very thin gauges, but it remains well below the strength of high-strength 2xxx or 7xxx alloys.

Physical properties

Density: ~2.70–2.71 g/cm3
Melting point: ~660°C (1620°F) for pure aluminum
Specific heat capacity: ~0.9 J/g·K (approximate; depends on purity and heat treatment)

Thermal properties

Thermal conductivity: ~205 W/(m·K) at room temperature
Coefficient of thermal expansion (CTE): ~23.1×10^-6 /°C (typical for Al alloys)

These thermal properties make 1050-H24 suitable for applications where thermal conduction matters, such as heat transfer components, radiators, and certain high-emissivity exterior panels, while its high reflectivity can be advantageous for lighting fixtures and decorative panels.

Formability, machinability, and surface finish

Bending and forming: Excellent ductility, good for channels, enclosures, and panels with moderate bend radii
Cutting: Easy to machine with standard metalworking tools; chips are fine and curling tends to be manageable
Welding: Reasonable weldability for aluminum alloys; careful control of heat input minimizes distortion and potential loss of temper
Surface finishing: Good for mechanical finishing, anodizing, and coating. The H24 temper doesn’t prevent anodizing; it may yield a uniform surface color after finishing

Manufacturing and processing considerations

To maximize the performance of 3mm 1050 h24 aluminium sheet, you need to align manufacturing steps with its temper, thickness, and intended use.

The following subsections cover practical guidance for fabricators and engineers.

Forming and fabrication best practices

Bending radii: For 3 mm thick sheet, aim for minimum bend radii in the range of 3–4 times the sheet thickness (i.e., 9–12 mm) for clean bends without cracking in H24
Tooling: Use sharp, properly tuned tools; keep exit sheets and dies clean to prevent galling and tearing
Annealing considerations: H24 is partially annealed to maintain formability. Avoid over-work-hardening by controlling forming speed and tooling temperature
Surface handling: If bending leaves scratches, apply gentle deburring and consider maskings to protect finishes during assembly

Welding and joining guidelines

Welding processes: MIG (GMAW) or TIG (GTAW) are suitable for 1050-H24; keep heat input moderate to minimize distortion and maintain temper
Pre-weld treatment: Clean surfaces to remove oxides and oils; ensure oxide layers are removed at weld zones for good fusion
Post-weld finishing: Light mechanical smoothing if needed to preserve surface finish and avoid ductility loss near weld seams

Surface finishing and anodizing

Anodizing: 1050 alloys anodize well due to high aluminum content; evenly porous oxide layers form under controlled electrolyte conditions
Surface options: Brushed, mirror-polished, satin, or textured finishes can be applied depending on aesthetic and functional needs
Coatings: Primers, paints, or powder coatings adhere well with proper pretreatment; surface cleanliness is crucial for coating durability

Machining and cutting

Cutting methods: Shearing, laser cutting, plasma cutting, and waterjet cut are all common; laser and waterjet are preferred for precise, burr-free edges
Drill and hole operations: Use sharp drill bits and slow feed rates to prevent work-hardening at the edge and distortion
Tolerance considerations: Expect tolerances around ±0.15–0.30 mm depending on equipment and finishing; consult supplier specs for exact tolerances on 3 mm stock

Thermal and environmental considerations

Temperature stability: Aluminum’s aluminum-oxide layer provides robust corrosion resistance, but in very aggressive environments (industrial chemicals, salt spray, extreme temperatures) consider protective coatings or alloys with improved corrosion resistance
Thermal expansion: Expect noticeable dimensional changes with temperature; ensure design accounts for contraction/expansion

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.

Casting and rolling process

Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
3. The production speed is generally between 1.5m/min-2.5m/min;
4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.

Cold rolling production process

1. Cold rolling refers to the rolling production method below the recrystallization temperature;
2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.

Introduction to finishing production process

1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
