Complete Guide to 1050 Aluminum Plate – Properties, Fabrication, and Applications
Looking for a high-purity aluminum solution for electrical, chemical, or architectural applications? GNEE 1050 aluminum plate is a commercially pure alloy with excellent conductivity, corrosion resistance, and formability. This article provides a comprehensive overview, covering chemical composition, mechanical and physical properties, temper options, product forms, standards, and typical applications to help engineers and designers make informed choices.
Comprehensive Overview of 1050 Aluminum Plate
1050 aluminum plate belongs to the 1xxx series of wrought aluminum alloys, with a minimum aluminum content of 99.5%. It is a high-purity, non-heat-treatable alloy designed for applications where corrosion resistance, electrical and thermal conductivity, and excellent formability are critical.
| Feature | Description |
|---|---|
| Aluminum Content | ≥99.5% |
| Alloying Elements | Si, Fe, Cu, Mn, Mg, Zn, Cr, Ti (controlled impurities) |
| Strengthening Method | Cold working (strain hardening) |
| Heat Treatment Response | Not heat-treatable |
| Key Traits | High electrical/thermal conductivity, corrosion resistance, ductility, weldability |
| Common Industries | Electrical/electronics, chemical processing, packaging, reflective surfaces, architecture |
The alloy's purity ensures predictable behavior under fabrication, making it suitable for deep drawing, forming, and conductive applications where surface finish and recyclability are essential.
Temper Variants of 1050 Aluminum Plate
Selecting the right temper for 1050 aluminum plate is a balance between strength and formability.
| Temper | Strength Level | Elongation | Formability | Weldability | Notes |
|---|---|---|---|---|---|
| O | Low | ≥35% | Excellent | Excellent | Fully annealed, maximum ductility & conductivity |
| H12 | Low-Medium | 20–30% | Very good | Excellent | Slightly strain-hardened |
| H14 | Medium | 8–15% | Good | Excellent | Common intermediate temper for moderate strength |
| H16 | Medium-High | 6–10% | Fair to Good | Excellent | Higher work-hardening for stronger components |
| H18 | High | 2–6% | Limited | Excellent | Near maximum commercial cold-work strength |
| F | Varies | Varies | Varies | Varies | As-fabricated condition, no special control |
Weldability remains excellent across all tempers since 1050 aluminum plate lacks heat-treatable precipitates. However, localized annealing in welded areas will restore O-temper ductility.
Chemical Composition of 1050 Aluminum Plate
| Element | Maximum % | Notes |
|---|---|---|
| Aluminum | 99.5 min | Ensures high conductivity and corrosion resistance |
| Silicon (Si) | 0.25 | Controlled impurity |
| Iron (Fe) | 0.40 | Influences strength & surface finish |
| Copper (Cu) | 0.05 | Preserves corrosion resistance |
| Manganese (Mn) | 0.05 | Minimal strengthening effect |
| Magnesium (Mg) | 0.05 | Almost no effect on precipitation hardening |
| Zinc (Zn) | 0.07 | Low to avoid embrittlement |
| Chromium (Cr) | 0.05 | Grain structure control |
| Titanium (Ti) | 0.05 | Grain refiner |
| Others | 0.15 | Total of remaining elements |
This composition ensures the 1050 aluminum plate delivers high ductility, superior conductivity, and excellent corrosion resistance while maintaining ease of fabrication.
Mechanical Properties of 1050 Aluminum Plate
| Property | O/Annealed | H14 Temper | Notes |
|---|---|---|---|
| Tensile Strength | 40–60 MPa | 80–120 MPa | Strength increases with cold working |
| Yield Strength | 20–35 MPa | 60–95 MPa | Yield rises nonlinearly with strain hardening |
| Elongation | ≥35% | 8–15% | O-temper has highest formability |
| Hardness | 15–25 HB | 25–40 HB | Hardness increases with H tempers |
Cold working enhances strength while reducing ductility predictably. Welded zones will locally soften H-temper material back to O-temper levels.
Physical Properties of 1050 Aluminum Plate
| Property | Value | Notes |
|---|---|---|
| Density | 2.71 g/cm³ | Lightweight material for easy handling |
| Melting Point | 635–660 °C | High-purity aluminum melting range |
| Thermal Conductivity | 220–240 W/m ·K | Excellent for heat sinks & exchangers |
| Electrical Conductivity | 58–62% IACS | Ideal for busbars & conductors |
| Specific Heat | 0.90 J/g·K | Useful in thermal management |
| Thermal Expansion | 23.6 µm/m ·K | Typical linear expansion for assemblies |
These properties make 1050 aluminum plate suitable for thermal management and power distribution applications.
Product Forms of 1050 Aluminum Plate
| Form | Typical Thickness/Size | Strength Behavior | Common Tempers | Notes |
|---|---|---|---|---|
| Sheet | 0.1–6 mm | Good planar strength | O, H12, H14 | Used in deep drawing, foil, cladding |
| Plate | >6 mm up to ~25 mm | Lower work hardening | O, H18 | Thicker conductive sections |
| Extrusion | Various | Depends on post-extrusion cold work | O, H12/H14 | Used for profiles requiring surface finish |
| Tube | Ø small to large | Thin-wall easily formed | O, H14 | Chemical handling & architectural tubing |
| Bar/Rod | Dia < 200 mm | Solid sections less responsive | O, H18 | Machining stock, conductor rods |
Sheet and coil remain the most common due to excellent O-temper formability; extrusion, plate, and rod are selected for specific conductivity or mechanical requirements.
Equivalent Grades of 1050 Aluminum Plate
