Mill Finish 5052 H34 Aluminum Sheets
Mill finish refers to the surface condition of the aluminum sheet as it emerges from rolling mills, essentially retaining the original appearance minus additional treatments like anodizing or painting. This “natural” surface finish is slightly dull or matte with microscopic textures indicative of rolling marks—offering excellent base properties for further finishing or direct use in applications where cosmetic sheen isn't a priority.
Alloy Specification: 5052 Aluminum
The Alloy 5052 is among the most popular non-heat-treatable aluminum-magnesium alloys owing to its:
- Superior corrosion resistance, especially in marine and saltwater environments
- Good fatigue strength
- Moderate static strength combined with enhanced workability.
This balance makes 5052 an industry-standard choice for structural panels, shipbuilding components, pressure vessels, and more.
Thickness and Temper Designation: Why 3mm and H34?
The 3mm thickness classifies this as a mid-gauge sheet optimal for moderate strength applications. It’s flexible enough to form complex shapes yet structurally capable of sustaining significant mechanical stress.
The temper H34 denotes a strain-hardened and partially annealed condition, specifically representing about 1/4 hard temper. More technically:
- "H" stands for strain-hardened and then stabilized (partially annealed)
- "3" represents degree of hardening (Medium strain-hardening)
- "4" specific variant conforming to industrial standards.
The H34 temper strikes a perfect balance between hardness and ductility, delivering enhanced strength without sacrificing bending or stretching functionalities—a crucial characteristic in demanding applications such as marine hulls or transportation panels.
The performance of 5052 H34 aluminum sheet is deeply linked to its elemental constitution. The precise control of this chemistry ensures the reliability needed in critical fields:
| Element | Content (%) | Role |
|---|---|---|
| Aluminum (Al) | Balance (around 97.25-98.65) | Base matrix providing ultimate lightness |
| Magnesium (Mg) | 2.2 - 2.8 | Primary strength and hardening alloying element |
| Chromium (Cr) | 0.15 - 0.35 | Improves corrosion resistance and stability |
| Iron (Fe) | ≤ 0.4 | Trace impurity—affects hardness marginally |
| Silicon (Si) | ≤ 0.25 | Minor improves castability but tracked closely |
| Copper (Cu) | ≤ 0.1 | Restricted to avoid reduced corrosion properties |
| Manganese (Mn) | ≤ 0.1 | Minor strengthening |
Meeting international standards, including ASTM B209 & AMS 4045, the mechanical qualities are honed to meet or exceed predefined cutting-edge criteria.
Standards and Implementation Norms
ASTM B209 is the specification used for aluminum and aluminum-alloy sheet and plate products. Our 5052 H34 sheet meets dimensions, mechanical valuations, and surface markings accordingly, ensuring easy compatibility for fabrication workflows globally.
The sheet is typically certified and tested for:
- Tensile in the range of 31ksi (215MPa) minimum yield strength
- Elongation around 6-12%
- Corrosion resistance validated in artificial salt spray and humidity studies
Distinctive Advantages of Using Mill Finish 5052 H34 Aluminum Sheet
From an application viewpoint:
- The Mill Finish surface gives modest protective quality during transport and initial fabrication and is easier for adhesion of paints or adhesives.
- The 3mm thickness suits structural layers where both rigidity and lightweight thickness-saving are required.
- By selecting H34 temper, fabricators receive increased dimensional stability during bending, allowing less spring-back, which is costly during repetitive manufacturing cycles.
