Coated polished aluminum sheet plate alloy
The quest for the perfect material in architecture and manufacturing is ongoing, with one alloy making significant waves in recent years: coated polished aluminum sheet plate alloy. With its glossy finish and versatile applications, this alloy stands at the intersection of form and function, balancing durability with aesthetic appeal. Here, we explore the unique dimensions of this innovative material, focusing on its properties, versatility, applications, and some standards in its production and use.
Defining the Alloy
At its core, coated polished aluminum sheet plate alloy is made from a combination of aluminum and a selected alloying element—commonly magnesium or silicon. During the manufacturing process, the alloy is precoated and polished, producing a surface that boasts both an appealing shine and excellent protective qualities. This multi-faceted process not only enhances its visual qualities but also improves resistance to wear and environmental conditions.
Properties
Several parameters define coated polished aluminum, making it desirable across a spectrum of industries:
| Property | Value |
|---|---|
| Density | ~2.73 g/cm³ |
| Yield Strength | 70–580 MPa |
| Ultimate Tensile Strength | 200-400 MPa |
| Elongation at Break | Approximately 4-20% |
| Melting Point | 660°C (1220°F) |
| Thermal Conductivity | 205–235 W/m·K |
| Corrosion Resistance | High (avg. 5.0-10.0 μm) reflective oxide layer |
The lightweight nature of aluminum, combined with the strengthening effects of alloying elements, gives coated polished aluminum exceptional mechanical properties. Its surface coating enhances corrosion resistance, which is particularly advantageous in unfavorable environments or when subjected to climatic variations.
Applications
Thanks to its balanced characteristics, coated polished aluminum finds applications in a wide range of industries, from construction and automotive to consumer electronics and packaging. Here’s a closer look at specific sectors that benefit from its unique properties:
