Mirror Finish Aluminium Sheet 1070
Mirror Finish Aluminium Sheet 1070 is an exceptionally reflective aluminum product known for its aesthetic appeal combined with outstanding durability and corrosion resistance. It is widely favored across various industries where both visual impact and material performance are critical.
What is Mirror Finish Aluminium Sheet 1070?
Aluminium Alloy 1070 is a commercially pure aluminum grade with excellent corrosion resistance, high ductility, and good thermal and electrical conductivity. When its surface is polished to a mirror finish—achieving a smooth and highly reflective surface—this material ultimately becomes a sought-after option for both practical and decorative uses.
Typically processed via rolling or cold-rolling and subjected to surface treatments, Mirror Finish Aluminium Sheet 1070 delivers a gleaming finish that resists oxidation and oxidation of color changes over time.
Functions and Advantages
- Superior Reflectivity: The high-gloss mirror finish offers reflective properties for optical applications and aesthetically pleasing surfaces in architectural projects.
- Corrosion Resistance: Thanks to its purity level (>99%) and protective oxide layer, the 1070 aluminum offers outstanding resistance especially against atmospheric corrosion.
- Lightweight yet Strong: Easily machinable and lightweight without compromising significant structural integrity.
- Formability: It has excellent formability due to its low alloy content, making it ideal for complex shapes and metal forming processes.
- Thermal and Electrical Conductivity: Retains excellent conductive properties crucial for electrical components and heat exchangers.
