Mirror aluminum sheets such as 1050 and 1100 grades are highly coveted in various industries due to their exceptional reflective finish, corrosion resistance, and lightweight properties. These sheets provide outstanding aesthetics and practical performance, making them a preferred choice across commercial, architectural, and industrial applications.
What is Mirror Aluminum Sheet?
A mirror aluminum sheet is an aluminum product with a polished surface similar to a mirror. Highly reflective and smooth, these sheets offer an elegant appearance along with the structural benefits of aluminum. The 1050 and 1100 grades are categorized under commercially pure aluminum, containing high aluminum content which enhances their workability and corrosion resistance.
Functions and Features of 1050 and 1100 Mirror Aluminum Sheets
Highly Reflective Surface
The primary feature is the mirror-like finish obtained through precision polishing techniques. It provides a decorative, shiny surface that is resistant to tarnishing.Corrosion Resistance
Both 1050 and 1100 grades offer excellent resistance to atmospheric corrosion, scale, and oxidation, suitable for long-term use in varied environments.Excellent Workability
Due to their high aluminum content, these sheets are soft and ductile, allowing effortless cutting, bending, and rolling.Lightweight yet Durable
Aluminum’s low density ensures lightweight materials without compromising strength, which allows easy handling and installation.Non-toxic and Eco-Friendly
Being non-toxic makes these mirror sheets ideal even for food and pharmaceutical applications.
