The 1050 color coated aluminum sheet coil is an aluminum coil with a colored coating on its surface, primarily used in construction, decoration, and advertising fields. Its aluminum alloy composition is 1050, which possesses excellent corrosion resistance and workability. The color coating not only enhances aesthetics but also provides additional protection, making the aluminum sheet more durable in outdoor environments.
The 1050 Color Coated Aluminum Sheet Coil mainly consists of 1050 aluminum alloy, with an addition of 3%-5% magnesium element, which gives it better strength and ductility while maintaining a low density.
The 1050 color coated aluminum sheet coil is a composite aluminum material with a surface coated in colored finishes (such as RAL Traffic Red, wood grain, stone pattern, etc.), combining the physical properties of pure aluminum with the decorative and protective functions of coatings.
1050 color coated aluminum coil is a high-purity aluminum base material offering excellent corrosion resistance, formability, aesthetics, weather resistance, and recyclability. It is available in various sizes, tempers, and color options, making it an ideal choice for architectural, industrial, decorative, and packaging applications.
When selecting, attention should be paid to the coating type (PVDF is more durable), thickness tolerance, and surface flatness to match the specific application requirements.
Base Material Composition: 1050 belongs to the industrial pure aluminum series (1xxx series), with aluminum content ≥99.5% and trace elements mainly including Fe and Si.
Base Material Properties:
High plasticity, excellent corrosion resistance, good electrical and thermal conductivity, but low strength and not heat-treatable for strengthening.
Low density (2.71g/cm³) and remarkable lightweight characteristics.
What is 1050 aluminum grade?
The 1050 aluminum grade is an aluminum alloy that consists of 99.5% or higher aluminum content. It belongs to the 1000 series of aluminum alloys and is known for its outstanding corrosion resistance, high thermal and electrical conductivity, as well as good workability.
