Overview of 1050 Color-Coated Aluminum Sheet Coil
The 1050 color-coated aluminum sheet coil is a pre-painted aluminum product made from high-purity 1050 aluminum alloy, featuring a durable colored coating on the surface. It is widely applied in construction, decoration, advertising, packaging, and industrial manufacturing.
By combining the natural advantages of pure aluminum-such as corrosion resistance and workability-with advanced coating technology, this aluminum sheet coil delivers enhanced durability, weather resistance, and decorative value, particularly in outdoor environments.
1050 Aluminum Sheet Coil Base Material Characteristics
The base material of the 1050 aluminum sheet coil belongs to the 1xxx series industrial pure aluminum group, with an aluminum content of ≥99.5%. Trace elements mainly include iron (Fe) and silicon (Si).
Key Base Material Properties of 1050 Aluminum Plate
Excellent corrosion resistance
High plasticity and outstanding formability
Good electrical and thermal conductivity
Low density (2.71 g/cm³) for lightweight structures
Not heat-treatable for strengthening
These characteristics make 1050 aluminum sheet and plate products ideal for forming, bending, stamping, and coating processes.
What Is the 1050 Aluminum Grade?
The 1050 aluminum grade is a high-purity aluminum alloy containing at least 99.5% aluminum. It is well known for its superior corrosion resistance, high thermal and electrical conductivity, and excellent workability, making it a preferred choice for coated aluminum sheet coils used in architectural and industrial applications.
