1050 Aluminum Coil

1050 aluminum coil belongs to the industrial pure aluminum series. According to international naming rules, its aluminum content must be ≥99.5% (the last two digits "50" indicate purity requirements). The main impurities are Fe and Si, while other trace elements such as Cu, Mg, and Mn are present in extremely low amounts.

1050 aluminum coil is a commercially pure forged aluminum alloy in the 1xxx series. It is widely used in industries that require corrosion resistance, electrical and thermal conductivity, high reflectivity, and formability, although its mechanical strength is relatively low compared to alloy grades.

1050 Aluminum Coil Characteristics

Chemical Composition: Mainly composed of aluminum (≥99.5%), with extremely low alloy element content. This composition ensures high purity, contributing to excellent electrical conductivity and corrosion resistance.
Physical Properties: Density is approximately 2.7g/cm³, and the melting point ranges from 646–660°C. Its high thermal conductivity makes it an ideal choice for applications requiring efficient heat dissipation.
Mechanical Properties: Due to its high purity, 1050 aluminum exhibits excellent ductility and machinability, but its mechanical strength is relatively low. Unlike metals with higher alloy content, it cannot be strengthened by heat treatment but instead relies on cold working (such as strain hardening) to improve its strength when necessary.
Surface Treatment: Its highly reflective surface benefits decorative and functional applications, such as light reflectors and building flashings.
