Mill finish AA1100 1050 H18 H14 H24 color coated aluminum coil

12/06 2024

In today’s aluminum industry, the mill finish AA1100 and AA1050 color-coated aluminum coils stand out due to their remarkable properties and versatility. Manufactured using high-quality aluminum alloys, these materials cater to a variety of applications across numerous sectors.

Understanding Mill Finish AA1100 and AA1050

Mill finish refers to the initial stage of aluminum processing where the metal is fabricated into thin sheets or coils without any protective coating or enhancements. The AA1100 and AA1050 alloys represent specific grades in the aluminum industry.

AA1100:

This is a form of aluminum with around 99% purity, renowned for its excellent corrosion resistance and high thermal conductivity. Characteristics such as its light weight and ease of workability make it ideal for various industrial applications.

AA1050:

Slightly similar in composition, the AA1050 alloy is characterized by higher levels of aluminum (99.5% purity). It boasts similar benefits, but provides enhanced electrical conductivity, thereby making it particularly useful in electrical applications.

An Overview of H18, H14, and H24 Tempers

The designation of H18, H14, and H24 refers to the temper designation of aluminum, detailing the work hardening and heat treating that the metal undergoes during processing:

H14: It denotes that the aluminum has been partially hardened, providing increased strength and versatility for varied applications.
H18: Indicative of a further hardening process, H18 offers high tensile strength, which is key when employing in demanding environments.
H24: Classified as slightly soft material, H24 provides workability which is essential for applications needing flexibility during installation.
