Aluminium Sheet Roll: Comprehensive Guide and Applications

Introduction

Aluminium sheet roll is a versatile and widely used material in various industries, particularly in construction, transportation, manufacturing, and packaging. Its exceptional strength-to-weight ratio, corrosion resistance, and formability make it a preferred choice for a broad range of applications.

Properties of Aluminium Sheet Roll

Aluminium sheet roll is manufactured by rolling aluminium ingots into thin, flat sheets. The properties of aluminium sheet roll vary depending on its composition and temper, which is the result of heat treatment and alloying.

Key Properties

• Strength and Rigidity: Aluminium sheet roll has a high strength-to-weight ratio compared to other metals, making it lightweight and durable.
• Corrosion Resistance: Aluminium's natural oxide layer provides excellent corrosion resistance, making it suitable for outdoor applications and harsh environments.
• Formability: Aluminium sheet roll is highly malleable and ductile, allowing it to be bent, shaped, and formed into complex shapes without cracking or breaking.
• Reflectivity: Aluminium sheet roll has a high reflectivity for light and heat, contributing to its use in lighting fixtures and thermal insulation.
• Electrical Conductivity: Aluminium sheet roll has good electrical conductivity, making it useful in electrical applications.

Temper Designations

Aluminium sheet roll is classified into different tempers based on its heat treatment and alloying. Temper designations are indicated by a one-letter code:

• O (Soft): Annealed, soft and ductile
• H (Hard): Cold-rolled, increasing strength and hardness
• H2 (Half-Hard): Partially cold-rolled, balance of strength and formability
• H4 (Quarter-Hard): Further cold-rolling, increased strength
• H6 (Fully Hard): Fully cold-rolled, maximum strength and hardness
