3003 H18 0.3mm Thin Aluminum Sheet

01/13 2025

In today's innovative manufacturing landscape, materials play a pivotal role in defining the performance and quality of products. Among these, the 3003 H18 0.3mm thin aluminum sheet stands out as a crucial player due to its unique combination of features.

the Alloy: 3003 H18

The designation ‘3003’ refers to a specific aluminum alloy series—known for its exceptional workability and moderate strength. This alloy, primarily composed of aluminum (95.7% to 98.9%), ensures good corrosion resistance and excellent machinability. The inclusion of manganese (1.0% to 1.5%) enhances its strength-to-weight ratio and response to multiple fabrication processes.

The ‘H18’ temper signifies that this sheet has undergone strain hardening with a significant degree of cold work. More specifically, the letter "H" denotes that the material has been heat-treated or work-hardened, ensuring it reaches peak strength through an enhanced resistance to deformation. The ‘18’ indicates the level of hardening; it applies a substantial strength yet maintains some ductility and formability.

The 0.3mm thickness makes this aluminum sheet exceptionally lightweight, yet still durable, which is germane to its successful performances in different environments.

Features That Matter

Corrosive Resistance: The nature of 3003 aluminum ensures resistance to atmospheric and chemical corrosive elements. This feature is paramount, as it significantly prolongs the lifespan of products in demanding conditions, making it ideal for both outdoor applications and elements exposed to moisture.
Surface Appearance: The thin gauge of the 0.3mm sheet provides not only functionality but also visual appeal. The smooth and aesthetically pleasing surface is crucial for visible products within industries like electronics or interior architecture. For instance, many smartphone housings utilize similar lightweight aesthetic considerations.
Flexibility and Formability: The temper H18 still allows for a controlled measure of flexibility, enabling manufacturers to undertake a wide variety of forming processes—bending, shaping, and wrapping—whether in creating simple containers or more complex furniture outlines.
Thermal and Electrical Conductivity: As an aluminum alloy, it possesses excellent thermal and electrical conductivity, making it suitable for applications requiring rapid heat dissipation—such as heat exchangers and conductive housings.

Applications: Casting a Wide Net

The versatile nature of the 3003 H18 0.3mm thin aluminum sheet propels its usage across various sectors.

Construction Segments and Building Applications: It often manifests in roofs, building facades, and interior wall panels. Contractors capitalize on its lightweight and non-corroding traits while optimizing transportation costs and installation time.
Automotive Components: Given the ongoing revolution in automotive safety and efficiency standards, this aluminum sheet is tapping into use for lightweight vehicles while still benefitting fundamentals like strength and resilience.
Appliance Manufacturing: Major appliance manufacturers are also choosing this aluminum variant for product assemblies ranging from washing machines to kitchen fenders with exemplary resonance between design and distraction resistance.
Home Decoration: Interior designers and architects harness the draping ability and reflective properties of this aluminum layer in modern showcase items, accentuating everything from artistic pieces to elaborate ceilings.
Electronic Enclosures: For consumer electronics, the aims would tilt towards improving lifestyles while maximizing product reversibility—again, exploiting its tightness and ability to conduct heat efficiently.
