The 3003-H14 temper refers to 3003 aluminum alloy supplied by GNEE, which contains manganese as its primary alloying element to improve strength. In the H14 condition, the alloy is strain-hardened and then partially annealed to a half-hard temper, offering higher strength and hardness than fully annealed (O temper) aluminum while still maintaining excellent formability. This balance makes it especially suitable for bending, deep drawing, and general sheet-metal fabrication without cracking.
In aluminum alloys, the term "temper" describes the specific mechanical and physical characteristics the material develops through controlled heating, cooling, or mechanical processing. Temper designations are typically made up of a letter and a number, providing clear insight into the alloy's final properties.
For GNEE 3003 aluminum, the H14 temper indicates that the alloy has been strengthened through strain hardening (cold working). This process shapes the aluminum at room temperature, increasing its strength and hardness without the use of heat treatment. The number "14" identifies the degree of hardening, with higher numbers representing greater strength and hardness levels.
The H14 temper offers an effective balance of strength and flexibility, making it suitable for a wide range of applications. By understanding temper designations, engineers and fabricators can choose the most appropriate aluminum materials from GNEE, ensuring reliable performance and successful project outcomes.
Explanation of the Designation
3003: Identifies the aluminum alloy, which typically contains about 1.2% manganese, providing improved strength compared with commercially pure aluminum.
H: Indicates a strain-hardened temper, where strength is increased through cold working.
14: Specifies the degree of strain hardening. The "4" in H14 denotes a half-hard condition, delivering roughly half the tensile strength of fully hard (H18) material.
Key Features
Excellent Formability: Can be easily bent, drawn, and shaped into complex forms.
Moderate Strength: Stronger than annealed aluminum, yet more workable than fully hardened tempers.
Outstanding Corrosion Resistance: Suitable for outdoor environments and chemical exposure.
Good Weldability: Can be readily joined using standard welding techniques.
Typical Applications
Sheet-metal fabrication such as panels and ducting
Food and beverage packaging, including cans and closures
Radiators, storage tanks, and general industrial equipment
Tread (diamond) plate applications where slip resistance is required
