What Does 3003 H16 Mean?
3003 H16 refers to Aluminum Alloy 3003H16 temper, indicating a work-hardened aluminum alloy strengthened by manganese. The material is cold-rolled to approximately three-quarters of full hardness (H18). It is commonly supplied in and is widely used in roofing systems, heat exchangers, and decorative panels.
Aluminum Alloy 3003
1.0–1.5% manganese, which improves tensile strength and corrosion resistance compared with commercially pure aluminum.
Non-heat treatable, but strengthened through cold working
3003-H16 Alloy Young's Modulus
The Young's Modulus of 3003-H16 Alloy is 70,000 MPa.
3003-H16 Alloy Ultimate Strength
The Ultimate Strength of 3003-H16 Alloy is 165 MPa.
3003-H16 Alloy Yield Strength
The Yield Strength of 3003-H16 Alloy is 145 MPa.
H16 Temper Explained
H16 indicates that the aluminum has been strain-hardened (cold-worked) to a specific strength level.
The first digit "1" confirms cold working
The second digit, "6," signifies approximately 75% of full hard temper (H18)
greater strength and hardness than H12 or H14softer and more formable than H18.
Compared with annealed (O) or lightly work-hardened tempers, H16 provides , with a corresponding reduction in ductility.
3003 H16 that combines strength, corrosion resistance, and workable formability. GNEE supplies 3003 H16 aluminum primarily as , making it an excellent choice for applications that require improved strength without significantly compromising malleability.
