What is Alloy 3003 H14?
3003 aluminium alloy is a commercially pure aluminium with high mechanical qualities and is frequently used in industries. It is a medium-strength alloy with excellent resistance to air corrosion. The alloy has superior mechanical qualities when compared to 1000 series alloys and is 20% stronger than 1100.
H14: Strain-hardened, 1/2 hard.

What is the difference between 3003 H14 and 5052?
3003 H14 has an ultimate tensile strength range of 20–26 KSI, a yield of 21, an elongation of 8.3%, and a Brinell hardness of 40, while 5052 H32 has an ultimate tensile strength range of 31–38 KSI, a yield of 28, an elongation of 12%, and a Brinell hardness of 60.
Can you weld 3003 aluminum to 6061?
3003 aluminum is easily welded using traditional procedures. Filler rods are commonly made of aluminum 1100. When welding 3003 to other aluminum alloys such as 5052, 6061, or 6062, use a 4043 aluminum filler rod.
Advantages of 3003 Aluminum Sheet
1. Excellent rust-proof property.
2. Excellent plasticity, corrosion resistance, weldability, and conductivity.
3. Better strength than 1100 aluminum alloy.
4. Ideal choice for a power battery shell because of impact resistance; it is not easy to break or leak.
