3003 H14 Aluminum Coil

3003 H14 Aluminum Coil Overview

3003 h14 aluminum coil refers to h14 tempered 3003 aluminum coil. Among them, 3003 is the aluminium alloy product number named by the AA Aluminium Association. h stands for cold work hardening. And H14 tempering usually means getting 1/2 the strength with the hardness.

3003 is the most widely used aluminium alloy. It is basically commercial pure aluminum plus manganese, and its strength is about 20% higher than that of 1100 grade.

So it has all the good features of 1100 and higher strength. It has excellent corrosion resistance. It has excellent machinability and can be deep drawn or spun, welded, or brazed.

Alloy parameters of 3003 H14 aluminum coil

The alloy composition of 3003 aluminium is:^[alloy]

• Aluminium: 96.8 to 99%
• Copper: 0.05 to 0.20%
• Iron: 0.7% max
• Manganese: 1.0 to 1.5%
• Silicon: 0.6% max
• Zinc: 0.1% max
• Residuals: 0.15% max

Characteristics of 3003 h14 aluminium coil

It is not heat treatable, so it must be strengthened by cold working alone, but it can be forged at high temperatures from 500 to 950 degrees Fahrenheit.

Aluminium is easy to hot work when heat is used in this range. However, cold working is easy and can be done using traditional methods.

When annealing the alloy during or after cold working techniques, it should be done at 775 degrees Fahrenheit. This will give it enough time to heat the air thoroughly before it cools. The only way to harden this alloy is by cold working.

Performance

1. Excellent anti-rust performance.

2. Excellent forming processing characteristics, high corrosion resistance, good weldability and electrical conductivity, and the strength is higher than 1100.

3. The surface is smooth, plastic and pressure resistant;

4. The power battery shell is the first choice plate, which is impact-resistant, not easy to crack and leak, and meets the strength and stiffness requirements of the power battery shell.

Application of 3003 H14 Aluminum Coil

• In building products, for example, this alloy is used in roofs, siding, acoustic ceilings and corrugated panels.
• In the chemical and food industries, such as cooking and kitchen equipment, food equipment.
• Used in metalworking equipment for storage tanks, piping, jacketing, HVAC and aluminium plumbing.
• Some typical applications include heat exchangers, air conditioner evaporators, automotive radiators, and refrigerator liners.

Why use 3003 aluminum coil as battery case material ?

1. Good deep drawing performance. The power battery shell has been punched many times, and the deformation is large. 3003 aluminium coil has good stamping performance and stable mechanical properties.
2. Sufficient strength and hardness. In order to effectively protect the internal structure of the battery, the battery shell material needs to have sufficient strength and hardness on the premise of ensuring high plasticity.
3. Good corrosion resistance and chemical stability. 3003 aluminium coil is a typical anti-rust aluminum coil, which can adapt to different environments, has good corrosion resistance, and has a long service life as a battery shell material.

For the consideration of light weight and processability, it is an inevitable choice to use 3003 aluminum coil to make the battery case.
