What is 3003 aluminum alloy

3003 aluminum alloy is a kind of wrought AL-MN alloy, and it is also a representative product of 3000 series aluminum alloy;

3003 aluminum alloy is a non-heat-treatable aluminum alloy and it can be cold-worked to obtain a tempered state with higher strength but lower ductility;

3003 Aluminum Alloy

Aluminum alloy 3003 is usually obtained by rolling. As a wrought alloy, it cannot be cast and is often used in sheet metal applications such as gutters, downspouts, roofing, and siding.

3003 aluminum price

3003 aluminum is a perfect combination of weight and hardness in terms of performance. In fact, there is another reason why 3003 aluminum can be used in many industries;

The perfect combination of performance and price can also be used to describe 3003 aluminum;

The price of 3003 aluminum is slightly higher than that of 1000 series aluminum alloys (150/1060/1100) but much lower than that of 5000 series aluminum alloys. Therefore, 3003 aluminum has a high cost performance and is widely used in the market;

Factors affecting the price of 3003 aluminum:

• Aluminum ingot price (raw material)
• Processing cost
• Exchange rate
• Packing and Shipping Fees

3003 aluminum vs 6061

The biggest difference between 3003 aluminum and 6061 aluminum is that 3003 aluminum cannot be heat treated, while 6061 can be strengthened by heat treatment;
There is also a big difference between the two in terms of performance. We take 6061-T6 and 3003-H18 as examples for comparison;

Machinability	Good		Fair

Price comparison 3003 aluminum vs 6061

3003 aluminum alloy yield strength, shear strength, hardness, machinability, etc. are not as convenient as 6061 aluminum, but 3003 aluminum alloy has its own advantages, that is the price. The price of 3003 aluminum is much lower than that of 6061, so the application of 3003 aluminum is more for extensive.
