3004 Aluminum Coil
Haomei Aluminum supplies 3004 aluminum coil for forming, coating and general fabrication applications that require higher strength than 3003 alloy while maintaining good workability and resistance to atmospheric corrosion. Coils can be supplied in O, H14, H24, H34, H38 and selected application-specific tempers.
What is 3004 Aluminum Coil?
3004 is an aluminum-manganese-magnesium alloy in the 3xxx series. It is generally classified as a non-heat-treatable alloy, which means its strength is developed mainly through cold working rather than precipitation heat treatment.
Compared with 3003 aluminum coil in comparable tempers, 3004 generally offers a higher strength level because of its magnesium addition. The material still provides useful formability, weldability and resistance to many common atmospheric service environments.
Final material selection should be confirmed according to the applicable standard, thickness, temper, processing method and end-use environment. Material properties can vary by temper, gauge and mill production route.

Choosing the Right Temper: O, H14, H24, H34, H38 and H19
Temper selection is one of the most important parts of specifying 3004 aluminum coil. The right temper is determined by the required strength, bend radius, draw depth, forming process, surface treatment and final product function.
3004-O Aluminum Coil
O temper is fully annealed and relatively soft. It is normally considered for deep drawing, bending and forming operations where maximum ductility is more important than final hardness.
3004-H14 Aluminum Coil
H14 is a strain-hardened temper that offers more strength than annealed material while retaining workable forming characteristics for selected fabrication processes.
3004-H24 Aluminum Coil
H24 material is strain-hardened and partially annealed. It can provide a practical balance between strength and formability for many fabricated sheet applications.
3004-H34 Aluminum Coil
H34 is a more highly strain-hardened and stabilized temper than H24. It may be selected for applications requiring improved rigidity while still allowing controlled forming.
3004-H38 Aluminum Coil
H38 is a hard temper with higher strength and reduced ductility compared with O, H14 or H24. It is better suited to applications where severe forming is not required.
3004-H19 Aluminum Coil
H19 is a high-strength temper used for specific applications. Requirements for H19 material must be carefully confirmed because thickness, forming process, mechanical properties and industry standards can be highly application dependent.
Features of 3004 Aluminum Coil
Higher Strength Than 3003
3004 is commonly considered when a fabricated part requires more strength than standard 3003 alloy can provide under comparable conditions.
Cold-Work Strengthening
The alloy is strengthened through rolling and other cold-working processes. Annealing can be used when additional ductility is required.
Formability and Fabrication
Depending on temper, 3004 coil can be suitable for bending, drawing, roll forming, stamping and general sheet-metal fabrication.
Corrosion Resistance
Like other aluminum alloys, 3004 forms a natural oxide film that helps provide resistance to atmospheric corrosion in many normal service conditions.
3004 Aluminum Coil Surface Finishes and Processing Options
Surface finish should be selected according to the end use, forming method, coating process, visual requirement and corrosion environment. Not every finish is suitable for every thickness, temper or application.
Mill Finish 3004 Aluminum Coil
Mill finish coil is supplied with the natural rolled aluminum surface. It is commonly used where the customer will further process, coat, laminate, stamp or fabricate the material.
Color-Coated 3004 Aluminum Coil
For applicable building, decorative or industrial uses, 3004 may be supplied with a polyester, SMP, HDP or PVDF coating system, subject to technical confirmation of alloy, gauge, pretreatment and final-use conditions.
Embossed or Stucco-Embossed Options
Embossed surfaces may improve appearance, stiffness or slip resistance in certain applications. Confirm the required pattern, thickness, coil width and surface standard before ordering.
Protective Film
PE or PVC protective film may be available for selected surface-sensitive products. Film type, adhesion level and removal conditions should be confirmed according to the customer’s fabrication process.

3004 Aluminum Coil More Informations
| Property | Description |
| Principal Design Features | This is an alloy of aluminum with magnesium and manganese. It is strengthened (hardened) by cold work only as it does not respond to heat treatment, other than annealing. |
| Machinability | The machinability of this alloy is considered to be excellent, especially in the hard temper. As is typical of the aluminum alloys an oil lubricant should be used for machining, although light cuts may be done dry. |
| Forming | AL 3004 is easily formed by either cold or hot working with conventional tooling. |
| Welding | The alloy is weldable by the standard methods. Best results are obtained by use of TIG or MIG welding with the same alloy as filler rod. |
| Heat Treatment | Heat treatment has no effect upon this alloy. It may be annealed after cold working however. |
