3004 Aluminum Sheet Description:
The main alloying additive of 3004 aluminum alloy is manganese. Alloy 3004 has moderate strength, good machinability and good corrosion resistance. It is usually rolled and extruded, but usually not forged and not used for casting.
It can be cold worked (but unlike other types of aluminum alloys, which require heat treatment) to produce a temper with higher strength but lower ductility.
Like most other aluminum-manganese alloys, 3003 is a general-purpose alloy with moderate strength, good machinability, and good corrosion resistance. It is usually rolled and extruded, but not usually forged.

Advantages of 3004 aluminum metal
It is stronger than 3003 aluminum plate. It is usually rolled and extruded, but not usually forged.
The chemical composition of 3004 is very similar to that of 3003. The addition of magnesium makes it close to 5052 in strength, with good corrosion resistance and good formability. These properties make 3004 a good candidate for storage tanks, pressure vessels and cookware.
The properties of 3004 aluminum sheet are characterized by good formability, solubility resistance, corrosion resistance, etc. Usually used to produce some parts with much higher strength requirements than 3003.
- High plasticity. 3004 aluminum plate has high plasticity in the annealed state, good semi-cold hardening plasticity, and low cold hardening plasticity.
- Finish off well. It can adapt to the maximum speed that most machine tools can achieve for milling, boring, planing and other machining operations. In addition, 3004 aluminum plate has good weldability, but poor machinability.
- Slightly higher strength. With the addition of alloy component Mn, while maintaining the excellent machinability and corrosion resistance of pure aluminum, the strength of 3004 aluminum plate increases slightly, which is higher than that of 3003 aluminum plate and 10% higher than that of 1100 series.
- Good anodization. 3004 aluminum plate anodized surface treatment effect is amazing, it is a good choice for color-coated aluminum substrate. The surface of the anodized 3004 aluminum plate has enhanced corrosion resistance and can also show colorful colors.

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. |
Applications | Commonly used in the manufacture of storage tanks. Is commonly used in sheet metal work. |
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. See “Annealing”. |
Forging | Forging may be accomplished in the range of 950 to 700 F. |
Hot Working | AL 3004 can be hot worked at temperatures of 900 to 500 F. |
Cold Working | Cold working capability of this alloy is good. it can readily be cold worked up to a 75% reduction of area by conventional methods. Working beyond the 75% reduction requires an intermediate anneal. |
Annealing | Anneal at 650 F and air cool. |
Aging | Not applicable to this alloy. |
Tempering | Not applicable. |
Hardening/hardness | Cold working is the only means of producing the harder (H) tempers of this alloy. |
Other Physical Props | Electrical conductivity 39% of copper. |
Other Mechanical Props | Shear strength for O temper is 16 ksi. H32 temper, 17 ksi and for H38 temper 21 ksi. |
