3104 Aluminum vs. 3104-H19 Aluminum

Jan. 02, 2025

3104 aluminum alloy and 3104-H19 aluminum alloy belong to the same series of aluminum alloys. They share many similar properties but also differ in certain aspects.

3104 aluminum alloy: It has good ductility and formability, making it suitable for applications that require high formability but not particularly high strength.
3104-H19 aluminum alloy: It has been heat-treated to increase its strength, making it suitable for applications requiring higher strength and fatigue resistance, although it sacrifices some ductility.

The choice of which aluminum alloy to use depends on specific application needs. If higher strength and fatigue resistance are required, 3104-H19 aluminum alloy would be a better choice; if better ductility and formability are needed, 3104 aluminum alloy may be more appropriate.

Tensile Strength and Yield Strength of 3104 vs 3104-H19 Aluminum Alloys

3104 Aluminum Alloy: It has relatively low tensile strength and yield strength, but it offers good ductility and formability, making it suitable for applications requiring a certain degree of flexibility.
3104-H19 Aluminum Alloy: Compared to 3104 aluminum, 3104-H19 has higher tensile strength and yield strength, meaning it is stronger and more resistant to deformation under load. The H19 temper is a high-strength variant of 3104 aluminum, achieved through specific heat treatment to provide higher strength and better load-bearing capacity.

Ductility and Elongation at Break of 3104 vs 3104-H19 Aluminum Alloys

3104 Aluminum Alloy: It has good ductility and formability, particularly suitable for processing complex shapes. Its elongation at break is relatively high, meaning it can undergo more deformation during stretching without easily breaking.
3104-H19 Aluminum Alloy: It has lower elongation at break, indicating that its ductility is relatively poor. For applications requiring high ductility, 3104-H19 may not be as suitable as 3104 aluminum alloy. Although it has higher strength, its ductility is somewhat sacrificed.

Fatigue Strength of 3104 vs 3104-H19 Aluminum Alloys

3104 Aluminum Alloy: Fatigue strength is relatively low compared to the two, making it suitable for small dynamic loads.
3104-H19 Aluminum Alloy: It has slightly improved fatigue strength. The high-strength H19 variant is better suited for applications involving long-term loads or repeated loading. This makes it ideal for certain industrial applications, such as high-strength structural components, providing a longer service life.

Thermal Performance, Electrical Properties, and Shear Strength: There is almost no difference between the two in these aspects. Whether it is 3104 or 3104-H19, their thermal conductivity, electrical conductivity, and shear strength are very similar, making them suitable for a wide range of standard industrial applications.

Applications of 3104 vs 3104-H19 Aluminum Alloys

3104 Aluminum Alloy: Due to its higher ductility and lower strength, 3104 aluminum is commonly used for deep-drawn parts, such as cans, containers, and food packaging. It can also be used for applications that require high formability but do not demand extreme strength.
3104-H19 Aluminum Alloy: Its high strength makes it suitable for structural applications that bear larger loads. It is commonly used for components requiring strength, durability, and fatigue resistance, such as certain structural parts, industrial equipment, and pressure vessels.
