Mechanical Properties
- Strength: 3103 aluminum alloy generally has slightly higher strength than 3003 due to its higher manganese content, which increases tensile strength and hardness.
- Ductility: 3003 aluminum alloy offers higher ductility, making it better suited for applications requiring complex forming processes, such as deep drawing and spinning.
- Hardness: 3103 has slightly higher hardness than 3003, making it more suitable for applications needing greater strength and hardness, such as certain pressure vessels and high-pressure piping.
Corrosion Resistance
Both alloys have excellent corrosion resistance, especially in humid environments or atmospheric conditions. Their corrosion resistance is largely similar, though 3103 may perform slightly better in certain corrosive environments due to its slightly higher manganese content.
Weldability
3003 and 3103 aluminum alloys both offer good weldability and are typically joined using MIG or TIG welding. There is no significant difference in weldability between the two, making them suitable for the same types of welding applications.
Primary Applications
