Louis Metals provides Aluminium 3003 Forgings in Houston, with high formability and corrosion resistance for general applications. 3003 is a manganese-alloyed, non-heat-treatable aluminum with a broad application base in HVAC, roofing, and decorative industries. Our forgings conform to ASTM B247 and are specially cared for to deliver performance and appearance. 3003 from Louis Metals is available in custom tempers and shapes and is best for applications requiring moderate strength and superior workability.
3003 has 1.0–1.5% Manganese content. It provides tensile strength of 130–200 MPa and yield strength approximately 100–170 MPa. The alloy is not heat-treatable but can be cold worked to enhance strength. It possesses good corrosion resistance and weldability. 3003 also provides superb formability for deep drawing and forming.

Aluminum 3003 offers excellent corrosion resistance, good formability, lightweight, and high strength-to-weight ratio, making it ideal for custom forgings in industries like aerospace, automotive, and construction.
Aluminum 3003 is not ideal for high-temperature forging applications due to its low strength at elevated temperatures. It is more suitable for applications requiring good formability at moderate temperatures.
Aluminum 3003 has good workability, making it easy to forge. Its excellent formability allows for smooth shaping, but it requires careful temperature control to avoid material damage during forging.
3003 Forgings are found in roofing sheets, gutters, cooking ware, truck body parts, HVAC units, and fuel tanks. Its suitability for stamped or spun components due to its high ductility places it in siding, awnings, and cladding. 3003 is suitable for economical, lightweight components that demand a long service life and corrosion resistance.
