Chuck Metals is a trusted manufacturer and supplier of Aluminium 3003 Forgings right here in Singapore, catering to a variety of industries across Pulau Ujong and its neighboring areas. Aluminium 3003 is a non-heat-treatable alloy that’s primarily mixed with manganese, and it’s well-regarded for its impressive corrosion resistance, good formability, and moderate strength. This alloy finds its way into architectural, industrial, and food-grade applications where durability and ease of fabrication are key. At Chuck Metals, we take pride in producing top-notch 3003 forgings that meet ASTM B247 standards, ensuring they have consistent dimensions, a fine surface finish, and long-lasting performance even in tough environments.
Typically, Aluminium 3003 Forgings contain about 1.0–1.5% manganese, which enhances their strength compared to pure aluminum grades. They boast a tensile strength ranging from 140 to 200 MPa and a yield strength of around 125 MPa. While this alloy can’t be strengthened through heat treatment, it responds well to cold working. It’s also known for its excellent weldability, non-magnetic properties, and resistance to both atmospheric and chemical corrosion, making it a go-to choice for settings where moisture or mild chemicals are present.

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.
You’ll find Aluminium 3003 Forgings in a wide array of applications, including roofing sheets, gutter components, storage tanks, kitchen equipment, and decorative trim. They’re also perfect for chemical handling systems, transportation panels, insulation jacketing, and HVAC ducting, where their corrosion resistance and workability really shine. With a great balance of strength, formability, and durability, Aluminium 3003 is particularly well-suited for both indoor and outdoor uses in the construction, automotive, marine, and food processing sectors.
