Alloy Geek 3003 Aluminum Standard
Aluminum alloy 3003 is a commercially pure aluminum alloy that belongs to the 3xxx series of aluminum alloys. It is alloyed primarily with manganese, making it non-heat-treatable and known for its good formability, corrosion resistance, and moderate strength. This alloy is often used for applications that require these specific properties.
- Silicon (Si): 0.60% max
- Iron (Fe): 0.70% max
- Copper (Cu): 0.05% - 0.20%
- Manganese (Mn): 1.0% - 1.5%
- Zinc (Zn): 0.10% max
- Others (each): 0.05% max
- Others (total): 0.15% max
- Aluminum (Al): Remainder
- Formability: Alloy 3003 has excellent formability, making it suitable for a variety of shaping and bending processes.
- Corrosion Resistance: It offers good corrosion resistance, making it suitable for applications exposed to outdoor and marine environments.
- Strength: While not as strong as some other aluminum alloys, alloy 3003 has moderate strength and is suitable for applications that don't require high strength.
- Weldability: It is weldable using common methods like resistance welding and gas welding.
- Applications: Alloy 3003 is commonly used for applications such as cooking utensils, food and chemical handling equipment, storage tanks, roofing and siding materials, and other general sheet metal applications.
Because of its non-heat-treatable nature, the properties of alloy 3003 are primarily influenced by cold working, annealing, and the manufacturing processes it undergoes.
XRF Samples are thinner samples approximately 1/4 inch thick. OES Standards are thicker in nature and are approximately 1 inch thick. Please Contact Us if you would like to know the specific dimensions of a sample.
Reference Material (RM): A reference material, or RM, is a material with a known composition or property that is used for informational purposes to look at analytical instruments, methods, or procedures. It serves as a point of comparison to ensure the accuracy and reliability of measurements. Reference materials can vary in terms of their level of characterization and traceability. Some reference materials may have well-defined properties, but they might not have undergone the rigorous testing and certification process that certified reference materials (CRMs) undergo. Reference Material chemical compositions are for information purposes.
Certified Reference Material (CRM): A certified reference material, or CRM, is a type of reference material that has been thoroughly analyzed and characterized using multiple validated methods to determine its composition or properties. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 (ISO 17034). The certification process includes interlaboratory comparison and statistical analysis to ensure accuracy and traceability.
In summary, the main difference between a reference material and a certified reference material lies in the level of characterization, validation, and certification. CRMs have undergone a more comprehensive and rigorous testing process, resulting in certified values and uncertainties that can be confidently used for instrument calibration, quality control, and research. Reference materials, on the other hand, can provide a point of comparison but do not have the same level of certification and traceability as CRMs. When accuracy and traceability are critical, certified reference materials are preferred.
