Description
Alloy Geek 319 Cast Aluminum Standard
Aluminum alloy 319 is a specific type of aluminum alloy. It falls under the aluminum-silicon (Al-Si) alloy category. Alloys in this category are known for their good castability, heat resistance, and relatively high strength-to-weight ratio. Aluminum alloy 319 is primarily used in the casting process to create various components and parts.
Composition:
- Aluminum (Al): Approximately 85.7% - 91.3%
- Silicon (Si): Approximately 5.5% - 6.5%
- Copper (Cu): Approximately 3.0% - 4.0%
- Magnesium (Mg): Approximately 0.3% - 0.5%
- Iron (Fe): Maximum of 1.0%
- Other Trace Elements: These can include elements like manganese (Mn), zinc (Zn), and titanium (Ti), each typically present in small percentages.
Key Properties:
- Composition: Aluminum alloy 319 typically contains a significant amount of silicon (Si), which contributes to its casting properties and heat resistance. Other elements such as copper (Cu) and magnesium (Mg) might also be present in smaller amounts.
- Castability: Alloy 319 has good castability, making it suitable for intricate and complex shapes. It is often used in applications where casting precision is important.
- Heat Resistance: The silicon content in alloy 319 imparts heat resistance to the alloy. This can be particularly useful in applications where the component may be exposed to elevated temperatures.
- Strength: While not as strong as some other aluminum alloys, 319 still offers a reasonable balance between strength and weight, making it suitable for various load-bearing applications.
- Corrosion Resistance: Aluminum alloys, in general, possess good corrosion resistance due to the formation of a protective oxide layer on their surface. The exact level of corrosion resistance can depend on the specific alloy composition and environmental conditions.
- Applications: Aluminum alloy 319 is commonly used in the automotive and machinery industries for producing components like engine blocks, cylinder heads, and other parts that require good castability, heat resistance, and moderate strength.
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.
