Aluminium Casting Alloys
Aluminum casting alloys are materials used for the production of various cast components through processes such as sand casting, die casting, or investment casting. These alloys are designed to be suitable for casting methods, offering specific characteristics and properties that make them well-suited for different applications.
A356:
➤Properties:A356 is a heat-treatable Aluminium alloy with good castability, high strength, and excellent corrosion resistance. It is often used in automotive components, aircraft parts, and general engineering applications.
A380:
➤Properties:A380 is a versatile and widely used Aluminium alloy in die casting. It exhibits good fluidity, high strength, and excellent corrosion resistance. A380 is commonly used for components in the automotive industry, household appliances, and electronic enclosures.
A383:
➤Properties:A383 is a pressure die-casting alloy known for its excellent fluidity and resistance to hot cracking. It is often used in automotive applications, especially for components requiring high strength and durability.
A413:
➤Properties:A413 is a gravity-casting alloy with good corrosion resistance and pressure tightness. It is commonly used in applications where a combination of strength and corrosion resistance is required, such as in marine components.
Aluminum-Silicon Alloys:
➤Properties:Alloys with high silicon content, such as the 3xx series (e.g., 319, 356), are popular for their excellent castability and high fluidity. These alloys are used in a variety of applications, including engine components, pump housings, and decorative parts.
Aluminum-Copper Alloys (2xx Series):
➤Properties:Alloys like 202, 206, and 212 are part of the 2xx series and contain copper as a major alloying element. These alloys offer good strength and wear resistance and are used in applications such as marine components, pump parts, and valve bodies.
Aluminum-Zinc Alloys (7xx Series):
➤Properties:Alloys like 713, 771, and 774 belong to the 7xx series and contain zinc as a major alloying element. These alloys are used in both sand and permanent mold casting for applications requiring high strength and hardness.
| Alloy: Aluminum casting alloys encompass a range of alloys suitable for casting processes. Common casting alloys include A356, 356, and 380, each with its own characteristics suitable for various applications. |
| Temper: Unlike other Aluminium products, casting alloys are typically discussed in terms of their as-cast condition rather than specific tempers. The temper is influenced by the cooling rate and other casting conditions. |
| Thickness: The thickness of Aluminium castings is variable and depends on the design and application. Castings can be produced with varying thicknesses to meet specific requirements. |
| Width: In the context of Aluminium casting alloys, the concept of width may not be as relevant as it is in products like sheets or plates. Instead, focus is on the dimensions and geometry of the cast component. |
| Pattern: The pattern refers to the mold or die used in the casting process. Casting alloys take the shape of the mold, allowing for a wide variety of complex and intricate designs. |
| Standard: Compliance with industry standards is important for ensuring the quality and performance of Aluminium casting alloys. Standards can be set by organizations such as ASTM or other relevant bodies. |
| Surface Treatment: While some castings may receive secondary treatments for improved properties, many casting alloys are used in their as-cast condition, taking advantage of the surface finish directly from the mold. |
| PVC Coated: PVC coating is not a common feature for Aluminium casting alloys. The focus is more on the characteristics achieved during the casting process. |
| MOQ (Minimum Order Quantity): Manufacturers may specify a minimum order quantity for Aluminium castings, depending on the complexity of the casting and production processes. |
| Packing: Details on how the Aluminium castings are packed for shipping, including information on packaging materials and methods to ensure safe transport. |
| Port of Dispatch: Specifies the port from which the Aluminium castings will be dispatched. This is crucial for logistics and shipping coordination. |
| Delivery Time: The estimated time it takes for the Aluminium castings to be delivered from the time of order placement. Delivery time can be influenced by factors such as production time, curing, and cooling processes. |
| Payment: Information on accepted payment methods and terms for Aluminium casting orders. This may include details on advance payments, letters of credit, or other financial arrangements. TT / LC / TT+LC |
Aluminum-Magnesium Alloys (5xx Series):
➤Properties:Alloys such as 514, 518, and 520 contain magnesium as a primary alloying element. These alloys offer good strength, weldability, and corrosion resistance. They are used in various casting applications, including marine components and structural parts.
Aluminum-Lithium Alloys:
➤Properties:These alloys, which include lithium as an alloying element, are known for their low density and high specific strength. They are used in aerospace applications where weight reduction is crucial.
