Advantages of Using Aluminum in Casting

Aluminium has become the material of choice for precision casting in various industries. Its unique combination of physical and mechanical properties offers unrivalled advantages in the field of component manufacturing.

Excellent Strength-to-Weight Ratio: The density of aluminium is only 1/3 that of steel, which means that up to 60% weight reduction can be achieved for the same part. Moreover, the strength of aluminum alloy can reach 80% of that of ordinary steel after heat treatment. This extreme strength-to-weight ratio is the reason why aluminum castings are so popular in areas where weight is important, such as automotive and aerospace

Efficient Molding Capabilities: The melting temperature of aluminum is about 660°C, and it can save more than 50% energy compared with steel when used for casting. At the same time, it has excellent fluidity, which can perfectly present the fine structure of parts, and can also manufacture ultra-thin wall parts with 0.5mm through die casting
Recyclability:Aluminum is a sustainable metal material. In actual industrial production, its recycling rate can reach around 90%, with extremely low energy consumption—only 5% of primary aluminum production. Additionally, the mechanical properties of recycled aluminum in die-casting/sand-casting applications show almost no degradation. In recent years, more and more companies have begun using recycled aluminum in their products, driven by cost savings and environmental considerations.

FAQ

Find answers for common questions about custom aluminum castings from HDC.

What is cast aluminum?

The composition of cast aluminum alloys is specially designed for the casting process, usually with a higher proportion of silicon to improve the fluidity of molten aluminum and reduce the solidification retraction rate. Common cast alloy series such as: A3xx (e.g. A356/A357 - Al-Si-Mg series), A4xx (e.g. A413 - Al-Si series). It may also contain higher levels of elements such as copper, magnesium, zinc, etc., to achieve specific properties.

Can HDC manufacture molds for casting?

Yes, we have 3-axis and 4-axis CNC machines, as well as professional model design and manufacturing personnel, allowing us to manufacture molds used in various casting processes independently.

What's the typical lead time?

It depends on the casting process and quantity. For a sand casting prototype, the typical lead time is 7 - 15 days. For a large quantity of die acting or permanent mold casting parts, the leads may ranging from 2 months to 4 months.

Do I need to pay for the mold?

Yes, the mold fee is needed. However, if the order meets our requirements, the mold fee can be refunded.

Does HDC offers after sales service?

Yes, quality is our uncompromising goal, and we are responsible for all quality issues caused by material and processing technology.

How do I pay for the order?

We provide T/T, L/C, D/P, and PayPal as payment methods. When placing an order, you need to pay a deposit first, usually 30% of the total payment, and the rest is paid after the production is completed, before shipping.
