What Types of Components Are Commonly Produced Using Aluminum Casting?
Aluminum casting is widely used across industries because it supports lightweight structures, complex geometries, and strong mechanical performance. As a China manufacturer specializing in custom aluminum castings, we produce housings, structural brackets, heat sinks, pump and valve bodies, motor components, and instrument enclosures used in agricultural machinery, automotive systems, bicycles, marine equipment, LED work lights, medical devices, gas meters, water heaters, and many other fields. The versatility of the casting process allows us to meet both high-volume industrial demands and specialized custom product requirements.
How Do I Choose Between High-Pressure Die Casting, Low-Pressure Die Casting, Gravity Casting, and Investment Casting?
Each casting process is suitable for different structures and performance needs, and our engineering team helps customers select the best option during the early design stage. High-pressure die casting is ideal for thin-wall, complex components produced in large quantities, while low-pressure die casting provides better metal flow control and improved strength for medium-wall parts. Gravity casting offers stable performance with thicker walls and higher load demands, and investment casting enables high-precision details for small or intricate components. As a custom casting manufacturer in China, we evaluate cost, strength, and functional requirements to ensure the most efficient solution.
Can Aluminum Castings Be Heat Treated or Welded?
Yes, many aluminum castings produced through gravity casting, low-pressure casting, sand casting, and investment casting can undergo T5 or T6 heat treatment to achieve higher strength and improved mechanical properties. These processes also typically produce structures that are weldable and suitable for secondary assembly. High-pressure die castings may have more limitations due to porosity, but our vacuum-assisted HPDC solutions help reduce internal defects and increase weldability. We guide every customer to the most suitable combination of alloy, heat treatment, and casting process for their custom part.
What Mechanical Properties Can Be Achieved with Aluminum Castings?
Mechanical properties depend on alloy type, casting method, and heat treatment. As an experienced aluminum casting manufacturer, we commonly achieve tensile strengths between 180–320 MPa, yield strengths of 120–260 MPa, elongation levels from 2–10%, and hardness values around 60–100 HB. Processes such as low-pressure casting and gravity casting often produce denser, more reliable structures suitable for high-load, high-vibration, or sealing-critical applications used in automotive, energy, and industrial equipment.
What Aluminum Alloys Are Commonly Used?
We work with a full selection of aluminum alloys, including A356, AlSi7Mg, AlSi10Mg, AlSi9Cu3, AlSi12, and other industry-standard formulations. These alloys each offer distinct advantages in terms of strength, fluidity, corrosion resistance, and machinability. For custom aluminum castings, our engineers analyze customer specifications, working environments, temperature requirements, and expected lifespan to recommend the most suitable material for the product.
What Surface Treatments Are Available?
To meet the diverse needs of global customers, we provide a wide range of finishing options that enhance durability, appearance, and corrosion resistance. Common treatments include sand or shot blasting, anodizing, powder coating, painting, and chromate conversion coating. For sealing surfaces or components that require high precision, CNC machining can achieve extremely fine finishes suitable for mechanical assembly or functional contact areas. These finishing capabilities help ensure our China manufacturing services meet the quality standards of industries such as energy, automotive, LED lighting, and marine equipment.
What Dimensional Accuracy Can Be Achieved?
Dimensional accuracy varies depending on the manufacturing method, and our custom casting and CNC machining capabilities allow us to achieve extremely tight tolerances where needed. High-pressure die casting provides very consistent as-cast accuracy, while gravity casting and low-pressure casting can achieve even tighter precision after machining. For critical components, CNC finishing enables tolerances as fine as ±0.01 mm, supported by CMM inspection to ensure that every product meets the customer’s specifications.
How Do You Control Porosity in Aluminum Castings?
As a professional casting manufacturer, we use multiple techniques to minimize porosity, including controlled melt treatment, degassing, ceramic filtration, optimized mold flow simulation, and vacuum-assisted casting technology. For products requiring extremely high density, such as sealing housings, energy components, gas meter parts, or automotive structural pieces, we often recommend gravity casting or low-pressure casting due to their stable solidification characteristics. X-ray inspection or CT analysis can also be provided for projects that require rigorous quality assurance.
How Do You Ensure Leak-Tight Performance for Components That Must Maintain Pressure or Fluid Sealing?
Leak-tight performance is achieved through a combination of dense casting structures, optimized mold design, and precision machining of sealing surfaces. Our low-pressure and gravity casting processes naturally reduce air entrapment, creating castings suitable for pumps, hydraulic systems, cooling plates, and gas meter bodies. When necessary, we apply advanced machining and surface treatments to ensure reliable sealing. This engineering approach allows us to deliver custom castings that meet demanding leak-proof requirements across multiple industries.
What Leak Testing Methods Are Used Before Delivery?
Leak testing depends on the application, but typically includes air-under-water tests, pressure decay measurements, water pressure simulation, or high-sensitivity helium leak detection. Each test method ensures that the castings perform reliably under real-world conditions, whether they are used in automotive systems, water heating equipment, energy devices, or precision instruments. All tests are performed according to customer specifications and international standards.
