Industry Application for Aluminum
Due to its superior mechanical properties, lightweight, recyclability, natural corrosion resistance, aluminum is widely used in diverse industries, such as consumer goods, medical, communication, automotive and aerospace industries.
Commercial Goods
Due to its low cost and light weight, aluminum is also often used in everyday consumer products, such as telescope parts, flashlight parts, e-cigs parts, etc.
Medical Devices
Aluminum alloy is also frequently used in the manufacture of precision medical component parts, such as surgical instruments, medical implants, etc.
Electronic Devices
Aluminum alloy used to make consumer electronics, such as laptops, camera cover, lighting fixtures, smartphone case, high-end audio equipment, and so on.
Aerospace
Due to its superior mechanical properties, aluminum is used in a wide range of applications in the aviation industry, such as fuselage skins, stringers, bulkheads, plane wing skins, and other parts for aircraft.
Automotive
Die-cast aluminum parts are also more common in the auto industry applications, like the front and rear covers for motors, cylinders, fluid system components, exhaust parts, oil pump housing,etc.
Telecommunication
Most of the various exposed covers, housings and enclosures used in the communication industry are also made of aluminum alloy. In addition to these, also including heat sinks, radar base plates, etc.
Surface Finish for Aluminum Parts
Th component parts made of aluminum are generally bead blasted and anodized, especially for the ones with cosmetic requirements.
Anodizing is the most common surface treatment process for aluminum, whether it is normal anodizing or hard anodizing to improve the corrosion resistance of the available aluminum alloys.
Polishing, chemical conversion coatings and metal plating can also be used on aluminum alloys to achieve diverse finishes effect.
Cost-saving Advice
Cost is often a major consideration in most designs, and not every factory has the ability to optimize cost control. With the experience our company has gained over the years, there are three main cost saving tips for the manufacturing process of precision custom aluminum parts.
- Design principles: When manufacturing aluminum parts, the priority for cost savings is to design following the principle of DFM and to avoid or limit the use of features that are difficult to machine.
- Material selection : The price of aluminum alloy materials varies depending on the grade. If only testing or prototyping is required, a different grade of another alloy material with similar properties may also be considered as a substitute.
- Principles of simplified design: If possible, consider splitting the complex design into separate parts and then connecting or assembling them by other processes. Should avoid one-piece complex structure designs unless necessary.
