Application of Machined Aluminum Parts
Aluminum parts are used in various industries, and among all metal parts, aluminum has the most advantages in processing cost and material costs.
Automobile aluminum parts: engine parts, car body.
Sports bike: anti-vibration parts, hand brake, frame.
Mechanical equipment parts: bearings, main body.
Consumer Electronics: electronic enclosures, covers, heat dissipation enclosure
Aluminum Parts Machining Cost
Aluminum parts have the least loss of tools and equipment, and the processing speed is the fastest among all metals.
The cost composition of aluminum parts: material cost + processing cost. Average hours per hour for Aluminum CNC Machining in Tirapid are:
3-axis CNC machining: $20~40/hour.
4-axis CNC machining: $30~50/hour.
5-axis CNC machining: $40~100/hour.
Lathe processing: $30~60/hour.
The above is for reference only. Factors such as the complexity of the part, the cost of the materials, and the setup costs of the mechanic all affect the total cost.
How are high-quality aluminum parts manufactured?
Process 1: Expert team review drawings
Strictly check whether each dimensional tolerance can be met. Whether there are enough detection tools. Calculate the size of the raw material. Determine whether the fixture meets the production requirements of this project.
Process 2: Purchasing team procures tools and raw materials
Purchasing engineers place purchase orders for materials and measuring tools.
Process 3: The expert team writes the processing program
The expert team writes the processing program according to the customer’s 3D or PDF drawing.
Process 4: The mechanical engineer debugs the first product
The mechanical engineer debugs the equipment and conducts on-site inspections. After passing the test, it will be handed over to the quality engineer for inspection.
Process 5: Quality inspection of the first product
Repeat the inspection by the quality engineer, and notify the production of small batch production after judging that it is qualified.
Process 6: Low batch production by production workers
The production staff will carry out low-volume or high-volume production according to the requirements of the first sample. During the process, every 10 products are sampled for all sizes.
Process 7: Quality inspection (full inspection or sampling inspection) full inspection or sampling inspection
Sampling inspection or full inspection by quality engineers, full inspection for less than 20 pieces. Make test report. Reviewed by quality supervisor.
Process 8: Deburring deburring
Carry out the treatment of surface burrs and burrs, and clean the oil stains on the surface.
Process 9: Surface Finishing (optional) Optional
According to the surface requirements of the parts, Tirapid matches the best surface treatment factory for processing. All surfaces are provided with a surface treatment inspection report.
Process 10: Safe and reliable packaging
With many years of packaging experience, I customized packaging for parts of different shapes.
Process 11: Shipping
Tirapid currently cooperates with three major international express companies (DHL, FedEx, and UPS).
Materials and Surface Finishing Options
1. Aluminum 6061
The most commonly used type of aluminum for milling and turning, has good weldability and stable anodizing properties.
2. Aluminum 7075
7075, also known as aviation aluminum, is often used in parts with high hardness requirements, and it has high corrosion resistance.
3. Aluminum 5052
The ductility is the best of all aluminum types, most suitable for aluminum sheet metal parts.
4. Aluminum 2024
2# Aluminum, mostly used in military products, has good corrosion resistance and wear resistance.

6063 is cheaper than 6061 and is often used in construction parts with low requirements, such as door handles and decorative panels.
6. Other types of aluminum
Aluminum 2017, Aluminum 5754, Aluminum 6060, learn more.
After the aluminum parts are completed, they undergo secondary finishing treatment to finally achieve exquisite appearance and functional requirements. There are more than 30 surface treatment options commonly used by Tirapid, such as:
◉ Bead Blasting
◉ Chemical Conversion
◉ Powder Coating/Painting
◉ Chrome Plating
◉ Zinc Plating
“Tirapid has been a great partner for our aluminum parts fabrication. They have always provided us with high-quality products and excellent customer service. We would highly recommend them to anyone.”
“It is a high-quality machining and manufacturing company in China, which makes me more confident in my design, because I am very satisfied with the quality of Tirapid, and I am very relieved to hand over the design drawings to them.”
“The surface of the aluminum parts is very beautiful, there are no marks of hand grinding, and the dimensional tolerances are strictly carried out according to my design drawings. It is a very pleasant cooperation.”
Aluminum plate specification:
Thickness: less than 5mm (0.196inch),
Length & width: greater than 300mm (15.748inch),
Length & Width: less than 600mm (23.622 inches).
Flatness requirement: // 0.02mm or less
Part structure: There are large-area hollow structures and porous parts.
There are 6 solutions:
●Perform secondary leveling processing
When the flatness of raw materials does not meet the requirements, secondary leveling processing can be carried out.
●Increase the thickness of raw materials
Raw material thickness increased by 3-5mm. For example, if the thickness of the product part is 5mm, then the minimum thickness of the raw material needs to be 8-10mm.
●Drilling first and then milling the surface
The hole and shape of the product parts are processed first, and then the size of the surface is processed.
●Increase the number of milling
Increase the number of plane milling and perform multi-layer processing. After each process of milling, check whether there is any change in the plane size, and adjust the process in time.
●Reduce the amount of cutting each time
The amount of milling of the plane is minimized, and it is not necessary to process it in place at one time, and leave 1-2 hours for the material to release the stress.
●Milling direction is consistent
The running direction of the tool needs to be consistent, and the feed rate, depth of cut, and spindle speed cannot be changed arbitrarily.
The average price of aluminum sheets commonly used in China is USD6~10/KG.
Additional shipping and cutting charges apply for very small quantities. Then the total price of a piece of aluminum material will also rise accordingly.
Special aluminum plate prices are priced according to customization, such as imported materials and customized materials.
