Honmor uses high-grade aluminum alloys and advanced CNC laths to manufacture Aluminum Turned Parts with spindle runout less than 0.001mm achieving precise tolerance to 0.002mm. The nature oxide layer of aluminum provides basic function of corrosion resistance, meanwhile, Honmor is able to further enhance it depending on customer’s requirements by a series of surface treatment such as: anodizing and powder coating. Thus, whether clients want to order customized small-batch Aluminum Turned Parts for electronic connectors or purchase large-batch components for electronic vehicle battery housings, Honmor can offer customized solution that balances precision, weight, and cost, simplifying the process of procuring high-performance aluminum components.

Core Advantages

Lightweight & High Strength-to-Weight Ratio

The low density of aluminum makes CNC Aluminum Turned Parts 60%-70% lighter than steel equivalents, while its tensile strength provided by heat-treated alloy of 572MPa is comparable to some steels. This edge is vital for weight-sensitive industries like automotive and aerospace, in these industries, weight reduction directly improves fuel efficiency and ability of loading. For example, the 6061-T6 aluminum shafts produced by Honmor are 40% lighter than steel shafts which reduces 5kg for the vehicle’s overall weight and improves 8% battery range. When customers procure Aluminum Turned Parts for weight-sensitive applications, Honmor recommend to adapt the optimal alloy to meet performance requirements without redundant weight.

Excellent machinability and rapid production cycles

Aluminum has low hardness and cutting resistance, which makes it 30%-50% faster to process than stainless steel. Honmor’s CNC lathes were equipped with high-speed carbide tools (cutting speed up to 3000m/min for aluminum), it makes Honmor is able to produce more than 2000 pieces of Aluminum Turned Parts within one day. With this advantage, Honmor shorten the production cycle efficiently and low unit costs. For example, a aluminum bushing made of 6061-T6 just need 30 seconds to machine, compared to stainless steel which need cost 1 minute for same size. Such efficiency is ideal for customers with large quantities. One of a European electronics manufacturer purchased 50000 aluminum connectors from Honmor received all parts within 10 days, 5 days faster than their order of steel connector.

Customization surface treatment for enhancing performance

The surface of Aluminum Turned Parts can be modified to meet special environmental and functional requirements, thus, Honmor provides a series of customized surface treatment as per different needs from customers. Anodizing generate a thick, wear-resistant oxide layer(5-25um), which is good for enhancing corrosion resistance (withstanding 1000 hours salt spray tests) and color customization (black, silver, gold) is allowed for aesthetic parts (such as consumer electronics casings). Powder coating provides a durable and scratch-resistant layer for outdoor components (such as automotive exterior brackets). For heat-sensitive parts (such as LED radiator), Honmor uses thermal conductive coatings to improve heat dissipation. One of a American LED lighting company procured customized anodized Aluminum Turned Parts from Honmor, these radiator maintain stable performance and without corrosion or wear after using 2000 hours.

New energy vehicles

CNC Aluminum Turned Parts are also widely used in the field of automotive systems to reduce weight and improve efficiency. Some of typical applications such as: electronic vehicles’ battery terminal posts (6061-T6, anodized for corrosion resistance), transmission bushings(7075-T6, high strength for load-bearing), and engine oil caps (5052-H32, can be formed as complex shapes). Honmor commit itself to provide Chinese leading manufacturer of new energy vehicles with 6061-T6 aluminum battery terminal posts, these parts have tolerance of ±0.002mm, ensuring tight electronic connections. Test reports indicate that the terminal posts still maintain stable conductivity after 50000 charge-discharge cycles, which meet the requirement of vehicle’s 8-year service life. Moreover, Honmor’s aluminum transmission bushings are 35% lighter than steel steel bushings, it reduces 3kg weight of transmission system and improve fuel efficiency by 4%.

Consumer electronics and electrical equipment

In the field of electronics, Aluminum Turned Parts are famous for its outstanding ability of heat dissipation and lightweight design, some of common applications include LED heatsinks, USB-C connector shells and power adapter housings. A South Korean smartphone manufacturer customized a large batch of 6061-T6 aluminum LED heatsinks from Honmor with surface roughness of Ra0.2um to maximize heat dissipation area, and their anodized finish (black) matches the phone’s design. The radiator lowed the operating temperature of LED module by 12℃, which extend the LED’s lifespan by 50%. As for power adaptor, the 6061-T6 aluminum housings ensure that fit with internal components tightly, preventing dust and moisture ingress.

Aerospace and defense

In aerospace applications field, high-strength and light-weight Aluminum Turned Parts are vital for it. Such as aircraft sensor housings, satellite antenna mounts and drone motor shafts. Honmor manufactures 7075-T6 aluminum sensor housings for a U.S. aerospace firm—these parts with requirement of concentricity tolerance of ±0.001mm to ensure precise sensor readings and their type three anodized surface is able to resist wear from aircraft vibration. The housings passed the firm’s 10,000-hour vibration test (10-2,000Hz) with no dimensional changes, meeting NASA’s aerospace standards. For drone motor shafts, Honmor’s 7075-T6 aluminum parts are 45% lighter than steel shafts, increasing the drone’s flight time by 20 minutes—critical for long-endurance missions.

Procurement and Customization Process

Demand and design communication

Customers share their requirements about CNC Aluminum Turned Parts including 2D/3D drawings(CAD, SSTEP and IGS are supported), alloy grade preference, tolerance grade, surface treatment and quantity. Honmor’s engineers will inspect them to evaluate machinability. For example, if drawing specifies a thin-walled aluminum part that risk from deformation during machining process, engineers would suggest increasing thickness to 1.2mm or using alloys which are easy to shape to maintain precision. Meanwhile, they also provide customized surface treatment based on application scenarios.
