2 Useful Tips for Selecting Aluminum CNC Parts
2026-03-24
Tips 1: Choose an Aluminum Material That Suits Your Needs
Due to its unique characteristics—specifically its lightweight nature and non-magnetic properties—CNC-machined aluminum parts are widely utilized. Aluminum is remarkably versatile and can be easily fabricated into a vast array of shapes and forms—ranging from the thin, lightweight foil used for packaging to the robust plates employed to reinforce storage tanks. Furthermore, it can be drawn into fine wires or manufactured into beverage cans. While pure aluminum is inherently soft and possesses relatively low tensile strength, its structural integrity can be significantly enhanced through the addition of trace amounts of alloying elements such as copper, magnesium, or zinc.
In the industrial metals market, aluminum is a relatively newcomer; its history of large-scale production spans just over a century. Consequently, the design of aluminum components presents a number of specific challenges that require careful consideration. Aluminum components feature in 70% of our company's product lines. We would be honored to leverage our specialized expertise and extensive experience to assist you in navigating these complexities.

How to Choose Aluminum CNC Parts?
Below are some of the most commonly used aluminum grades in CNC machining:
● Aluminum 6061 – This alloy is mainly applied to 3-axis, 4-axis, and 5-axis CNC milling machines. It possesses excellent mechanical properties, is easy to weld, and has a hardness ranging from medium to high. In addition, it is highly malleable, making anodizing and bending processes simple to carry out.
● Aluminum 7075 – It is widely utilized in industries like bicycles and wheelchairs. This alloy offers high impact
resistance and superior corrosion resistance, but its specific properties make it inappropriate for welding purposes.
● Aluminum 2024 – It is extensively used in the aerospace and military industries, featuring good wearability and strong corrosion resistance even in harsh environments.

Tips 2: Select the Suitable Surface Finish for Aluminum CNC Parts
There are three distinct types of aluminum anodizing available, which is a widely favored finishing method for metal components. Anodizing not only delivers exceptional corrosion protection but also enhances the visual appearance of the parts.
● Type I-Chromic Acid: This type creates an ultra-thin yet durable coating. It is commonly used for welded components and assemblies, as well as a primer prior to painting. Just like all anodized surfaces, it is non-conductive.
● Type II-Sulfuric Acid: More durable than Type I, this anodizing option provides an extremely long-lasting finish. Its applications cover a broad range of products, including carabiner hooks, flashlight grips, motorcycle components, and hydraulic valve bodies.
● Type III-Hard Anodize or Hardcoat: Renowned for its remarkable thickness and sturdiness, this anodizing type is highly desirable across multiple industries. Its versatility enables its use in automotive, aerospace, heavy machinery, marine, general manufacturing, and military/law enforcement sectors.
