What is CNC Machining?

Excellent Machinability: Aluminum alloy 6061 has excellent machinability, which means it can be easily and efficiently machined using CNC equipment. It has good chip formation properties, allowing for smooth machining processes and reducing the chances of tool wear or damage.

High Strength-to-Weight Ratio: Aluminum alloy 6061 offers a high strength-to-weight ratio, making it suitable for applications where lightweight components with good structural integrity are desired. This alloy provides sufficient strength and stiffness while keeping the weight of the machined part relatively low. It is widely used in aerospace, automotive, and other industries where weight reduction is essential.

Tolerances

Good Corrosion Resistance: Aluminum alloy 6061 exhibits good corrosion resistance. It is naturally resistant to atmospheric corrosion and can withstand exposure to various environmental conditions. This makes it suitable for applications where the machined parts may be exposed to moisture, humidity, or other corrosive elements.

Heat Treatable: Aluminum alloy 6061 is heat treatable, which means it can be strengthened through heat treatment processes such as solution heat treatment and aging. This allows for further enhancing the mechanical properties of the machined parts, including increased strength and hardness, while maintaining good machinability.

We also provide low-cost manufacturing of high-quality plastic parts. Our vacuum casting services offer short-cycle solutions for creating high-quality prototypes and low-volume production parts. Vacuum casting, or urethane casting, is a method that utilizes a silicone mold and a 3D printed master to produce vacuum-cast parts with consistent performance and production-grade quality. This technology does not require a costly initial investment, enables flexible and economical production, and hardens thermoplastic polyurethane in silicone or epoxy molds. The outcome is a vacuum-cast part that retains the shape of the original master model. The final dimensions of a vacuum-cast part are determined by the master model, the part's geometry, and the selected material.
