Why should you choose machined aluminum for your project?

Machined aluminum is ideal for projects requiring strength, durability, and precision. Aluminum is a lightweight yet strong material resistant to corrosion, making it suitable for various industries. CNC aluminum is produced using a computer-controlled milling machine that ensures accuracy and consistency in the finished product. Aluminum can be customized to meet specific requirements, with intricate designs and complex shapes possible. It is also easy to machine, making it a cost-effective choice for the automotive, aerospace, and medical industries. Overall, aluminum is a versatile and reliable material that offers numerous benefits to those looking to manufacture high-quality, long-lasting products.

Finishes for machined aluminum

Aluminum can be finished in various ways to achieve aesthetic and functional outcomes. One standard finish is an anodized coating, which uses an electrochemical process to create a durable, corrosion-resistant layer that can be colored in various hues. For a high-end look, aluminum can be mirror-polished to create a reflective surface often used in decorative applications. Black oxidation is another finish option for aluminum, which chemically alters the surface to create a deep, black color often used in the automotive and aerospace industries. Bead blasting is another option, using abrasive particles to create a matte or textured surface finish. Ultimately, the finish chosen will depend on the intended use of the CNC-machined aluminum part and the desired look and performance properties.
