CNC Aluminium impeller

What is Aluminum Machining?

Aluminum is one of the most popular machining materials thanks to its workability, strength, and versatility. What’s more, its low cost makes it perfect for prototypes, end-use products, and custom tools for molding. 

From standard grades like 6061 to high-quality aerospace grades like 7075, we have an aluminum alloy for every CNC machining project.

We also have the skills and the cutting-edge equipment to handle every challenge that might arise during production and improve the machinability of aluminum compared to our competitors. 

Our team has years of experience in machining with aluminum, as it makes up roughly 70% of used materials.

What are the characteristics of aluminum alloy impellers?

Aluminum alloy is a better alternative material to iron alloy and is suitable for applications with high strength-to-weight ratio. Aluminum alloys are one-third heavier than steel alloys of the same size. Aluminum alloy gears are corrosion-resistant and lightweight, and the passivated surface can protect them from oxidation and corrosion. This is similar to rust on steel alloys, where it coats the surface, protecting it from further damage. Aluminum alloys are more expensive than carbon steel, but cheaper than stainless steel. However, their ease of processing offsets the increased material cost.

Aluminum has proven to be highly versatile throughout history and continues to do so today. The aerospace industry continues to benefit from the properties of alloys to create safe, reliable and cheaper machined workpieces. Aluminum alloys begin to deform at 400° F, so they cannot be used in high temperature environments. There are many different types of aluminum alloy materials, and the most commonly used aluminum alloy materials for processing aluminum alloy gears are 2024, 6061 and 7075.
