Basic Knowledge of Aluminum

What is Aluminum Material

Aluminum is a chemical element classified as a lightweight, non-ferrous metal. It belongs to the boron group of post-transition metals and typically forms compounds in the +3 oxidation state. The aluminum cation (Al3+) is small, highly charged, and has strong polarizing power, leading to more covalent character in its bonds. Aluminum is the third-most abundant element in Earth's crust.

It constitutes about 8% of the crust's weight. Extracted from bauxite ore through industrial mining, it was discovered in 1825 and became widely used after the Hall–Héroult process in 1886. Aluminum is often alloyed with other metals to enhance its properties. Common alloys include aluminum-copper, aluminum-zinc, and aluminum-magnesium.

Advantages of Aluminum

  • Lightweight nature
  • Corrosion resistance with a natural oxide layer
  • High strength-to-weight ratio
  • Excellent electrical conductivity
  • Good thermal conductivity
  • Malleability and formability
  • 100% recyclability without loss of properties
  • Non-toxic and safe for various applications

Applications of Aluminum

  • Vehicle bodies, engine components, and wheels
  • Aircraft and spacecraft
  • Structural beams, frames, and panels
  • Beverage cans
  • Conductors used in electrical transmission lines and power cables
  • Electronic devices and components
  • Boat construction
  • Sports equipment


CNC Machining Aluminum Buying FAQ

The cost of CNC machining Aluminum depends on the complexity and size of the part and the type of Aluminum. These variables will affect the type of machine that is required, the time it takes to produce the part and the cost of the raw material. We use machine learning algorithms to calculate the exact cost of any machinable part directly from a CAD file, based on millions of CNC machining orders we’ve previously processed.

CNC aluminum machining is a versatile and widely used manufacturing process that enables the production of a wide range of aluminum parts used in various industries, including aerospace, automotive, electronics, etc
Both "aluminum" and "aluminium" are correct spellings, but the usage depends on regional differences. In the United States, "aluminum" is the preferred spelling, while in many other English-speaking countries, including the United Kingdom, "aluminium" is the standard spelling.
Although steel is susceptible to corrosion, it remains stronger than aluminum. While aluminum gains strength in colder conditions, it tends to be more susceptible to dents and scratches than steel. Additionally, steel is less prone to warping or bending under the influence of weight, force, or heat.
Mild and carbon steels are usually cheaper than aluminum, while stainless steel is more expensive than aluminum. The cost comparison between aluminum and steel can vary depending on factors such as the type of alloy, market conditions, and the specific application. In some cases, aluminum may be more expensive than steel, but its lower density can offset costs in applications where weight reduction is important. Additionally, commodity price fluctuations can impact these materials' relative costs.
