About CNC Aluminum

CNC stands for Computer Numerical Control. This is a process that is used to create a desired shape by cutting away excess material. It is done through the use of computer-controlled cutting tools and machinery. CNC machining has revolutionized the way metal parts are made, especially in industries like automotive, aerospace, and medical devices

Aluminum is a lightweight and relatively inexpensive metal. It is also strong, durable, and easy to work with. Aluminum can be used in a variety of applications such as in the automotive industry, aerospace industry, construction industry, and the electrical power transmission system.

Aluminum has some properties which make it an ideal material for machining. It has low hardness which makes it easier to machine than other metals like steel or cast iron. Aluminum also does not corrode easily when exposed to air or water which means that it does not need to be painted or coated after machining unlike other materials like steel or cast iron.

The use of CNC aluminum has grown immensely, the production of CNC automotive parts and other CNC parts that are lightweight has been intense. Below are a few of the things you may not have known.

5 things about cnc aluminum

Aluminum Material: CNC Aluminum Machining

Aluminum is a lightweight, strong, and durable metal that is used in a variety of industries. It can be machined with relative ease and has a low cost per pound.

CNC aluminum machining is the process of using computer-controlled machines to cut aluminum into the desired shape. This process can be done on both large and small scales, depending on the desired use for the aluminum.

The process starts by loading an aluminum block onto a machine bed. The machine then drills out any material that is not part of the finished product. The machine then cuts out any shapes needed from the block of aluminum. Finally, it smooths out any rough edges left over from cutting with sandpaper or other similar materials.

Aluminum Grade

Aluminum is a metal with many qualities that make it desirable for a variety of applications. It is lightweight, durable, and has good corrosion resistance. The metal is also inexpensive, which makes it an attractive option for many industries.

The aluminum grade refers to the purity of the metal and how much it has been processed. The higher the grade, the more pure the aluminum and less processing that has been done to it.

Aluminum grades are designated by numbers from 1 to 7 with 1 being the lowest grade of purity and 7 being the highest grade of purity.

1xxx series aluminum alloy:

1100,1200 Aluminum 99% 1050 Aluminum 99.5%
Good formability, corrosion resistance, weldability, and low strength.
Household products, electrical appliances, conductive materials, etc. that do not require strength.

2xxx series aluminum alloy:

2017 Duralumin Cu4%, Mg0.5% High strength, poor corrosion resistance, corrosion protection must be done in the corrosive environment. Aviation materials, structural materials. 2024 Super Duralumin Cu4.5%, Mg1.5% The tensile strength reaches 50kg/mm2, and the corrosion resistance is poor. Corrosive environments must be treated with anti-corrosion.

3xxx series aluminum alloy:

3003 Mn1-1.5% Does not reduce the workability and corrosion resistance of pure aluminum to increase its strength. Daily necessities, building materials, containers, etc.
3004 Mn1-1.5%, Mg1% has higher strength than 3003. Aluminum cans, light bulb heads, colored aluminum plates, etc.

4xxx series aluminum alloy:

5005 Mg0.8% Excellent corrosion resistance, processability, weldability, surface gloss and other properties. Vehicle interior materials, building materials, etc.
5052 Mg2.5% representative alloy of medium strength (annealed 20kg/mm2), good formability and corrosion resistance. Ships, vehicles, construction materials, beverage cans.
5083 Mg4.5% non-heat-treated alloy has the highest strength and good weldability. Materials for welding structures such as ships, vehicles, and chemical plants.

6xxx series aluminum alloy:

6061 Mg1%, Si0.6%, Cu0.3% heat-treated alloy, good corrosion resistance, excellent high temperature processability, yield strength about 25kg/mm2, equivalent to SS41 steel. Construction materials, ships, vehicles, land structures, such as iron towers, cranes, etc.
6063 Mg 0.6%, Si 0.4% has excellent extrudability. Aluminum doors and windows, building materials.

7xxx series aluminum alloy:

7075 super duralumin Zn5.5%, Mg2.5%, Cu1.6% belongs to the Al-Zn-Mg-Cu series alloy with the highest strength among aluminum alloys, with a tensile strength of 60kg/mm2. Aviation materials, sporting goods.
7N01 Zn4.5%, Mg1.5% belongs to Al-Zn-Mg series alloy for welding structure, with high strength and good hardenability. Welding structural materials, materials for railway vehicles.

CNC Aluminum Prototype

CNC Aluminum Prototype is a type of prototype that is used to show the design of products. It can be used for many purposes such as to communicate with suppliers and customers.

A CNC aluminum prototype is usually made from aluminum 6061-T6, which is a metal that has good workability and processing properties. This type of prototyping is often used for mechanical parts that require high precision.

Other CNC Machined Aluminum Components and Parts: There are many different types of CNC machined aluminum components and parts. They include:

  1. ● Structural components
  2. ● Aircraft engine mountings
  3. ● Automotive engine mountings
  4. ● Motorcycle frames
  5. ● Electrical conduit fittings
cnc machined aluminum parts cylinder liner automotive parts & accessories
