Most Common Metals Used in CNC Metal Casting

One of the main reasons for the popularity of CNC metal casting is its compatibility with different metals. Highly accurate CNCmachining parts can be produced using a multitude of materials. Some of them are listed below.

We are known as Top Machine tools supplier across USA and Europe.

·         Stainless Steel:

Stainless steel or SS is undoubtedly the most common type of metal used for precision CNC manufacturing. Favored for its corrosion resistance and strength, the metal is used everywhere from surgical equipment to electronics hardware and many more. of the other alternatives such as molybdenum and chromium cannot resist corrosion. The metal is known for its versatility, durability, lightweight, broadening its application across industries.

 

 

·         Carbon Steel:

Carbon steel is another popular metal considered for precision machining. It is available in several formulations, and one can select them based on your requirement of the application. Carbon steel is chosen due to its affordability, durability, long shelf life, eco-friendly nature, and so on. It is known for offering a high level of machinability and weldability while maintaining a high level of toughness.

·         Aluminum Alloy:

Aluminum alloy is perhaps the most popular choice for CNC metal casting. Owing to its high level of machinability, corrosion-resistance, and lightweight feature, it is largely used in diverse segments such as for producing automotive parts, food containers, bicycle frames, aircraft components, and more.

·         Nickel-Based Alloy:

Like stainless steel, nickel-based alloys are preferred for their excellent corrosion resistance property. Nickel is coupled with zinc, iron, manganese, copper, chromium to achieve the desired results. Alloys with a high level of nickel are often used in chemical handling applications.

·         Copper-Based Alloy:

Copper-based alloys have high resistance against corrosion, making these metals a great choice for long-term cost efficiency. Brass is one of the most popular copper-based alloys. Established as one easiest and cost-effective metal to use with CNC metal casting services, it is chosen to make complex parts demanding sophisticated features.

·         White Iron:

It is known for its high compressive strength and outstanding wear resistance. Also, it retains its toughness for a specific period after exposure to extreme heat. Some white iron types consist of a high level of chromium to increase performance for high-temperature applications.

·         Grey Iron:

It is a type of iron known for its appearance and color caused by graphite fractures in the material. Based on the class of this metal, different levels of strength and machinability can be achieved. Grey iron is used where stiffness is more important than its tensile strength of the component such as electrical boxes, decorative castings, pump housings, and more.

·         Ductile Iron:

Ductile iron has a higher level of tensile strength than grey iron, allowing their usage in a wide variety of market segments. Popularly known as ductile cast iron, it is known for its elongation capacity, wear resistance, impact strength, and fatigue resistance owing to the sphere-shaped structures in the metal.

Since the list of metals for precision CNC manufacturing is detailed, to the metal selection process needs to be thoroughly understood to be able to select the right metal or alloy.
