What Is Plasma Cutting?
Plasma cutting is a production process involving the use of ionized gas at temperatures above 20,0000C to melt and remove material from a workpiece. The gasses used here include argon/hydrogen, argon, or nitrogen. Plasma cutting is ideal for making high-precision parts with both general and industry-specific applications. You could get numerous benefits from using GCH’s custom plasma cutting service when making your product parts. Some of these advantages include:
- High Precision and Repeatability: Precision and repeatability are one of the major strengths of our plasma-cutting service. This is especially true when cutting shapes and angles from a metal workpiece. At GCH, we boast experienced operators with steady hands that guarantee a clean, highly precise cut.
- Versatility to Various Materials: Versatility is one of the major advantages of fabricating metals using plasma cutting. This is due to its ability to cut through conductive metals like iron, copper, stainless steel, steel, brass, and other metals. Besides, plasma cutting has one of the fastest cutting speeds, making it one of the best methods for metalwork.
- Suitable for Different Thickness: Unlike other metal cutting options, CNC plasma cutting can cut metals with various thicknesses. Our plasma cutting team at GCH can cut metals with thicknesses up to one-and-half inch and thicker.
- Complex Shapes: Plasma cutting facilitates the creation of various shapes, regardless of the complexity of their geometry. At GCH, we use plasma cutting to create intricate shapes, straight lines, and curves that would be impossible to make using other metal-cutting techniques.
- Energy Efficient: Energy efficiency is one of the reasons why more companies and businesses are leaning towards plasma cutting. At GCH, our CNC plasma machines are energy efficient, saving the long run cost.

Materials for Plasma Cutting
GCH’s laser cutting service is versatile and compatible with various materials, ranging from ferrous to non-ferrous metals, plastics, and other non-metals. Our laser cutting facility combines ultra-modern technology with skilled professionals to laser cut materials across different strengths, weights, and thermal properties. Here are some laser cutting materials available for your project.
Aluminum
Aluminum’s ability to reflect heat is one of the reasons why machinists favor this metal as a plasma-cutting material. It is also lightweight, non-corrosive, and highly malleable. Furthermore, aluminum is cost-effective, with a shorter plasma cutting time compared to other materials. Aluminum also has a high rate of recyclability, which helps reduce waste in the long term.
Subtypes: 2024, 5052, 5083, 6061, 6063, 6082, 7075
Steel
Steel is one of the most popular metals in machine shops due to its high machinability. Asides from machinability, steel has high tensile strength, ductility, and malleability. It is also very durable, with an aesthetically pleasing appearance. One major reason steel is ideal for plasma cutting is its high weldability, which allows it to withstand the stress caused by heat from the plasma cutter.
Subtypes: 1018, 1020, 1025， 1045， 1215， 4130， 4140， 4340， 5140，A36，ST37
Stainless Steel
Stainless steel is a metal alloy that contains at least 11% chromium. The chromium content of this metal gives it a glossy appearance. This metal is ideal for plasma cutting due to its strength at high temperatures, as it performs better than most metals. Stainless steel also has a high tensile strength and good plasticity. Besides, stainless steel is quite easy to machine.
Subtypes: 201, 303, 304, 316, 316L, 420, 430, 431, 304
Finishing Options for Plasma Cutting
Parts made using plasma cutting usually feature excellent finishes. At GCH, we offer various custom finishing options that boost the produced part’s functionality, appearance, and durability.
| Name | Materials | Color | Texture | Thickness | |
 | Anodizing | Aluminum | Clear, black, grey, red, blue, gold. | Smooth, matte finish. | A thin layer: 5-20 µm Hard anodic oxide film: 60-200 µm |
 | Beed Blasting | ABS, Aluminum, Brass, Stainless Steel, Steel | N/A | Matte | 0.3mm-6mm |
 | Powder Coating | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Gloss or semi-gloss | 5052 Aluminum 0.063″-0.500” 6061 Aluminum 0.063″-0.500” 7075 Aluminum 0.125”-0.250″ Mild Steel 0.048″-0.500” 4130 Chromoly Steel 0.050″-0.250” Stainless Steel 0.048″-0.500” |
