The part marking industry works with a wide range of metals, each with its own unique characteristics and properties that influence the choice of marking method and application. Here are some of the most common metals used in part marking

Stainless steel

Stainless steel is a popular metal for part marking due to its durability and resistance to corrosion. It is commonly used in applications where high-temperature resistance and chemical resistance are required, such as in the aerospace, automotive, and oil and gas industries.



Aluminum is a lightweight and versatile metal that is used in a wide range of applications, including aerospace, automotive, and consumer goods. It is often used for part marking due to its high reflectivity and the ability to create high-contrast markings using laser or chemical etching methods.


Brass is a copper-based alloy that is commonly used in applications where corrosion resistance and aesthetic appeal are important. It is often used in the manufacturing of plumbing fixtures, musical instruments, and decorative objects.


Copper is a soft and malleable metal that is commonly used in electrical applications due to its excellent conductivity. It is often used in the manufacturing of electrical components, such as circuit boards and wires.


Titanium is a lightweight and strong metal that is commonly used in aerospace and medical applications due to its high strength-to-weight ratio and biocompatibility. It is often marked using laser or chemical etching methods.

Carbon Steel

Carbon steel is a popular metal for part marking due to its strength and durability. It is commonly used in applications where corrosion resistance is not a concern, such as in automotive and construction industries.


Part marking is widely used in the metalworking industry, both for traceability and for aesthetic purposes. Here are a few key applications of part marking with metals:


Traceability: Part marking is commonly used in the metalworking industry for traceability purposes. By marking parts with unique identifiers such as serial numbers or barcodes, manufacturers can track the parts through the production process and identify them in the event of defects or quality issues.

Branding: Part marking can also be used for branding purposes. For example, a manufacturer may mark their metal products with their logo or name to establish brand identity and recognition.

Compliance: Part marking is often used to meet compliance requirements for various industries, such as aerospace or defense. For example, certain parts may need to be marked with specific symbols or codes to indicate compliance with industry regulations or standards.

Aesthetic purposes: Part marking can also be used for aesthetic purposes. Metal parts can be marked with intricate designs, logos, or patterns to enhance their appearance and add value.

Durability: Part marking with metals can provide a durable and long-lasting marking solution. Laser marking, for example, can produce a high-contrast and permanent mark on a variety of metal surfaces.

Anti-counterfeiting: Part marking can be used as an anti-counterfeiting measure, particularly for high-value or high-security products. For example, marking metal parts with unique identifiers or holographic images can help to deter counterfeiters and ensure product authenticity.




Metal Advantages

Metal marking is a popular method used in the part marking industry to label or identify different components. This method offers several advantages over other marking techniques, including:

Durability: Metal marking creates permanent and robust markings that can withstand harsh environments, including exposure to extreme temperatures, chemicals, and weather elements. It ensures that the markings remain legible and intact for a long time, reducing the need for frequent replacements.

Versatility: Metal marking can be used on a wide range of materials, including aluminum, stainless steel, copper, brass, and titanium. It is suitable for marking flat, curved, or irregular surfaces, making it an ideal choice for different components and applications.

Precision: Metal marking provides accurate and precise markings that are highly legible, even on small or intricate parts. It is an excellent choice for marking critical components that require accurate identification or tracking.

Cost-effective: While metal marking may seem expensive compared to other marking methods, it is a cost-effective solution in the long run. The durability and longevity of the markings reduce the need for frequent replacements, saving time and money in the long term.

Security: Metal marking can incorporate unique identification codes or serial numbers that can help identify and track different components. This feature enhances security and prevents counterfeiting or tampering of the parts.

In summary, metal marking is a versatile, precise, durable, and cost-effective method of marking different components in the part marking industry. Its unique advantages make it an ideal choice for different applications, including automotive, aerospace, medical, and manufacturing industries, among others.

Overall, the choice of metal for part marking depends on the specific application and the properties required for the final product. MS Part Marking works with a wide range of metals and employs a variety of marking methods to ensure durable and accurate markings for traceability, branding, and compliance purposes.
