Stainless steel alloys have high strength, high ductility, good wear resistance, and strong corrosion resistance. They are easy to weld, process, and polish. Depending on their composition, they can be non-magnetic or magnetic in nature.

There are many types of stainless steel. Because it contains chromium, it prevents oxidation (rusting). Since all stainless steel looks the same, the latest measurement equipment must be used to carefully test the raw materials to confirm the characteristics of the steel used.

The commonly used stainless steel alloy 304 has excellent mechanical properties and excellent workability, making it suitable for kitchen accessories, storage tanks, and pipelines used in industry, construction, and the automotive industry. Another common stainless steel alloy 316 has the same mechanical properties as 304. It is often considered marine-grade stainless steel, which is strong and easy to weld. This material is highly corrosion-resistant and is well suited for construction, ship fittings, industrial pipelines, and automotive applications.

Aluminum is perhaps the most widely used material for CNC milling and is ideal for mechanical and exterior parts. Aluminum can generally be processed faster than other metals, making it the most economical method. Aluminum parts develop a protective layer when exposed to the environment, which increases strength and corrosion resistance. Given these high-quality material properties, CNC milled aluminum is ideal for use in the automotive, aerospace, healthcare, and consumer electronics industries. Specific applications include aircraft accessories, electronic housings, medical devices, gears, and shafts, making it an ideal choice for mechanical and exterior parts, with a good strength to weight ratio and excellent machinability.

Copper is known for its excellent electrical conductivity and thermal properties, making it ideal for electrical components and heat exchangers. Copper's electrical conductivity is second only to silver among all metals, so it is widely used in many electronic devices. In addition, copper has good corrosion resistance, which allows it to maintain stable performance under various environmental conditions.

In terms of heat exchangers, copper can not only effectively conduct heat, but also has a high oxidation resistance, thereby extending the service life of the equipment. This property makes copper widely used in air conditioning, refrigeration systems and industrial heating units. In the construction industry, copper pipes are often used in heating and cooling systems because of their ability to respond quickly to temperature changes and improve energy efficiency.

Cold rolled steel sheet is processed by cold rolling process, with smooth surface and uniform thickness, which provides a good foundation for its application in sheet metal processing, and the production cost is relatively low, which makes it advantageous in cost control and suitable for large-scale production. Cold rolled steel sheet is easy to form, suitable for surface treatment such as electroplating, baking paint, powder spraying, etc., which can better meet different design requirements. Cold rolled steel sheet has become one of the preferred materials due to its low cost, easy processing, good surface quality and wide range of applications. Due to its excellent mechanical properties and machinability, cold rolled steel sheet is widely used in various fields, including but not limited to electronic products, home appliances, furniture.
