1. Difference in intensity:
Steel: Steel is a versatile metal whose strength is what makes it remarkable. Carbon steel, in which the main alloying components are carbon and iron, is the most common type and has excellent strength. By adding other elements, such as chromium, molybdenum, nickel, etc., alloy steel can improve its wear resistance and corrosion resistance, making it suitable for more challenging environments. Due to its sturdiness, steel is widely used in construction, bridges, automobile manufacturing, and more.
Aluminum Alloys: Aluminum alloys have high strength relative to their weight. Through alloying, aluminum alloys can be made stronger and harder, making them suitable for many industrial applications. The lightweight properties of aluminum alloys make them ideal for use in the aerospace and automotive manufacturing industries, reducing structural loads and improving fuel efficiency.
Copper: Copper is relatively soft, which makes it less strong, but it has excellent electrical and thermal conductivity. This has led to widespread use of copper in electronics, electrical engineering and plumbing systems. In some applications, copper's softness and ease of processing are more important.
2. Differences in corrosion resistance:
Stainless steel: Stainless steel is "stainless" because it contains at least 10.5% chromium, which forms a dense oxide film that prevents further oxidation of the metal. This gives stainless steel excellent corrosion resistance in humid, acidic and salty environments and is therefore commonly used in the manufacture of kitchen appliances, building structures and chemical equipment.
Aluminum alloy: The oxide layer formed on the surface of aluminum alloy gives it good corrosion resistance. However, the corrosion performance of aluminum alloys is relatively poor in alkaline environments. Aluminum alloys are mainly used in applications such as lightweight structures and aircraft parts, where their corrosion resistance and lightweight advantages are fully utilized.
Copper: Copper is resistant to atmospheric oxygen and water vapor and therefore corrodes more slowly in dry environments. However, in humid environments, especially where salt is present, copper may develop a green patina due to oxidation. Despite this, copper is still widely used in architecture and art production.
3.Special alloy:
Titanium Alloys: Titanium alloys are valued for their excellent corrosion resistance, especially in marine environments and the chemical industry. Titanium alloy not only has high strength, but also has amazing corrosion resistance and is not susceptible to corrosion by seawater, acid and alkali. Therefore, it has wide applications in marine engineering, biomedical implants and other fields.
Nickel-based alloys: Nickel-based alloys function primarily in high temperatures and corrosive environments. They excel in aviation, petrochemicals, nuclear energy and other fields. For example, Inconel alloys maintain their strength at high temperatures while being highly resistant to oxidation and corrosion.

When selecting a metal material for Metal Parts, the needs between strength and corrosion resistance must be carefully balanced to ensure it performs well in a specific application. The unique properties of various metallic materials make them play key roles in different industrial and manufacturing fields.
