01 What are Alloy Materials

Alloy materials refer to materials composed of two or more metal or non-metal elements. They possess excellent mechanical, chemical, and physical properties and are widely used in various industrial fields.

02 Classification of Alloy Materials

Depending on the composition of the alloys, alloy materials can be classified into the following categories:

1. 1. Alloy steel: Based on iron as the primary element, its performance is enhanced by adding appropriate amounts of other elements, such as carbon steel and stainless steel.
2. 2. Non-ferrous metal alloys: With copper, aluminum, magnesium, zinc, lead, etc., as the primary elements, their performance is improved by adding appropriate amounts of other elements, such as brass, bronze, and aluminum alloys.
3. 3. Rare metal alloys: With tungsten, molybdenum, niobium, titanium, etc., as the primary elements, their performance is enhanced by adding appropriate amounts of other elements, such as tungsten-molybdenum alloys and titanium-niobium alloys.
4. 4. Magnetic alloys: With iron, cobalt, nickel, aluminum, etc., as the primary elements, their magnetic properties are adjusted by adding appropriate amounts of other elements, such as permanent magnet materials.
5. 5. Special alloys: With steel, copper, aluminum, magnesium, etc., as the primary elements, they meet specific application requirements by adding appropriate amounts of other elements, such as high-temperature alloys and corrosion-resistant alloys.

03 Characteristics of Alloy Materials

Alloy materials have the following characteristics:

1. 1. High strength: The addition of other elements in alloy materials can enhance the mechanical properties of the base elements, thereby increasing the strength of the alloy.
2. 2. Good wear resistance: The addition of other elements can improve the hardness and wear resistance of the material.
3. 3. Good corrosion resistance: The addition of other elements can enhance the material's corrosion resistance, extending its service life.
4. 4. Good electrical and thermal conductivity: The addition of other elements can improve the material's electrical and thermal conductivity, broadening its application fields.
5. 5. Easy to process: The addition of other elements can enhance the material's machinability, making it easier to process and shape.
