What are the raw materials of construction machinery forgings

The raw materials of construction machinery forging involve many kinds of materials, including steel, aluminum, copper, titanium, nickel and other alloy materials. These materials have different applications in different occasions, including some high strength steel with excellent performance in strength and hardness, as well as stainless steel, aluminum alloy and other materials with good corrosion resistance. This paper will introduce the raw materials of construction machinery forgings in detail.

 

First, steel material

 

1. Carbon steel

 

Carbon steel is a type of steel with carbon as the main alloying element, and its carbon content is usually between 0.12% and 2.0%. Carbon steel has high strength and is often used in the manufacture of high-strength construction machinery forgings, such as tracks, sprockets, chains, etc.

 

2. Alloy steel

 

Alloy steel is usually added with boron, molybdenum, cobalt, chromium, nickel, titanium and other alloying elements to improve the performance of steel to meet specific manufacturing requirements. Alloy steel is also widely used in construction machinery manufacturing, such as the manufacture of scraper excavator, large bulldozer, stone machine and other equipment.

 

3. Stainless Steel

 

Stainless steel is a kind of steel material containing more than 10.5% chromium, it has corrosion resistance, high temperature oxidation resistance, excellent mechanical properties and other characteristics, especially suitable for manufacturing those need high strength, corrosion resistance and beautiful parts, such as parts on construction machinery, fuselage, etc.

 

4. High strength steel

 

High strength steel has excellent mechanical properties and can withstand great bending and impact force, so it is widely used in construction machinery manufacturing. The material is generally low alloy steel, carbon steel and alloy steel as the base material, adding some special alloy elements, made of very high strength material.

 

Two, aluminum material

 

1. Aluminum alloy

 

Aluminum alloy is a kind of material composed of aluminum and other alloying elements, which has the characteristics of light weight, corrosion resistance, conductivity, etc., and is widely used in construction machinery manufacturing. Aluminum alloy can be made into various parts, such as frames, pit gears, flywheels, valves, radiators, etc.

 

2. Pure aluminum

 

Pure aluminum is a kind of aluminum material with a purity of up to 99.9%. It has good thermal and electrical conductivity, but its strength and hardness are relatively low. In construction machinery manufacturing, it is often alloyed with other alloy elements to meet the requirements of mechanical parts.

 

Three, copper material

 

1. Copper alloy

 

Copper alloys are usually made by adding other alloying elements, such as aluminum, zinc, nickel, etc., to improve their mechanical properties while maintaining good electrical and thermal conductivity. In the manufacture of construction machinery, copper alloy is often used in the manufacture of screw drive, bearing sleeve, washer, etc.

 

2. Pure copper

 

Pure copper refers to containing more than 99.99% of pure copper elements, with excellent electrical conductivity, thermal conductivity and plasticity, but the disadvantage is that its strength is relatively low, often add a small number of other elements, further improve its mechanical properties, so as to be suitable for construction machinery manufacturing.

 

Four, titanium material

 

Titanium alloy is a kind of low density, high strength, good corrosion resistance of metal materials, widely used in the manufacturing of construction machinery parts. Titanium alloy has the advantages of wear resistance, low coefficient of thermal expansion, excellent performance in strength, hardness, wear resistance, corrosion resistance and so on, become one of the important materials in construction machinery manufacturing.

 

Five, nickel material

 

Nickel-metal is an alloy containing nickel, often alloyed with iron, chromium, molybdenum and other elements to make high-performance metal materials. Nickel alloys have excellent toughness, heat resistance and corrosion resistance, so they are suitable for the manufacture of construction machinery parts in high temperature environments, such as heat exchangers, valves, acid resistant equipment, etc.

 

To sum up, steel, aluminum, copper, titanium, nickel and other alloy materials can be used as raw materials for construction machinery forgings, and because of its special composition, structure and properties to adapt to different construction machinery work nature, so as to provide material guarantee for the manufacture of high-quality, high performance, high efficiency and minimize energy waste of modern construction machinery products.
