Metal Alloy 99.995% Copper Round Bar Grind Surface

About Metal Alloy Copper Round Bar Grind Surface: 
Copper round bar is a widely used metal material with excellent conductivity, thermal conductivity, and excellent processing performance, making it important in many fields. This article will provide a detailed introduction to copper bars' production, classification, application scenarios, and selection methods.
The first step in the production process of copper bars is to melt the copper. The melting point of copper is relatively low, around 1000 ℃, so producing copper bars requires high-temperature melting furnaces. During smelting, copper raw materials are added to the furnace and melted into copper liquid at high temperatures. To ensure the quality of the copper rod, it is necessary to strictly control the temperature inside the furnace during melting to maintain the purity of the copper liquid.

After the melting is completed, the next step is the drawing process. The drawing of copper bars is divided into multiple steps, including mold design, copper liquid injection, preliminary drawing, and fine drawing. During the drawing process, attention should be paid to controlling the diameter and length of the copper rod to ensure that it meets production standards. After the preliminary drawing, the copper rod must be finely drawn to further adjust its diameter and length to ensure dimensional accuracy.

After the drawing is completed, the copper rod must undergo heat treatment. The main purpose of heat treatment is to eliminate the internal stress of copper bars and improve their hardness and wear resistance. During the heat treatment process, it is necessary to strictly control the heating and cooling time to ensure that the performance of the copper rod is effectively improved.

Properties: good electrical conductivity, thermal conductivity, ductility, corrosion resistance, wear resistance. 

There are various classification methods for copper bars, and according to different classification standards, copper bars can be divided into different types. The following are several common classification methods:

Classification by diameter: Copper rods can be classified into different specifications based on their diameters. For example, a copper rod with a diameter of 10mm is called a 10mm copper rod.

Classification by Material: According to the different materials used for copper rods, they can be divided into red copper rods, brass rods, bronze rods, etc. Among them, red copper rods have the highest purity, the best conductivity, and thermal conductivity and are commonly used as electrical connectors; Brass rods have good wear and corrosion resistance; Bronze bars have good strength and hardness.

Classification by surface treatment method: According to the different surface treatment methods of copper bars, they can be divided into galvanized copper bars, chrome-plated copper bars, nickel-plated copper bars, etc. These specially processed copper bars can meet the needs of specific application scenarios and improve their service life.

The application scenarios of copper bars are very wide, and the following are some main application areas:

Electrical field: Copper bars are mainly used as conductors, cable sheaths, and distribution equipment in the electrical field. Due to its excellent conductivity, copper bars are one of the key materials for power transmission and distribution.

Architecture: In the field of architecture, copper bars are often used to make architectural artworks, decorations, and connectors, wires, and pipes in buildings.

In the automotive industry, copper bars are mainly used for manufacturing engine components, brake system components, and electrical accessories.

Mechanical processing field: Copper bars are mainly used in mechanical processing to manufacture various components, such as gears, bearings, piston rods, etc.
