1. What is a copper bar/rod

Solid copper rods that are extruded or drawn are referred to as copper rods. Copper rods come in a variety of colors and finishes, including red, white, brass, and bronze. Different molding techniques and properties are used to create several types of copper rods. Processes used to manufacture copper rods include rolling, continuous casting, drawing, and extrusion.

Copper rod materials include H59, H59-1, H59-2, H59-3, H60, H60-2, H62, H63, H65, H68, H70, H80, H90; C1100, C1020, C2680, C2800, C2600, C2801 , C5191, C5210, C2200, C7521, C7541, C17200, C1070, C7701, QSn6.5-0.1, QSn8-0.3, QSn4-0.3, BZn18-18, BZn15-20, CuBe2, etc.

6. Applications and characteristics of copper bar/rod

Pure copper is shaped into components with a predetermined width to create copper strips. Due to copper's intrinsic qualities, the components have a number of features that make them suited for usage in a range of industrial applications, including outstanding electrical conductivity.

Characteristics and applications of copper bar/rod

1. Electrical conductivity: Copper, which is widely used in the electronic industry for circuit boards, transformers, wires, cables, etc., is a superior electrical conductor.

2. Thermal conductivity: Due to their great thermal conductivity, copper bars/rods are frequently employed in radiators, heat exchangers, and other heating appliances.

3. Plasticity: Copper bar/rod may be molded into a variety of shapes with ease. Processing techniques that are frequently used to create materials for handicrafts and construction decorations include stamping, bending, cutting, etc. 

4. Corrosion resistance: Copper bars/rods are frequently employed in the manufacture of equipment for the chemical industry, the maritime industry, and other settings due to their relative corrosion resistance.

Purity measurement:

Measuring the purity of brass can be measured using Archimedes' principle, measuring the volume and mass of the sample, and then calculating the proportion of copper contained in the brass based on the density of copper and zinc.

Plain Brass: It is an alloy composed of copper and zinc. When the zinc content is less than 39%, zinc can dissolve in copper to form single-phase a, which is called single-phase brass. It has good plasticity and is suitable for hot and cold pressure processing. When the zinc content is greater than 39%, there is a single-phase and b-solid solution based on copper and zinc, which is called dual-phase brass. b makes the plasticity small and the tensile strength increases. It is only suitable for hot-pressure processing. If it continues to increase If the mass fraction of zinc is too high, the tensile strength will decrease and it will have no use value.

The code name is represented by "H + number", H represents brass, and the number represents the mass fraction of copper. For example, H68 represents brass with a copper content of 68% and a zinc content of 32%. Cast brass has the word "Z" in front of the code. For example, ZH62 or Zcuzn38 represents a casting with a zinc content of 38% and the balance is copper. brass. H90 and H80 are single-phase, golden yellow, so they are collectively called gold, and are called coatings, decorations, medals, etc. H68 and H59 are duplex brass, which are widely used in structural parts of electrical appliances, such as bolts, nuts, washers, springs, etc. Generally, single-phase brass is used for cold deformation processing and duplex brass is used for hot deformation processing.

Special brass: A multi-component alloy formed by adding other alloying elements to ordinary brass is called brass. Commonly added elements include lead, tin, aluminum, etc., which can be called lead brass, tin brass, and aluminum brass accordingly.

Mainly to improve the tensile strength and improve the processability code: "H + main plus element symbol (except zinc) + mass fraction of copper + main plus element mass fraction + other elements mass fraction". For example: HPb59-1 means lead brass with a mass fraction of 59% copper, 1% mass fraction of lead as the main additive element, and zinc as the balance.
