What are the advantages of using high conductivity copper alloy for busbars?

High-strength and high-conductivity copper alloys have three main advantages:

1 Intensity. Copper is very soft and generally not used unless it has to be used (mainly for electrical and thermal conductivity). High conductivity copper is much harder than copper with an HRB of up to 55.

The HRB of copper cannot be measured in the soft state, even if it is made to about 30 in the hard state, it will become soft immediately after being heated. Copper is not wear-resistant, and high-conductivity copper is wear-resistant.

2 Electrical conductivity. The soft conductivity of copper is 100%, and the conductivity of high copper is between 98% and 104% depending on the strength.

3 Thermal conductivity. The highest thermal conductivity of copper is 398, and the high copper conductivity varies between 518 524W mk depending on the strength.

Copper alloy is an alloy composed of pure copper as a matrix and the addition of one or several other elements. Pure copper is purple-red and is also known as copper. Pure copper has a density of 1083 melting point and excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance.

It is mainly used to make electrical equipment such as generators, busbars, cables, switchgears, transformers, heat exchangers, pipes, flat plate collectors and other thermal conduction equipment for solar heating devices. Commonly used copper alloys are divided into three categories: brass, bronze, and cupronickel.

The high-strength and high-conductivity copper alloy is a high-thermal conductivity copper alloy developed by Taiyuan Thermal Research Technology, with a thermal conductivity of 524W MK, which is much higher than the thermal conductivity of copper.

The same shape of high copper conductivity radiator, heat dissipation performance is more than 30% higher than copper radiator!

The electrical conductivity, thermal conductivity, and mechanical strength are better than copper.

High conductivity copper is an ideal material for motors and electrode rings.

High conductivity copper is harder than copper, wear-resistant, and fast heat dissipation, and the conductivity is comparable to copper.

Wherever copper is needed, this material is the best.

Compared with pure copper, the advantage of high-strength and high-conductivity copper alloy is good thermal conductivity and high strength, which is an ideal material for motors, electrode rings and high-speed rail contact wires, and for cables, there is no advantage in using high-strength and high-conductivity alloy copper, the resistivity of any copper alloy is not as good as pure copper, the cable is used to transmit electrical energy, and the lower the resistivity, the better, and the manufacturing cost of high-strength and high-conductivity copper alloy is very high, so there is no need.

The specific properties are as follows: tensile strength: 370-390MPa, yield strength:

320MPa, Hardness: HRB54-55, Elongation: 9%, Thermal Conductivity:

524W mobile phones, aviation, aerospace, military and other industries are in urgent need of high thermal conductivity heat dissipation materials. The bottleneck in the development of battery cars, high-power motors, integrated circuits, etc. is also a problem of heat dissipation. For those with high requirements for heat dissipation, copper or copper alloy are mostly used for heat dissipation.

Its mechanical properties are also very good, and it is an ideal material for heat conduction and heat dissipation.

There is no benefit to the use of high-strength and high-conductivity alloy copper for cables, the resistivity of any copper alloy can not be as good as pure copper, the cable is used to transport electrical energy, and the lower the resistivity, the better, and the manufacturing cost of high-strength and high-conductivity copper alloy is very high, so there is no need.

High-strength and high-conductivity copper alloys (such as chromium zirconium copper alloys) are mainly used in the contact wire of high-speed rail, because the contact wire first needs high strength, of course, it also needs a relatively good resistivity (but no matter how good the resistivity is, it cannot be compared with pure copper, which is about 70 84% of pure copper), so improving tensile strength and resistivity are two contradictory aspects.

1. The high-strength and high-conductivity copper alloy is a high-thermal conductivity copper alloy developed and purified by Taiyuan Thermal Research Technology, with a thermal conductivity of 524W MK, which is much higher than the thermal conductivity of copper.

2. CPU, mobile phone, aviation, aerospace, military and other industries are in urgent need of high thermal conductivity heat dissipation materials. The bottleneck in the development of battery cars, high-hood power motors, integrated circuits, etc. is also a heat dissipation problem.

3. For high requirements for heat dissipation, copper or copper alloy is mostly used for heat dissipation. Its mechanical properties are also very good, and it is an ideal material for heat conduction and heat dissipation.
