Do you know how to test the Hardness of Copper? Well, copper plays an important role in the life of human beings. From the delivery of electricity to the supply of water, copper made all things possible.

It allows the electric current to pass through it with the same voltages; it is a good conductor of electricity.

Copper is used in electric appliances, almost every high-quality motors have copper wires in them.

In the past, the cutlery item is made from copper with are a good conductor of heat and cold. Copper itself is soft in nature but when you mix it with any other metal it becomes hard.







The main reason for the quality control of the materials is because they are fast and known to be non-destructive tests. There are some of the important measurements for the hardness of the materials described below:

押し込み硬度: これは、鋭利な物体から一定の圧力または荷重が加えられたときの変形に対する材料の抵抗を測定できる簡単な方法です。ロックウェル、ブリネル、海岸、ビッカースで測定できます。

引っかき硬度: in this method, we measure the resistance of the metal for permanent plastic deformation or fracture due to the friction of the sharp object on it. For the measurement of this method, the Mohs scale is used.

リバウンドハーネス: リバウンド硬度とは、ダイヤモンドチップハンマーを特定の材料の特定の高さから落下させて硬度を確認する方法です。ベネット硬度とリーブリバウンド硬度スケールは、リバウンド硬度の測定に使用されます。

The conversion table is used to convert one scale to another; it is used for the practices. There is an individual measurement scale for each of these classes.

The Hardness of Copper







Cold rolled copper is hard and is less malleable than soft tamper copper. It is a popular form of copper that is used for construction purposes.

The common mechanical properties of copper are strength, hardness, and ductility which determine its condition.

銅はソフトからハードに変換できます。銅のレンジングに使用される方法は冷間加工です。焼きなまし(軟質)銅の硬度は40HV、引張強度は200 N / mm2で、冷間加工後の硬度は110 HV、引張強度は360 N / mm2です。焼きなまし銅の延性は冷間加工銅よりも大きい。

You can increase the strength and the hardness of the copper easily. The common way of increasing the strength of the copper is through alloying, but it can affect the conductivity of the electricity.

The hardening process is done by heat treatment and can result in tensile strength of 1500 N/mm2.

Method for hardness




Scale B and C are only used for the thickness of 1mm and can be used for the copper alloys with this thickness. For the thin products the testing should be done through the superficial scales N and T. the hardness of the thin materials are checked with the microhardness scales.


It is a large and extensive indentation test, which is not suitable for thin and wire type materials. It is popular for testing large rods, bars, plates, and other heavy materials.

The testing of these materials will produce large indentations. The Brinell test is run only for materials that are thicker than the minimum of 3.2 inches.

Vickers and Knoop Tests

The Vickers test is also known as the diamond pyramid hardness test.

The load uses in this test is between 1 to 120 kg. If the weight of the material is less than 1 kg then the Vickers microhardness test will perform.  And the knop test is specially designed for the micro indentation hardness testing.
