As a special metal material, tungsten copper alloy through the hardness test, can reflect the chemical composition of its material, of course, with the continuous progress of detection technology, the material structure and the difference in the mechanical properties under the condition of heat treatment, can also be detected, it is widely used for quality detection.

When testing the hardness of tungsten-copper alloy, the shape and size of the specimen are relatively adaptable, and the efficiency of the test is relatively high. The main thing is that there is a corresponding relationship between the hardness of this material and other physical properties. When we test this material, we also need to test the ability of the metal to resist shaping deformation. This kind of test has some similarities from a certain point of view, so the test results can be compared with each other.

Tungsten-copper alloy is actually a kind of false alloy with two phase structure composed mainly of tungsten and copper elements. It is a metal matrix composite material. Due to the large difference in physical properties between copper and tungsten, it can not be produced by melting and casting, and is generally produced by powder metallurgy technology. The metal material has a wide range of uses, a large part of which is used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries.

The tungsten-copper alloy is sintered in liquid phase at 1300 to 1500℃ without being pressed. The materials prepared by this method have certain disadvantages in the uniformity, there are more gaps, and the density is usually lower than 98%. However, the sintering activity can be improved by adding a small amount of nickel to prepare ultrafine and nano powders, such as active sintering, mechanical alloying or oxide reduction method. So as to improve the density of tungsten copper, molybdenum copper alloys.
The above is to judge the quality of tungsten and copper alloy product standards and methods, I hope to help you.
