Tungsten copper rod wear resistance is also called as abrasion resistance or durability, which refers to the capability of rubbing against sand paper, and represented by the reciprocal of wear rate (dt / dV or dL / dV). More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Measurement Since different friction materials and test conditions, it can be represented by wear index or the consumption of abrasion tester (g/cm2) or its reciprocal. In addition, it refers to the resistance of…

Tungsten copper rod phase diagram is the picture under metallographic microscope, which reflects the chemical components of metal or alloy and the state or interactions. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Application Indentify the structure after cold, hot process; Indentify and evaluate the non-metallic inclusions in steel; Measure the decarburized and carburized layer; Check the cracks, determine the content of oxygen and evaluate the granularity; Analyze the fracture morphology.

Tungsten copper rod melting point is the balance that tungsten copper rod in solid state and liquid state chemical potential. In other words, it is the temperature solid state converts into liquid phase, which usually represented by Tm. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Tungsten copper melting point is not constant, there are two factors have a great effect on melting point. The one is pressure: the melting process is also the volume expanding process, when the…

Tungsten copper rod CTE (Coefficient of Thermal Expansion) represents the variation of length by temperature changes under constant pressure. And the unit of metal CTE is 1/℃. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Tungsten copper rod CTE can be divided into linear expansion coefficient α, superficial expansivity β and volume expansion coefficient γ. When the temperature change is not very large, α becomes a constant, it can represent both solid and liquid volume expansion as follow: Vt…

The capability of current conduction is called as conductivity. Different proportion tungsten copper rod has different conductivity, which higher Cu content rod has higher electrical conductivity. Usually use σ to represent its conductivity. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Generally, metal, semiconductor, an electrolyte solution or molten electrolyte, and some non-metal can conduct electricity. Tungsten copper rod belongs to metal conductor. The conducting capacity of no-electrolyte depends on the outer free electrons and atomic crystal structure, such…

The capacity of resisting a hard object pressed into its surface is called as hardness in physics. And tungsten copper rod hardness is the basic indicator to evaluate the materials if soft or hard. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Tungsten copper rod hardness can be divided into scratch hardness, indentation hardness and rebound hardness. Scratch hardness: Mainly used to compare the hardness of minerals, the method is selected from the soft end of a hard rod…

The mass of some substance per unit volume is called density of this material, which is a reflection of the physical properties of the material in physics. Tungsten copper rod density is a kind of feature itself, which does not change with mass or volume. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Weighing: Weigh the mass of metal block by balance, record as m; The amount of water injected into the cylinder, readout volume V1; Get the block…

Compared with common blank rod, it has better performance in roughness and surface quality. And common copper electrode has large consumption, low precision and efficiency when processing tungsten carbide, high carbon steel, hardened tool steel, while tungsten copper has greatly improved the efficiency and accuracy. Tungsten copper not only has good electrical conductivity, high soften temperature, wear and corrosion resistance, long service life and low frequency of electrode correction, but also save the production costs based on improving efficiency. More…
