Tungsten copper rod thermal conductivity is that when the vertical temperature gradient down 1 ℃ / m, the heat through unit horizontal cross-sectional area per unit time pass, which is represented by λ or K. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Tungsten copper rod thermal conductivity makes no difference to the pressure, but greatly influenced by the temperature. Most of thermal conductivity of pure metal and liquid decrease with increasing temperature, but water is an exception; thermal…

Tungsten copper rod impact toughness reflects the resistance to external impact load and generally represented by ak or Ak, the units of J/cm2 and J (joule). More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html The practical significance of impact toughness indicator is to reveal the brittle tendency of material. According to the temperature of impact test, it can be divided into three types, room temperature, low temperature and high temperature impact test; and according to the gap shape it…

Tungsten copper rod flexural strength refers to the resistance to bending without broken. It usually uses three-point or four-point test for evaluation. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Measurement Flexural strength (GB / T 6569-86), or ISO 14704-2000 test. Flexural strength test is divided into three-point bending and four-point bending. Each point should be measured 5 times at least (10 in standard) and obtain the average. Flexural strength test conducted on universal testing machine. Used as test…

Tungsten copper rod corrosion resistance is the critical value of homogeneous plastic deformation to plastic deformation localized concentration of the transition, which is also the maximum carrying capacity under static stretching conditions. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Type In the role of a pure tensile force, without fracture can withstand the maximum load and the ratio of the width of the stretched membrane that, usually N / 5cm to represent. It is divided into the warp…

Tungsten copper rod corrosion resistance is one of significant properties to evaluate tungsten copper products. It mainly refers to the chemical stability and depends on components, chemical properties and morphology. More details of tungsten copper rod please visit http://www.tungsten-copper.com/tungsten-copper-rod.html Optimization Improve the thermodynamic stability of tungsten copper alloy (increase electrode potential); Reduce the anode activity: Reduce the alloy cathode active phase of adaptation cathode control corrosion, non-passivated metal: Form the dense amorphous protective film on the surface of alloy, such…

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…
