Tungsten Copper Alloy vs Tungsten Nickel Iron Is A Comparison Of Two Different Alloys

Tungsten-copper alloy, like tungsten nickel copper, is a high-density tungsten alloy that is used in aerospace applications. If you are seeking an answer to this question, you have arrived at the correct location. tungsten copper alloy and tungsten nickel-iron alloy, and we will discuss the distinctions between the two in this post.
Tungsten nickel iron alloy, often known as W-Ni-Fe alloy, is an alloy composed mostly of tungsten (90-98 percent by weight) with nickel, iron, and copper components added for strength and corrosion resistance.

Heat Treatments on Tungsten Alloy

The heat treatment of tungsten alloy can significantly enhance the engineering properties. Take the example of heating W 95 tungsten alloy in a medium-frequency induction furnace. The strength and impact toughness will be markedly increased on the condition that the working temperature ranges from 850 to 900 °C and the heating lasts for 40 minutes.

Tungsten Copper Specification

Tungsten copper rods 80/20 and 90/10 exhibit a relatively high density, strengths, and a low thermal expansion rate. On the other hand, tungsten copper rods 60/40, 70/30, and 75/25 present high thermal and electrical conductivities and machinability. As an ISO certified tungsten manufacturer, we are capable of offering various types of tungsten copper rods that all meet a consistently high standard.

Copper Density and Hardness

In general, the hardness and density of both Molybdenum copper and tungsten copper decrease as their copper content increases. Tungsten copper with a copper volume fraction same as molybdenum copper has a higher density and hardness. Their electrical conductivities and thermal expansion rates go up with the increase of their copper percentage.

Tungsten Copper and Molybdenum Copper

The sintering temperature is higher than the copper melting point. Molten copper uniformly distributes on the structure of tungsten or molybdenum. Molybdenum particles tend to grow, as the figure shows. That may be related to the more manageable growth of Mo grains when holding temperature at higher sintering temperature.
