Tungsten Alloy for Die Casting

tungsten alloy for die casting
Tungsten alloy has low thermal expansion and high thermal conductivity which are fundamental for heat checking resistance. The low thermal expansion guarantees low thermal stress. A high thermal conductivity reduces the thermal gradients and thereby the thermal stress by cooling the casting faster.
What is more, low erosion. Erosion of the die is important. Tungsten alloy material provides a low erosion rate due to its chemical resistance. This occurs because molten aluminum dissolves tool steel. Aluminum does not dissolve tungsten alloy, therefore you have a longer die life. This means you don't have to change the die or core rods as often, which results in less downtime. Die casting life can be up to 10 times longer with tungsten alloy.

Besides, we can manufacture tungsten alloy welding rod with the similar or even better properties to one type of famous brand rod. Properties of tungsten alloy for die casting have been shown as follows:
