Tungsten Anviloy for Die Casting

Thermal fatigue is one of reasons of tool end of life. Higher tensile strength and better thermal conductivity has the function of minimizing thermal fatigue and thereby improve tool life. Tool steel does a good job in many die casting applications, but its life decreases as casting temperatures increase. Heat checking is a thermo-mechanical fatigue process caused by thermal cycling, which creates cyclic stresses and strains in the cavity surface. Typical damage is the gradual growth of a network of cracks. Tungsten anviloy has low thermal expansion and high thermal conductivity which are fundamental for heat checking resistance. The low thermal expansion allows for 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 a problem. Tungsten anviloy provides a low erosion rate due to its chemical resistance. This occurs because molten aluminum dissolves tool steel. Aluminum does not dissolve tungsten anviloy, 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 life can be up to 10 times longer with tungsten anviloy.

Besides, we can manufacture tungsten heavy alloy products as the counterpart to Anviloy products. Properties of Anviloy products have been shown as follows:
