What are the Requirements for Die Steel for Aluminum Die Casting?

The production of aluminum alloy die-casting requires the use of die steel. What is die steel? Die steel is a kind of steel used to make molds such as cold die, hot forging die, and die-casting die; then what is the demand for die-casting of aluminum die-casting? China Die Casting Parts Factory will talk about you:

First, high tempering resistance and thermal fatigue resistance

Generally, in the aluminum alloy die-casting production, the molds are continuously produced for a long time, so the temperature must not be low, but will reach the highest point, so the mold steel must have certain hardness and no sticking;

Second, sufficient strength, hardness, plasticity and heat resistance

Aluminum Alloy Die Cast Part is produced by pouring molten metal into the mold during molding, so the mold steel must have sufficient high-temperature strength and toughness;

Third, good thermal conductivity

The first point is that the mold is at a high temperature of 600-700 ° C for a long time, and good thermal conductivity is necessary;

Fourth, good resistance to damage of molten metal

It is also in a state of high temperature, high temperature casting melt damage, Die Casting Mould does not have a little damage resistance is not acceptable;
