Die casting dies are generally H13, SKD61,8407,8417 of hot die steel.

The fundamental and effective way to avoid early cracking of aluminum die casting die is to improve the purity of die steel and reduce or eliminate low melting point impurities. Improve the high temperature softening property of die steel, thus improve the anti-cracking property. Under this premise, do the steel forging ratio of the foot mold, cooperate with good heat treatment process, mold use, and maintenance. So as to extend the service life of the mold.

1) Choose the mold steel with high purity and low sulfur content, such as electroslag H13, 1.2344, 2344ESR, SKD61, DAC55, DHA1, 8407, W302, 8418, no sulfur 8407, no sulfur 8418...And so on.

2) Improve the high temperature softening performance, and select the mold steel with high molybdenum content, such as: high molybdenum H13, SKD61, 8407, 8407, no sulfur 8407, no sulfur 8418.

There are dozens of kinds of aluminum die casting die materials, the above-introduced aluminum die casting die materials, is a common type of steel in the market. The most commonly used aluminum die casting die materials are: electroslag H13, 2344ESR, SKD61, W302, sulfur-free 8407, sulfur-free 8418
