Netizens ask: What type of tool steel is good for aluminum cold forging?
What is the best tool steel for aluminum cold forging molds? For those with low lifespan requirements, use affordable H13, while for those with long lifespan requirements, use high toughness LG die steel.
Aluminum cold forging molds are most afraid of sticking aluminum chips, which can eventually cause the mold to crack. Therefore, the performance of non stick materials should be given priority, followed by strength.
In fact, aluminum is very soft, and molds do not require too high hardness. Instead, high toughness should be prioritized. Mold steel with good toughness generally does not stick to aluminum shavings.
H13 is medium carbon steel with good toughness. Although its hardness is only 50HRC and its strength is lower, it is cheap and has good toughness. It is sufficient for making general aluminum cold forging molds.
HLG is a high toughness tool steel exclusive to Yuhui Company. LG’s toughness is 8-9 times that of DC53, with a hardness of 54-58HRC. Its toughness is so good that it does not break even when bent.
LG die steel with high toughness is the ultimate version of aluminum cold forging tool steel. LG die steel is used for cracking aluminum cold forging molds, stepping into the liberated area with one foot.
