Product Details

Under the wear-resistant working condition of bearing impact or strong impact, the Tungsten cold extrusion dies requires good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance.

1. Usually, medium, high, and medium to coarse grain sizes are selected, such as YG15C, YG20C, YL60, YG25C, etc.

2. The relationship between the wear resistance and toughness of hard alloys is contradictory: an increase in wear resistance will lead to a decrease in toughness, which in turn will inevitably lead to a decrease in wear resistance. Therefore, when selecting a joint number, it is necessary to meet specific usage requirements based on the processing object and working conditions.

3. If the selected brand is prone to early cracking and damage during use, it is advisable to choose a brand with higher toughness; If the selected brand is prone to early wear and damage during use, it is advisable to choose a brand with higher hardness and wear resistance.
