What grades do you recommend for punches, dies, and strippers?
It depends on the conditions, so it's hard to say. It also depends on the user.
EF10 for punches and KD20 for dies are used relatively often.
There are cases where ultrafine alloys are not suitable for wire processing such as die-cut blades and strippers (e.g., electrolytic corrosion), so please consult with us first. -
Can A10W be considered for use in electrical machining?
We believe A10W can be used safely even in electrical machining.
Fine particle grain cemented carbide inhibit crack propagation through mixing coarse-sized grain, and the heat affected layer's thickness is reduced through lowering the amount of Co. This is why we recommend A10W for wire EDM. -
We are using fine grain and ultra fine grain carbide parts with wire cutting and EDM machines, but chipping occurs often during use.
Try our A10W.
This material maintains the transverse rupture strength of KD20, while having resistance to thermal cracking during EDM/WEDM improved.
