FAQ
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.
Q&A in the same category in this question
-
We are using carbide for press processing of stainless materials, but compared to SPCC, abrasion occurs quickly and parts must be replaced.
Stainless materials are hard and tough, which leads to greater abrasion and chipping of the tool.
We recommend using KX01, as it has superior toughness and resistance to heat, and is extremely hard. -
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. -
Which carbide material is the most resistant to abrasion?
The SS Grade carbide, made for abrasion resistance.
SS13 and SS15 have the hardness of HV2450 and HV2100, respectively.
These materials are not very tough, so it is recommended that you use them under a low load.
