Standar lingkungan EU RoHS 2.0 njaluk supaya konten timbal (Pb) kurang saka 1000ppm. Adhedhasar syarat kasebut, KINKOU wis ngembangake C17300 timbal rendah lan kinerja pemotongan padha karo C17300. Kinkou uga nyedhiyakake paduan tembaga tanpa timbal C17200 .Kinerja pemotongan C17200 iki uga apik.
1. Komposisi kimia saka timbal kurang C17300
| Model | Be | Ni+Co | Ni+Co+Fe | Pb | Cu |
