forging method and Pb impregnation method are applied.
-The only materials exclusively for INTAKE and
EXHAUST of LPG and CNG
-Dual purpose materials for both high horsepower
diesel intake and exhaust

Explanation of the quality of materials
Hard particles of Co with good abrasion resistance characteristic in the high temperature and hard particles of Mo with good abrasion resistance characteristic in the normal temperature are dispersed and hardened in SORBITE base. Cu-Sn is deposited for develop an affinity for hardening base and valve
