VALVE SEATS
BRIEF INSTRUCTION
The INTAKE valve seats the combustion chamber on the intake port side of the head. Prior to that, it is opening to allow air and fuel to enter the combustion chamber. In take valves usually do not suffer as severely as exhaust valve seats which see combustion chamber temperatures. The EXHAUST valve seats we have a more severe environment because the valve seat is seeing combustion chamber temperatures, which on a normally asperated engine, can easily be at 1350F; on certain engines this can run even higher. Exhausted valve seats must resist against permanently bonded, high pressure, high temperature & reducing friction and wear.
TECHNICAL INFO
Aza Absolute’s unique material structure provide peak performance due to following advantages, Tungsten has melting point of 3,422 °C with low thermal expansion and high melting point and Tensile strength. Tungsten is a good material for applications like nuzzles including the aerospace and truck engine industries. And Nickel is a silvery-white metal with a slight golden tinge This crystal structure is stable to pressures of at least 70 GPa. Nickel belongs to the transition metals and is hard and ductile. And Cobalt is primarily used as the metal, in the preparation of Magnetic, wear-resistant and high-strength alloys. And Silicon high melting and boiling points of 3265 °C, that could absorb high mechanical stress.
