Yon -286 Boulon

A-286 se yon alyaj ki gen fòs nikèl ki gen fòs ak tanperati ki wo.

 

Li gen gwo fòs sede, rezistans ak fòs ranpe anba a 650 degre, e li gen bon plastisit pwosesis ak pèfòmans soude satisfezan. Li apwopriye pou fabrike konpozan chaj-pote segondè-tanperati nan motè aero-ki travay pou yon tan long anba a 650 degre.
