Nickel Alloys

Nickel 205 ‘A’ Nickel (Electronic Grade)

Application & Characteristics 
Specified for electrical and electronic parts. Elasticity and dampening factors are sufficiently high to minimise vibrational and microphonic effects. Has sufficient strength at normal bombardment temperatures to prevent deformation during outgassing. Has high curie temperature and magneto-striction coefficient.
